Important!
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 self-closing 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 SPRING dealer can provide information on which permits may be required.

WARNING
AVOIDING THE RISK TO CHILDREN
DANGER - 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.
WARNING
To reduce the risk of injury, do not permit children to use this spa 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.
• 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.
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 children 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 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
DANGER - 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. 8 AWG
(8.4 mm²) 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.
Safety Information
Page 1
• 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 (GFCI)
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 or 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.
• 115 volt 30 amp hard wired, 230 volt permanently installed or
converted models:
• A ground terminal is provided on the terminal block (TB-1, system
ground terminal) 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.
8 AWG (8.4 mm²) 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.
IMPORTANT: Failure to wait 30 seconds before resetting the GFCI
may cause the spa’s Power Indicator (on the control panel) to blink. If
this occurs, repeat the GFCI test procedure.
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. 8 AWG (8.4 mm²) 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.
• Install your spa is such a way that drainage is away from the electrical
compartment and from all electrical components.
DO:
• Be sure your spa is connected to the power supply correctly - use a
licensed electrical 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.
• Replace audio components only with identical components (if your spa
is equipped with an audio component).
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. Never replace a suction fitting with one
rated less than the flow rate marked on the original suction fitting.
• There is a danger of slipping and falling. Remember that wet surfaces
can be very slippery. Take care when entering or exiting the spa.
• Never operate spa if the suction fittings are broken or missing.
• People with infectious diseases should not use the spa.
• Keep any loose articles of clothing, long hair, or hanging jewelry away
from rotating jets or other moving components.
INCREASED SIDE EFFECTS OF MEDICATION
• The use of drugs, alcohol may cause 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.
Page 2
• Persons taking medications which 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 SPRING spa are:
Free Available Chlorine:
3.0-5.0 ppm
Total Alkalinity:
40-120 ppm
Water pH:
7.2-7.8
Calcium Hardness:
50-150 ppm
• R
efer 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 cartridges 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 (37°C). 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.
TO REDUCE THE RISK OF INJURY
• The water in the spa should never exceed 104°F (40°C). Water
temperatures between 100°F and 104°F (36°C and 40°C) 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 (36°C). Failure to do so may result in
permanent injury to your baby.
• Do not use spa immediately following strenuous exercise.
Safety Information
AVOIDING THE RISK OF SKIN BURNS
• To reduce the risk of injury, before entering a spa the user should
measure the water temperature with an accurate thermometer.
• 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 SPRING
dealer and request Part #70798.
IMPORTANT
SPA INSTRUCTIONS
The following contains important spa information, and we strongly
encourage you to read and apply them.
DO:
• Use and lock the vinyl 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.
SPA SHELL
Your HOT SPOT spa has an acrylic shell. Stains and dirt generally will
not adhere to your spa’s surface. A soft rag should easily remove most
dirt. Most household chemicals are harmful to your spa’s shell (see
below for detailed information on cleaning agents). Always rinse off any
spa shell cleaning agent with fresh water.
IMPORTANT:
1. The following products are the ONLY approved cleaning agents
for your HOT SPOT spa shell: plain water, HOT SPRING
FRESHWATER Spa Shine, or Soft Scrub®. The use of alcohol or any
other household cleaner 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, specifically: Simple Green®, Windex® or Spa Mitt. NEVER
USE HARSH CHEMICALS! Damage to the shell by use of harsh
chemicals is not covered under the warranty. Always rinse off any
spa shell cleaning agent with fresh water.
2. Iron and copper in the water can stain the spa shell if allowed to go
unchecked. Ask your HOT SPRING dealer about a Stain and Scale
Inhibitor to use if your spa has a high concentration of dissolved
minerals. (Watkins recommends FRESHWATER Stain & Scale
Defense.)
3. Keep all cleaners out of the reach of children and use care when
applying.
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 SPRING
dealer. Many problems can easily be diagnosed over the telephone by
an Authorized Service Technician.

