IMPORTANT SAFETY INFORMATION
READ ALL INSTALLATION INSTRUCTIONS
Jacuzzi Whirlpool Bath does not recommend spa water
temperatures in excess of 104°F. Water temperatures in
excess of 104°F and prolonged periods of use can raise the
internal human body temperature excessively and impair
the body’s ability to regulate its internal temperature. 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.
The elderly, the infirm, and children should not use the spa
unattended. Infants should not be permitted in the spa at
water temperatures over 100°F. Pregnant women and
people with heart conditions should consult their physicians
before using the spa at water temperatures over 100°F.
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.
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 remove the suction grilles! They are safety devices
and must always be in place on the suction fitting to
minimize the potential hazard of hair entanglement or body
entrapment.
not sit, stand or lie on it.
The spa must be installed with adequate access and water
drainage system. (See Installation Instructions.)
When using the electrical equipment, basic safety
precautions should always be followed:
This unit is equipped with a ground fault circuit interrupter
(GFCI) located at the end of the line cord. Check at least
once a month to be sure this is operational. (The procedure
for testing is described on page 7 of this manual.)
Do not use electrically connected devices such as television, radio, or stereo speakers, lights, cooking devices, or
telephones within 5 feet of the spa while the spa is being
used. Lighting fixtures must not be located directly above
or within 5 feet of the spa. If located within 10 feet of the spa,
they must be on a circuit protected by a GFCI.
Do not apply power 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
when there is an insufficient amount of water can damage
the circulation pump and may cause a fire.
Read manufacturer’s safety information provided with all
optional equipment.
The wet surface of the spa is slippery. Use care when
entering and exiting.
While the optional spa cover is rigid, it is not designed to
support any weight. Therefore, as a safety precaution, do
Save These Instructions for Future Use.

INST ALLATION
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 which 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 Jacuzzi Whirlpool Bath dealer or Authorized Service Agent, or call Jacuzzi Whirlpool Bath,
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. Leave the remaining
plastic sheet attached to the top of the spa shell to
keep the shell clean and free from debris during
installation.
2.
Remove the rigid spa cover which is located on top of
the spa. Lift the spa from the carton (approximate
weight 350 lbs.) and set it in place on the patio, deck,
or position of intended use.
Before installation begins, remove the owner's
4.
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 1 for the serial
number location.)
5.
Place the filter cartridge in a dry place for later use.
3.
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
ment door side. See illustration at lower right.

Important: Read complete instructions before beginning installation.
Positioning Your Spa
Because your spa is portable, you can locate 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 , water and people; this weight is approximately 1965 lbs. You must also provide access to the spa’s equipment
for service and general maintenance.
Electrical Requirements
Your Alexa, 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, a qualified electrician
should be called in to install the necessary wiring. Inadequately sized wiring may cause a voltage drop which might cause
the unit to malfunction and bring about permanent damage to the spa’s electrical system. The circuit 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 procedure described on the next page.
Caution: Without proper grounding and bonding, a system malfunction may cause fatal shock.
Electrical Precaution
1. The spa is supplied with a 15 ft. line cord which terminates
with an integral Ground Fault Circuit Interrupter (GFCI)
plug. Locate the spa near enough to a weather protected
outlet, but no closer than 10 ft. DO NOT USE AN EXTENSION CORD! Using as 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 through either of
the notches in the pan - right side or center/back. 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.
3. Do not locate lighting fixtures directly above the spa. If
lighting is located within 5 feet of the spa, it must be on a
circuit protected by a GFCI (Ground Fault Circuit Interrupter).

4. Do not use electrically connected devices, such as television, radio, telephones, stereo speakers, light or cooking
devices within 5 ft. of the spa when 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 locate 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
would also nullify the warranty.
CAUTION
Do not apply electrical power to the spa unless it is filled with water to the normal water level, which is approx. 6" below
the spa rim (see location of water level indicator on face of skimmer on page 6). If the spa’s motor/pumps are 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.

