In most cities and counties, permits will be required for the installation of electrical circuits or the construction of exterior surfaces
(decks and gazebos). In addition, some communities have adopted residential barrier codes which may require fencing and/or selfclosing gates on the property to prevent unsupervised access to a pool (or spa) by children under 5 years of age. Your Hot Spot
Spa is equipped with a locking cover that meets the ASTM F1346-91 Standard for Safety Covers and as a result, is usually exempt
from most barrier requirements. As a general practice, your local Building Department will inform you of any applicable barrier
requirements at the time a permit is obtained for the installation of an electrical circuit. Your Hot Spot Spa Dealer can provide
information on which permits may be required.

SAFETY INFORMATION
IMPORTANT SAFETY INSTRUCTIONS
READ AND FOLLOW ALL INSTRUCTIONS
AVOIDING THE RISK TO CHILDREN
WARNING:
• RISK OF CHILD DROWNING. Extreme caution must be exercised to prevent unauthorized access by children. To avoid accidents,
ensure that children cannot use a spa unless they are supervised at all times.
• To reduce the risk of injury, do not permit children to use this product unless they are closely supervised at all times.
• To reduce the risk of injury, lower water temperatures are recommended for young children. Children are especially sensitive to hot water.
DO:
• Make sure you always lock the child resistant locks after using the spa for your children’s safety. Every Hot Spot® Spa is equipped with a
locking cover that meets the ASTM F1346-91 Standard for Safety Covers.
• Test the water temperature with your hand before allowing your child to enter the spa to be sure that it’s comfortable. Children are
especially sensitive to hot water.
• Remind children that wet surfaces can be very slippery. Make sure that the children are careful when entering or exiting
the spa.
DON’T:
• Allow children to climb onto the spa cover.
• Allow children to have unsupervised access to the spa.
AVOIDING THE RISK OF ELECTROCUTION
Risk of electrocution
• Connect only to a grounded source.
• Do not bury the power cord. A buried power cord may result in death or serious personal injury due to electrocution if direct burial-type
cable is not used, or if improper digging occurs.
• A ground terminal (pressure wire connector) is provided on the control box inside the unit to permit connection of a minimum No. 10 AWG
(6mm2) solid copper bonding conductor between this point and any metal equipment, metal water pipe, metal enclosures of electrical
equipment, or conduit within five feet (1.5 m) of the unit as needed to comply with local requirements.
WARNING:
• To reduce the risk of electrical shock, replace a damaged cord immediately. Failure to do so may result in death or serious personal injury
due to electrocution.
• Your spa is provided with a Ground Fault Circuit Interrupter for user and equipment protection. To ensure proper operation of this
important safety device, test according to the following instructions per electrical configuration.
Cord-Connected 115 volt, 15 and 20 amp models: The GFCI is located at the end of the power cord. Before each use, with the unit
operating, push the TEST button. The unit should stop operating and the GFCI power indicator will go out. Wait 30 seconds and then
reset the GFCI by pushing the RESET button. The GFCI power indicator will turn on, restoring power to the spa. If the interrupter does not
perform in this manner, there may be an electrical malfunction and with it, the possibility of an electric shock. Disconnect the power until
the problem has been corrected.
230 volt, permanently installed or converted models:
• A ground terminal is provided on the terminal block located inside the control box. To reduce the risk of electric shock, connect this
terminal to the grounding terminal of your electrical service or supply panel with a continuous green, insulated copper wire. The wire must
be equivalent in size to the circuit conductors supplying the equipment. In addition, a bonding terminal (pressure wire connector) is
provided on the outside of the control box for bonding to local ground points. To reduce the risk of electric shock, this connector should
be bonded with a No. 10 AWG solid copper wire to any metal ladders, water pipes, or other metal within 5 feet (1.5 m) of the spa to
comply with local requirements. The means of disconnection must be readily accessible, but must be installed at least 5 feet (1.5 m) from the spa.
• Your spa is provided with a suitably rated circuit breaker to open all ungrounded supply conductors.
• Your spa uses ground fault circuit interrupters in the electrical subpanel. Before each use of the spa and with the unit operating, push the
Test button on each breaker. The switch should click over to the “Trip” position. Wait 30 seconds and reset each GFCI breaker by
switching it completely off and then completely on. The switch should then stay on. If either of the interrupters does not perform in this
manner, it is an indication of an electrical malfunction and the possibility of an electric shock. Disconnect the power until the fault has been
identified and corrected.
Safety Information
Page 1
DANGER: RISK OF ELECTRICAL SHOCK
• Install at least 5 feet (1.5 m) from all metal surfaces. A spa may be installed within 5 feet of a metal surface if each metal surface is
permanently connected by a minimum No. 10 AWG (6mm2) solid copper conductor attached to the wire ground connector on the terminal
box that is provided for this purpose if in accordance with National Electrical Code ANSI/NMFPA70-1993.
• Do not permit any electrical appliances, such as a light, telephone, radio, or television within 5 feet (1.5 m) of a spa. Failure to maintain a
safe distance may result in death or serious personal injury due to electrocution if the appliance should fall into the spa.
DO:
• Be sure your spa is connected to the power supply correctly - use a licensed contractor.
• Disconnect the spa from the power supply before draining the spa or servicing the electrical components.
• Test the Ground Fault Circuit Interrupter(s) before each use.
DON’T:
• Use the spa with the equipment compartment door removed.
• Place electrical appliances within 5 feet (1.5m) of the spa.
• Use an extension cord to connect the spa to its power source. The cord may not be properly grounded and the connection is a shock
hazard. An extension cord may cause a voltage drop, which will cause overheating of the jet pump motor and motor damage.
• Attempt to open the electrical control box. There are no user serviceable parts inside.
RISKS TO AVOID
DANGER: RISK OF INJURY
• To reduce the risk of injury to persons, DO NOT remove suction fittings (filter standpipes) located in the filter compartment.
• The suction fittings in the spa are sized to match the specific water flow created by the pump. Should the need arise to replace the
suction fittings, or the pump, be sure that the flow rates are compatible.
• There is a danger of slipping and falling. Remember that wet surfaces can be very slippery. Take care when entering or exiting the spa.
• People with infectious diseases should not use the spa.
• Keep any loose articles of clothing or hanging jewelry away from rotating jets or other moving components.
Increased side effects of medication
• The use of drugs, alcohol, or medication before or during spa use may lead to unconsciousness with the possibility of drowning.
• Persons using medications should consult a physician before using a spa; some medication may cause a user to become drowsy, while
other medication may affect heart rate, blood pressure, and circulation.
• Persons taking medications that induce drowsiness, such as tranquilizers, antihistamines, or anticoagulants should not use the spa.
Health problems affected by spa use
• Pregnant women should consult a physician before using spa.
• Persons suffering from obesity or with a medical history of heart disease, low or high blood pressure, circulatory system problems, or
diabetes should consult a physician before using spa.
Unclean water
• Keep the water clean and sanitized with correct chemical care. The recommended levels for your Hot Spot® Spa are:
Free Available Chlorine (FAC):
3.0-5.0 ppm
Total Alkalinity:
125-150 ppm
Water pH:
7.4-7.6
Calcium Hardness:
150-200 ppm
(Refer to Water Quality and Maintenance section for complete instructions.)
IMPORTANT: Turn on the jet pump for a least ten minutes after adding ANY spa water chemicals into the filter compartment.
• Clean the filter cartridge monthly to remove debris and mineral buildup which may affect the performance of the hydromassage jets, limit
the flow, or trip the high limit thermostat which will turn off the entire spa.
AVOIDING THE RISK OF HYPERTHERMIA
Prolonged immersion in hot water can result in HYPERTHERMIA, a dangerous condition which occurs when the internal temperature of the body
reaches a level above normal (98.6°F). The symptoms of hyperthermia include unawareness of impending hazard, failure to perceive heat, failure to
recognize the need to exit the spa, physical inability to exit the spa, fetal damage in pregnant women, and unconsciousness resulting in a danger
of drowning.
WARNING:
The use of alcohol, drugs, or medication can greatly increase the risk of fatal hyperthermia in hot tubs and spas.
Page 2
Safety Information
TO REDUCE THE RISK OF INJURY:
• The water in the spa should never exceed 104°F. Water temperatures between 100°F and 104°F are considered safe for a healthy adult.
Lower water temperatures are recommended for extended use (exceeding ten minutes) and for young children. Extended use can cause
hyperthermia.
• Pregnant or possibly pregnant women should limit spa water temperatures to 100°F. Failure to do so may result in permanent injury to
your baby.
• Do not use spa immediately following strenuous exercise.
AVOIDING THE RISK OF SKIN BURNS:
WARNING:
• To reduce the risk of injury, before entering a spa the user should measure the water temperature with an accurate thermometer, since the
tolerance of temperature-regulating devices may vary by as much as ±5°F.
• Test the water with your hand before entering the spa to be sure it’s comfortable.
SAFETY SIGN
Each Hot Spot® Spa is shipped with a SAFETY SIGN in the owner’s package. The sign, which is required as a condition of Product Listing, should
be permanently installed where it is visible to the users of the spa. To obtain additional SAFETY SIGNS, contact your Hot Spot dealer and request
Part #003021.
IMPORTANT SPA INSTRUCTIONS
The following contains important spa information, and we strongly encourage you to read and apply them.
DO:
• Use and lock the cover when the spa is not in use, whether it is empty or full.
• Follow the Spa Care and Maintenance recommendations stated in this manual.
• Use only approved accessories and recommended spa chemicals and cleaners.
DON’T:
• Leave the Hot Spot Spa exposed to the sun without water or the cover in place. Exposure to direct sunlight can cause solar distress of the
shell material.
• Roll or slide the spa on its side. This will damage the siding.
• Lift or drag the vinyl cover by using the cover lock straps; always lift or carry the cover by using the handles.
• Attempt to open the electrical control box. There are no user serviceable parts inside. Opening of the control box by the spa owner will
void the warranty. If you have an operational problem, carefully go through the steps outlined in the Troubleshooting section. If you are not
able to resolve the problem, contact your authorized Hot Spot Spa Dealer. Many problems can easily be diagnosed over the telephone by
an Authorized Service Technician.