QUICK START-UP INSTRUCTIONS
MOTO-MASSAGE (SX & TX MODELS ONLY)
The MOTO-MASSAGE jet automatically travels up and down in a
sweeping motion, simulating the natural stroking effects of a manual
massage. The intensity of the MOTO-MASSAGE jet may be adjusted by
turning the AIR CONTROL lever.
The MOTO-MASSAGE jet has been factory adjusted to provide
maximum hydromassage, and to achieve full vertical travel with its
AIR CONTROL lever in the full air volume position. Should the MOTOMASSAGE jet not achieve full vertical travel and the problem is not
a closed air control valve or clogged filter cartridge, then your HOT
SPRING Service Center should be contacted.
IMPORTANT: A slow or non-moving MOTO-MASSAGE jet may indicate
that the filter cartridge pores are obstructed with dirt, body oils, or
calcification. Follow the filter cartridge cleaning procedures in the Spa
Care and Maintenance section of this manual.
BEFORE YOU FILL YOUR SPA
Make sure your spa has been properly installed per all local codes, this
includes the location of the spa, the foundation of the spa as well as the
electrical installation of the spa. Installation instructions in the form of a
Pre-Delivery Instruction booklet can be obtained from either your HOT
SPRING dealer or online at:
www.HotSpring.com/planning-tools/pre-delivery-instructions
DO:
• Know which water treatment system you will be using and make sure
you have necessary chemicals available. Read all of the instructions
that come with the system.
• Have FRESHWATER 5-way Test Strips Available.
• Have pH/Alkalinity Up & Down available.
• Know the "Hardness" of your water, contact your dealer to help you
with this information. See Water Quality and Maintenance for more
information.
IMPORTANT: Watkins Manufacturing Corporation does not
recommend that the spa be filled with “softened” water, as this may
damage the spa’s equipment.
• Purchase the Clean Screen® pre-filter to remove unwanted
contaminants from the tap water. This is recommended, not required.
HYDROMASSAGE JETS
The larger jets in your spa allow you to re-direct the jet stream by
changing the position of the nozzle.
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.
PRECISION JETS
DON'T:
PRECISION jets are small. They are designed to perform a soft,
soothing massage on your feet, calf, back and shoulders. The Air Control
levers are used to change the air intensity of a group of PRECISION jets
simultaneously.
AIR CONTROL SYSTEM
AIR CONTROL VALVE: Turning the air control lever to the left 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 right 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.
WATERFALL VALVE (TEMPO, RELAY &
RHYTHM MODELS ONLY)
• Power up the spa until it has been filled with water! Power to the
spa automatically activates critical components within the spa, such
as controls, heater, circulation pump, 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.
• Fill the spa with hot water or cold water with cold water temperature
below 50º F (10º C)! Tripping of the high-limit thermostat may result
causing your spa to stop functioning.
DON'T:
• Use your spa after filling until all of the steps listed below START-UP
are completed!
• Add chlorine if treating your spa with polyhexamethylene biguanide
(Biguanide, PHMB, eg. BaquaSpa®) sanitizer.
The TEMPO, RELAY & RHYTHM spas are equipped with a cascading
water feature. It is activated by pressing the JETS button up to 3 times
when the jets are off and turning the waterfall valve clockwise. The flow
is regulated by turning the valve to the desired position.
When not in use turn the on/off valve to the OFF position.
Page 6
Getting Started
START-UP
5. SUPERCHLORINATE THE SPA WATER by adding 1½
teaspoons of chlorine (sodium dichlor) per 250 gallons (950 liters)
of spa water with the spa in the Cleaning mode.
All HOT SPOT spas are equipped with a Cleaning mode. When
the mode is activated, the jet pump will turn on and run for ten
minutes (used for water maintenance). To activate the “Cleaning"
mode, press the MODE ( or ) button several times until the
CLEAN menu is displayed. Press the (+) button to activate the
CLEAN mode feature.
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.
1. CLOSE DRAIN AND FILL THE SPA with water through the
filter compartment. Your HOT SPOT spa water level should be
maintained at a level one inch above the highest jet in the spa.
6. SET THE TEMPERATURE CONTROL, the spa is
pre-programmed to reach 100°F (38° C), and will normally do
so within 18 to 24 hours. You may raise or lower the water
temperature by:
• Pressing the (+) button on the control panel to raise the
temperature.
• Pressing the (-) button on the control panel to lower the
temperature.
Place the vinyl cover on the spa and allow the water temperature
to stabilize. 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 (32°C), proceed to the
next step.
To prevent tampering, you can lock your desired temperature
setting. Refer to the Operating section for details.
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, reset
the 50 amp GFCI breaker, verify the system is primed. Close
and secure the subpanel door.
3. TO CHECK THE OPERATION OF THE JET SYSTEM and
to purge any remaining air from the heating system:
TEMPO, RELAY & RHYTHM Models:
• Push the JETS button 3 times to run pumps on high speed, run
for one minute.
• Push the JETS button 2 more times to shut all the jets off.
SX & TX Models:
• Push the JETS button 2 times to run the jet pump on high
speed, run for one minute. Press JETS button one more time to
shut the JETS off.
7. ACTIVATE THE CLEAN CYCLE as described in step 5 to turn on
the CLEAN cycle to circulate the spa water. After the clean 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 the test kit) go on to the next step. If the residual is less
than 3 ppm, superchlorinate the spa water by adding 1½ teaspoons
of chlorine (sodium dichlor) per 250 gallons (950 liters) of spa
water. Activate the clean cycle again to circulate the spa water for
another ten-minute period.
Weak or surging jets are an indication of a low water level condition or
clogged filter cartridges.
IMPORTANT: Be sure the air Lever (see illustration in Spa Features
section) is open by turning clockwise until it stops. Combination jet
faces can be turned to completely shut off jet flow, these jets should
be open as well.
4. USING A TEST STRIP AND APPLICABLE CHEMICALS,
adjust Total Alkalinity (TA) to 80 ppm, Calcium Hardness (CH)
to 100 ppm, then spa water pH to between 7.2 and 7.8. These
procedures are listed in the “Water Quality and Maintenance”
section.
IMPORTANT: Always add spa water chemicals directly into the
filter compartment with the jet pump on high speed for at least
ten minutes. Adjusting the Total Alkalinity (TA) 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.
Getting Started
8. RECHECK the Total Alkalinity (TA) at 80 ppm, Calcium Hardness
(CH) at 100 ppm, then spa water pH at between 7.2 and 7.8. using
a FRESHWATER 5-way test strip.
IMPORTANT: 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 chlorine level remains
between 3 ppm and 5 ppm.
9. TEST WATER WEEKLY OR BEFORE EACH TIME
THE SPA IS USED
Page 7
PRIMING THE PUMP(S)
Upon filling or refilling the spa, if a pump is operating and water is not flowing from any
of its jets, the pump may not be properly primed. To correct, refer to the illustration below
and perform the following procedures:
• Turn off power to the spa at the breaker and remove the equipment
compartment door.
• Loosen the union on the top of the pump(s) to allow the air to escape. When
water is present, hand-tighten the union.
• Turn power back on, activate the pump and check to make sure union is
tight enough to keep it from leaking. Re-install equipment door.
NOTE: Equipment compartment illustrated below will vary depending on
spa model.

CHEMICAL SAFETY
BASIC INFORMATION
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.
IMPORTANT: Water Terminology can be found at the end of this
section.
• Always read & refer to the owner's manual for complete information.
• Test your water with a test strip once a week, or each time the spa is used.
• Add chemicals in frequent small amounts to prevent overdosing the spa.
• Use the spa only when the chlorine level is between 1-5 ppm or
manually add chlorine as needed.
• It is the spa owner's responsibility to prevent over or under
chlorination.
• Drain & refill water 2-4 times per year depending on how often you
use your spa, and how many people use it.
IMPORTANT: Remember to change your water every three to four
months.
Check with your HOT SPRING dealer to determine if water in your
region has unique qualities - such as high metal or mineral content - that
should be addressed.
Your program will depend on your water’s mineral content, how often
you use your spa, and how many people use it.

Water Quality and Maintenance
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 with you 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, liquid stain and scale inhibitor, and liquid defoamer must
always be added directly into the filter compartment while the jet pump
is running in its high speed mode, and it must run for a minimum of ten
minutes.
To Administer Spa Water Chemicals:
1. Fold back the cover. Carefully remove and set aside the filter
compartment cover.
2. On your Control Panel:
Push the MODE ( or ) button several times until the CLEAN
menu is displayed. Press the (+) button to activate the CLEAN
mode feature.
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 spa
cabinet.
4. Replace the filter compartment cover. After ten minutes, the jet pump
will automatically shut off to complete the procedure. Close and
secure the cover.
DANGER: Risk of Drowning: Never leave an open spa unattended!
IMPORTANT: After administering a super chlorination treatment or nonchlorine shock to your spa, leave the cover open for a minimum of 20
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.

