IMPORTANT SAFETY INFORMATION
READ ALL INSTALLATION INSTRUCTIONS
Warning — Risk of injury: Children, the elderly, and the infirm should not use the spa unless they are supervised at all times. Infants should not be permitted in the spa at water temperatures over 100
°
F (38
°
C).
Spa water temperatures in excess of 104
°
F are not recommended. High water temperatures in excess of 104
°
F
(40
°
C) and prolonged periods of use can raise internal human body temperature excessively and impair the body’s ability to regulate its internal temperature.
Pregnant women and people with heart circulatory problems, or diabetes, should consult their physicians before using the spa at water temperatures over 100
°
F (38
°
C).
Limit your initial use of the spa to 10 –15 minutes. High body temperatures affect people differently; consult your physician about your safety and comfort before using the spa.
If your spa product does not have a thermometer, we recommend that you use a medical (clinical) thermometer for an accurate measurement of spa water temperatures. Other types of thermometers generally available, such as those used for swimming pools, are not sufficiently accurate to determine spa water temperatures.
Extra care should be taken when using the spa and consuming alcoholic beverages. Alcohol, drugs, or certain medications, such as tranquilizers, affect a person’s ability to withstand high temperatures and may produce dangerous effects, including drowning. Persons using medication should consult with a physician before using a spa.
Danger — Risk of injury: Do not remove the suction grille!
It is a safety device and must always be in place on the suction fitting to minimize the potential hazard of hair entanglement or body entrapment.
Keep body, hair, and clothing a minimum of 12 inches away from suction fitting and skimmers at all times when the spa is operating. Hair longer than shoulder length should be secured close to the head, or a bathing cap should be worn.
Do not operate the spa if the suction cover is broken or missing. Contact your Dealer for replacement cover if broken or missing.
The wet surface of the spa is slippery. Use care when entering and exiting.
DANGER — Risk of child drowning: Do not permit children to use this product unless they are closely supervised. Use a locked cover to prevent unattended access.
DANGER — RISK OF ELECTRICAL SHOCK: When installing and operating this electrical equipment, always follow basic safety precautions including the following.
Warning: A wire connector is provided at the electrical cabinet on this spa to connect a minimum No. 8 AWG (8.4 MM 2 ) solid copper conductor between this spa and any metal equipment, metal enclosures of electrical equipment, metal water pipe, or conduit within 5 feet (1.5 m) of the spa.
Do not use electrically connected devices such as television, radio, or stereo speakers, lights, cooking devices, or telephones within 5 feet (1.5 m) of the spa while the spa is being used. Lighting fixtures must not be located directly above or within 5 feet (1.5 m) of the spa. If located within 10 feet (3.0 m) of the spa, they must be on a circuit protected by a Ground
Fault Circuit Interrupter (GFCI).
All fixed metal objects located within 5 feet of the spa, such as fence posts, railings, door frames, greenhouse structures, gutters, etc., must be attached to the bonding bar on the outside of the spa electrical cabinet using #8 solid copper wire.
With #8 solid copper wire, bond the spa to the house
electrical panel or approved local bond.
The spa must be installed so that its components and equipment are accessible and its water drainage system is adequate to drain water away from electrical components.
Refer to Installation Instructions.
CAUTION: Do not turn power ON to the spa unless it is filled with water to the normal water level, which is to the water level indicator mark on the skimmer frame. Activating the spa without sufficient water can damage the circulation pump and may cause a fire.
20 AMP RECEPTACLE
GFCI
Your spa must be installed in a 115VAC, 20 AMP circuit:
1. The spa is supplied with a 15 foot line cord which terminates with an integral GFCI plug. Locate the spa near to a weather-protected outlet, but no closer than 10 feet. DO NOT
USE AN EXTENSION CORD! Using an extension cord is hazardous and will decrease the amount of power to the unit, causing slow heating, poor whirlpool performance, or system malfunction.
2. Replace damaged line cord immediately. Do not bury line cord. Connect only to a properly grounded receptacle.
3. Bring the line cord out from under the skirt. Remove skirt screws as required to gain access. Make sure the line cord does not lie across a walkway or in a heavily traveled area where it may be a safety hazard or become damaged.