INSTALLATION INSTRUCTIONS
SITE PREPARATION
You probably have a spot picked out for your new spa, whether it’s indoors or outdoors, on a patio or on a deck. Just make sure you check the
following:
• Always put your spa on a structurally sound, level surface. A filled spa can weigh a great deal. Make certain that the location you choose
can support the weight of your filled spa.
• Don’t forget to level your spa before filling it.
• Locate your equipment compartment, which houses all of the electrical components, in a place where water will drain away from it.
Allowing water into the equipment compartment can damage the electronics, or may result in tripping your house’s circuit breaker.
• Leave yourself easy access to the Ground Fault Circuit Interrupter (GFCI) for testing. The GFCI is located at the end of the power cord, or
at the subpanel of a hard-wired spa.
• Never let water get into the subpanel or into the electrical outlet that your spa is plugged into. Consult your local code authority to
determine if an electrical outlet with a cover is required for your installation.
• Leave access to the equipment compartment for periodic spa care and maintenance.
WARNING: Damage to the spa’s equipment compartment components or internal plumbing as a result of rodent infestation is NOT
covered under your warranty!
OUTDOOR AND PATIO INSTALLATION
No matter where you install your new spa, it’s important that you have a solid foundation to support it.
Structural damage to the spa, resulting from incorrect installation or placement on an inadequate foundation,
is not covered under the spa’s limited warranty.
WARNING
If you install the spa outdoors, we recommend a reinforced concrete pad at least four inches thick. The
reinforcing rod or mesh in the pad should be attached to a bond wire.
DECK INSTALLATION
To be certain your deck can support your spa, you must know the deck’s maximum load capacity. Consult a
qualified building contractor or structural engineer. To find the weight of your spa, its contents and occupants,
refer to the Spa Specifications chart on the back cover. This weight per square foot must not exceed the
structure’s rated capacity, or serious structural damage could result.
INDOOR/BASEMENT INSTALLATION
Be aware of some special requirements if you place your spa indoors. Water will accumulate around the spa, so
flooring materials must provide a good grip when wet. Proper drainage is essential to prevent a build-up of water
around the spa. When building a new room for the spa it is recommended that a floor drain be installed. The
humidity will naturally increase with the spa installed indoors. Water may get into woodwork and produce dry rot,
mildew, or other problems. Check for airborne moisture’s effects on exposed wood, paper, etc. in the room. To
minimize these effects, it is best to provide plenty of ventilation to the spa area. An architect can help to
determine if more ventilation must be installed.
Watkins Manufacturing
Corporation recommends
that the Hot Spot® spa be
installed above ground.
Lowering the top of the spa
to ground level, or
employing decking which
raises standing level toward
the top of the spa
substantially increases the
hazard of accidental entry.
Consult a licensed building
contractor to design or
evaluate your custom
decking requirements.
Your spa dealer can help you with local information such as zoning regulations and building codes.
SPA LEVELING PREPARATION
Concrete sloped at 1 inch per 10 feet is preferred so that rain water and water spillover will run off and not puddle underneath the spa (water under
the spa for long periods of time may cause the wood to deteriorate). Other options are brick, stepping stone, or blocks.
It is important to note that soft surfaces, even when stepping stones are used to evenly distribute the weight of the spa, will have a tendency to
settle, thus resulting in an unleveled spa.
NOTE: Placing the spa on grass or dirt may increase the amount of debris which is inadvertently brought into the spa water and may cause harm
to your equipment as well as the spa surface, which is not covered under warranty.
1 inch
10 ft.
Slope 1 inch per 10 ft. for proper drainage.
Stepping stones or brick may settle
causing the spa to be unlevel.

Installation Instructions
SPA COVER INSTALLATION
• Place the cover squarely on the spa.
• Position the tie-down locks included with your cover on the side of the spa so that they are easily reached by the cover tie-down straps.
Allow for about 1/2” to 3/4” slack in the straps to make it easy to insert straps into locks and to compensate for vinyl shrinkage in cold weather.
• Attach the locks with the screws provided and insert the cover tie-down straps into the locks.
COVER INSTALLATION
NOTE: Keeping the cover in place any time the spa is not in use will reduce the amount of time the
heater operates, thereby minimizing operating costs.
DANGER. RISK OF INJURY.
• Never leave a spa uncovered or unattended.
• Never leave a spa cover unlocked.
• Do not stand, sit, or lie on the cover.

ELECTRICAL INSTALLATION
SELECTING THE VOLTAGE FOR YOUR SPA
Your spa is designed to operate at either 115 or 230 volts, 60 Hz, unless it is the MallorcaTM model which requires a dedicated 230 volt power supply.
When the spa is connected to 115 volts, the heater will provide approximately 1000 watts of heat only when the pump is operating in LOW speed
and the thermostat is calling for heat. When the spa is connected to 230 volts, the heater will provide approximately 4000 watts of heat when the
pump is operating in LOW or HIGH speed and the thermostat is calling for heat.
All electrical connections must be made in accordance with the wiring information contained in the electrical control box or on the back of the field
wiring access panel of the equipment module.
115 VOLT INSTALLATION
Spas provided with a factory- installed power supply cord are to be plugged into a grounded, grounding type, 115 volt, 15 ampere receptacle
(SorrentoTM and TobagoTM model) or 20 ampere receptacle (TrinidadTM model). No other electrical appliance or fixture can be used on this circuit.
IMPORTANT: Under NO circumstances should an extension cord be used. Use of an extension cord will seriously degrade the performance of the
equipment module and can create an electrical hazard.
230 VOLT INSTALLATION
When using 230 volt power supply, installation of a 50 amp dedicated circuit is required. Your spa must be hardwired direct to a GFCI-protected
subpanel by a licensed electrician. A wiring diagram is provided inside the equipment module showing where the connections are to be made.
ELECTRICAL REQUIREMENTS AND PRECAUTIONS
Your Hot Spot® spa has been carefully designed to give you maximum safety against electrical shock. Connecting the spa to an improperly wired
circuit will negate many of the spa’s safety features. Improper wiring may also cause electrocution, risk of fire, and other risks of injuries. Please
read and follow the electrical installation requirements and instructions for your spa completely!
115-230 VOLT CONVERSION
• SORRENTO (Model SOR) • TRINIDAD (Model TRI) • TOBAGO (Model TOB)
Refer to the following instructions to convert your 115 volt Hot Spot spa to a 230 volt spa.
NOTE: Converting the spa to 230 volts operation should only be done by an authorized service agent or a qualified electrician.
The conversion requires a subpanel (230 volt) which may be purchased from your Authorized dealer. Ask for part # 38661
1. Disconnect the power cord from the house receptacle.
2. Remove the screws and open the equipment compartment door.