FUNDAMENTALS OF
WATER MAINTENANCE
• Testing: Test the water weekly or each time the spa is used with
convenient FRESHWATER 5-way test strips or more accurate liquid/
tablet reagent test kit per instructions. Critical parameters: sanitizer
level, pH, Calcium Hardness (CH), and Total Alkalinity (TA). Store test
equipment in a dark, cool, dry place to maintain potency.
• Water Filtration: The filtration used in HOT SPOT spas helps keep
water clean by circulating sanitizer and removing waste from the spa.
Regularly inspect and clean filters for peak performance.
• Chemical Balance/pH Control: It is important to adjust the primary
water parameters (Total Alkalinity, Calcium hardness, pH) into the
recommended ranges so that they are stabilized or balanced. Balance
the water chemistry every time you fill the spa with new water and then
during the life of that body of

new spa is filled for the very
first time.
• The following three water components must be kept in balance to avoid
damage to the spa. Do balance these components in the order they
are listed here as each will help you balance the next using a minimum
amount of chemicals.
1. Calcium Hardness (CH) – CH is the measure of the amount
of dissolved calcium in the water. Low levels can make the
water corrosive and high levels cause scale formation of spa
components. The recommended CH reading is between
50 - 150 ppm. If the CH level is too high, lower it with the
VANISHING ACT calcium remover per instructions. Once in
balance, the CH reading normally remains stable until new water is
added. Great care must be taken when filling the spa from a water
softener to ensure that the calcium remains in balance and avoid
damage to the spa.
2. Total Alkalinity (TA) - TA is a measure of the water’s ability to
resist changes of pH or buffer capacity. A low TA allows the pH
to fluctuate easily. The recommended TA reading is between
40 - 120 ppm. To raise the TA, use FRESHWATER pH/
Alkalinity Up (sodium hydrogen carbonate). To lower the TA, use
FRESHWATER pH/Alkalinity Down (sodium bisulfate). Once the
TA is balanced, it normally remains stable until the next drain/
refill. We recommend you check the TA reading once per month.
Raising/lowering the TA may cause the pH readings to fluctuate
widely. Ignore the pH readings on the test strip while you are
balancing the TA.
3. pH - The pH is the measure of the acidity and alkalinity.
Maintaining the proper pH level will optimize the effectiveness of
the sanitizer, preventing damage to the spa and physical discomfort
for spa users. A low pH dissipates sanitizer, causes corrosion,
and irritates spa users. A high pH level will neutralize sanitizer,
promote scaling and cloud water. The recommended pH reading
is between 7.2 - 7.8. To lower the pH level, use FRESHWATER
pH/Alkalinity Down (sodium bisulfate). To raise the pH level, use
FRESHWATER pH/Alkalinity Up (sodium carbonate).
• Water Conditioners: Spa fill water varies from location to location and
user to user, therefore it is important to consult with your dealer for an
appropriate program.
a. VANISHING ACT – High levels of calcium and some minerals
can be removed from the water with the single use VANISHING
ACT. High calcium levels can cause scale formation on the spa
equipment and shell.
b. CLEAN SCREEN pre-filter –The CLEAN SCREEN pre-flter
should be used at every fill and top-off to remove contaminants
from the fill water, especially iron, copper, and manganese.
Many water sources including well water contain high
concentrations of minerals that can cause staining of the shell
and plastics.
c. Stain and Scale control – For water high in calcium and minerals,
it may be necessary to use an anti-scalant like Stain and Scale
control. As water evaporates from your spa and new water is
added, the amount of dissolved minerals like calcium, copper,
iron, and manganese will increase. (Minimize evaporation by
keeping the cover on the spa whenever possible.) High iron or
copper content in the water may produce green or brown stains
on the spa.
d. Foam Inhibitors - Soap is introduced into the spa water from
users’ bodies and swimming apparel and can cause the spa
water to foam when the jets are used. Low levels of calcium
hardness (soft water) can increase foaming. Although ozone
can oxidize soap residual, it may become necessary to add
Foam Inhibitors to suppress the foam. Excessive soap in the
water may require a water change to resolve.
• Oxidizers: Ozone and Monopersulfate (MPS) are oxidizers used to
prevent the buildup of contaminants, maximize sanitizer efficiency,
minimize combined chlorine, and improve water clarity. They are to be
used in conjunction with EPA registered sanitizers. The FRESHWATER III high output ozone system uses Corona Discharge technology to
produce a high concentration of ozone which is injected into the spa
water 24 hours per day. FRESHWATER Chlorine-Free Oxidizer,
Monopersulfate (MPS) is a granular oxidizing chemical.
• Sanitizers: Maintaining the recommended residual level of an EPA
registered sanitizer at all times will decrease the occurrence of unsafe
bacteria and viruses in your spa water. The recommended Free
Available Chlorine (FAC), the amount of available chlorine sanitizer,
is 3.0-5.0 ppm. A low FAC can allow bacteria and viruses to grow
rapidly in the warm water, and a high FAC can cause discomfort to the
user’s eyes, lungs, and skin. Each sanitizer carries its own instructions
regarding how much to use and when to add it to the spa water.
Consult your dealer for their recommendations and instructions on
proper sanitizing of the spa.