4. At initial start-up and before each use thereafter with power ON, push the GFCI test button. The reset button should pop out. Push this button in to reset. If the interrupter fails to operate in this manner, there is a ground current flowing or a device malfunctioning, indicating the possibility of electrical shock. Turn off power and do not use the spa until the
source of the problem has been identified and corrected.

Inspection and Shipping Claims
Check for shipping damage upon receipt of the spa. Jacuzzi Whirlpool Bath is not responsible for damage to the spa sustained during shipping. If damage is evident before unpacking, see instructions regarding shipping claims on the outside of the carton and immediately file a claim with the carrier.
Once the spa has been removed from the carton and before it is permanently installed (see below on this page for unpacking instructions), check the spa completely for damage. Fill the shell with water and operate the system (see
Operating Instructions) to check for leaks that may have resulted from shipping or handling. All Jacuzzi Whirlpool Bath spas are factory tested for proper operation and water tight connections prior to shipping. If leaks or other problems are detected, immediately notify your dealer or Authorized Service Agent, or call 1-510-938-7411 for Warranty Service.
Note: Damage or defects which could have been discovered and repaired prior to installation and which are claimed after final installation of the spa are excluded from our warranty.
Unpacking
1.
Remove the outer carton by cutting the bands and lifting the cover and the sides.
2.
Remove the spa cover which is located on top of the spa. Leave the protective plastic sheet on the spa until installation begins. This sheet can be reused to protect the finish from damage and debris during construction.
3.
Lift the spa from the carton (approximate weight 350 lbs.) and set it in place on the patio, deck, or position of intended use.
4.
If, after having been removed from the carton, the spa must be turned onto its side to move it, make sure the surface of the cart or dolly on which it is placed is large enough to support the entire width of the spa, including the rim and base of the skirt. The skirt is not designed to support the product weight and could be damaged if allowed to do so. For further protection of the skirt, make sure the surface of the cart or dolly is padded. Do not allow the spa to rest on the equipment door side.
See illustration at lower right.
5.
Before installation begins, remove the owner's packet from the accessory package. This package contains the Warranty Card and the Owner's Manual. Record the spa serial number on the inside front cover of this manual and on the warranty card. (See illustration on page 2 for location of the serial number.)
6.
Place the filter cartridge in a dry place for later use.
Important: Read all instructions in the Owner’s Manual before beginning installation.

INSTALLATION
Important: Read complete instructions before beginning installation.
Positioning Your Spa
Because your spa is portable, you can install it just about anywhere you wish—on a deck, patio, or even indoors.
Be sure to position it above ground in an area with good drainage and on a level, continuous surface which can support the weight of the spa when filled with water and people; this weight is approximately 2365 lbs (76 pounds per square foot). You must also provide access to the spa’s equipment pack for service and general maintenance.
Electrical Requirements
Your spa, as it comes from the factory, requires a 115 VAC 20 AMP electrical outlet and must be in a grounded separate circuit having no other appliance connected in that circuit. If you do not have a 115 VAC 20 AMP circuit, call a qualified electrician to install the necessary wiring. Inadequately sized wiring or locating the outlet too far from the main service panel may cause a voltage drop which might cause the unit to malfunction and cause permanent damage to the spa’s electrical system. The outlet must also have a ground wire in order to take advantage of the designed-in safety features of the spa.
A bond wire must also be used. Bond according to step 5 below.
Caution: Without proper grounding and bonding, a system malfunction may cause fatal shock.
Electrical Precautions
1.
The spa is supplied with a 15 ft. line cord which terminates with an integral Ground Fault Circuit Interrupter (GFCI); locate the spa near a weather-protected outlet, but no closer than 10 ft. from the spa. DO NOT
USE AN EXTENSION CORD! Using an extension cord is hazardous and will decrease the amount of power to the unit, causing slow heating, poor whirlpool performance, or system malfunction.
2.
Bring the line cord out from under the skirt at one of the corners, lifting the spa slightly to allow the GFCI to pass through. Make sure the line cord does not lie across a walkway or in a heavily traveled area where it may be a safety hazard or become damaged. To prevent the skirt from resting on the cord, cut a small notch in the skirt to allow the cord to pass through, if necessary.
3.
Do not locate lighting fixtures directly above the spa. If lighting is located within 5 ft. of the spa, it must be on a circuit protected by a GFCI.
