Important Safety Instructions
WARNING:
To reduce the risk of drowning, electric shock, or serious injury, read the fol-
lowing important precautions before using the hydrotherapy spa.
READ AND FOLLOW ALL INSTRUCTIONS
1. It is the responsibility of the owner to ensure
that all users of the hydrotherapy spa are
adequately informed of all precautions.
10. Never insert any object into any opening.
11. Do not use breakable containers in or near
the hydrotherapy spa.
2. Use the hydrotherapy spa only as described
in this manual.
12. Do not sit on the spa cover or place objects
on it; it is not designed to support weight.
3. The hydrotherapy spa is intended for home
use only. Do not use the spa in a commercial,
rental, or institutional setting.
13. Remove any water or debris that may collect
on the spa cover.
14. Keep children under the age of 12 and pets
away from the hydrotherapy spa when it is
not in use.
4. Use the hydrotherapy spa only on a level sur-
face. Do not use the spa on carpet or other
materials that could be damaged by moisture.
15. Keep all chemicals away from children and
pets.
5. The hydrotherapy spa will weigh approxi-
mately 2,133 pounds when it is filled with
water. Make sure that the location you select
for the spa will support this weight, plus the
weight of the occupants.
16. The pH and chemical balance of the water
must be maintained as explained in this man-
ual (see pages 10 and 14). Failure to do so
may cause injury to users or damage to the
hydrotherapy spa, and will void the warranty.
6. Inspect and tighten all parts regularly.
Replace any worn parts immediately.
17. Individuals with infections and open sores or
wounds should not use the hydrotherapy
spa. Bacteria thrive in warm and hot water.
Always keep your spa disinfected and main-
tain the proper chemical balance.
7. DANGERÑRisk of injury: Do not remove or
alter the covers on the suction fittings. Never
operate the hydrotherapy spa if the suction
guard is missing or broken. If you need to
replace a suction fitting or pump, make sure
you use only manufacturer recommended
replacement parts. Keep hair and body parts
away from the suction guard. Do not allow
long hair to float freely in the water; long hair
should be restrained with a bathing cap.
18. Shower before and after using the hydrother-
apy spa. This will remove any deodorant, per-
spiration, or body oils that could contaminate
the water. Showering after will remove any
residual chemicals and any bacteria that may
have been in the spa.
8. IMPORTANT: Do not allow the hydrotherapy
spa to be exposed to direct sunlight when it
is empty. The surface of the spa shell can
reach temperatures as high as 150¡F in a mat-
ter of minutes if exposed to the sun while it is
empty. These high temperatures can cause
significant damage, such as blistering of the
shell surface and warping of the spa shell.
Any damage caused by sun exposure is not
covered under the warranty.
19. DANGERÑWhen connecting the power cord
(see PLUGGING IN THE HYDROTHERAPY
SPA on page 10), plug the power cord directly
into a grounded circuit capable of carrying 15
or more amps. No other appliance should be
on the same circuit. Replace the power cord
immediately if damaged.
20. Do not use an extension cord with the
hydrotherapy spa. This could damage the
motor and will void the warranty.
9. Do not bring any object into the hydrotherapy
spa that could damage the spa shell.
3
21. DANGERÑIf you will be using the hydrother-
apy spa outside, do not bury the power cord.
Keep the power cord away from lawn mow-
ers, hedge trimmers, and other similar equip-
ment.
29. WARNINGÑTo reduce the risk of injury: The
water temperature should never exceed
104¡F. Temperatures between 100¡F and 104¡F
are considered to be safe for healthy adults.
However, if you plan to remain in the hydro-
therapy spa for more than 10 to 15 minutes, a
lower temperature is recommended. Lower
temperatures are also recommended for chil-
dren. Children should not be allowed to swim
under the surface of the water in the spa.
22. WARNINGÑThe power cord is equipped with
a Ground Fault Circuit Interrupter (GFCI),
located on the power cord. The GFCI must be
tested before each use. To test the GFCI,
press the ÒtestÓ button while the hydrothera-
py spa is running. The should shut off. Press
the ÒresetÓ button. The spa should resume
normal operation. If the spa continues to run
after the ÒtestÓ button is pressed, the GFCI is
damaged. Do not use the spa until the GFCI
has been repaired or replaced by a qualified
electrician.
30. WARNINGÑTo reduce the risk of injury:
Before entering the hydrotherapy spa, always
use an accurate thermometer to determine
the water temperature.
31. WARNINGÑTo reduce the risk of injury:
Pregnant women should consult with their
physician before using the hydrotherapy spa.
Pregnant women should not use the spa if
the water temperature is above 100¡F; the
unborn child could be seriously harmed. This
is especially important during the first 90
days of the pregnancy.
23. DANGERÑRisk of electric shock. Keep all
electrical appliances such as radios, tele-
phones, televisions, and lights at least five
feet away from the water.

