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 2,900 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. DANGER—Risk 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. WARNING—The Ground Fault Circuit  
Interrupter (GFCI), must be tested before  
each use. To test the GFCI, press the “test”  
button while the hydrotherapy spa is running.  
The spa should shut off. Press the “reset”  
button. The spa should resume normal opera-  
tion. If the spa continues to run after the  
“test” button is pressed, then the GFCI is  
damaged. Do not use the spa until the GFCI  
has been repaired or replaced by a qualified  
electrician.  
9. Do not bring any object into the hydrotherapy  
spa that could damage the spa shell.

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.  
21. A wire connector is provided on the electron-  
ics pack of the hydrotherapy spa to connect a  
minimum No. 6 AWG (13.3 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.  
29. DANGER—To reduce the risk of drowning:  
Prolonged immersion in the hydrotherapy spa  
may cause hyperthermia. The causes, symp-  
toms and effects of hyperthermia may be  
described as follows: Hyperthermia occurs  
when the internal temperature of the body  
reaches a level several degrees above the  
normal body temperature of 98.6°F. The symp-  
toms of hyperthermia include an increase in  
the internal temperature of the body, dizzi-  
ness, lethargy, drowsiness and fainting. The  
effects of hyperthermia include failure to per-  
ceive heat; failure to recognize the need to  
exit the spa or hot tub; unawareness of  
impending hazard; fetal damage in pregnant  
women; physical inability to exit the spa or  
hot tub and unconsciousness resulting in  
danger of drowning. WARNING: The use of  
alcohol, drugs or medication can greatly  
increase the risk of fatal hyperthermia.  
22. DANGER—Risk 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  
connected to the wire connector on the elec-  
tronics pack of the spa by a minimum No. 6  
AWG (13.3 mm2) solid copper conductor (see  
instruction 21).  
23. Do not operate the pump motor when the  
hydrotherapy spa is empty. The pump motor  
may be seriously damaged if it is operated  
without water circulating.  
24. DANGER—Risk of drowning: Exercise  
extreme caution to prevent unauthorized and  
unsupervised use of the hydrotherapy spa by  
children. Children must always be supervised.  
30. WARNING—To reduce the risk of drowning:  
Do not use the hydrotherapy spa if you are  
under the influence of alcohol or drugs. Heat  
from the water, in conjunction with alcohol or  
drugs, can cause loss of consciousness.  
25. DANGER—To reduce the risk of drowning:  
• Never use the hydrotherapy spa alone.  
• Children should not use the spa unless they  
are supervised by an adult.  
31. WARNING—To reduce the risk of injury or  
drowning: Consult your physician about pos-  
sible side-effects of any medications you may  
be taking before using the hydrotherapy spa.  
Heat from the water, in conjunction with some  
medications, may cause drowsiness and  
increase the risk of drowning. Other medica-  
tions can effect blood pressure, heart rate,  
and circulation.  
• Keep pets away from the spa at all times.  
• Always replace and lock the spa cover when  
the spa is not in use.  
26. WARNING—To 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.  
32. Do not use the hydrotherapy spa immediately  
after strenuous exercise.  
33. If you feel pain or dizziness at any time while  
using the hydrotherapy spa, discontinue use  
and contact a physician.  
34. WARNING—To reduce the risk of injury: It is  
especially important for persons over the age

Choosing a Location for the Hydrotherapy Spa  
There are many factors to consider when choosing a location to set up the hydrotherapy spa. These factors vary  
depending on whether you plan to use the spa inside or outside. We have listed several factors you may wish to  
consider as you decide where to set up the spa.  
If you set up the hydrotherapy spa inside:  
If you set up the hydrotherapy spa outside:  
1. The spa will increase the level of humidity in your  
home. The location you choose should be well  
ventilated. You may need to install a ventilation fan  
or use a dehumidifier.  
1. Check local building codes concerning the use of  
outdoor spas.  
2. The spa should be located near a 240-volt power  
source. It must be wired directly into a grounded  
circuit with a Ground Fault Circuit Interrupter  
(GFCI) capable of carrying 30 amps. No other  
appliance should be on the same circuit.

source. It must be wired directly into a grounded  
circuit with a Ground Fault Circuit Interrupter  
(GFCI) capable of carrying 30 amps. No other  
appliance should be on the same circuit.  
3. The spa should be close to a source of water.  
3. The spa should be close to a source of water.  
4. We recommend that you place the spa on a water-  
and stain-resistant, non-slip surface. Do not use  
the spa on rough or sharp surfaces such as gravel  
or wood chips.  
4. Do not use the spa on carpet or other material that  
may be damaged by moisture. We recommend  
that you place the spa on a water- and stain-resis-  
tant, non-slip surface with a floor drain for any  
water that may splash from the spa.  
5. Be sure that the location you choose is stable. It  
must be able to support the weight of the spa  
when it is filled with water, plus the weight of the  
occupants. The spa weighs approximately 2,900  
pounds when it is filled with water.