CAUTION
Do not plug in the spa unless it is filled with water to the normal water level, which is approx. 6" below the spa rim.
If the spa’s motor/pump is actuated when there is not sufficient water in the unit, the circulation pump could be irreparably damaged. Not heeding this caution will nullify the warranty. In addition to damaging the unit, operating the unit with insufficient water could cause a fire.
4.
Do not use electrically connected devices, such as television, radio, telephones, stereo speakers, lights or cooking devices within 5 ft. of the spa while the spa is being used.
5.
All fixed metal objects located within 5 ft. of the spa, such as fence posts, railings, door frames, greenhouse structures, gutters, etc., must be attached to the bonding bar on the outside of the spa System Control
Module using #8 solid copper wire. With #8 solid copper wire, bond the spa to the house electrical panel or approved local bond. Bonding lugs are available at your local electrical supply store. (See illustration on page 5 for bond bar location.)
6.
An approved ground may be an 8 ft. long ground rod, a plate electrode, or a buried metal water pipe with at least 10 ft. of buried pipe. Check your local building code for requirements.
WARNING!
The continuous service ground wire is located in the line cord supplied. Do not modify this cord in any way!
Tampering with the ground wire or using an adaptor which would make the built-in grounding device and
GFCI ineffective would cause electrical shock. Such modification also nullifies the warranty.

INSTALLATION
Outdoor Installation
If you install the spa outdoors, we recommend that you provide a concrete pad for it to rest on. To do this, construct forms for a 7' x 6' x 4" thick level pad. Install a #10 gauge wire mesh 6" x 6" steel reinforced grid. Attach a #8 solid copper wire to the grid with a water pipe ground clamp. This wire should be long enough to reach the bond bar on the spa System Control Module ( a minimum of 36"), but should not be located under the base of the spa. Then pour the concrete pad.
Drainage
Whether you install your spa indoors or outdoors, you can drain it by attaching a garden hose to the drain valve located on the suction tee of the spa. Simply run the hose to the house sewer line or drain field and open the hose bibb.
Make sure the area surrounding the spa has good drainage to keep water from collecting at the base of the spa—especially near the equipment area. If drainage is poor, install a drain line and/or gravel drain field. (See illustration below.)
Indoor Installation
Water which splashes on the floor during use of the spa may cause a walking hazard and/or structural damage unless good drainage is provided and proper waterproof building materials are used in the area surrounding and beneath the spa. Also take into consideration the high room humidity caused by high spa water temperatures. Providing natural or forced ventilation of the room will help maintain comfort and minimize moisture damage to the building. Jacuzzi Whirlpool Bath is not responsible for damages resulting from excess moisture or water spillage.
Consult an architect or engineer for aid in designing your indoor installation.

Operating Instructions
Now that your spa is installed, you are ready to take advantage of its unique design features—especially the patented hydromassage performance. Besides being a beautiful addition to your indoor decor or outdoor landscaping, your Jacuzzi
Whirlpool Bath spa will provide you with the ultimate in spa pleasure.
Basic Control Set-Up
The control setup on your spa is designed to give you fingertip control of the heater, air induction, and whirlpool/filter pump and blower systems of your unit from inside or outside your spa. Follow the basic control setup described on page 9 to familiarize yourself with the various functions of the control panels located on the top of the spa.
WARNING: Do not turn on power to the spa unless it is filled with water to the normal water level, which is 6" below the spa rim. If the spa’s motor/pump is actuated when there is not sufficient water in the unit, the circulation pump could be irreparably damaged. Not heeding this caution will nullify the warranty. In addition to damaging the unit, operating the spa with insufficient water could cause a fire. If an optional timer is used, be sure it is disconnected when there is insufficient water in the spa.
Initial Instructions
• Using a garden hose, fill the spa with water to the waterline at 6" below the spa rim.
• Lift up the skirt door.
• At the house service panel, turn ON the circuit breaker or a switch that controls the electrical service to your spa. Plug the line cord into a 115VAC 20 AMP receptacle. (Make sure there is no other appliance on this circuit.)
• Your spa is provided with a Ground Fault Circuit
Interrupter (GFCI). At initial start-up and at least once a month thereafter, with power on, push the test button located on the spa line GFCI. The reset button should pop out. Push this button in to reset. If the interrupter fails to operate in this manner, there is a ground current flowing or a device malfunctioning, indicating the possibility of electric shock. Turn OFF power and do not use the spa until the source of the problem has been identified and corrected.