OPERATING INSTRUCTIONS
START-UP AND REFILL PROCEDURES
Your Hot Spot® spa has been thoroughly tested during the manufacturing process to ensure reliability and long-term customer satisfaction. A
small amount of water may have remained in the plumbing after testing and, as a result, may have spotted the spa shell or the spa siding prior to
delivery. Before filling the spa, wipe the spa shell clean with a soft rag.
The following instructions must be read and followed exactly to ensure a successful start-up or refill.
CAUTIONS
• Do not fill the spa with hot water, as tripping of the high-limit thermostat may result.
• DO NOT CONNECT POWER TO AN EMPTY SPA. Power to the spa automatically activates critical components within the spa,
such as controls, heater, and other systems. If power is supplied to these components prior to the spa being filled, the
components will be damaged, and this may result in a non-warranty component failure.
• Do not use your spa after filling until all of the steps listed below are completed.
• Do not add chlorine if treating your spa with polyhexamethylene biguanide (Biguanide, PHMB, eg. BaquaSpa™) sanitizer.
• Before filling your spa for the first time, remove the equipment compartment door and check to ensure that the unions on either
side of the pump(s) and heater are hand-tight. Also, install the pump’s drain plug by screwing the plug(s) into the threaded hole in
the face of the pump(s). (A notice can be found attached to the control box, and the plug(s) will be found in your Owner’s Packet.)
1. Close all drains and fill the spa with water by removing the filter compartment cover, skimmer basket, weir, and filter. Then insert the end of a
garden hose into the filter hole and begin filling the spa. The water level of your Hot Spot spa should be maintained at a level one inch above
the highest jet in the spa. Reinstall the skimmer basket, weir, and filter once the spa is filled.
IMPORTANT: Watkins® Manufacturing Corporation does not recommend that the spa be filled with “softened” water, as this may damage the
spa’s equipment.
2. AFTER the spa has been filled with water and the equipment compartment door is secured, power must be applied to the spa.
• 115 volt models: Connect the GFCI to the waterproof receptacle and push the RESET button on the GFCI.
• 230 volt models: Open the door of the electrical subpanel and reset the GFCI breaker. Close and secure the subpanel door.
3. The jet pump(s), heating system and all internal plumbing will achieve a partial prime as the spa is filled. To check the operation of the jet
system and to purge any remaining air from the heating system, push the JETS button on the control pad twice (three times for Mallorca) to
make the jet pump(s) run on high speed for one minute. Once the jet system is fully operational (as indicated by strong, non-surging jets),
priming of the spa is complete. If you do not feel a steady stream of water from your jets, refer to the instructions for priming the pump in the
SPA TROUBLESHOOTING section in the back of this manual.
4. Adjust Total Alkalinity (TA) to 125 ppm, Calcium Hardness (CH) to 150 ppm, then spa water pH to between 7.4 and 7.6. These procedures are
listed in the “Water Quality and Maintenance” section.
IMPORTANT: Add spa water chemicals directly into the filter compartment with the jet pump on high speed for at least ten minutes.
OPERATION NOTE: Adjusting the Total Alkalinity as the first step is important, as out-of balance TA will affect your ability to adjust the pH
correctly and will prevent the sanitizer from operating effectively.
5. Superchlorinate the spa water by adding 1-1/2 teaspoons of chlorine (sodium dichlor) per 250 gallons of spa water. The jet pump should be
running on high speed when adding the chlorine, and remain on high to circulate the spa water for a ten-minute period.
6. Set the temperature control to the desired temperature (between 100°F and 104°F), then place the thermal cover on the spa and allow the
water temperature to stabilize (approximately 24 hours). Make sure you secure the cover in place using the cover locks. Periodically check the
spa water temperature. When the water temperature climbs above 90°F, proceed to the next step.
7. Press the Jets button twice (three times for Mallorca) and run the pump on high for 10 minutes to circulate the spa water. After the filter cycle
is complete, test the spa water for Free Available Chlorine (FAC) residual. If the residual is between 3 and 5 ppm on the test strips (found in
most chemical test kit) go on to the next step. If the residual is less than 3 ppm, superchlorinate the spa water by adding 1-1/2 teaspoons of
chlorine (sodium dichlor) per 250 gallons of spa water, while the jet pump is running on high. Run the jet pump on high to circulate the spa
water for a ten-minute period.
8. Recheck the Total Alkalinity (TA) at 125 ppm, Calcium Hardness (CH) at 150 ppm, then spa water pH at between 7.4 and 7.6.
OPERATION NOTE: Make sure you adjust your Total Alkalinity first, as an out-of-balance condition will affect your ability to adjust the pH
correctly, and will prevent the sanitizer from operating effectively. The spa is ready for use when the spa water has circulated and the
chlorine level remains between 3 ppm and 5 ppm.
11. The spa temperature is pre-programmed to reach 102F, and will normally do so within 18 to 24 hours. You may raise the water temperature by
pressing the Temp Plus (+) button on the control panel, or lower it by pressing Temp Minus (–) button. After a few hours, the water
temperature will remain within 3˚F of your selected temperature.
Operating Instructions
Page 11
OPERATION NOTES:
1. Your spa is equipped with a ten-minute timer delay on the heating/maintenance mode. Whenever the jet pump has been turned off (and a
three-degree temperature drop has occurred) or the temperature control has been turned up, it will take ten minutes before the low speed of
the jet pump and heater become activated. Always push the JETS button to turn off the jet pump when exiting the spa. In the standard 115
volt, 15 or 20 amp electrical configuration, the heating system does not operate simultaneously with the high speed pump. On the other
hand, on the 230 volt system, the heating system does operate simultaneously with the high speed pump.
2. The spa controller has an automatic one-hour “time-out” feature should the high speed jet mode be left on inadvertently. After one hour of
continuous operation, the controller will automatically return to the maintenance/heating mode.
3. The spa controller also has a six-hour “time-out” feature should the light be left on inadvertently. After six hours of continuous operation,
the controller will automatically turn the light off.
HEATING AND HYDROMASSAGE SYSTEMS
The Hot Spot® Spa uses a two-speed jet pump to operate its hydromassage jets and to circulate the spa water through the heating system (the
Mallorca is also equipped with a single speed jet pump used for jets only). The low speed mode of the pump, which is activated automatically by
the control thermostat, will cause the spa water to be drawn slowly in through the filter, the heater, and into the pump. The pump, in turn, will
push the water back into the spa through the jets. When the JETS button is pushed one time, the spa user can activate the low speed of the jet
pump. (The heater may or may not be on, depending on whether the control thermostat has indicated a demand for heat.) When the JETS
button is pushed a second time, the high speed of the jet pump will be activated. (This will automatically deactivate the heater if it is operating in
a standard 115 volt 15 or 20 amp system.)
In the 230 vollt electrical system, if a drop in the water temperature has occurred, the spa heater will operate simultaneously when the jet pump
is operating on high speed. On the other hand, in a standard 115 volt 15 or 20 amp electrical system, the spa heater will not operate
simultaneously when the jet pump is operating on high speed, even if a drop in the water temperature has occurred. In either electrical
configuration, when the high speed mode of the jet pump is turned off, the spa will enter a ten-minute “tranquil mode.” During this time the
heating system (and simultaneous operation of the jet pump at low speed) will not operate (unless the JETS button is pushed), even if the water
temperature has dropped below the control setting. Once the ten-minute period has expired, the spa controller will switch to the maintenance
mode and the heating system will be automatically activated.
The Hot Spot Spa is equipped with a state-of-the-art heating system. The system uses an exclusive “flow through” No-Fault® stainless steel
heater.
HYDROMASSAGE JETS
The larger jets in your spa allow you to re-direct the jet stream by changing the position of the nozzle.
The Air Control lever is used to change the air intensity of all jets simultaneously.
You can also regulate the force of the massage by rotating the jet face clockwise to reduce the force or counter-clockwise to increase the force.
Notice that turning off the flow to some jets increases the flow to the other jets. To avoid damage to your spa’s plumbing and components, do
not turn off more than half of these jets at the same time.
Directional nozzles come standart on the Hot Spot models, however, a dual port rotary nozzle can be placed in any jet location desired. The
directional nozzles can be removed by rotating the tabs to either side of the nozzle then grasping the nozzle and gently pulling away from the jet
faceplate.
ACCESSORY NOTE: dual port rotating nozzles are available from your Hot Spot dealer to replace the directional adjustable nozzles.
PRECISION ® JETS
Precision jets are small. They are designed to perform a soft, soothing massage on your back and shoulders. Adjust their pressure using the Air
Control lever.
AIR CONTROL SYSTEM
AIR CONTROL VALVE: Turning the Air Control lever to the MAX position allows for the same volume of air to flow to all individual jets and
Precision jets simultaneously. The jet faceplate on the larger jets is then used to control the water intensity of each hydromassage jet.
NOTE: Always turn the Air Control lever to the MIN position anytime the spa is not being used. This will help make the spa operate more quietly
and heat more efficiently when the vinyl cover is in place.
SAFETY EQUIPMENT
A. GFCI: The Ground Fault Circuit Interrupter, located on the end of the power cord (115 Volt models only), is a safety device that is designed to
sense as little as 5 milliamps of electrical current leakage to ground. It is very important to protect a GFCI from rain and other moisture.
Watkins Manufacturing Corporation recommends that the GFCI be tested before each use to ensure it is functioning correctly.
Page 12
Operating Instructions
To test the GFCI:
Cord-Connected 115 Volt, 15 or 20 Amp Models: Before each use, with the spa operating, push the TEST button (located on the front of the
GFCI). The GFCI breaker should trip to the “off” position, disconnecting power to the spa. Reset the GFCI by pushing the RESET button. The
spa will now operate normally. If the interrupter does not perform in this manner, it is an indication of an electrical malfunction and the
possibility of an electric shock. Unplug the spa until the fault has been identified and corrected.
230 Volt, Permanently installed or converted Models: The GFCI breaker is located inside the subpanel, before each use of the spa and
with the unit operating, push the Test button on each breaker. The switch should click over to the “Trip” position. Wait 30 seconds and reset
each GFCI breaker by switching it completely off and then completely on. The switch should then stay on.
B. HEATER HIGH-LIMIT SWITCH: The heater high-limit thermostat is located on the heater assembly. If for any reason the internal temperature
of the heater exceeds 120°F, the high-limit circuit will trip and turn off the spa. This is indicated on the control panel display by the code
“◆◆◆” The heater high-limit may be reset when the water temperature within the heater has cooled to approximately 110°F. Reset the heater
high-limit by simply disconnecting power to the spa for thirty seconds. The cause of the overheating must be located to prevent a recurrence.
The most common cause of limit-tripping is inadequate water flow through the heating system. This may be caused by an obstruction within
the pump water lines (filter, pump intakes or internal plumbing), the non-function of the low speed mode of the jet pump, or the malfunction of
the control thermostat. Once the cause has been identified and corrected, and the sensor has cooled, reset the switch.
C. PRESSURE SWITCH: The pressure switch is located on the heater, and is designed to prevent heater operation during a no or low flow
condition. If for any reason flow through the heater is reduced or stopped, the pressure switch will trip. This is indicated on the control panel
display by the code “◆◆◆” The most common causes of inadequate heater flow are a dirty or clogged filter, obstruction in the plumbing
lines, and non-operation of the low speed heat pump.
Additionally, the control panel display will display the code “◆◆◆” if the pressure switch senses flow through the heater when the jet pump is
not activated. Contact your Authorized Service Technician.