(OPTIONAL)
THE HOT SPOTSPA WATER
MAINTENANCE PROGRAM
FILLING THE SPA WITH WATER
Use the CLEAN SCREEN Pre-filter to remove unwanted contaminants
such as rust, dirt, detergents, and algae from the fill water. Dissolved
metals, copper, iron, and manganese are also removed. Instructions are
included with the CLEAN SCREEN Pre-filter. Always fill the spa through
the filter compartment. Do not fill your spa using water from a swimming
pool as pool chemicals are very different from those used in a spa and
can damage your spa.
ADDING CHEMICALS TO THE WATER
All spa water chemicals, including granulated dichlor, MPS, granulated
pH increaser or decreaser, granulated total alkalinity 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 its
high speed mode, and it must run for a minimum of ten minutes with the
cover off. Use the Clean button/feature to ensure that the chemicals are
properly mixed when adding.
BUILDING A SANITIZER ROUTINE
During the first month of ownership, measure the sanitizer residual
daily in order to establish a baseline of sanitizer needed vs. spa usage.
Sanitizer needed is the amount of Free Available Chlorine needed to
accommodate the number of users and their combined usage time. For
example, two spa users for twenty minutes every day creates regular
demand on the sanitizer that is used to determine how much sanitizer
to add in order to maintain the proper residual. If the usage pattern
increases dramatically with invited guests, the amount and frequency of
sanitizer required increases dramatically.
PERFORMING SUPER CHLORINATION/
NON-CHLORINE SHOCK TREATMENT
A weekly or monthly super chlorination (1.5 tsp dichlor/250 gal) or shock
(4tbs mps/250 gal) may be required of your chosen sanitation program.
Increasing chlorine to 5 ppm for 24-48 hours removes excess waste and
chloramines from the water. Sodium dichlor is 6x stronger than MPS
and may be a more appropriate for those users that experience heavy
bather load conditions. Operate all jets and leave the cover open for
a minimum of 20 minutes to allow the oxidizer gas to vent to prevent
damage and discoloration to the cover and pillows after administering
a super chlorination or shock to your spa. This type of damage is
considered chemical abuse and is not covered under the terms of the
limited warranty.
IMPORTANT: Always allow the Free Available Chlorine to fall below 5
ppm before using your spa.
DANGER: Never leave an open spa unattended, especially if there
are children present!
Water Quality and Maintenance
The EVERFRESH water care system is comprised of the following
products:
• CLEAN SCREEN Pre-filter
• FRESHWATER Concentrated Chlorinating Granules, Sodium Dichlor
• FRESHWATER Chlorine-Free Oxidizer, Monopersulfate (MPS
• FRESHWATER III high output ozone system
• FRESHWATERAg+ Silver Ion purifier
The EVERFRESH system introduces silver ions into the spa water via
erosion of silver infused beads which inhibits bacteria growth. When
combined with MPS, or chlorine, waste is oxidized and removed from
the 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.
Required: Weekly Super Chlorinate/Shock the spa to reactivate the
silver ion cartridge, allow the release of silver ions, and quickly destroy
any remaining contaminants. Without this weekly shock treatment, the
silver ion cartridge may stop releasing silver ions into the water.
IMPORTANT: Use only Dichlor sanitizer. Silver is not compatible with
bromine and biguanides. Don't use a water clarifier. Clarifiers will cause
the spa water to become cloudy.
MANUAL CHLORINE (SODIUM DICHLOR)
Watkins Manufacturing Corporation recommends the use of
FRESHWATER Concentrated Chlorinating Granules (sodium dichlor)
for sanitizing the water. Sodium dichlor is preferred because it is totally
soluble, dissolves quickly, and is nearly pH neutral. The recommended
Free Available Chlorine (FAC), the amount of available chlorine sanitize
the spa, 3.0-5.0 ppm.
If the FAC is too low: Increase the FAC by adding granulated sodium
dichlor.
If the FAC is too high: Allow time to pass and the FAC level will
naturally drop over time.
If the spa smells of chlorine: super chlorinate or shock the spa FAC
chlorine does not have an odor whereas combined spent chlorine
(chloramines) has a strong chlorine odor that can be eliminated by
shocking the water.
IMPORTANT: There are several forms of stabilized chlorine available
for use in spas and swimming pools. It is extremely important to choose
one specifically designed for spas. Use of an incorrect product such
as tri-chlor which has a very low pH (2.6) and dissolves too quickly in
hot water, results in extremely high levels of chlorine that WILL cause
damage to your spa. Use of a liquid or compressed bromine/chlorine
or unapproved sanitizer WILL damage your spa and is specifically not
covered under the terms of the limited warranty.
OZONE MAINTENANCE
Reduced or no ozone bubbles coming from heater return (clogged
ozone injector) or no ozone, clean the injector:
1. Place 16 ounces of white vinegar into a cup or bucket.
2. Carefully loosen the long tubing attached to the bottom of the
ozonator, located in the equipment compartment.
DANGER: Place the end of the tubing into the vinegar, making
certain that the end of the tubing sits at the bottom of the container.
Page 11
3. 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.
4. Reinstall the tubing to the bottom of the ozonator.
Water chemistry damage is not covered by the warranty. The chemical
levels and water quality 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.
DO:
• Add all chemicals slowly into the filter compartment with the jet pump
operating for ten minutes.
• Use special care if using baking soda to clean either the interior or
exterior plastic surfaces.
IMPORTANT: 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.
Floating dispensers can become trapped in one area and cause an oversanitization or release large chunks of sanitizer that can very quickly
chemically burn the shell and cover.
DON'T:
• Use compressed sanitizers.
• Use a floater type sanitization system as a low or no maintenance
solution to your spa maintenance program.
• Use a sanitizer which is not designed for spas.
• Use swimming pool (muriatic) acid to lower pH.
• Use household bleach (liquid sodium hypochlorite).
• Broadcast or sprinkle the chemicals onto the water surface. This
method may cause chemically-induced spa surface blistering (chemical
abuse).
VACATION WATER CARE
INSTRUCTIONS
If you plan to be away from home, follow these instructions to ensure
that the water quality of your spa is maintained:
SHORT TIME PERIODS (3-5 DAYS):
1. Adjust the pH by following the instructions outlined in the Water
Quality and Maintenance section.
2. Sanitize the water by following the shock procedures also listed in
the Water Quality and Maintenance section.
3. Lock your cover in place using the coverlocks.
4. Upon your return, sanitize the water by following the shock
procedures, and balance the pH.
LONG TIME PERIODS (5-14 DAYS):
Prior to leaving:
2. Adjust the pH as required. Sanitize the water by following the shock
procedures.
Upon your return:
3. Sanitize the water by following the shock procedures. Return the set
temperature to its original setting. The spa water will be safe for you
to use once the Free Available Chlorine residual level has dropped
below 5.0 ppm.
IMPORTANT: If you will not be using your spa for an extended period
of time (in excess of 14 days) and an outside maintenance service
(or neighbor) is not available to assist with the water maintenance,
draining or winterizing of the spa is recommended. Spas equipped with
our FRESHWATER III ozone system can extend this to 4 weeks. The
FRESHWATER III ozone system does not guard against possible freezing
damage, however.
SUPPLEMENTAL WATER MAINTENANCE
Proper water sanitation and mineral balance (pH control) are absolutely
essential for a complete spa water maintenance program. Here are two
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 stain and scale inhibitor may help to
reduce these metals.
IMPORTANT: Well water may contain high concentrations of minerals.
The use of a low water volume, extra-fine pore water filter (in-line prefilter such as the CLEAN SCREEN 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 dealer.
Foam Inhibitors
Spa water requires changing due to the buildup 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 residual after showering, and swimming apparel,
which retains soap after washing.
Foam inhibitors 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 four months before needing to be
drained.
1. At least one day before you leave, set the temperature to its
lowest level. This setting should represent an approximate water
temperature of 80°F (27°C)
IMPORTANT: Spa water oxidizers such as sodium dichlor (chlorine)
maintain their level of effectiveness substantially longer in warm water
80°F (27°C) than in hot water 101°F to 104°F (38°C - 40°C).
Page 12
Water Quality and Maintenance
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.
Calcium Hardness: The amount of dissolved calcium in the spa water.
This should be approximately 50 -150 ppm. High levels of calcium can
cause cloudy water and scaling. Low levels can cause harm to the spa
equipment.
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 and plastic 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.
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. Not a sanitizer.
Nitric Acid: The formulation of nitric acid, a highly corrosive chemical,
is a byproduct of the ozone generating process. Nitric acid is produced
in very small quantities and is readily dissolved in the water stream with
ozone.
Water Quality and Maintenance
Oxidizer: The use of an oxidizing chemical is to prevent the buildup of
contaminants, maximize sanitizer efficiency, minimize combined chlorine
and improve water clarity. See MPS and Ozone.
Ozone: Ozone is a powerful oxidizing agent which is produced in
nature and artificially by man. Ozone forms no byproducts, oxidizes
chloramines, and will not alter the water’s pH.
pH: The measure of the spa water’s acidity and alkalinity. The
recommended pH for the spa water is 7.2 to 7.8. 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.
Super-Chlorination: Also known as “shock treatment.” SuperChlorination is a process of adding significant doses of a quick dissolving
sanitizer (“dichlor” is recommended) to oxidize non-filterable organic
waste and to remove chloramines and bromamines.
Total Alkalinity (TA): 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 40 to 120 ppm.