motor of the hydrotherapy spa to connect a
minimum No. 8 AWG (804 mm2) solid copper
conductor between the spa and any metal
equipment, electrical enclosure made of
metal, metal water pipes, or conduit within
five feet of the spa.
32. DANGERÑTo reduce the risk of drowning:
Prolonged immersion in the hydrotherapy spa
may cause hyperthermia, a dangerous condi-
tion that occurs when the internal body tem-
perature rises several degrees above the nor-
mal body temperature of 98.6¡F. The symp-
toms of hyperthermia are nausea, dizziness,
drowsiness, and fainting. Effects include: a
lack of awareness, inability to perceive heat
or danger, and a greater risk of drowning due
to a loss of consciousness. Special note:
Individuals suffering from hyperthermia may
be unable to realize that they must exit the
spa, and they also may be physically unable
to do so.
25. DANGERÑRisk of electric shock: Do not set
the hydrotherapy spa within five feet of any
metal objects or surfaces. As an alternative,
you may use the spa within five feet of metal
objects if each metal object is permanently

Using the Hydrotherapy Spa
The hydrotherapy spa is designed to seat five adults.
The spa holds 225 gallons of water and offers a heat-
ing system (70¡F to 104¡F), a filtration system, ten
adjustable hydrotherapy jets, and a powerful whirlpool
jet. Follow the guidelines below to use and maintain
the spa for your long-term enjoyment.
TESTING AND TREATING THE WATER
The hydrotherapy spa comes with a starter chemical
pack for maintaining the water in the spa. Disregard
the directions on the individual packages of ÒQUICK
pHix It DOWNÓ and ÒQUICK pHix It UP.Ó However, the
directions on the bottle of ÒNon-chlorine ShoxÓ and
ÒBromine BaseÓ are correct. Always keep the chemi-
cals away from children and pets.
PLUGGING IN THE HYDROTHERAPY SPA
Important: The hydrotherapy spa is equipped with a
120/240V convertible electronics package. Operation
at 240V will allow the heater to run more efficiently
and less often. Conversion of the spa to 240V oper-
ation must be performed only by a qualified,
licensed electrician and must comply with all
local, state, and federal electrical codes. Please
refer to the instructions on the inside of the electronics
package for information about converting the spa to
240V operation.
The first time you use the spa, you should test and
treat the water. You must also treat the water each
time you refill the spa. Once you have verified that
the spa is functioning properly, and have allowed the
water to circulate for a while, you should remove the
spa cover and add 1/3 of the ÒBromine BaseÓ bottle,
and 1/3 of the ÒNon-chlorine ShoxÓ bottle to the water
in the spa. Allow the water to circulate for five min-
utes. You should now test the pH level of the water by
using the included test strips. Refer to the test strip
packaging for instructions on using the test strips. The
pH reading should be between 7.2 and 7.8.
Once the hydrotherapy spa is filled with water, the
power cord can be plugged in and the spa can be
turned on. Note: The first time the power cord is
plugged in, the spa will turn on automatically.
If the level is too low, add half of one of the ÒQUICK
pHix It UPÓ packets to the water. Let the water circu-
late through the spa for five minutes. Test the pH level
again. Repeat until the pH level is correct.
When connecting the power cord, plug the power cord
directly into a grounded circuit capable of carrying 15
or more amps. No other appliance should be on the
same circuit. Replace the power cord immediately if it
becomes damaged.
If the level is too high, add half of one of the ÒQUICK
pHix It DOWNÓ packets to the water. Let the water cir-
culate through the spa for five minutes. Test the pH
level again. Repeat until the pH level is correct.