LIGHT CONTROL
®
Your Hot Spot spa is equipped with a low-voltage spa light. Press the LIGHT button to turn it on. Press it a second time to turn it off. For your spa
enjoyment, a blue and a red lens cover have been included with the spa’s owner’s packet. The original clear lens is not removable – the red or blue
colored lens can be snapped over the clear lens to create the desired ambiance.
The light automatically turns off after six hours.
When the light is active, the LIGHT LED on the control panel will illuminate.
FILTER CYCLES
Your spa will automatically turn the filter cycle on twice each day. When the spa is first powered up the automatic filter cycle will wait 12 hours
before starting. A six hour filter cycle using the low speed of the jet pump is the programmed default filter cycle time. The filter cycle occurs twice
a day (every 12 hours).
®
NOTE: The optional FreshWater III ozone system only works during the filter cycles.
To modify the length of the filter cycle:
A. Press and hold the Light button for approximately five seconds until the display shows “xx” where xx is a number from 0-12. This is the length
of the filter time.
B. Using the Temp Plus (+) or the Temp Minus (–) button, adjust the value as desired.
C. Pressing the LIGHT button again confirms the setting and starts a cycle immediately.
D. If the LIGHT button is not pressed again, the new filter time is stored, but the cycle is started at the next scheduled time.
The filter cycle will activate the jet pump on low speed for the entire cycle. When activated, the filter cycle LED on the display is turned on. If the
temperature exceeds the set point by three degrees F for more than three hours, the system will cancel the FILTER cycle and the filter LED will
blink for the remaining filter cycle time. Should the temperature cool down to two degrees F below the set point before the end of the cycle, the
cycle will resume for the rest of the time. Should you use the spa during the filter cycle by placing the jet pump on high speed, the FILTER LED will
blink. Once the jet pump has been shut off, a ten minute tranquil mode begins (FILTER LED will be blinking during tranquil mode) before the filter
cycle will resume. The blinking filter LED indicates that the filter cycle timer is still counting, but the cycle has been temporarily interrupted.
NOTE: The interrupted time of a filter cycle is not extended after the filter cycle resumes. Power interruptions of the spa will reset the filter cycle to
the default six hour cycle time and begin 12 hours after spa regains power.

WATER QUALITY AND MAINTENANCE
It’s important to have clean water. Water maintenance is one of the least understood, yet most important areas of spa ownership. Your dealer can
guide you through the process of achieving and maintaining perfect water in your spa, given your local conditions. Your program will depend on
your water’s mineral content, how often you use your spa, and how many people use it.
Watkins recommends that you either use an entirely chlorine-based system, or an alternative system which uses silver ions (the FreshWaterAg+®
silver ion purifier). Watkins recommends the use of HotSpring FreshWater™ products. These are available from authorized HotSpring Dealers.
GENERAL INFORMATION
THE THREE FUNDAMENTAL AREAS OF WATER MAINTENANCE:
• Water Filtration
• Chemical Balance/pH Control
• Water Sanitation
Water Sanitation is the responsibility of the spa owner, achieved through the regular and periodic (daily, if necessary) addition of an approved
sanitizer. The sanitizer will chemically control the bacteria and viruses present in the fill water or introduced during use of the spa. Bacteria and
viruses can grow quickly in undersanitized spa water.
The water’s chemical balance and pH control are also the responsibility of the spa owner. You’ll have to add chemicals to maintain proper levels of
Total Alkalinity (TA), Calcium Hardness (CH) and pH. Proper water balance and pH control will minimize scale buildup, extend the life of the spa,
and allow the sanitizer to work at top efficiency.
METHODS FOR TESTING THE SPA WATER
Accurate water testing and analysis is an important part of effectively managing your spa water. You must have the ability to test for:
• Total Alkalinity (TA)
• Calcium Hardness (CH)
• pH
• Sanitizer
Two types of testing methods are recognized and recommended by Watkins:
The Reagent Test Kit is a method which provides a high level of accuracy. The reagents come in either liquid or tablet form.
Test Strips are a convenient testing method used by many spa owners. Keep in mind that test strips are susceptible to heat and moisture
contamination, which will result in inaccurate readings.
IMPORTANT: Always read and carefully follow the directions included with the Test Kit or Test Strips to ensure the accuracy of the test results.
BASIC CHEMICAL SAFETY
When using chemicals, read the labels carefully and follow directions precisely. Though chemicals protect you and your spa when used correctly,
they can be hazardous in concentrated form. Always observe the following guidelines:
• Allow only a responsible person to handle spa chemicals. Keep them out of the reach of children.
• Accurately measure the exact quantities specified, never more. Do not overdose your spa.
• Handle all containers with care. Store in a cool, dry, well ventilated place.
• Always keep chemical containers closed when not in use. Replace caps on their proper containers.
• Don’t inhale fumes or allow chemicals to come in contact with your eyes, nose, or mouth. Wash your hands immediately after use.
• Follow the emergency advice on the product label in case of accidental contact, or if the chemical is swallowed. Call a doctor or the local
Poison Control Center. If a doctor is needed, take the product container along so that the substance can be identified.
• Don’t let chemicals get on surrounding surfaces or landscaping.
• Don’t use a vacuum cleaner to clean up chemical spills.
• Never smoke around chemicals. Some fumes can be highly flammable.
• Don’t store any chemicals in the spa equipment compartment.
HOW TO ADD CHEMICALS TO THE WATER
IMPORTANT: All spa water chemicals, including granulated dichlor, MPS, granulated pH increaser or decreaser, granulated total alkalinity
increaser, calcium hardness increaser, liquid stain and scale inhibitor, and liquid defoamer must always be added directly into the filter
compartment while the jet pump is running in high speed mode, and it must run for a minimum of ten minutes.
Water Quality and Maintenance
Page 15
To Administer Spa Water Chemicals:
1. Fold back the cover. Carefully remove and set aside the filter compartment cover.
2. Push the JET button twice to activate the jet pump’s high speed mode.
3. Carefully measure the recommended amount of chemical and slowly pour it into the filter compartment. Use care not to splash chemicals on
your hands, in your eyes, on the spa shell surface or on the siding.
4. After ten minutes, shut off the jet pump and close and lock the cover to complete the procedure. Risk of Drowning: Never leave an open spa
unattended!
WARNING: High sanitizer levels can cause discomfort to the user’s eyes, lungs and skin. Always allow the sanitizer level to fall to the
recommended range before using the spa.
IMPORTANT “SUPER CHLORINATION/NON-CHLORINE SHOCK TREATMENT” NOTE: After administering a super chlorination treatment or
non-chlorine shock to your spa, leave the cover open for a minimum of twenty minutes to allow the oxidizer gas to vent. A high concentration of
trapped oxidizer gas which may exist as a result of the shock treatment (not daily sanitation) may eventually cause discoloration or vinyl degradation
to the bottom of the cover. This type of damage is considered chemical abuse and is not covered under the terms of the limited warranty.
THE HOT SPOT® SPA WATER MAINTENANCE
PROGRAM
Each step in your water maintenance program is dependent on the completion of the previous steps. Omitting a step or failing to reach the
recommended range may cause an imbalance in your water’s chemistry. Unbalanced water chemistry can damage the spa and its components as
well as cause discomfort for the user.
FILLING THE SPA WITH WATER
A. To prevent contaminants from entering the spa, Watkins Manufacturing Corporation recommends using the FreshStart®10,000 pre-filter when
filling the spa with water. Always fill the spa through the filter compartment.
WARNING: DO NOT use the FreshStart10,000 pre-filter if you plan to use granular bromine or BaquaSpaTM as your sanitizer.
B. The FreshStart10,000 pre-filter is designed to remove unwanted contaminants such as rust, dirt, detergents and algae from the fill water.
Dissolved minerals and metals such as lead, calcium, copper and iron are not removed.
C. Instructions are included with the FreshStart10,000 pre-filter. When the spa is filled, proceed to the Start-Up and Refill Procedures on page 14.
BALANCING THE TOTAL ALKALINITY (TA)
A. The recommended Total Alkalinity (TA) for your spa water is 125-150 ppm.
B. Total Alkalinity is a measure of the total levels of carbonates, bicarbonates, hydroxides, and other alkaline substances in the water. TA is
referred to as the water’s “pH buffer”. In other words, it’s a measure of the ability of the water to resist changes in pH level.
C. If the TA is too low, the pH level will fluctuate widely from high to low. Fluctuations in pH can cause corrosion or scaling of the spa
components. Low TA can be corrected by adding Hot Spring® FreshWaterTM pH/Alkalinity Up or sodium hydrogen carbonate.
D. If the Total Alkalinity is too high, the pH level will tend to be high and may be difficult to bring down. It can be lowered by adding Hot Spring
FreshWater pH/Alkalinity Down or sodium bisulfate.
E. Once the TA is balanced, it normally remains stable, although the addition of more water with a high or low alkalinity will raise or lower the TA
reading of the water.
F. When the Total Alkalinity is within the recommended range, proceed to the next step.
BALANCING THE CALCIUM HARDNESS (CH)
A. The recommended Calcium Hardness (CH) level for your spa is 150-200 ppm.
B. Calcium Hardness is a measure of the total amount of dissolved calcium in the water. Calcium helps control the corrosive nature of the spa’s
water. That’s why calcium-low water (commonly known as “soft” water) is not recommended. It is very corrosive to the equipment, and can
cause staining of the spa shell. If the calcium level is too low, we recommend using HotSpring FreshWater Calcium Increaser to bring the
calcium hardness level to within the recommended range.
C. If the CH is too high (commonly known as “hard” water), formation of scale on the spa’s shell surface and equipment can result. CH can be
decreased by dilution – a mixture of 75% hard and 25% soft water will usually yield a reading within the correct range. If soft water is
not available or practical for you, a stain and scale inhibitor, such as Hot Spring FreshWater Stain and Scale Defense, should be added to the
spa water, according to label instructions.
D. Once the CH is balanced, it normally remains stable, although the addition of more water with a high or low calcium content will raise or lower
the CH reading of the water.
E. When the Calcium Hardness is within the recommended range, proceed to the next step.
Page 16
Water Quality and Maintenance
BALANCING THE PH
A. The recommended pH level for your spa water is 7.4-7.6.
B. The pH level is the measure of acidity and alkalinity. Values above 7 are alkaline; those
below 7 are acidic. Maintaining the proper pH level is extremely important for:
• Optimizing the effectiveness of the sanitizer.
• Maintaining water that is comfortable for the user.
• Preventing equipment deterioration.
C. If the spa water’s pH level is too low, the following may result:
• The sanitizer will dissipate rapidly.
• The water may become irritating to spa users.
• The spa’s equipment may corrode.
If the pH is too low, it can be increased by adding sodium hydrogen carbonate, or
Hot Spring® FreshWaterTM pH/Alkalinity Up, to the spa water.
D. If the pH level is too high, the following may result:
• The sanitizer is less effective.
• Scale will form on the spa shell surface and the equipment.
• The water may become cloudy.
• The filter cartridge pores may become obstructed.
If the pH is too high, it can be decreased by adding sodium bisulfate, or Hot Spring FreshWater pH/Alkalinity Down, to the spa water.
NOTE: After adding sodium hydrogen carbonate, or sodium bisulfate, wait two hours before testing the water for pH. Measurements taken too
soon may not be accurate.
E. It is important to check the pH on a regular (weekly) basis. The pH will be affected by the bather load, the addition of new water, the addition
of various chemicals, and the type of sanitizer used.
F. When the pH is within the recommended range, proceed to the final step.
MAINTAINING THE SANITIZER LEVEL
A. Sanitizer is extremely important for killing algae, bacteria and viruses, and preventing unwanted organisms from growing in the spa. At the same
time, you don’t want too high a sanitizer level, or it can irritate your skin, lungs and eyes.
B. Always maintain the sanitizer level in your spa at the recommended level for each type of sanitizer.
C. Watkins recommends only the following sanitizers:
• Sodium Dichloro-s-Triazinetrione (sodium dichlor or chlorine)
• Baqua Spa™ (please consult your Baqua Spa manual for instructions on the use of this product).
• Brominating Concentrate™ (one step granular bromine)
WARNING: DO NOT use tri-chlor chlorine, bromo-chloro-dimethyl-hydantoin (BCDMH), or any type of compressed bromine or chlorine, acid,
or any type of sanitizer which is not recommended by Watkins Manufacturing Corporation.