• Locate the HIGH TEMPERATURE SAFETY SWITCH, which is a button on the end of the heater. Push this button to be sure it is in the reset mode. The purpose of this switch is to turn off the heater in case of excessive heat in the heater housing. If, for some reason, the switch is tripped, the reset button must be pushed in the heater to operate again after the water has cooled to 90
°

OPERATION
Function Selector Switch
To ensure your safety and allow easy operation, your spa is equipped with an air-activated function selector switch located on the side panel of the redwood skirt, near the front corner of the spa. This push-button switch selects the following four functions in the continuous sequence indicated:
1. OFF
2. WHIRLPOOL
3. HEATER/FILTER
4. FILTER ONLY
(The next selection is OFF again.)
You know which function you are selecting when the whirlpool system is activated. Use that function as a reference to indicate your location in the function sequence, since that function is the most obvious when operating.
For best performance, pause a second or two between push-button selections.
Setting the Thermostat
Turn on the heater by selecting the HEATER/FILTER mode on the selector switch. You can verify that the spa's heater is operating by looking through the small factorydrilled hole located in the door panel of the spa and checking that the red indictor light is illuminated.
The thermostat adjustment knob is located on the front of the heater. To set the thermostat, turn the knob to the desired temperature. If the water temperature reaches a level higher than you wish, turn the thermostat knob back to a lower setting. The spa's water temperature will stabilize after a while and fall a few degrees before the heater turns on again. When the water temperature reaches the temperature set on the thermostat, the heater and motor/pump will turn off automatically.
MODEL Z100 SPA
(SHOWN WITH HEATER CONTROLS EXPOSED)
The water temperature will rise at a rate of about 2 0 F per hour, depending on the temperature of the air surrounding the spa. This rate requires a waiting period before using the spa, the length of which is determined by the temperature of the water before turning on the heater. For example, if the water in the spa is kept at about 70
°
F when the spa is not in use and the water temperature at which you plan to use the spa is 100
°
F, then it will take about 15 hours to heat up to the desired 100
°
F temperature.
Once you have determined the desired setting on the thermostat knob, it is not necessary to change or readjust it again during normal operation unless you decide on a different setting.
The spa cover provided for your spa will help control heat loss from the water surface and thereby reduce energy consumption. You can improve the spa’s heat retention by keeping the spa cover in place on the spa while heating the water.
Notes on Determining Water Temperature:
As spa products generally perform in a narrow range of operating temperatures, we recommend that you use a medical (clinical) thermometer for an accurate measurement of spa water temperature. Other types of thermometers generally available, such as those used for swimming pools, are not sufficiently accurate to determine spa water temperatures. Take water temperature readings in the
HEATER/FILTER mode when the heater has just turned off; the indicator lamp on the heater housing will turn off at this time.

Whirlpool System
You can enjoy the spa with or without activating the whirlpool. Either way, bathing in your spa can be pleasurable, as well as therapeutic. After a busy, stressful day, you can look forward to soaking in your spa in still water with no turbulence and warm water to soothe and relax you.
For a more invigorating spa experience, you can take advantage of the built-in whirlpool system. To do this, select the
WHIRLPOOL mode. Sit or recline in the spa so you are comfortable. Since the four whirlpool jets are adjustable, you can direct a jet toward any location of your body, particularly toward any area that feels tense or stiff. The warmth of the water and the stimulating water flow from the jet will pleasantly increase circulation to that area.
HIGH VOLUME ADJUSTABLE WHIRLPOOL JET Silent Air Induction
The intensity of the whirlpool action is determined by how much air is inducted into the water. You can control the air flow by adjusting the two air induction control knobs located on the control panel. For maximum air induction, turn each control knob fully counter clockwise to the largest dot. For fewer air bubbles, decrease the amount of air induction by turning the control knob clockwise. When the knobs are turned to the smallest dot, only water is being circulated.

Special Suction Features
A special feature has been designed into the pump suction of the spa that automatically reduces the amount of suction power if the suction fitting is blocked by an object or by someone using the spa. The bather will know that such a situation is happening by an additional "gulping" sound in the system. When this does happen, remove the object, and normal water flow will be restored automatically.