lock will remain on to prevent unwanted tampering with the set
temperature.
LIGHT - MULTI-COLOR MENU CONTROLS
(TEMPO , RELAY & RHYTHM ONLY)
Your spa lights can display a variety of different colors as well as run
through a continuous sequence of colors (loop) at different speeds. To
activate this function the following is required:
Press the MODE ( or ) button to scroll to the TOOLS screen. Once
displayed, press the (+) button to enter the TOOLS submenu. Press the
MODE ( or ) button to scroll to LIGHT screen, press the (+) button to
enter DIM, screen. Press the (+) button or (-) button in the DIM screen to
adjust the brightness of the lights. Press the MODE () button to scroll
to Color screen. Press the (+) button or (-) button in the COLOR screen
as many times as desired to toggle through the different light colors.
Press the MODE () button to scroll to Loop screen. Press the (+)
button or (-) button in the LOOP screen to select a continuous sequence
of colors, the higher the loop number the faster the color sequence will
run. Press the MODE () button to scroll to EXIT screen. Press the (+)
button in the EXIT screen to exit the LIGHT menu.
If the light is turned off while in the LOOP or COLOR mode, the same
mode will exist when the light is reactivated. You will see a flashing light
icon whenever your LOOP mode and light are turned on.
SUMMER MODE (OPTIONAL ON SX & TX
MODELS ONLY)
If your spa is equipped with a circulation pump it will also have a
Summer Mode timer. The Summer Mode timer can be activated during
extremely hot summer months if it becomes difficult to maintain water
temperatures low enough for comfort. Upon switching to the ON mode,
the circulation pump (which can add heat to the water through normal
operation) and heater will immediately shut down for the next eight
hours. Additionally, the summer mode display on the control panel
will activate and remain active for as long as the summer mode is on.
Following this eight hour period, the circulation pump and heater will
automatically re-start and will operate normally for the next sixteen
hours. The circulation pump and heater will continue to turn off for an
eight hour period every day that the timer remains in the ON position.
In this way, the amount of heat transferred to the spa water will be
minimized. When the outside temperatures begin to cool, the Summer
Mode timer should be turned to the OFF position (the summer mode
icon on the main display will shut off). This is the efficient 24 hour
circulation mode that keeps the heater operation and operating costs to
a minimum during colder/heavier usage months.
NOTE: Whenever power is disconnected and then reconnected to
the spa, the Summer Mode timer will reset starting with the 8-hour
shutdown mode. If a different 8-hour shut down time is desired,
deactivate the Summer timer Mode, then reactivate at the beginning of
the desired eight-hour shut down time.
IMPORTANT: The Summer Mode will not lower the spa’s water
temperature below the ambient air temperature.
Page 15
To activate the Summer Mode, simply follow these steps:
1. Set the temperature control to 80°F (26°C) if desired to prevent the
heater from turning on during cooler times.
2. On the control panel press the MODE ( or
) button until TOOLS is displayed. Then
press the (+) button to enter the TOOLS
submenus. Press the MODE ( or )
button in the TOOLS submenu until SUMMR
is displayed on the screen. Press the (+) button to activate the
Summer Timer mode. The Moon & Stars icon is on when in Summer
Timer Mode.
The Summer Mode must be deactivated when cooler temperatures
return. To do this, simply follow step 3.
3. To shut the Summer Mode off, press the MODE ( or ) button
until TOOLS is displayed. Then press the (+) button to enter
the TOOLS submenus. Press the MODE ( or ) button in
the TOOLS submenu until SUMMR is displayed on the screen.
Press the (-) button to deactivate.
SLEEP MODE (NON CIRCULATION PUMP MODELS ONLY)
The Sleep Mode operation is a feature that minimizes pump operation
during quiet evening hours. For example, if Filter Cycle 1 (F1) is set to
activate at 8:00 a.m., by default, Filter Cycle 2 (F2) will activate at 8:00
p.m. (12 hours later). During 8:00 p.m. to 8:00 a.m., if the spa should call
for heat, the pump and heater will activate to heat the spa under normal
temperature demand. However, when in Sleep Mode, should the spa
call for heat, the pump and heater will be suspended after Filter Cycle
2 (F2) until the activation of Filter Cycle 1 (F1), at 8:00 a.m. to minimize
pump activation during quiet evening hours.
Important: Power-up of the spa starts the F1 sequence. In order for the
sleep mode to work in the evening hours, the spa must be powered up
in the early morning hours. The Sleep Mode will always be active the
6-12 hours between the end of (F2) and the beginning of (F1) depending
on how the filter cycle program is set.
Note: If temperature drops below 80º F (27º C), heater will automatically
activate to prevent spa from freezing.
To activate Sleep Mode feature:
A. Press the MODE ( or ) button until the
TOOLS screen is displayed.
B. Press the (+) button to enter the TOOLS
submenus.
C. Press the MODE ( or ) button until ECON is displayed.
D. Press the (+) button to activate Sleep Mode. Moon & Stars icon will
appear on the screen of the control panel, indicating this feature
has been activated.
To deactivate this feature, simply repeat steps A-C then press the (-)
button.
FILTER CYCLES (NON CIRCULATION PUMP MODELS ONLY)
When the spa is first powered up, the automatic filter cycle will wait
10 minutes before starting. Your spa will automatically turn the first
filter cycle on for 60 minutes on low speed. The second filter cycle will
activate for 30 minutes, 12 hours later. The filter cycle icon, F1 or F2 will
be displayed in the control panel during the filter cycle.
NOTE: The optional FRESHWATER III ozone system only works during
the filter cycle.
To modify the length of either filter cycle:
A. Press the MODE ( or ) button until the
TOOLS menu is displayed.
B. Press the (+) button to enter the TOOLS
submenus.
C. Press the MODE ( or ) button until
FILT1 or FILT2 is displayed.
D. Press the (+) button to enter FILT1 or
FILT2. F1 or F2 icon will flash.
E. Using the (+) or the (-) button, adjust the desired filter cycle time,
from 0 to 6 hours.
The filter cycle will activate the jet pump on low speed for the entire
cycle. When activated, the filter cycle icon 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 for the remaining
filter cycle time. Should the temperature cool down to 1.5 degrees F
(1 degree C) 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 icon and
Jets icon will be on. Once the jet pump has been shut off, a ten minute
tranquil mode begins (Filter & Jet icons are off during tranquil mode
while F1 or F2 remain lit). The Filter and Jet icons will come back on
once the tranquil mode ends if the filter cycle timer is still on.