FRESHWATERAg+ SILVER ION SYSTEM
®
The Silver Ion system is comprised of the following products:
• FreshStart®10,000 pre-filter
• Sodium Dichlor
• Monopersulfate (MPS)
• FreshWaterAg+ silver ion purifier
FreshStart10,000 pre-filter is used when filling a spa for the first time or at refill. It attaches to a garden hose and filters out rust, dirt, detergents, algae,
and chemicals.
Sodium Dichlor (chlorine) is the only recommended sanitizer that will work in conjunction with all of the other products in this system.
Monopersulfate (MPS) is an oxidizing chemical used to prevent the buildup of contaminants, maximize sanitizer efficiency, minimize combined
chlorine and improve water clarity.
FreshWaterAg+ silver ion purifier introduces silver ions into the spa water, inhibiting bacteria growth. When combined with MPS or chlorine,
oxidizes particulates in the spa water.
It is important to follow the recommended application and maintenance programs outlined for each product’s use.
If the spa is being used over an extended period of time, such as a whole afternoon or evening, additional sanitizer will be needed.
A weekly “shock treatment” is required.
The shock treatment quickly destroys any remaining contaminants while revitalizing the silver ion cartridge, allowing the silver ions to continue to
be released into the water. Without this weekly shock treatment, the silver ion cartridge may stop releasing silver ions into the water.
To weekly “shock treat” your spa you may use either MPS or sodium dichlor. It will require much less sodium dichlor to administer the shock
treatment than MPS (1 teaspoon of sodium dichlor has oxidizing capabilities comparable to 2 tablespoons of MPS). Sodium dichlor may be a
more appropriate weekly shock for those users that experience heavy bather load conditions.
IMPORTANT NOTE: MPS is an oxidizer, not a sanitizer.

EVERFRESH® WATER CARE SYSTEM
The EverFresh water care system is comprised of the FreshWaterAg+ silver ion system and the FreshWater® III high output ozone system.
•
FreshWaterAg+ silver ion System (see FreshWaterAg+ silver ion system on previous page)
•
FreshWater III high output ozone system uses Corona Discharge technology to produce a high concentration of
ozone, which is injected into the spa water.
FRESHWATERAg+ SILVER ION PURIFIER REPLACEMENT INSTRUCTIONS
®
When replacing the FreshWaterAg+ silver ion purifier (every four months), it is highly recommended that the spa be drained and refilled at the same
time. After refilling the spa with water, balance the Total Alkalinity (TA), Calcium Hardness (CH) and pH to the recommended levels. Shock the spa
by adding sodium dichlor.
1.
Release the cover locks and fold back the cover.
2.
Remove the filter compartment cover.
3.
Make sure the filter compartment is clear of any floating objects.
4.
Drain the spa using the recommended procedures found in the Owner’s Manual.
5.
Push down slightly and turn filter basket counterclockwise to unlock, then pull out the basket and weir.
6.
Grab handle and lift filter straight up and out.
7.
Attach the handle to the new FreshWaterAg+ silver ion purifier.
8.
Insert the FreshWaterAg+ silver ion purifier into the bottom of the filter. Allow the handle to rest on the inside lip of the filter.