Note: Refer to Safety Information on the inside front cover of this Manual.

Filtration
When you are ready to leave the spa, select the HEATER/
FILTER mode to maintain the desired water quality and temperature. If you want to filter the water without heating, select the FILTER ONLY mode.
The filter pump should be run at least one (1) hour per day to allow filtration of the water and maintain water clarity.
Select the FILTER mode and run the filter each day. If the
HEATER/FILTER mode is selected and the spa heater operates at least one hour per day, it will be filtering at the same time, and it will not be necessary to turn the filter pump on separately.

MAINTENANCE
Water Quality and Water Chemistry
Maintaining water quality and the proper water chemistry in your spa is extremely important and should be a regular part of your spa maintenance program, as a neglected spa can be a breeding place for dangerous bacteria.
The water quality of your spa is maintained by a combination of filtration and chemistry. The spa’s integral filter system helps maintain the water cleanliness and clarity by trapping most solid materials such as hair, and other debris resulting from normal use. The most important part of maintaining water chemistry, however, is keeping the proper level of disinfectant in the water at all times. This is accomplished by adding chlorine or bromine to the water, which will control particles too small to be trapped by the filter, such as bacteria and algae, and will oxidize any organic materials. Follow instructions provided here and with water quality products for the health and safety of spa users, and to make your spa bathing as enjoyable as possible.
Filtration
The filtration system of your spa will keep your water clear and clean if used properly. The filter cartridge elements will trap most solid materials and debris in the water. However, the presence of materials such as body oils or other particles which are too small to be captured in the filters may cause various undesirable water quality conditions. These conditions can be corrected with the use of spa treatment chemicals available from your Jacuzzi
Whirlpool Bath dealer. Such conditions include the following:
Foaming: A defoamer is available to minimize foaming of the water. This condition is usually caused by the addition of soaps or oils, or other fatty substances to the spa water.
The interaction of these with hot water, especially at high pH (more alkaline), will cause the water to foam. (Refer to
Water Quality Definitions on page 11.)
Water Chemistry
You can ensure better water chemistry by testing your spa water every day and adjusting the chemical balance frequently. Obtain a water quality test kit, designed especially for spas, from your Jacuzzi Whirlpool Bath dealer.
The test kit must be of a type that allows you to test for the disinfectant (chlorine) level, pH, and total alkalinity. Ensure that the chemicals used in your spa are especially for spa use, and not for swimming pools, as water quality maintenance of spas and of swimming pools is very different.
Set up a daily program at first to check the disinfectant level, pH, and total alkalinity of the water. Familiarize yourself with the amount of chemicals to add and determine how often to make chemical adjustments during normal use. Remember that the more heavily the spa is used, the more often you should check the water chemistry.
When adding chemicals, always run the filter system to ensure complete dilution with the water. Do not add chemicals directly into the skimmer.
Oil Film or Cloudy Water: Add clarifier to congeal oil film on the water surface into globules sufficiently large to be trapped by the system’s filter. Cloudiness is caused by particles that are too small to be trapped in the filter, and is also due to the presence of human body oils, lotions, and cosmetics. During normal use, these materials can accumulate on the filter element and clog its pores. The addition of clarifier will make the water clearer, but clogged filters must be cleaned as prescribed under the section entitled
Filter Maintenance in this manual (page 12).
Hard Water: Add a demineralizer to break down or deionize mineral particles present in the spa water.
Follow the Filter Maintenance procedure described in this manual (page 12) to ensure optimum performance of your spa’s filtration system.
10
MAINTENANCE
Water Chemistry (Continued)
Disinfecting
When filling the spa for the first time, follow the purge/ sanitizing instructions in the Equipment Set-Up procedure of the Installation Instructions (page 6).
Add a disinfectant to the water on a regular basis to help control the amount of bacteria, algae, and organic materials. Such bacterial contaminants, if not controlled, could cause skin rashes or other physical problems. To disinfect the spa for normal use, first establish the amount of chlorine or bromine to add and determine how often you need to add these.
We recommend that you maintain a free chlorine level of 2.0–5.0 ppm at all times except when you must exceed that during the initial purge/sanitizing procedure or during superchlorination (refer to Water Quality Definitions below). Superchlorinate your spa every two weeks during periods of heavy use. If using sodium dichlor, add one heaping tablespoon for each 150 gallons of spa water.