INSTALLATION
Outdoor Installations
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 ground clamp. This wire should be long
enough to reach the bond bar on the spa System Control
Module (min. 36"), but should not be located under the base of
the spa. Then pour the concrete pad.
Optional Timer Installation
It is possible to install a timer if you wish to control the on/off
function of your spa and thus automatically filter and heat your
spa water at a specific time of day(s). Such a timer must be an
outdoor type (although it can also be used indoors) having a
rating of 20 AMPS for 1HP with the required 20 AMP receptacle
and plug configuration. This kind of timer is typically plugged
into the house receptacle, and the spa line cord is plugged into
the timer. Several appropriate timers are available, including
one made by Intermatic, Model #P171-32, which you can buy
from your Jacuzzi Whirlpool Bath Dealer (JWB PN 5400000).
Follow the timer manufacturer's instructions for installation
and operation.
Drainage
Whether you install your spa indoors or outdoors, you can
drain it completely by attaching a garden hose to the hose bibb
(drain valve) located on the suction plumbing 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 Installations
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. Take
into consideration also, the high room humidity which will exist
due to 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.

Basic Control Set-Up
The control set-up 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 set-up described on page 9 to
familiarize yourself with the several functions of the control panels.
CAUTION
Do not turn on power to the spa unless it is filled with water to the normal water level, which is approximately 6"
below the spa rim (See water level mark on skimmer). If the spa’s motor/pump is actuated when there is not sufficient
water in the unit, the circulation pump and heater 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.
Using a garden hose, fill the spa with water to the water
line at water level mark on skimmer.
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 that circuit.)
Your spa is provided with a Ground Fault Circuit Interrupter (GFCI) on the line cord. At initial start-up (and at
least once a month thereafter), with power on, push the
test button located on the 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 breakdown has been
identified and corrected.
DETAIL OF GFCI
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.

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 control panel at the rim, near the front
corner of the spa. This push-button switch selects the
following four functions in the continuous sequence indicated:
1. OFF
2. JETS
3. HEATER/FILTER
4. FILTER ONLY
(The next selection is OFF again.)
You know which function your 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
opening the skirt door, and checking that the red indicator
light is illuminated on the back of the heater housing.
The heater adjustment knob is located on the control
panel. To set the thermostat, rotate the knob to the desired
temperature. If the water temperature reaches a level
higher than desired, turn the heater 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 by the thermostat, the heater and motor/pump will
turn off.
The water temperature will rise at a rate of about 2°
hour, depending on the temperature of the air surrounding
the spa. This rate will necessitate a waiting period before
using the spa, the length of which will be 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°, then it will take about 15
hours to heat up sufficiently.
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 optional spa cover available 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
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) type 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 when
the heater has just turned off, for the greatest accuracy.

Whirlpool System
You can enjoy your spa with or without activating the
whirlpool. Either way, bathing in your spa can be pleasurable, as well as therapeutic.
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 whirlpool jets are adjustable, you can direct a jet toward any location on the 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.

Filtration
When you are ready to leave the spa, select the HEATER/
FILTER mode to maintain the 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 hour per day
to allow filtration of the water and to 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 operate the spa
in the filter mode in addition.
Silent Air Induction
The intensity of the whirlpool action is determined by
how much air is inducted into the water. You have control
of this by adjusting the five air induction control knobs
located on the control panels. For maximum air induction,
rotate each control knob fully counterclockwise to the
largest dot. For fewer air bubbles, decrease the amount of
air induction by rotating the control knob clockwise. When
the knobs are turned to the smallest dot, only water is being
circulated.