9. Carefully replace the filter, the filter basket and weir.
10. Fill the spa as recommended (see Start-Up and Refill Procedures).
11. Replace the filter compartment cover (if equipped).
12. Fold the cover back into place.
WARNING: Never use the spa with the filter cartridge or filter standpipe removed!
SILVER IONS QUESTIONS AND ANSWERS
Question: How are the silver ions actually added to the water?
Answer: The silver ion cartridge contains ceramic beads that are infused with silver. By placing the cartridge in the filter standpipe, it is
subjected to the flow of water created by the operation of the jet pump . The flowing water, through a chemical erosion process,
carries with it the silver ions necessary to add a sanitizing residual to the spa water.
Question: What happens if I do not add the weekly shock treatment?
Answer: The contaminants in the water may coat the silver ion cartridge’s ceramic beads, blocking the silver ions’ release into the water. When
this occurs, there will be no residual of silver ions present in the water, eliminating them from the sanitizing process.
Question: How often should the FreshWaterAg+ silver ion purifier cartridge be replaced?
Answer: The cartridge must be replaced every four months. Please refer to the instructions provided with each FreshWaterAg+ silver ion purifier
cartridge.
Question: Why can’t I use bromine or biguanides instead of MPS or chlorine?
Answer: Bromine and biguanides will chemically react with the sanitizing action of the silver ions. This will eliminate their beneficial sanitizing
effect.
DOS AND DON’TS
•
•
•
•
•
•
•
•
DO check your MPS or dichlor chemical level prior to each use.
DO change the FreshWaterAg+ silver ion purifier every 4 months.
DO test Total Alkalinity and pH weekly.
DO check your sanitizer prior to each use.
DO use MPS for spas only, such as Hot Spring® MPS Chlorine-Free Oxidizer.
DO store all chemicals in a tightly sealed container in a cool, dry place.
DON’T use bromine, sodium bromide or biguanides. These are an active sanitizer and will combine with the silver ions to inactivate them.
DON’T use a water clarifier. Clarifiers will cause the spa water to become cloudy.
CHLORINE (SODIUM DICHLOR)
A. Sanitizing chemicals, such as chlorine, are oxidants that kill bacteria and viruses in the
water. The Free Available Chlorine (FAC) is a measure of the amount of unused chlorine
available to sanitize the spa. The recommended FAC for your spa water is 3.0-5.0 ppm.
B. Watkins Manufacturing Corporation recommends the use of HotSpring® FreshWaterTM
Concentrated Chlorinating Granuals (sodium dichlor) for sanitizing the water. Sodium
dichlor is preferred because it is totally soluble, dissolves quickly and is nearly pH neutral.
C. Maintaining the proper level of chlorine during use is extremely important.
D. If the FAC is too low, bacteria and viruses can grow rapidly in the warm water. Increase
the FAC by adding granulated sodium dichlor.
E. If the FAC is too high, the water can cause discomfort to the user’s eyes, lungs and skin.
Simply allow some time to pass. The FAC level will drop naturally over time.
F. When the Free Available Chlorine is within the recommended range, the spa is ready to be
enjoyed.
WARNING: There are several forms of stabilized chlorine available for use in spas and
swimming pools and each form has specific chemical characteristics. It is extremely
important that the one you choose is specifically designed for use in spas. Use of an incorrect product such as tri-chlor, which has a very low
pH (2.6), dissolves too quickly in hot water resulting in extremely high levels of chlorine, and is designed for concrete or plaster swimming
pools, WILL cause damage to your spa. Use of a liquid, or any type of compressed bromine or chlorine, acid, or any type of sanitizer which is
not recommended by Watkins Manufacturing Corporation WILL damage your spa and is specifically not covered under the terms of the
limited warranty.
Page 20
Water Quality and Maintenance
IMPORTANT: Granulated chlorine (sodium dichlor) will degrade if stored improperly. We recommend purchasing chlorine in one, two, or five
pound containers and storing it in a cool, dry place to maintain its potency.
SUPER CHLORINATION
Super Chlorination is designed to “burn-off” the build-up of chloramines (used chlorine), to eliminate the chlorine smell and to allow the proper
level of free chlorine to be maintained.
When giving your water a super chlorination treatment, open the cover at least half way for twenty minutes to allow the chlorine gas to vent off.
The high concentration of chlorine gas which may exist as a result of super chlorination (not daily sanitation) may eventually cause discoloration or
degradation to the bottom of the cover, which would not be covered under the terms of your warranty.
IMPORTANT: Always allow the Free Available Chlorine to fall below 5 ppm before using the spa.
WARNING: Never leave an open spa unattended, especially if there are children present!
BUILDING A SANITIZER ROUTINE
During the first month of ownership, measure the sanitizer residual daily in order to establish standards for User Load and Usage Time versus
Sanitizer Needed.
• The User Load of the spa is the number of times anyone enters the spa.
• The Usage Time is simply the amount of time a user spends in the spa.
• Sanitizer Needed is the amount of Free Available Chlorine (FAC) needed to accommodate the number of users and their combined usage
time.
For example, two spa users who regularly use the spa once an evening for twenty minutes create a specific and somewhat consistent demand on
the sanitizer. During the first month of ownership, these two users can determine exactly how much sanitizer to use in order to maintain the proper
residual. If, at any time, the user load and/or usage pattern changes dramatically (invited guests), the amount and frequency of sanitizer required
increases dramatically.
The greater the usage time, or the bather load, the faster the residual value is diminished.
SUPPLEMENTAL WATER MAINTENANCE
Proper water sanitation and mineral balance (pH control) are absolutely essential for a complete spa water maintenance program. Here are three
other popular water additives that are optional:
Mineral Deposit Inhibitors
As water evaporates from your spa and new water is added, the amount of dissolved minerals will increase. (Minimize evaporation by keeping the
cover on the spa whenever possible.) The spa water may eventually become “hard” (Calcium Hardness too high) enough to damage the heater by
calcifying its surface. Proper pH control can minimize this.
Normal soap build-up will require water replacement regularly enough that mineral deposits normally are not a problem.
Occasionally, high iron or copper content in the water may produce green or brown stains on the spa. A mineral deposit inhibitor, such as Hot
Spring® FreshWater® Stain and Scale Defense, may help to reduce these metals.
NOTE: Well water may contain high concentrations of minerals. The use of a low water volume, extra-fine pore water filter (in-line pre-filter such as
the FreshStart®10,000 pre-filter) will help to remove many of the larger particles during the filling of the spa. In-line pre-filters can be purchased at
your local Hot Spot® Spa Dealer.
Foam Inhibitors
Spa water requires changing due to the build-up of soap in the water. Typically, soap will cause the spa water to foam when the jets are used.
Soap is introduced into the spa water from two sources; users’ bodies, which retain a soap residue after showering, and swimming apparel, which
retains soap after washing.
Foam inhibitors, such as Hot Spring FreshWater Defoamer, can suppress foam, but cannot remove soap from the water. Soap is very difficult to
remove from the water because soap is not oxidized by any chemical added to the spa. Only ozone can oxidize soap.
Eventually the soap build-up in the water will be concentrated, resulting in an unclean feeling on the bather’s skin, which is impossible to remedy.
When this occurs, it’s time to drain and refill the spa. Depending on the soap input, the water should last about 4 months before needing to be
drained.
OZONE
The FreshWater® III high output ozone system is the only ozone purification system approved for installation in your spa. The FreshWater III ozone
system utilizes Corona Discharge (CD) technology to produce a higher concentration of ozone than is produced by competing ultraviolet light (UV)
ozone systems.
Water Quality and Maintenance
Page 21
The under-the-skirt mounted FreshWater III high output ozone system unit offers less-visible installation and is less susceptible to the effects of
freezing temperatures. To access it for inspection, remove the equipment compartment door to check the unit operation (this is usually done prior
to disconnecting the power to the spa before draining). Simply listen for the buzz of the transformer to verify operation of the FreshWater III high
output ozone system.
The FreshWater III high output ozone system greatly enhances the quality of the spa water when used to supplement the spa owner’s regular
water maintenance program. Contrary to some information circulated throughout the pool and spa industry regarding ozone systems, ozone CAN
NOT be used as a single-source sanitizer, water clarifier, anti-foamer, and mineral chelating agent. A secondary-source sanitizer must be used to
maintain 2.0 ppm (2.0 mg/L) of Free Available Chlorine (FAC). Watkins Manufacturing Corporation recommends that a chemical maintenance
program based on recognized and documented industry standards still be followed when using an ozone purification system to assure water
sanitation and the highest quality purified water.
Cleaning the Ozone Injector
On occasion, a mineral build-up may clog the ozone injector causing a lack of flow or low flow of ozone bubbles. To prevent this, refer to the
following instructions to clean the injector:
1. Disconnect power to the spa.
2. Access the equipment compartment.
3. Locate the ozonator in the equipment compartment and unplug the ozonator from the control box.
WARNING Nitric acid accumulates in the air lines of the ozonator and
injector. Nitric acid will cause severe chemical burns if direct skin
contact is made, so always wear protective gloves, glasses and
clothing when working on the ozonator or injector lines. To
prevent inhalation or ingestion of the nitric acid, DO NOT blow or
inhale with your mouth to any of the adapters, fittings or tubing of
the ozonator or injector air lines.
WARNING
4. Place 16 ounces of white vinegar into a container such as a cup or bucket. Place the container on the equipment compartment floor. NOTE:
White vinegar will not damage any of the spa components.
5. Carefully loosen the long Norprene® tubing to the bottom of the ozonator. A liquid substance may be found inside the tubing. If a liquid
substance is present, BE CERTAIN NOT TO COME INTO CONTACT WITH THE LIQUID (SEE WARNING ABOVE).
6. Place the end of the tubing into the vinegar, making certain that the end of the tubing sits at the bottom of the container.
7. Reconnect power to the spa.
8. Run the spa until all 16 ounces of the vinegar are gone. This should allow an ample flow of vinegar to be run through the injector and clear the
blockage.
9. Disconnect power to the spa.
10. Remove the empty cup or bucket.
11. Reinstall the tubing to the bottom of the ozonator.
12. Plug the ozonator into the control box.
13. Close the equipment compartment door.
14. Reconnect power to the spa.
IMPORTANT: When using the FreshWater® III high output ozone system, the circulation cycle must be activated to ensure adequate ozone
circulation. Refer to the circulation cycle in the HEATING AND HYDROMASSAGE SYSTEM section for more information.
DOS AND DON’TS
• DON’T use swimming pool (muriatic) acid to lower pH.
• DON’T splash pH increaser additives on the siding.
• DON’T use Compressed Sanitizers.
The use of bromine sticks or tablets in floaters, which may become entrapped in a lounge or cooling seat (or sink to the spa floor), have been
shown to cause discoloration of or surface distress to a spa’s shell.
• DON’T use a floater type sanitization system as a low or no maintenance solution to your spa maintenance program.
The spa shell can easily withstand the effects of a properly administered sanitizer. Floating dispensers can become trapped in one area and cause
an over-sanitization (or chemical burn) of that particular area.
Page 22
Water Quality and Maintenance
If the dispenser setting is too high, the high concentration can discolor the spa shell and damage the underside of the cover.
Automatic floating dispensers have a tendency to either over-brominate or under-brominate as the rate of erosion varies greatly. Damage to the
spa and cover can occur very quickly.
WARNING: Watkins Manufacturing Corporation DOES NOT recommend the use of any floating chemical dispenser. Damage to the spa shell
or components caused by a floating chemical dispenser is specifically not covered under the terms of the limited warranty.
• DON’T use a sanitizer which is not designed for spas.
• DON’T use household bleach (liquid sodium hypochlorite).
• DON’T broadcast or sprinkle the chemicals onto the water surface. This method may cause chemically-induced spa surface blistering
(chemical abuse).
• DO add all chemicals slowly into the filter compartment with the jet pump operating on high speed for ten minutes.
• DO use special care if using baking soda to clean either the interior or exterior plastic surfaces.
• DO use only a granular form of sanitizer.
COMMON WATER CHEMISTRY QUESTIONS
Question: Why can’t I use a floater to sanitize my spa water?
Answer: Watkins Manufacturing Corporation does not recommend the use of a floater for three reasons:
1. The floater is unable to control the rate at which the sanitizer is dissolved into the water. When a floater is first placed in a spa, the sanitizer
level can be extremely high. High sanitizer levels can chemically burn or discolor the spa’s shell or the underside of the cover. Then, after a
period of time, the sanitizer level dispensed by the floater will fall to near zero. A low sanitizer level will allow viruses, bacteria, or algae to grow.
2. Floaters tend to stay in one area of the spa most of the time (usually over the cool-down seat), causing this area to be exposed to extreme
sanitizer levels.
3. The floater may allow pieces of the highly concentrated sanitizer to fall out and settle on the floor or seat of the spa shell. These pieces of
sanitizer will chemically burn (blister) the spa shell. Although your spa shell is specifically designed to resist the effects of spa chemicals, no
spa surface can withstand this type of highly concentrated chemical. Remember, chemical abuse is specifically not covered under the terms
of the warranty.
Question: When I open my spa, I smell chlorine. How do I get rid of this smell?
Answer: There are two types of chlorine in your spa. The first is the Free Available Chlorine, which is the chlorine available to sanitize your spa.
This Free Available Chlorine does not have an odor. The second is Chloramine, which is residue from chlorine already expended. Chloramines
have a strong chlorine odor. The smell from Chloramines can be eliminated by “shocking” the water. If you smell chlorine in the water, your spa is
reminding you to add a shock treatment.
Question: Why can’t I fill my spa with soft water?
Answer: Soft water is essentially the same as regular water except that most or all of the calcium has been replaced by sodium. Soft water may
be corrosive to the heater and other components. Replacement of spa components damaged by soft water is extremely expensive.
Question: I am trying to reduce the number of chemicals to which my family is exposed. Do I really need to use so many chemicals and in such
large amounts?
Answer: While over-exposure to any chemical can be unhealthful, many low levels of chemicals are effective and beneficial. In the case of spa
water, the chemicals recommended in the Hot Spot® Spa Water Maintenance program are needed to protect the user from water-borne pathogens
(disease-causing microbes) and to prevent corrosion of spa components.
Question: Why isn’t water chemistry damage covered by the warranty?
Answer: The chemical levels and water quality of the water in the spa are under your direct control. With proper basic care, the spa will provide
many years of hot water relaxation. If you are unsure about any chemical or its usage in the spa, contact your Authorized Dealer or Watkins
Manufacturing Corporation.
WATER TERMINOLOGY
The following chemical terms are used in this Water Quality and Maintenance section. Understanding their meaning will help you to better
understand the water maintenance process.
Bromamines: Compounds formed when bromine combines with nitrogen from body oils, urine, perspiration, etc. Unlike chloramines, bromamines
have no pungent odor and are effective sanitizers.
Bromine: A halogen sanitizer (in the same chemical family as chlorine). Bromine is commonly used in stick, tablet, or granular form. See the DO’s
and DON’Ts of Spa Water Maintenance for additional information.
Calcium Hardness: The amount of dissolved calcium in the spa water. This should be approximately 150-200 ppm. High levels of calcium can
cause cloudy water and scaling. Low levels can cause harm to the spa equipment.
Water Quality and Maintenance
Page 23
Chloramines: Compounds formed when chlorine combines with nitrogen from body oils, urine, perspiration, etc. Chloramines can cause eye
irritation as well as having a strong odor. Unlike bromamines, chloramines are weaker, slower sanitizers.
Chlorine: An efficient sanitizing chemical for spas. Watkins Manufacturing Corporation recommends the use of sodium dichlor-type granulated
chlorine. This type is preferred because it is totally soluble and nearly pH neutral.
Chlorine (or Bromine) Residual: The amount of chlorine or bromine remaining after chlorine or bromine demand has been satisfied. The residual
is, therefore, the amount of sanitizer which is chemically available to kill bacteria, viruses and algae.
Corrosion: The gradual wearing away of metal spa parts, usually caused by chemical action. Generally, corrosion is caused by low pH or by water
with levels of TA, CH, pH or sanitizer which are outside the recommended ranges.
DPD: The preferred reagent used in test kits to measure the Free Available Chlorine.
Halogen: Any one of these five elements: fluorine, chlorine, bromine, iodine and astatine.
MPS: Monopersulfate is the non-chlorine oxidizer used with the FreshWaterAg+® silver ion purification system.
Oxidizer: The use of an oxidizing chemical is to prevent the buildup of contaminants, maximize sanitizer efficiency, minimize combined chlorine,
and improve water clarity.
Pathogen: A microorganism such as bacterium that cause disease.
pH: The measure of the spa water’s acidity and alkalinity. The recommended pH for the spa water is 7.4 to 7.6. Below 7.0 (considered neutral), the
spa water is too acidic and can damage the heating system. Above 7.8, the water is too alkaline and can result in cloudy water and scale
formation on the shell and heater.
ppm: The abbreviation of “parts per million”, the standard measurement of chemical concentration in water. Identical to mg/l (milligrams per liter).
Reagent: A chemical material in liquid, powder, or tablet form for use in chemical testing.
Sanitizer: Sanitizers are added and maintained at recommended residuals to protect bathers against pathogenic organisms which can cause
disease and infection in spa water.
Scale: Rough calcium-bearing deposits that can coat spa surfaces, heaters, plumbing lines and clog filters. Generally, scaling is caused by mineral
content combined with high pH. Additionally, scale forms more readily at higher water temperatures.
Shock Treatment: Also known as “super-chlorination” when chorine is used. Shock treatment is a process of adding significant doses of a quick
dissolving sanitizer (sodium dichlor is recommended) to oxidize non-filterable organic waste and to remove chloramines and bromamines.
Total Alkalinity: The amount of bicarbonates, carbonates, and hydroxides present in spa water. Proper total alkalinity is important for pH control. If
the TA is too high, the pH is difficult to adjust. If the TA is too low, the pH will be difficult to hold at the proper level. The desired range of TA in spa
water is 125 to 150 ppm.

