INSTALLATION  
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.  
4. Before installation begins, remove the owner's  
packetfromtheaccessorypackage. Thispackage  
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 war-  
ranty card. (See illustration on page 1 for the serial  
number location.)  
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.  
5.  
Place the filter cartridge in a dry place for later use.  
3.  
If, afterhavingbeenremovedfromthecarton, thespa  
must be turned onto its side to move it, make sure the  
surfaceofthecartordollyonwhichitisplacedislarge  
enough to support the entire width of the spa, includ-  
ing 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 equip-  
ment door side. See illustration at lower right.  
Important! Read all the instructions contained 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 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  
circuithavingnootherapplianceconnectedinthatcircuit. Ifyoudonothavea115VAC20AMP circuit, aqualifiedelectrician  
should be called in to install the necessary wiring. Inadequately sized wiring may cause a voltage drop which might cause  
theunittomalfunctionandbringaboutpermanentdamagetothespa’selectricalsystem. Thecircuitmustalsohaveaground  
wireinordertotakeadvantageofthedesigned-insafetyfeaturesofthespa. Abondwiremustalsobeused. Bondaccording  
to procedure described on the next page.  
Caution: Without proper grounding and bonding, a system malfunction may cause fatal shock.  
Electrical Precaution  
4. Do not use electrically connected devices, such as televi-  
sion, radio, telephones, stereo speakers, light or cooking  
devices within 5 ft. of the spa when the spa is being used.  
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 EXTEN-  
SION 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 malfunc-  
tion.  
5. All fixed metal objects located within 5 ft. of the spa, such  
as fence posts, railings, door frames, greenhouse struc-  
tures, 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 electri-  
calsupplystore. (Seeillustrationonpage5forbondbar  
location.)  
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.  
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.  
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 Inter-  
rupter).  
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 inef-  
fective would cause electrical shock. Such modification  
would also nullify the warranty.

INSTALLATION  
Outdoor Installations  
Drainage  
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  
mesh6"x6"steelreinforcedgrid. Attacha#8solidcopperwire  
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.  
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  
tokeepwaterfromcollectingatthebaseofthespa—especially  
neartheequipmentarea. Ifdrainageispoor, installadrainline  
and/or gravel drain field. (See illustration below.)  
Optional Timer Installation  
Indoor Installations  
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  
ratingof20AMPSfor1HPwiththerequired20AMPreceptacle  
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.  
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  
moistureorwaterspillage. Consultanarchitectorengineerfor  
aid in designing your indoor installation.

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.  
At the house service panel, turn on the circuit breaker or  
a switch that controls the electrical service to your spa.

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.

quence, since that function is the most obvious when  
operating.  
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.

Setting the Thermostat  
Turn on the heater by selecting the HEATER/FILTER  
mode on the selector switch.  
Notes on Determining Water Temperature:  
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.  
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 mea-  
surement of spa water temperature. Other types of ther-  
mometersgenerallyavailable, suchasthoseusedforswim-  
ming pools, are not sufficiently accurate to determine spa  
watertemperatures. Takewatertemperaturereadings when  
the heater has just turned off, for the greatest accuracy.  
The heater adjustment knob is located on the control  
panel. Toset thethermostat, rotatetheknobtothedesired  
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

ture. 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.  
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 adjust-  
able, 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.

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

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  
Water Chemistry  
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 undesir-  
able 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:  
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 espe-  
cially 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 deter-  
mine 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 chemis-  
try.  
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 accu-  
mulateonthefilterelementandclogitspores. Theaddition  
of clarifier will make the water clearer, but clogged filters  
must be cleaned as prescribed under the section entitled  
“Filter Maintenance” in this manual.  
When adding any chemicals, always run the filter sys-  
tem 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 proce-  
dure" of the Installation Instructions.  
Add a disinfectant to the water on a regular basis to help  
controltheamountofbacteria,algaeandorganicmaterials.  
Such bacterial contaminants, if not controlled, could cause  
skinrashesorotherphysicalproblems. Todisinfectthespa  
for normal use, first establish the amount of chlorine or  
bromine to add and determine how often you need to add  
it.  
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.  
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

Water Chemistry (continued)  
Balancing Total Alkalinity:  
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 disin-  
fectant,runthefiltersystemandallowthefreechlorinelevel  
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  
levelisbacktonormal.Highconcentrationsofchlorine  
or bromine will damage metallic plated finishes if the  
cover is in place.  
Total alkalinity is the measure of base materials in the  
water. The recommended range for total alkalinity is be-  
tween 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  
amountoffreeavailablechlorine.Ifthealkalinityofyourspa  
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.  
Balancing pH:  
Forgoodhygieneandequipmentlongevity,maintainthe  
pH of your spa water according to the instructions pro-  
vided. 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 bicarbon-  
ate 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.  
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.  
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  
inexpensiveandeffectivebutnotrecommendedbecausethe  
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.  
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.  
Total alkalinity: The measure of the amount of alkaline  
materials (such as carbonates, bicarbonates and hydrox-  
ides) in the water. High alkalinity inhibits the effectiveness of

MAINTENANCE  
Filter Maintenance  
Water Level/Drain  
The filter should be checked periodically. In normal use,  
check the filter at least once a month. Keep the filter clean;  
anobstructedfilterreduceswaterqualityandinhibitsproper  
system performance.  
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.  
A removable filter cartridge is located inside the skim-  
mer. 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  
waterfromagardenhose. Thenreinstallthecartridgeinthe  
housing and replace the basket, reversing the above pro-  
cedure.  
When concentrations of impurities from evaporation,  
waterqualitychemicals, bodyoils, perfumes, dirtyfeet, 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.  
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 phos-  
phate (TSP) and water. An hour of soaking time is usually  
required to break down oil coatings from the cartridge. Use  
astrongersolutionofTSPandwatertoremovealgae. Most  
hardware or paint stores stock TSP. Use the same method  
of cleaning when the cartridge becomes plugged with clay  
or vegetation.  
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 imme-  
diately 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.  
Suction Strainer Maintenance  
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.  
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.  
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 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.

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

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  
Cleaning Your Spa  
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.  
Your spashellconsistsoftwolayersofplasticmaterials.  
Its smooth top surface of acrylic is tough and durable and  
contains concentrated color. This is supported by a sub-  
stantial 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.  
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 appro-  
priate product. NOTE: WE RECOMMEND A WATER  
BASED MATERIAL. OIL OR SOLVENT BASED FINISH-

IMPORTANT  
The AlexaPortable 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