Light Button: Turns the underwater light on and off.
Temperature Buttons: Control the temperature setting
of the water. The temperature can be set at 70¡F to
104¡F. The water heats at about 1.8¡F per hour with
the cover on. Use a medical or other accurate ther-
mometer to check the temperature of the water. Note:
The word ÒCOOLÓ will appear in the console display if
the temperature of the water is more than 20¡F cooler
than the set temperature. When this happens, the
heater will automatically activate to warm the water.
The word ÒICEÓ will appear in the display if the tem-
perature drops below 40¡F. If this happens, the pump
will automatically circulate the water and warm the
plumbing to keep the water from freezing.
Air Control: Determines the amount of air flowing
through the hydrotherapy jets during operation. If the
control is turned counterclockwise, the amount of air
flowing through the jets will increase. If the control is
turned clockwise, the amount of air will decrease.
Diverter: Controls the flow of water through the
hydrotherapy jets and the whirlpool jet. When the
diverter is turned fully clockwise, the flow will be
through the whirlpool jet; when the diverter is turned
fully counterclockwise, the flow will be through the
hydrotherapy jets; when the diverter is halfway
between the clockwise and counterclockwise posi-
tions, the flow will be evenly distributed through the
whirlpool jet and the hydrotherapy jets.

ton is pressed once, the spa jets will run at low speed,
providing gentle hydrotherapy. If the button is pressed
again, the jets will run at high speed, providing more
intense hydrotherapy. If the button is pressed a third
time, the jets will shut off.
The spa also features an automatic mode that heats
and filters the water when the spa is left unattended.
When the spa is first plugged in, or if the buttons on
the console have not been pressed for longer than
twenty minutes, the automatic mode will begin filtering
or heating the water as needed. Note: To keep the
filter and heat cycles from running, the power
cord must be unplugged.

the spa cover, use water and a non-abrasive cleaner
on the entire cover. Rinse the cover with a garden
hose to remove any cleaner residue. Dry the cover
entirely. Use a non-silicone-based vinyl conditioner on
the cover after you clean it. This will help protect the
cover from sun damage.
MAINTENANCE SCHEDULE
Daily
¥ Check the water level and refill the spa to the level
shown in step 3 on page 9.
¥ Check the pH balance and sanitizer level. Adjust if
necessary (see WATER CHEMISTRY on page 14).
¥ Clean the surface of the water with a skimming net.
SANITIZING THE HYDROTHERAPY SPA
Please refer to your local pool and spa supplier for
information concerning which chemicals you should
use in your area to sanitize the spa.
Weekly
¥ Clean the spa shell at the waterline.
¥ Check and thoroughly clean the filter (see CHECK-
ING AND CLEANING THE FILTER on this page).
¥ Replace the filter if needed (see ORDERING
REPLACEMENT PARTS on the back cover).
The most common sanitizing agent is a solid bromine
concentrate. The amount required varies according to
several factors, such as user load, temperature, water
conditions etc. Proper water maintenance is a fairly
complex process. We recommend that you contact
your local pool and spa supplier for information on
how you should best accomplish this.
Monthly
¥ Clean the spa cover (see MAINTAINING THE SPA
COVER on this page).
¥ Soak the filter for two hours in a trisodium phos-
phate (TSP) solution. Rinse the filter in clean water.
¥ Replace the filter if needed (see ORDERING
REPLACEMENT PARTS on the back cover).
CHECKING AND CLEANING THE FILTER
The filter should be checked periodically for build-up
of dirt and oil. If the filter needs to be cleaned, follow
the steps below:
Every Three Months
¥ Drain the spa and refill it with clean water. Sanitize
and test the pH of the water.
1. Turn off the power.
Locking
Ring
¥ Check for any leaks around the pump or joints in
the pipes. The seals will wear out over time; detect-
ing leaks early can reduce repair costs.
¥ Clean the interior of the spa. Do not use solvents or
waxes.
2. Turn the air vent
counterclockwise to
open it.
3. Unscrew the locking
ring and pull out the
filter cover.
4. Lift the top filter gas-
ket and the filter out