MAINTENANCE AND SPA CARE
FILTER MAINTENANCE
FLOATING
WEIR
At least once a week, check and clean the skimmer basket and weir
to ensure proper filter flow. Remove leaves, foreign matter, and debris.
It is very important to keep your spa filter cartridge clean and free of
particles to ensure proper water flow. A clean filter permits the
hydrotherapy system to function properly and also allows more
efficient filter cycles. Depending on how frequently your spa is used,
we recommend cleaning the spa filter cartridge every four weeks. If
this is not done, the filter may clog and restrict water flow, which
causes improper filtration and poor jet performance.
BASKET
FILTER
CARTRIDGE
PLEATS
WARNING: The frequency and duration of use, and the number of

Turn the spa OFF or turn the power to the spa OFF, then proceed as follows:
1. Push down slightly and turn filter basket counterclockwise to unlock, then pull the basket and weir out.
2. Carefully pull up the filter cartridge and bring it out of the spa.
3. Rinse cartridge using a garden hose. Rotate and separate filter pleats while spraying water to remove all debris possible. Let the filter dry and
then look for calcium deposits (scaling) or an oil film. If you find these, you will need to deep clean your filter cartridge with a “spa filter
cleaning” solution to break down and remove mineral deposits and oils.
4. To return basket and weir, insert and rotate clockwise to lock into position.
SPA LIGHT LENS INSTALLATION
For your spa enjoyment, a blue and red lens cover have been included with the spa’s owner’s package. The original clear lens is not removable - a
colored lens can be snapped over the clear lens to create the desired ambiance.
SPA LIGHT BULB REPLACEMENT
To replace the spa light bulb, disconnect power to the spa:
1. Remove equipment compartment door.
2. Locate the rear of the spa light and remove the bulb socket by turning it counterclockwise 1/4 turn.
3. Pull the bulb from the socket and replace by reversing the above steps.
CAUTION: The replacement bulb must be the same rating as the factory-installed bulb or standard automotive type #912.
CARE OF THE SPA PILLOWS
The spa pillows used on the Mallorca™ and Trinidad™ models will provide years of comfort if treated with care. They have been positioned above
the water level to minimize the bleaching effects of chlorinated water and other spa water chemicals. To extend their life, whenever the spa shell is
being cleaned, the spa pillows should be removed and cleaned. Body oils can be removed with a mild soap and water solution. ALWAYS rinse off
the spa pillows thoroughly to remove any soap residue. If the spa is not going to be used for a long period of time (that is during a vacation or if
the spa is winterized), or when the spa water is being super-chlorinated, the spa pillows should be removed until the next use of the spa.
To remove and replace the spa pillows:
1. Carefully lift one end of the pillow away from the spa shell.
2. Continue lifting one end until all pillow retainers are released from the pillow.
IMPORTANT: Just pulling the pillow straight up and out of the shell recess will eventually damage the pillow. This abuse is not covered under
warranty.
3. To reinstall the spa pillow, carefully bend the pillow slightly to allow one of the pillow retainers to slip into the recess in the back of the pillow.
4. Keeping the pillow slightly bent, slide the other pillow retainer into the recess in the back of the pillow.
5. After all the pillow retainers are in place, press the pillow down into the recess in the spa shell.
Maintenance and Spa Care
Page 25
CARE OF THE EXTERIOR
SPA SHELL
Your Hot Spot® spa has a granite like shell. Stains and dirt generally will not adhere to your spa’s surface. A soft rag or a nylon scrubber should
easily remove most dirt. Most household chemicals are harmful to your spa’s shell. Watkins® Manufacturing Corp. recommends Soft Scrub® and
Windex®. These are the only products which have passed the manufacturer’s tests. Sodium bicarbonate (baking soda) can also be used for minor
surface cleaning. Always thoroughly rinse off any spa shell cleaning agent with fresh water.
SERVICE NOTES:
1. Iron and copper in the water can stain the spa shell if allowed to go unchecked. Ask your Hot Spot dealer for a stain and scale Inhibitor to use
if your spa water has a high concentration of dissolved minerals.
2. The use of alcohol or any household cleaners other than those listed to clean the spa shell surface is NOT recommended. DO NOT use any
cleaning products containing abrasives or solvents since they may damage the shell surface. NEVER USE HARSH CHEMICALS! Damage to
the shell by the use of harsh chemicals is not covered under the warranty.
IMPORTANT: Some surface cleaners contain eye and skin irritants. Keep all cleaners out of the reach of children and use care when applying.
CARE OF THE SPA COVER
WARNING: The cover is a manual safety cover that meets or exceeds all prevailing requirements of ASTM Standards for spa safety covers
when installed and used correctly as of the date of manufacture. Non-secured or improperly secured covers are a hazard. Open the cover to its
fully open position before use.
VINYL COVER
The vinyl spa cover is an attractive, durable foam insulation product. Monthly cleaning and conditioning are recommended to maintain its beauty.
To clean and condition the vinyl cover:
1. Remove the cover from the spa and gently lean it against a wall or fence.
2. With a garden hose, spray the cover to loosen and rinse away dirt or debris.
3. Using a large sponge and/or a soft bristle brush, and using a very mild soap solution (1 teaspoon dishwashing liquid with 2 gallons of water) or
baking soda (sodium bicarbonate), scrub the vinyl top in a circular motion. Do not let the vinyl dry with a soap film on it before it can be rinsed clean.
4. Scrub the cover’s perimeter and side flaps. Rinse clean with water.
5. Rinse off the underside of the cover with water only (use no soap), and wipe it clean with a dry rag.
SERVICE NOTE: To remove tree sap, use cigarette lighter fluid (not charcoal lighter fluid). Use sparingly, and rinse with a saddle soap solution
immediately afterwards, then wipe dry.
Important reminders:
•
•
•
•
•
DO remove snow buildup to avoid breakage of the foam core from the additional weight of the snow.
DO lock cover lock straps to secure the cover when the spa is not in use.
DO NOT drag or lift the spa cover using either the flaps or the cover lock straps.
DO NOT walk, stand, or sit on the cover.
DO NOT place any metal or heat transferring object on the cover or place any type of plastic tarp or drop cloth over the cover as this may
result in a melted foam core, which would not be covered under the warranty.
• DO NOT use any lifting mechanisms, chemicals or cleaners except those recommended by Watkins® Manufacturing Corporation or its
Authorized Sales and Service Dealer
WOOD SPA CABINET
The spa cabinet on Hot Spot® spas is constructed of high-quality wood. The wood cabinet is factory-sealed with a lightly tinted stain for beauty
and protection. As with all wood products, prolonged exposure will cause discoloration and drying. Do not use wood sealers or wood furnituretype oils such as tung, teak or lemon to seal the cabinet, as they will cause the wood to blacken. Discoloration or aging of the redwood cabinet is
considered natural and is not covered by the limited warranty.
NOTE: Always test a small area (such as one or two vertical corner boards) or your spa cabinet for stain compatibility before applying a nonrecommended stain.
SIMULATED SPA CABINET (OPTIONAL)
Simulated wood consists of a rigid polymer that combines the durability of plastic, with the beauty of wood. Simulated wood won’t crack, peel,
blister, or delaminate even after prolonged exposure to the elements.
Cleaning of Simulated wood consists of simply spraying the cabinet with a mild soap and water solution to remove any stains and residue.