Scrub the spa surfaces with this solution to remove oily deposits. This will ensure that bacteria or algae which are resistant to the normal disinfectant level are killed. After adding the disinfectant, run the filter system and allow the free chlorine level to return to the 2.0 to 5.0 ppm range before using the spa again. Do not install cover until the disinfectant level is back to normal. High concentrations of chlorine or bromine will damage metallic plated finishes if the cover is in place.
Balancing pH
For good hygiene and equipment longevity, maintain the pH of your spa water at the level recommended in the instructions. pH is the measure that determines if the spa water is too acidic. Low pH indicates the water is too acidic.
High pH indicates the water is too alkaline or basic. The ideal range for spa water is 7.2 to 7.6 pH. For excessive acidity (below 7.2 pH) add soda ash or sodium bicarbonate to the spa water. For excessive alkalinity (above 7.6 pH) add dry acid to the spa water.
Caution: Refer to the spa chemical manufacturer’s instructions for the initial amount of chemicals to add for the gallonage of your spa. Low pH can cause equipment damage, as acid water will dissolve metals, and high pH can cause scale or calcium deposits to build up in the system or on the shell. After adding chemicals, run the filter system for at least 30 minutes before testing water quality again for accurate readings.
Balancing Total Alkalinity
Total alkalinity is the measure of base materials in the water. The recommended range for total alkalinity is between 80 ppm and 150 ppm. If the chemistry of the water is not within this range, you will have difficulty adjusting your pH level, which will affect your adjustments for the proper amount of free available chlorine. If the alkalinity of your spa water is high, it is advisable to drain the water from the spa and begin the balancing process over again. Purge and sanitize your spa (according to instructions in Equipment Set-Up section of the Installation Instructions) and clean the spa surfaces thoroughly before refilling with fresh water. Then reestablish proper water chemistry. If the spa is used heavily, change the water at least every month.
WATER QUALITY DEFINITIONS
pH: A chemical term used to express relative acidity or alkalinity in numeric values with 7.0 usually regarded as neutral, and for purposes of this manual, indicating pure water. From 7 to 0 indicates increasing acidity, and 7 to 14 indicates alkalinity.
PPM: Parts per million.
Free Chlorine: Chlorine that has not combined with other chemicals and that is available to destroy bacteria in the spa water.
Trichlor: A form of chlorine used in pool or spa water treatment; usually supplied in tablet form. Not recommended because of its higher acidic nature and slow dissolving action. Prolonged contact with the spa shell may bleach or permanently mark the shell.
Sodium dichlor: The type of chlorine recommended for spa use, as it is available in fast dissolving granular form. It is neither excessively acidic nor alkaline in character and does not readily dissipate in higher water temperatures.
Calcium Hypochlorite: A granular chlorine product that is inexpensive and effective but not recommended because it often tends to form calcium deposits on heater parts and plumbing fittings and leaves an unattractive film on the spa at the water line.
Sodium Hypochlorite: A liquid chlorine product that is inexpensive and effective but not recommended because the liquid is readily spilled onto the spa or a surrounding area, causing permanent damage.
Total Alkalinity: The measure of the amount of alkaline materials (such as carbonates, bicarbonates and hydroxides) in the water. High alkalinity inhibits the effectiveness of chemicals to change the pH. If the alkalinity of your spa water is high (above 150 ppm), it is advisable to drain the water from the spa and begin the balancing process over again. Low total alkalinity (below 60 ppm) could be corrosive and damage your spa system.
Superchlorination: (Also referred to as shock treatment.) The addition of an above-normal level of disinfectant to kill any bacteria or algae that might have become resistant to normal levels of disinfectant.

MAINTENANCE
Water Level/Drain
The water level in the spa must be maintained at its normal level. Evaporation and splashing will cause the water level to drop.
When concentrations of impurities from evaporation, water quality chemicals, body oils, perfumes, dirty feet, wind, etc., accumulate in the spa and cannot be filtered out, it is necessary to drain your spa and refill it with fresh water.
This should be done every 2 months or more often depending on the amount of use.
To drain the spa, turn all controls to OFF, then turn off circuit breakers at the main electrical panel. Connect a garden hose to the hose bibb on the suction plumbing. Turn the handle and drain the spa.