Spa Care and Maintenance
WINTERIZING YOUR SPA
If you leave the spa unused for a long period of time in severely cold
weather, you should drain the spa and winterize it to avoid accidental
freezing due to a power or equipment failure.
Your HOT SPOT spa is manufactured from the highest quality, most
durable materials available. Even so, the spa care and maintenance
program you develop will ultimately determine how long your spa, and
its individual components, will last. Regular maintenance and following
the advice in this section will help you to protect your investment.
DANGER: Use only Propylene Glycol as your anti-freeze (available
at most RV or marine supply stores). This is non-toxic. Never use an
automobile anti-freeze (Ethylene Glycol) since it is toxic!
DRAIN & REFILL INSTRUCTIONS
IMPORTANT: It is NOT recommended to refill your spa when the
ambient temperature goes below 50° F (10° C).
1. Disconnect the spa from the power supply by tripping both of the
GFCI breakers located in the subpanel. Unplug power cord for 115V
models.
2. Locate the drain valve for the spa (lower front of the spa) and
remove the drain cap. Attach the inlet of a garden hose to the drain
valve (to avoid flooding of the foundation surrounding the spa) and
route the outlet of the hose to an appropriate draining area. Spa
water with a high sanitizer level may harm plants and grass.
3. Open the drain valve by turning the knob. The spa will drain by
gravitational flow.
IMPORTANT: All HOT SPOT spa models will drain almost
completely through the drain valve. Equipment such as the jet
pump and heating system will drain. Any water remaining within the
plumbing or equipment after draining will only need to be removed if
the spa is being winterized.
4. When empty, inspect the spa shell and clean as required. (Follow
the Care of the Exterior instructions.)
5. Close the drain valve by reinstall the drain cap.
6. Install new filter or clean existing with FRESHWATER filter cleaner.
7. Refill the spa through the filter compartment using the CLEAN
SCREEN pre-filter.
IMPORTANT: Refill water temperature must be between 50° - 70°F
to avoid high-limit tripping.
8. Follow the Quick Start-Up instructions on page 5.
COLD WATER REFILL
WARNING: Failure to follow these instructions correctly can lead to
freeze damage not covered by warranty. It is strongly recommended
that you contact your local dealer to perform this service
1. Drain your spa following the Draining Your Spa section in the
owner’s manual. Open waterfall valve.
2. Remove the filter cartridge, clean and store in a dry place.
IMPORTANT: These additional instructions must be utilized
when draining and winterizing your spa in climates where the
temperature falls below 32°F (0°C). A five (5) gallon (19 liters)
PUMP DRAIN PLUG LOCATION

3.
Should it be necessary to drain and refill your spa in temperatures
below 50° F (10° C), the spa may go into a High Limit Protection mode
(causing your spa to stop functioning) if the tap water is below 50° F
(10° C). Blending warm water with the cold tap water so it exceeds 50°
F (10° C) during the refilling process will prevent the spa from going into
the High Limit Protection mode if that is an option for you.
PREVENTION OF FREEZING
Your spa has been designed and engineered for year-round use in
any climate. In some areas, extremely cold temperatures (below
10°F) combined with strong wind, may cause partial freezing of the jet
pump, even though the water inside the spa remains at the selected
temperature. The energy efficiency of the spa may also decrease
during these cold periods, as the heater will cycle more frequently.
As an additional precaution against partial freezing of some of the
components, the equipment compartment can be insulated with an
insulating kit (available from your local dealer). This insulating kit will
also help to maximize the spa’s energy efficiency.
NOTE: When warmer weather returns (approx. 60°-70°F, 15.5º-21ºC),
the insulating kit must be removed to prevent overheating of the jet
pump.

