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
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.

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.

The Model Z100 Whirlpool Spa
Installation Instructions
The Model Z100 is a portable whirlpool spa that comes
complete with integrated electric heater, filter, skimmer,
and whirlpool system. The 64" X 70" spa includes a factory
installed redwood shirt and a spa cover to protect the spa
from debris and reduce heat loss. Foam insulation is
factory-installed around the spa shell to ensure better heat
retention.
The Model Z100 features two-level seating for four
people. Four strategically located jets are directionally
adjustable and provide superb hydromassage performance.
Two knobs conveniently located on the rim of the spa give
you control over the Silent Air Induction system. A four
position switch controls heating and filtration, activates the
whirlpool, and turns the unit off. The water temperature is
regulated by an adjustable thermostat located on the
heater assembly. Made of sun- and weather-resistant
acrylic/FRP, the spa shell will retain its lustrous color for
years.
Compact and portable, the spa is easy to install. It
requires a 115 VAC 20 AMP grounded, separate circuit and
is equipped with a Ground Fault Circuit Interrupter (GFCI)
incorporated onto the cord. The equipment is mounted
within the perimeter of the shell.

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.

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.

OPERATION
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.
• 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.
• Lift up the skirt door.
• 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°F.
• Close the skirt door.

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.

The water temperature will rise at a rate of about 2
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.
F per
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.

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.

OPERA TION
Normal Operation
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
TOTAL WHIRLPOOL EFFECT
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.
DECREASE AIR FLOW
(CLOCKWISE)
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.)
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).
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.
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.

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.
11
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"
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.
If heavy rains raise the spa water level, drain the spa to
its normal level, which is 6" below the spa rim.
A spa cover (available as an option), when in place over
the spa, will help reduce evaporation and control the
amount of debris entering the spa when the spa is not
occupied. In addition, its use will reduce energy
consumption.
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.

Suction Strainer Maintenance
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 freez-
ing temperatures, follow this procedure:
1. Select the HTR/FLTR mode.
2. Set the thermostat to its minimum temperature
3. Maintain the prescribed chemical balance. (See Water
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.

MAINTENANCE
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.
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.

IMPORT ANT
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.