WATER CHEMISTRY
ATTACHING AND REMOVING THE ACCESS PANEL
The hydrotherapy spa comes with a starter chemical
pack for maintaining the water in the spa. (See TEST-
ING AND TREATING THE WATER on page 10.)
Additional chemicals can be purchased at a pool and
spa supply store.
To locate the access panel, refer to the drawing on
page 6. To remove the access panel, first remove the
four indicated screws. Slide the access panel down
and then pull the bottom of it away from the spa. Be
careful not to damage the spa shell as you
remove the access panel.
CAUTION: The chemicals used to maintain the pH
balance of the water and to sanitize the water can
be dangerous. Always follow these basic guide-
lines when handling the chemicals:
1. Always read and follow the directions on the
label, unless directed otherwise.
Access
Panel
2. Never mix different chemicals.
3. Do not exceed the recommended amounts of
chemicalsÑfollow the directions on the label
closely.
4. Keep all chemicals out of the reach of children
and pets.
5. Keep all containers closed tightly when not in
use.
6. Never add water to the chemicalsÑalways add
the chemicals to the water as directed.
7. Always store chemicals in a cool, dry place.
Screws
To replace the access panel, insert the top of the
access panel under the edge of the spa shell. Slide
the cover up until the bottom of the access panel
clears the trim along the bottom of the spa. Then,
slide the access panel into place and re-attach the
four screws.
MAINTAINING THE PROPER PH BALANCE
The pH factor is a measure of the relative acidity or
alkalinity in the water. It is measured on a scale of 1
to 14. Pure water has a value of 7, which is neutral.
Any value above 7 is alkaline, and any value below 7
is acidic. You should maintain a slightly alkaline pH
level, between 7.2 and 7.8, in the hydrotherapy spa.
DRAINING THE HYDROTHERAPY SPA
The hydrotherapy spa should be drained at least four
times a year and refilled with clean water. You may
need to drain the spa more often, depending on the
user load. This must be done because after repeated
chemical treatment the water becomes chemically
saturated. Once this happens, additional chemical
treatment of the water is no longer effective. The spa
should also be drained if you will not be using it for
long periods of time. The spa must always be drained
before major repairs are made.
Severe problems can occur when the pH balance is
not maintained within this range. If the pH level
exceeds 7.8, dissolved minerals can build up and clog
the plumbing in the spa jet unit. If the pH level falls
below 7.2, the acid level in the water will begin to cor-
rode the metal parts in the spa jet unit. Also, the sani-
tation agents in the water will not be effective if the pH
level is not properly maintained. Damage caused by
improper pH levels is not covered under the warranty.
The hydrotherapy spa should always be covered
when it is empty. Direct sunlight can cause exten-
sive damage. The surface of the spa shell can
reach temperatures as high as 150¡F in a matter
of minutes if exposed to the sun while it is empty.
These high temperatures can cause significant
damage, such as blistering of the shell surface
and warping of the spa shell. Any damage caused
by sun exposure is not covered under warranty.
To maintain the proper pH level, you should test the
pH of the water regularly. To test the water, you can
either purchase additional test strips or purchase a pH
test kit at a pool and spa supply store. The pH read-
ing should be between 7.2 and 7.8. If the level is too
low, add a pH increaser (usually soda ash). If the
level is too high, add a pH reducer (usually sodium
bisulfate). Test the water again after five minutes. See
the instructions with your pH test kit for additional
information about testing and adjusting the pH.

To drain the hydrotherapy spa, follow the steps below:
WINTER USE AND CARE
1. Using the console, adjust the temperature to the
lowest setting.
The hydrotherapy spa is designed for year-round use.
If you decide to store the spa for the winter, store it in
a warm, dry location. Follow the steps below to winter-
ize the spa.
1. Drain the spa (see DRAINING THE HYDROTHER-
APY SPA on the previous page and this page).
2. Remove all remaining water from the spa shell. Dry
the spa shell with towels.
2. Shut off the circuit breaker or GFCI.
3. Remove the access panel from the spa.
4. Remove the end of the drain hose from the spa.
Remove the cap and attach a garden hose to the
drain hose.
3. Set the air control to the lowest setting. Use a
wet/dry vacuum to pull any remaining water from
the system. To do this, place the vacuum nozzle
over each jet, starting with the highest jet and fin-
ishing with the lowest jet.
4. Set the air control on the console to the highest
setting and repeat step 3.
5. Drain the pump (see DRAINING THE PUMP on
this page). Once the water is drained from the
pump, place the vacuum nozzle over the drainage
hole in the pump and vacuum any additional water
from the pump. Note: For additional protection,
remove the pump/motor from the spa and store
it in a climate-controlled room.