combination (vacuum/blower) wet/dry shop vac
must be used to effectively remove water that is trapped inside the
plumbing lines.
Attach the vacuum hose to the vacuum side of the shop vac.
Vacuum all openings and orifices as follows:
a. Jet openings: start with the jets at the top and move downward
(if suction is coming from another jet, block off the other jet
using a large rag this will help pull out the water that is trapped
deeper inside the main line).
b. Filter suction fittings and filter compartment.
c. Main drain outlet (it may be necessary to cover the drain grate
tightly with a rag when vacuuming the main drain to ensure
water is drawn completely from the internal plumbing system).
Thoroughly dry the spa shell with a clean towel.
Replace the main drain cap.
CAUTION: Use only Propylene Glycol as your anti-freeze. This is
non-toxic. Never use an automobile anti-freeze (Ethylene Glycol)
since it is toxic!
Using a long-extension funnel, pour anti-freeze into all standpipes,
filter suction fittings, jet orifices and water feature orifices. Add
enough anti-freeze to ensure adequate protection – in many
cases, you will see the liquid in the orifice, or coming out of another
location.
7. Close the spa cover and fasten the cover tie downs. Cover the spa
cover with two pieces of plywood to evenly distribute the weight of
snow and ice. Secure a plastic sheet, or tarp, over the spa cover
and plywood.
8. Replace the equipment access door, if removed.
OPENING INSTRUCTIONS:
1. Remove plywood and plastic sheet. Open the spa cover by
unfastening the cover tie downs.
2. Follow the Start-up and Refill Procedures in the Operating
Instructions section of the Owner’s Manual. Do not install filters to
prevent them from exposure to the anti-freeze.
3. As part of this process, superchlorinate the spa water by adding
three teaspoons of chlorine (sodium dichlor) per 250 gallons of spa
water into the filter compartment. This is twice the normal amount
of chlorine needed for superclorination. This extra amount of
chlorine is needed to destroy the anti-freeze.
NOTE: A defoamer may be needed to decrease the amount of foam
caused by the anti-freeze.
4. Drain your spa to ensure removal of anti-freeze. Do not drain water
on grass or plants due to excessive chlorine level.
5. After the spa has completely drained, re-install your filter and follow
the Start-up and Refill Procedures in the Operating Instructions
section of the Owner’s Manual.
IMPORTANT: Always keep spa covered when not in use, whether it is
empty or full.
FILTER SYSTEM
The filter lid on the spa is NOT designed to support heavy weight loads
and should not be used as a seat. In extreme cases, the lid could crack
and break. This occurrence is considered abuse and is not covered
under the warranty.
HOT SPOT spas are equipped with one filter cartridge, sized to meet the
needs of the jet pump system.
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.
WARNING: To reduce the risk of injury to persons using the spa,
DO NOT remove the suction fittings (filter standpipes) located in the filter
compartment and do not sit on the filter lid, in extreme cases the lid
could crack and break. This occurrence is considered abuse and is not
covered under warranty.
SECONDARY SUCTION SCREEN
Located in the foot well of your spa are three secondary suction screens.
The screen is used as a filter to prevent dirt from circulating through the
system.
WARNING: Do not use the spa with the suction screens removed.
Spa Care and Maintenance
FILTER CARTRIDGES
REMOVAL & CLEANING
1. Disconnect the spa from the power supply by turning the power to the
spa OFF.
2. Remove any floating items from within the filter compartment.
3. Turn the filter retainer handle (located on the top of the filter cartridge)
counterclockwise until the retainer can be removed from the filter
standpipe.
4. Remove the filter retainer, cover and cartridge (cover only used on
TEMPO, RELAY & RHYTHM spa models).
SERVICE NOTE: Never remove the filter standpipe when debris is present
in the filter compartment. Debris may find its way into the internal plumbing
which may result in blockage. NEVER REMOVE SUCTION FITTINGS!
5. Always clean the filter using a filter degreaser, such as HOT SPRING

CARE OF THE SPA PILLOWS
The spa pillows 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. The pillows can be conditioned with HOT
SPRING Cover Shield after cleaning. 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 spa use.
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.
Page 25
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.
CARE OF THE EXTERIOR
SPA SHELL
Your HOT SPOT spa has an acrylic 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 (see below for detailed information on cleaning agents).
Always rinse off any spa shell cleaning agent with fresh water.
IMPORTANT:
1. The following products are the ONLY approved cleaning agents
for your HOT SPRING spa shell: plain water, HOT SPRING
FRESHWATER Spa Shine, or Soft Scrub®. The use of alcohol or
any other household cleaner 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, specifically: Simple Green®, Windex® or Spa Mitt.
NEVER USE HARSH CHEMICALS! Damage to the shell by use of
harsh chemicals is not covered under the warranty. Always rinse off
any spa shell cleaning agent with fresh water.
2. Iron and copper in the water can stain the spa shell if allowed to go
unchecked. Ask your HOT SPRING dealer about a Stain and Scale
Inhibitor to use if your spa has a high concentration of dissolved
minerals. (Watkins recommends FRESHWATER Stain & Scale
Defense.)
3. Keep all cleaners out of the reach of children and use care when
applying.
CARE OF THE SPA CABINET
WARNING: The cover is a manual safety cover that meets or
exceeds all prevailing requirements of ASTM 1346-91 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.
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 (one teaspoon dishwashing liquid with two 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.
6. To condition the cover after cleaning, apply a thin film of HOT
SPRING Cover Shield to the vinyl surface and buff to a high luster.
IMPORTANT: 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.
DO:
• Remove snow buildup to avoid breakage of the foam core from the
additional weight of the snow.
• Lock cover lock straps to secure the cover when the spa is not in use.
DON'T:
• Drag or lift the spa cover using either the flaps, or the cover lock straps.
• Walk, stand, or sit on the cover.
• 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.
• Use any lifting mechanisms, chemicals, or cleaners except those
recommended by Watkins Manufacturing Corporation, or its Authorized
Sales and Service Dealer.
COVER LIFTER SYSTEM
The simulated wood cabinet consists of a rigid polymer that combines
the durability of plastic, with the beauty of wood.
Cleaning of simulated wood consists of simply spraying the cabinet with
a mild soap and water solution to remove any stains and residue.
CARE OF THE SPA COVER
To clean and condition the vinyl cover:
Clearance required behind cover when open:

HOW TO OPEN THE VINYL COVER
IMPORTANT: Never attempt to open or remove the vinyl cover by
grasping or pulling on the skirting or cover lock straps. The skirting will
tear, and torn skirting is not covered under the terms of the warranty.
Check for ice build-up around the gas springs and pivot points of the
retractable cover system. Ice buildup may damage system components.
WARNING: The vinyl cover and retractable cover system are not
recommended for use in wind conditions reaching above 25 mph (40 kmh).
IMPORTANT: If your spa is located in an area susceptible to high winds,
additional coverlock straps may be installed to minimize wind damage to
the cover.
1. With the cover lock straps unfastened, place one hand under the
cover skirting, between the spa and cover, to break the cover’s
vacuum seal. Then, fold the front half of the cover over onto the back
half.

2. If no rear access is available, stand to the side of the spa directly
adjacent to the hinge area of the folded cover.
a. For the COVERCRADLE retractable cover systems: Using
both hands, cup one hand under the lower half of the cover
(just above the water) and place the other along the side of
the cover, just above the skirt. Gently push (do not lift) with
both hands towards the opposite rear corner of the cover
(diagonally). As the cover opens, the gas springs will allow the
cover to come to a gentle stop.
b. For the UPRITE retractable cover system: Simply lift the
cover at its center hinge, allowing it to move to the back of the
spa and to rest gently there.
c. For the LIFT ’N GLIDE retractable cover system: Slightly
lift the cover at front of spa, glide (push back until it stops), fold
cover in half and lift cover moving it to the back of the spa.
Insert locking pin into side of lifter to prevent accidental closure.
IMPORTANT: When opening a cover with a retractable cover system, only
use one of these three specific methods. Do not attempt to open the cover
in any other way. Damage caused by improper opening or closing of the
cover is not covered under the terms of the limited warranty.
Spa Care and Maintenance
HOW TO CLOSE THE COVER
1. Standing along side the cover, place one hand on the upper corner
of the cover and gently push forward in the direction of the spa. The
cover will rotate forward to cover half of the spa.
IMPORTANT: For the UPRITE or LIFT ’N GLIDE retractable cover
system, disengage the locking mechanism(s) before pushing the cover
forward.
2. Unfold the cover by lifting the handle located on the top (front) half of
the cover. Allow the unfolded half to fall down onto the spa. The air
pressure created by the cover falling will keep the vinyl skirting from
being trapped between the cover and the spa shell.