DRAIN
HOSE
8. Replace the equipment compartment access door.
NON-OPERATION IN COLD
CLIMATE
If the spa is to be left unused for an extended period of time in areas where
FREEZING TEMPERATURES DO NOT OCCUR, it may be desirable to turn the
heater to the lowest temperature. The automatic filter cycles will keep the spa
water clean and sparkling. When preparing the spa for use, check the water
chemistry to assure correct chlorine or bromine and pH levels.
You can keep the water in the spa during the time of year when freezing at the
spa location may occur. If a freeze condition is detected, the pump and heater will
be activated automatically to circulate the water in low speed. However,
CAUTION must be used with this approach. In the event of electrical power
interruption, regardless of the cause, the heater and pump will stop operating and

WINTERIZING YOUR SPA
If the spa is located where freezing temperatures occur, and you do not intend to
use your spa for an extended period, follow steps 1 through 7 outlined in
“DRAINING YOUR SPA” then complete the steps below:
MPORTANT: The following steps should protect your spa from freezing damage
provided these instructions are followed exactly. For maximum protection against
freeze damage to your spa, Watkins® Manufacturing Corporation recommends
contacting your local Hot Spot® dealer to schedule an in-home Propylene glycol
(anti-freeze) Winterizing Service plan.

SUCTION COVER REMOVAL
NOTE: MAKE CERTAIN ALL POWER TO THE SPA IS OFF and all water has
been drained from the spa before you continue.
1. Unscrew the Pump Drain Plug located on the front of the pump housing.
Allow all water to drain out, then replace the Pump Drain Plug.
SCREW
2. It is necessary to remove all water from interior plumbing. Remove the two
screws securing the suction cover, then remove the suction cover.
3. Close the suction with a 1-1/2” NPT “freeze plug” (available at your local
hardware store). Then use a shop vacuum to blowout the water by inserting
the hose in the bottom of the filter canister forcing water back through the
jets.
4. Loosen union on pump and leave them loose.
NOTE: Tighten unions before filling spa.
WARNING: When not in use, the spa must be covered with an insulating spa
cover. Damage caused by either sun exposure or freezing is not covered under
warranty.

SERVICE INFORMATION
GENERAL INFORMATION
Your Hot Spot® Spa has been designed to provide years of trouble-free use. As with any appliance, problems may occasionally occur that
require the expertise of a qualified service person. Though such simple repairs as resetting a GFCI switch or breaker, high limit thermostat,
or pressure switch, or replacing a light bulb may not require a service call, they may indicate that a more serious condition exists. These
conditions may require an experienced service person. Before calling for service, please refer to the Troubleshooting Guide.
NOTE: Always retain your original sales receipt for future reference.
GFCI AND HIGH LIMIT THERMOSTAT
If your spa fails to operate at any time, the following items should be checked:
1. Check the power supply to the spa.
2. Check the GFCI (located at the end of the cord in standard models or in the electrical subpanel in 30 amp converted models) and see
if it has tripped. If a GFCI has tripped, reset it. If it will not reset, this may be an indication of a ground fault (short circuit) within the
electrical components. Contact an Authorized Service Technician for a complete diagnosis.
3. If, upon checking the GFCI you find it has not tripped, check the house breaker panel and ensure the main breaker for the electrical
circuit supplying the spa has not tripped. If it has, this is an indication that either the circuit was overloaded or a ground fault exists
between the breaker panel and the spa receptacle. Contact a qualified electrician.
4. If, upon checking the main house breaker, you find no failures, the heater high-limit thermostat should be checked. Tripping of the
heater high-limit thermostat is normally a result of one or a combination of any of these problems: 1) blockage within the system
plumbing, 2) switch malfunction in the heater circuit, or 3) the low speed mode of the jet pump is not functioning.
5. If the heater high-limit has tripped, the control panel display will read “◆◆◆”. Reset the heater high-limit by allowing the water to cool
and disconnecting power to the spa for at least thirty seconds. If the heater high-limit continues to trip, contact an Authorized Service
Technician for a complete diagnosis.
If the spa does not function and the GFCI or GFCI breaker and heater high-limit have not tripped, then the problem should be referred to
an Authorized Service Technician. Refer to the Troubleshooting Guide for additional service information.
FRESHWATER® III HIGH OUTPUT OZONE SYSTEM
The FreshWater III high output ozone system is practically maintenance-free because it is located within the spa’s equipment
compartment. If bubbles are appearing at the spa’s heater return (also functions as the floor drain) but the smell of ozone is not noticeable
(the water may also appear not as clear as usual), then the operation of the ozone generator should be checked. Carefully open the
equipment compartment door (remember to use care, as power is still connected to the spa) and verify that the CD tube and its
transformer are energized (a slight buzz will be emitted from the ozone generator housing). If a slight buzz or hum is not audible, verify that
the generator is completely plugged into the spa’s control box.
If the unit is plugged in and power is connected to the spa, then the fuse (for the ozone generator) should be checked.
WARNING: Contact your Hot Spot Spa Dealer if your spa requires troubleshooting beyond the scope of this manual. Freshwater III
high output ozone systems should only be serviced by a qualified technician.
WARRANTY NOTE: Cleaning of the ozone injector is not covered under the warranty. Refer to the Ozone section of this manual for ozone
injector cleaning instructions.
The FreshWater III ozone system WILL ONLY operate when the low speed of the jet pump is on.
• During the low speed cycle, you will see bubbles escaping from the heater return, these bubbles come directly from the operating
ozone unit.
• The Circulation cycle must be activated in order to ensure adequate ozone circulation time. The Circulation cycle (when activated) will
turn the jet pump on low speed for a four-hour cycle daily. See CIRCULATION CYCLE in the HEATING AND HYDROMASSAGE
SYSTEM section of the Owner’s Manual for more information.
The FreshWater® III high output ozonator WILL NOT operate when the high speed of the jet pump is on.
• During the high speed cycle, you will also see bubbles escaping from the floor drain, however, the ozone unit is off and the bubbles that
are visible are air bubbles only!

MISCELLANEOUS SERVICE INFORMATION
The jet pump is equipped with an overload cut-off switch, which is designed to protect the pump from overheating. If the pump shuts itself off in a
new spa, it is usually the result of one, or a combination of, the following factors:
High Temperature: During the summer months, especially in warmer climates, the ambient temperature contributes to excessively high
temperatures within the equipment compartment.
Friction: Sometimes the moving parts of a new pump are tight enough to cause heat build-up due to friction. After a normal break-in period, the
pump will run cooler.
Improper House Wiring: If the spa is not connected to a dedicated circuit, or is connected to an extension cord, or the house wiring is
undersized, the pump may starve for voltage and therefore may draw more amperage and generate excessive heat. This will often cause the
circuit breaker to trip repeatedly.
IMPORTANT:
1. If the pump is shutting down due to excessive heat, make sure the equipment compartment has adequate ventilation. The air gap at the
bottom and the jet pump vent at the bottom left corner must not be blocked. Should your jet pump continue to shut off after short periods of
use, contact a qualified service technician.
2. The Hot Spot® Spa is equipped with a safety suction spring valve which will break the prime of the jet pump if both suction fittings are
obstructed.
ACTS INVALIDATING WARRANTY
The limited warranty is void if the Hot Spot Spa has been subjected to alteration, misuse or abuse, or if any repairs on the spa are attempted by
anyone other than an authorized representative of Watkins Manufacturing Corporation. Alteration is defined as any component or plumbing
change, electrical conversion, or the addition of any non-approved sanitation, or water purification device, or heating system which contributes to
a component failure, unit failure, or unsafe operating condition. Misuse and abuse shall include any operation of the spa other than in accordance
with Watkins Manufacturing Corporation printed instructions, or use of the spa in an application for which it is not designed; specifically: use of the
spa in a non-residential application; damage caused by operation* of the spa at water temperatures outside the range of 35°F and 120 °F; damage
caused by a dirty, clogged, or calcified filter cartridge; damage to the spa surface caused by the use of Tri-Chloro Chlorine, BCDMH, chemical
tablets in a floater, acid, or any other spa chemicals, or spa surface cleaners which are not recommended by Watkins Manufacturing Corporation;
damage caused by allowing undissolved spa sanitizing chemicals to lie on the spa surface (no spa surface material can withstand this kind of
abuse); damage to components or spa surface caused by improper water chemistry maintenance; and damage to the spa surface caused by
leaving the spa uncovered while empty of water and in direct exposure to sunlight (this may cause solar heating distress in warm weather regions).
These are considered abuses and may invalidate this warranty.
*Operation of the spa DOES NOT mean “use” of the spa! Watkins Manufacturing Corporation does not recommend using the spa if the water
temperature is above or below the spa’s control panel temperature range.
DISCLAIMERS
Watkins Manufacturing Corporation shall not be liable for loss of use of the Hot Spot Spa or other incidental or consequential costs, expenses, or
damages, which may include but are not limited to, the removal of a permanent deck or other custom fixture. Any implied warranty shall have a
duration equal to the duration of the applicable warranty stated above. Under no circumstances shall Watkins Manufacturing Corporation, or any
of its representatives, be held liable for injury to any person, or damage to any property, however arising.