MAINTENANCE
Water Quality and Water Chemistry
Maintaining water quality and 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. However, the most important part of maintaining water chemistry 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, as well as 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. We recommend that you
run your filter system for at least one hour each day. 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 bring about various undesirable water quality conditions. These conditions can be
corrected with the use of spa treatment chemicals which
are 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. (See
"Water Quality Definitions.")
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.
Hard Water: Add a de-mineralizer to break down or
deionize mineral particles present in the spa water.
Follow the “Filter Maintenance” procedure described in
this manual to ensure optimum performance of your spa’s
filtration system.
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 the type which allows you to test for
the disinfectant (chlorine) level, pH, and total alkalinity.
Also, make sure, that chemicals used in your spa are
especially for spa use and not for swimming pools, as
water quality maintenance of spas and 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 any chemicals, always run the filter system to ensure complete dilution with the water. Do not add
chemicals directly into the skimmer opening.
Disinfecting:
When filling the spa for the first time, follow the purge/
sanitizing instructions in the "Equipment Set-Up procedure" of the Installation Instructions.
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
it.
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 (see “Water Quality Definitions” below).
9
Page 13
MAINTENANCE
Water Chemistry (continued)
Superchlorinate your spa every two weeks when heavily
used. If using sodium dichlor, add one heaping tablespoon
for each 150 gallons of spa water. Scrub the spa surfaces
with this solution to remove any oily deposits. This will
ensure that any 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 a rigid 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 according to the instructions provided. pH is the measure to determine if the spa water is
too acid (low pH) or too alkaline or basic (high pH). 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 acidic water will
dissolve metals, while 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 the
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. If the spa is
used heavily, change the water at least every month.
WATER QUALITY DEFINITIONS
pH: A chemical term used in expressing 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 increasing 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 that is recommended
for spa use, as it is available in fast dissolving granular form.
It is neither excessively acid 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
10
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. It has limited effectiveness at
high water temperatures and readily affects pH balance.
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, which is approximately 6" from the top of the
rim. Evaporation and splashing will cause the water level
to drop.
When concentrations of impurities from evaporation,
water quality chemicals, body oils, perfumes, dirty feet, and
winds, 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 in the suction plumbing. Turn
the handle and drain the spa.
After draining the spa, clean the spa shell, suction
covers, skimmer, and filter, then close the hose bibb and
refill the spa with fresh water. Check the pH level and
maintain water quality.
CAUTION: Be sure to replace the suction cover immediately after cleaning. It 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.
An optional rigid spa cover, 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.
A removable filter cartridge is located inside the skimmer. To remove it, pull open the skimmer door by the
handle located in the middle of the door. Slide the basket
out, then pull the filter cartridge upward and out of the
housing by the loop at the top of the filter. 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 basket, reversing the above procedure.
Oils will coat the filter, resulting in a reduced flow. To
remove such materials, soak the cartridge in a plastic pail
containing a commercial filter cleaning solution (available
from your Jacuzzi Whirlpool Bath 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.
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, and 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 type screwdriver and clean the
cover by flushing with water from a hose.

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 syster 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 on this page), 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. (See Winterizing). Note: We do not recommend using this procedure if you are
absent during the summer when algae build-up 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:
Select the OFF mode.
1.
Turn off power to the unit at the house circuit breaker.
2.
CAUTION: Not winterizing will cause irreversible
damage (at freezing temperatures) to the pump and/
or plumbing lines.
Note: If the spa is to be used during winter in a cold
climate, see warm climate instructions below.
Drain the spa.
3.
Remove the filter cartridge, clean it, and store it dry.
4.
Keep water and debris out by covering with a rigid spa

Covering Your Spa
An optional rigid spa cover is available to place on top of the spa. Use of this cover will help to minimize heat loss and
evaporation, and thus reduce energy costs. The cover is also an attractive and efficient means of preventing debris such
as leaves and dirt from entering your spa when not in use. Follow the instructions for use and care provided with the spa
cover.
CAUTION
While the spa cover is rigid, it is not designed to support any weight. Therefore, as a safety precaution and to
preserve the life of your cover, you must not sit, stand, or lie on it; nor should you place objects of any kind on top
of it.
Jacuzzi Whirlpool Bath does not guarantee or warranty this cover. Refer to spa cover manufacturer's information
with the cover.

MAINTENANCE
Factory Installed Redwood Skirt
Your Alexa spa is supplied with a factory-installed
redwood skirt which completely surrounds the spa. The
door can be opened for routine maintenance, setting the
timer, and for testing the GFCI before use.
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. NOTE: WE RECOMMEND A WATER
BASED MATERIAL. OIL OR SOLVENT BASED FINISHING MATERIALS WILL DEGRADE THE SKIRT BACKING
MATERIAL.
If it becomes necessary to remove one or more of the
skirt panels for major service access, simply remove the
screws with which the section is secured.
To detach any of the panels, first remove all screws from
the panel being detached.
The panels can be re-attached to the spa by reversing
the above procedure.
FACTORY INSTALLED WOOD SKIRT
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, non-abrasive liquid
detergent, isopropyl alcohol, 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.

IMPORTANT
The Alexa™ Portable Whirlpool spa requires a separate 115VAC 20 AMP capacity electrical supply.
If the wiring for the circuit in which your spa is connected is not sized properly for 20 AMPS, 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 of your spa, therefore, we recommend that you test the spa's intended electrical
supply circuit for sufficient voltage. To do this, you will need as AC voltage meter and a small electric
appliance rated at 120 (min.)-1600 (max.) 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 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 10 AMP capability
to be used for the spa only. Second, you can install a transformer which would boost your existing power
to your particular electrical needs for installation of your spa.