6. Clean the spa shell (see page 13).
7. Clean the filter (see page 13).
8. A qualified electrician should disconnect the power
cord from the 240V power source.
9. Re-attach the access panel and the spa cover.
5. Open the valve by turning the valve knob. The
water will begin to drain.
6. When the spa is empty, close the valve and
remove the garden hose. Re-attach the cap and
return the drain hose to the clip inside the spa.
7. Re-attach the access panel.
8. Refill the spa and treat the water with chemicals
(see pages 10 and 14).
REPLACING THE LIGHT BULB
If the underwater light burns out, you will need to
remove the access panel to replace it (see ATTACHING
AND REMOVING THE ACCESS PANEL on page 14).
Next, locate the light housing. Turn the light housing
counterclockwise and remove it from the spa shell.
DRAINING THE PUMP
After the hydrotherapy
spa is drained (see
DRAINING THE
Light Housing
Light
Bulb
HYDROTHERAPY SPA
on page 14), the pump
should also be drained
if the hydrotherapy spa
will be stored for more
than thirty days or if it
may be exposed to
freezing temperatures.
Light
Housing
Drain Plug
To replace the light bulb, pull the old light bulb out of
the housing and insert a new light bulb. Re-attach the
light housing to the spa shell. Re-attach the access
panel to the spa.
To drain the pump, remove the access panel from the
spa unit (see ATTACHING AND REMOVING THE
ACCESS PANEL on page 14). Locate the pump inside
the spa unit. Remove the drain plug from the pump
and allow all water to drain from the pump. Replace
the drain plug.

4. SYMPTOM: THE PUMP HUMS, BUT DOES NOT
ROTATE
8. SYMPTOM: THE WATER PULSATES OR
THERE IS MINIMUM WATER FLOW
a. The pump may be jammed. Contact our cus-
tomer service department. If your spa is no
longer under warranty, contact a local spa and
pool service provider.
a. This usually occurs only when the water level is
low. Add water until the jets are covered (see
step 3 on page 9).
5. SYMPTOM: THE PUMP IS NOISY WHILE
OPERATING
9. SYMPTOM: THE WATER LEVEL DROPS
a. There may be debris in the pump. Contact our
customer service department.
a. Some water loss due to evaporation is normal.
If rapid water loss occurs, or if you notice wet-
ness on the floor around the hydrotherapy spa,
the spa shell may have a leak. Contact your
local pool and spa service provider for repairs.
b. The pump may have a bad bearing. Contact
our customer service department.
6. SYMPTOM: THE WATER DOES NOT HEAT
b. A clamp or seal inside the pump compartment
may be loose. Check inside the pump compart-
ment for excess water and watch the pump unit
while it is operating to see if water drips from
any of the plumbing. If you can identify the
location of the leak inside the spa jet unit, tight-
en the clamp or replace the damaged seal.
a. Make sure that the hydrotherapy spa is fully
covered with the spa cover. The spa cover
must be tight for the water to heat. Set the
air control to low. The water will heat at a rate
of 1.8¡F per hour. If you are using the spa
indoors and the room temperature is main-

once. To turn the spa jets on high, press the jet
button twice. To turn the spa jets off, press the
button three times. The spa jets will remain off
for two hours, at which time they will begin run-
ning the filter cycle. At any time after the spa
jets have been shut off, the pump will begin
cycling the water if the temperature falls below
the minimum setting. Note: If the water tem-
perature is already below the minimum set-
ting, the pump will not shut off.
a. This is a normal function of the spa; no action
is necessary. The word ÒCOOLÓ will appear in
the display if the temperature of the water is
more than 20¡F cooler than the set tempera-
ture. If this happens, the heater will automati-
cally activate to warm the water. The word
ÒICEÓ will appear if the temperature drops
below 40¡F. If this happens, the pump will auto-
matically circulate the water and warm the
plumbing.