NORMAL WATER LEVEL
6"
Filter Maintenance
The filter should be checked periodically. In normal use, check the filter at least once a month. Keep the filter clean; an obstructed filter reduces water quality and inhibits proper system performance.
To clean the filter, first drain the water from the spa until the water level is just below the cap of the filter housing.
Then drain the filter housing by loosening the drain plug at the bottom of the housing. Turn the locking ring to the left until it snaps loose. Grasp the filter housing firmly, and rocking it gently side to side, pull the housing downward until it is free of the cap. To remove the filter cartridge, turn the housing upside down. Clean the filter by separating the folds of the filter and spraying with fresh water from a garden hose; then reinstall the cartridge in the housing and replace the housing, reversing the above procedure. A tube of silicone lubricant is provided with the product. Apply a film of lubricant to the rubber o-ring on the filter housing cap when necessary.
Oils will coat the filter, eventually reducing the flow. To remove such materials, soak the cartridge in a plastic pail containing a commercial filter cleaning solution (available from your dealer or most pool supply stores). Follow the manufacturer’s instructions for use. Another method is to soak the filter cartridge in a plastic pail containing a mild solution of trisodium phosphate (TSP) and water. An hour of soaking time is usually required to break down oil coatings from the cartridge. Use a stronger solution of TSP and water to remove algae. Most hardware or paint stores stock TSP. Use the same method of cleaning when the cartridge becomes plugged with clay or vegetation. Replacement cartridges are available through your Jacuzzi
Whirlpool Bath dealer.
After draining the spa, clean the spa shell and the suction strainer and refill the spa with fresh water; then check the pH level and maintain water quality.
WARNING: Remove the skimmer cover and suction strainers only for cleaning. The strainer is a safety device and must be in place over the suction fitting to minimize potential hazard of hair and body entrapment.

(PULL DOWNWARD
TO REMOVE)
There are two suction strainers on your spa. One is located in the foot well area of the spa; the other is located under the skimmer cover, which can be pulled off easily for access to the suction strainer. The strainers should be checked at least once a week for collected debris, such as leaves, hair, etc., and cleaned as necessary. Remove the center screw with a
Phillips screwdriver and clean each strainer by flushing with water from a hose.
WARNING: Be sure to replace the suction strainer immediately after cleaning. It is a safety device and must be in place over the suction fitting at all times!

MAINTENANCE
Automatic Filtration/Maintenance
If you plan to be away, you should maintain minimum water quality by running the filter system. To do this, select the
FILTER mode. In this mode, the filter system will run continuously until you return, unless you use the optional timer.
If you will be away for an extended period, however, we recommend that you drain the spa (following the procedure described under Winterizing below), as long periods without maintenance of water quality could be detrimental to the spa.
Another means of maintaining minimum water quality while away for less than two weeks is to follow the procedure outlined for winterizing your spa in a warm climate. Note: We do not recommend using this procedure if you are absent during the summer, when algae buildup is most likely.
Always keep your spa covered when not in use to reduce heat loss and evaporation and to prevent debris from falling in.
Winterizing
In a climate where winter temperatures are below freezing, follow this procedure when the spa will NOT be used:
1.
Select the OFF mode.
2.
Turn off power to the unit at the house circuit breaker.
3.
Drain the spa.
4.
Drain the spa completely by attaching a garden hose to the hose bibb on the suction plumbing. Then remove the hose and leave the hose bibb open to completely drain the spa. Close the hose bibb.
5.
Remove the filter cartridge, clean it, and store it dry.
6.
Keep water and debris out by covering with the spa cover provided.
7.
Before using the spa again, review the Operating
Instructions.
CAUTION: Not winterizing will cause irreversible damage (at freezing temperatures) to the pump and/or plumbing lines.
In a warm climate where there are occasional freezing temperatures, follow this procedure:
1.
Select the HTR/FLTR mode.
2.
Set the thermostat to its minimum temperature
(45-50 0 F.) by turning the HEATER KNOB all the way counterclockwise.
3.
Maintain the prescribed chemical balance. (See Water
Quality section, pages 10–11.)
4.
Keep the spa covered.