Electrical Requirements
The diagram below illustrates how to wire 230 volt permanently
connected spa models:
• An electrical subpanel containing two GFCI breakers is included with
each 230 volt spa. We recommend that this subpanel be used to
supply power to the spa.
• The subpanel requires a 50 amp, single phase, 230 volt, four wire
service (two line, one neutral, one ground). The grounding conductor
must not be less than #10 AWG. Refer to local codes and to NEC 250122 table.
• Mount the subpanel in the vicinity of the spa, but not closer than five
feet away, in accordance with all local codes. (N.E.C. 680-38 to 41-A-3)
Once your spa has been filled with water, turn it on and test all of the
circuit breakers.
IMPORTANT: If both breakers immediately trip, verify that the wires are
correctly connected. Each breaker should be tested prior to each use.
Here’s how:
1. Push the “TEST” button on each GFCI breaker, and observe it
click OFF.
2. Wait 30 seconds, then push the breaker switch to the OFF (down)
position (to ensure that it has completely disengaged), then push
the breaker switch to the ON (up) position. If you don't wait 30
seconds, the spa’s power indicator may continue to blink – try
again.
If any of the GFCI breakers fails to operate in this manner, your spa
may have an electrical malfunction, and you may be at risk of electrical
shock. Turn off all circuits and do not use the spa until the problem has
been corrected by an authorized service agent.
WARNING: Removing, or bypassing any GFCI breaker will result
in an unsafe spa and will void the spa’s warranty.
IMPORTANT: Fill the spa with water before turning on the power.
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 specific spa model completely!
• The TX operates on 115 volts 15 amp 60 Hz.
• The SX operates on 115 volts 20 amp 60 Hz.
Both the SX and TX can also be converted to either 115 volt 30 amp or
230 volt 50 amp.
When the TX or SX spas are connected to 115 volts 15/20 amp, 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 TX, SX spas are connected to 115 volts 30 amp, the
heater will provide approximately 1000 watts of heat when the pump is
operating in LOW or HIGH speed and the thermostat is calling for heat.
When the TX or SX are connected to 230 volts 50 amps, 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.
• The TEMPO, RELAY and RHYTHM models require a dedicated 230
volt power supply.

The Ground Fault Circuit Interrupter (GFCI) is a safety device that is
designed to detect as little as 5 milliamps (±1mA) of electrical current
leakage to ground. Watkins Manufacturing Corporation recommends
that the GFCI be tested prior to each use to ensure it is functioning
correctly. With the spa connected to the power supply, push the "Test"
button. The spa 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, it is an indication of an electrical
malfunction and the possibility of an electric
shock. Disconnect the plug from the receptacle
until the fault has been identified and corrected.
IMPORTANT: Never use the GFCI as a means to
disconnect power to the spa (always unplug it).
If the GFCI is tripped while the spa is plugged in,
and a power outage occurs, when power returns
the GFCI will automatically reset and power will
flow to the spa.
115 VOLT OPERATION (60Hz ONLY)
The spa must be connected to a dedicated 115 volt, 15 or 20 amp,
GFCI protected, grounded circuit. The term “dedicated” means the
electrical circuit is not being used or shared for any other electrical
items (patio lights, appliances, garage circuits, etc.). If the spa
is connected to a non-dedicated circuit, overloading will result in
“nuisance tripping” at the main panel. This requires frequent resetting
of the breaker switch at the house electrical breaker panel and
introduces the possibility of damage or failure of spa equipment.
NEVER CONNECT THE SPA TO AN
EXTENSION CORD!
A pressure wire connector is provided on the exterior surface of the
control box, inside the spa. This is to permit the connection of a ground
bonding wire between this point and any metal equipment, enclosures,
More than 5 feet
the Sub-Panel must be
within sight of the spa
Do Not Exceed 50 Feet
Control Box
reinforced concrete pad, pipe, or conduit within 5 feet of the spa (if
needed to comply with local building code requirements). The bonding
wire must be at least a #10‑AWG solid copper wire.
Bond the spa to all exposed metal equipment or fixtures, handrails, and
concrete pad per N.E.C. Article 680 and all local codes.
INSTALLATION INSTRUCTIONS
All 115 volt spa models come equipped with approximately 15 feet
of useable power cord (this is the maximum length allowed by
Underwriters Laboratory and the National Electric Code). When the spa
is installed, the power cord will come out of the bottom of the equipment
compartment door. For your safety, when the electrician is installing the
single electrical outlet and waterproof cover, the outlet should be no
closer than 5 feet (1.5 meters) and no farther than 10 feet from the spa
[reference National Electrical Code 680-6a(1) and 680-41a].
The Ground Fault Circuit Interrupter (GFCI) is located at the end of the
power cord. This device is for your protection. It is very important to
protect it from rain and other moisture. Test once a month, with the plug
connected to the power supply,
1. Push the “TEST” button on the GFCI breaker. The spa should stop
operating and the GFCI power indicator will go out.
2. Wait 30 seconds, then push the “RESET” button. Power will be
restored to the spa and the GFCI power indicator will turn on.
If the GFCI fails to operate in this manner, your spa may have an
electrical malfunction, and you may be risking electrical shock. Turn off
all circuits and do not use the spa until the problem has been corrected
by an authorized service agent.
WARNING: Removal of the GFCI from the spa’s power cord will
result in an unsafe spa and will void the spa’s warranty.
IMPORTANT: Should you ever find the need to move or relocate your
HOT SPOT spa, it is essential that you understand and apply these
installation requirements. Your HOT SPOT spa has been carefully
engineered to provide maximum safety against electric shock.
Remember, connecting the spa to an improperly wired circuit will
negate many of its safety features.

Electrical Requirements
Service Information
GENERAL INFORMATION
Your HOT SPOT spa has been designed to provide years of troublefree 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
display - - - -. 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.
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.
Service Information
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 (2°C and 49°C); 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