Spa Cover
The spa cover which has been provided with your spa has been designed to help reduce energy costs by minimizing heat loss and evaporations from your spa. In addition, the attractive spa cover is as effective means of preventing debris such as leaves and dirt from entering your spa when it is not in use. Clean accumulations of dust and dirt off the spa cover using a mild liquid detergent solution.
CAUTION: The spa cover is not designed to support any weight. Therefore, as a safety precaution and to preserve the life of your cover, you must not sit, or lie on it; nor should you place objects of any kind on top of it.
Jacuzzi Whirlpool Bath does not guarantee or warrant this cover. Refer to spa cover manufacturer's information provided with the cover.

Factory Installed Redwood Skirt
Your spa is supplied with a factory-installed redwood skirt which completely surrounds the spa. The door can be opened for routine maintenance.
CAUTION: Do not attempt to lift the redwood skirt door panel higher than the top of the spa. Doing so may cause damage to the skirt door.
The skirt is made of kiln-dried redwood and can be left natural to weather or you may choose to apply a stain or clear finish. Consult your local paint dealer for the appropriate product. Do not use oil-based stains or sealers.
It may become necessary to remove one or more of the skirt panels for major service access, but all the panels must be securely in place during use of the spa.
To detach any of the panels or the short door rear panel on the opposite side of the spa, remove all screws from the panel being detached. Then pull the bottom of the panel downward and outward from the bottom of the panel.
To detach either of the long side panels, it is first necessary to remove one short panel (door or rear). Remove the screws from the panel; then slide the panel horizontally and pull downward. The panels can be reattached to the spa by reversing this procedure.
MAINTENANCE
Cleaning Your Spa
Your spa shell consists of two layers of plastic materials. Its smooth top surface of acrylic is tough and durable and contains concentrated color. This is supported by a substantial thickness of fiberglass-reinforced polyester resin. A catalyst causes a chemical reaction during manufacture that bonds these layers permanently into a hard, strong material. With a minimum amount of care and cleaning, your whirlpool spa will look new for years.
To clean your spa, simply use a mild, nonabrasive liquid detergent, or commercially prepared spa cleaner.
Do not use abrasive cleaners. You can protect and restore the gloss to a dulled surface by applying Meguiar’s
#10 Mirror Glaze, which is a product specifically designed for use on acrylic finishes. If Meguiar’s is not available, an acrylic polish of equal quality or automotive paste wax will do.
Use a spa cleaner for residue buildup at the water level of the spa surface. This may be applied to the acrylic surface with a soft cloth and wiped clean. Use sparingly in small amounts to avoid contaminating the spa water. If heavily soiled, it may be advisable to lower the water level
2–3 inches before cleaning, then refill to normal level.
Repairs to the Acrylic
Minor scratches which do not penetrate the color finish
(acrylic) can be removed with 600-grit wet/dry sandpaper.
Restore the glossy finish with Meguiar’s #10 Mirror Glaze.
If that is not available, use automotive rubbing compound followed by an application of automotive paste wax.
Major scratches or gouges which penetrate the acrylic surface will require refinishing. Ask your spa dealer for special instructions.

IMPORTANT
The Model Z100 Portable Whirlpool spa requires a separate 115 VAC 20 AMP electrical supply. If the wiring for the circuit in which your spa is connected is not sized properly for 20 AMP, or if the outlet used is too distant for the main service panel, there may be a considerable voltage drop. Such a voltage drop would not only cause the unit to malfunction, but it may also cause permanent damage to the spa's electrical system.
Before operation your spa, therefore, we recommend that you test the spa's intended electrical supply circuit for sufficient voltage. To do this, you will need an AC voltage meter and a small electric appliance rated at 1200 (minimum)–1600
(maximum) watts. A hair dryer or toaster will do. Plug the appliance into one receptacle and turn it on; take a voltage meter reading from the adjacent receptacle. If the voltage is measured at 115 VAC (a voltage drop of 5%, or if there is less than the 105V minimum operating voltage at the receptacle, the electrical supply is insufficient. The minimum voltage must be maintained during spa operation.
If your test reveals insufficient electrical supply, several solutions are possible. First, you could have your electrical supply upgraded and provide a dedicated, properly wired circuit with 20 AMP capability to be used for the spa only. Second, you can install a transformer which would boost your existing power supply. We recommend that you seek the advice and service of a qualified electrician who can determine your particular electrical needs for installation of your spa.