6. Consider environmental factors such as rain, wind,  
shade, sunlight, and so forth.  
6. Do not use the spa above a finished living area,  
due to the risk of water damage.  
7. You should be able to monitor the use of the spa  
from your home, to prevent unauthorized use by  
children. You may want to enclose the spa with a  
fence and self-latching gate to prevent unautho-  
rized use.  
7. Be sure that there is room around the spa to per-  
mit servicing of the unit. The dimensions of the spa  
are 84” W x 84” L x 36” H. You should allow for this

Using the Hydrotherapy Spa  
The hydrotherapy spa is designed to seat six adults.  
The spa holds 300 gallons of water and offers a heat-  
ing system (80°F to 104°F), a filtration system, and  
adjustable hydrotherapy jets. Follow the guidelines  
below to use and maintain the spa for your long-term  
enjoyment.  
CONTROLS on page 12). Once the spa is running,  
press the GFCI “test” button. The spa should shut off.  
Press the “reset” button. The spa should resume nor-  
mal operation. If the spa continues to run after the  
“test” button is pressed, the GFCI is damaged. Do not  
use the spa until the GFCI has been repaired or  
replaced by a qualified electrician.  
WIRING THE HYDROTHERAPY SPA  
Once you have tested the GFCI, you should verify the  
water flow from the pumping unit. Set the air control  
on the console to the lowest setting (see USING THE  
CONTROLS on page 12). The pumping unit will heat  
the water as it pumps. Cover the hydrotherapy spa  
with the spa cover. The spa cover must be tight  
(see SECURING THE SPA COVER ON THE SPA  
below). The water will heat at about 6°F per hour with  
the cover on. If you are using the spa indoors, and  
the room temperature is maintained at 70°F, it will  
take approximately 6 to 8 hours for the water to reach  
the set temperature.  
The hydrotherapy spa is designed to operate with a  
240-volt power source. It must be wired directly into a  
grounded circuit with a Ground Fault Circuit  
Interrupter (GFCI) capable of carrying 30 amps. No  
other appliance should be on the same circuit.  
Connection of the spa to the 240-volt power  
source must be performed 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 connecting the spa to a 240-volt  
power source.  
The temperature and the water flow can be set or  
changed with the controls on the console (see USING  
THE CONTROLS on page 12).  
Once the spa is filled with water, the power can be  
turned on. Note: The first time the power is turned on,  
the spa will start automatically.  
SECURING THE SPA COVER ON THE SPA  
TESTING AND TREATING THE WATER  
To secure the spa cover,  
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. A test strip and a chemical  
pack are available at your local pool and spa store.  
Follow the directions carefully on the chemical pack to  
test and treat the water. Always keep the chemicals  
away from children and pets.

K. The nine rotary jets provide a spinning massage.  
E. The whirlpool jet diverts the water flow four ways.  
Turn the outer ring clockwise or counterclockwise  
until the ring stops and you hear a click. With each  
click, the water flow is diverted as follows: to seat 3,  
and the jet labeled D; next, to the seats labeled 1, 4,  
5, and 6; next, to the whirlpool jet; and then to all  
the jets and seats. Note: The outer ring may be  
hard to turn while the pump is turned on high.  
L. The six dual rotary jets provide a pulsating mas-  
sage action. Rotate the outer ring counterclockwise to

regardless of the position of the whirlpool jet (E).  
M. The two power massage jets provides a soothing  
massage to your lower back. Turn the outer ring to  
regulate the flow.  
F. The two suction covers provide water to the pump.  
Never operate the spa without the suction covers in  
place over the fittings.  
N. The four adjustable, directional jets can be pivoted  
to direct their water flow. To open the jets, turn the  
outer rings counterclockwise; to close the jets, turn the  
outer rings clockwise. If no air flows through the jets,  
turn the jets counterclockwise. Close the jets to  
increase the water pressure to other jets.  
G. The ozone jet provides ozone sanitation to the spa.  
The ozone generator engages during the spa’s filtra-  
tion cycles to destroy algae, viruses, and bacteria  
while breaking down chemicals and solids for easy  
removal by the filtration system. Ozone oxidizes com-  
bined chlorine and bromine, freeing them to be con-  
tinuously re-used, reducing the chemical needs and  
costs of the spa’s sanitation.

WATER CHEMISTRY  
MAINTAINING THE SPA EXTERIOR  
The maintenance of the pH level is very important to  
the operation of the spa. To maintain the proper pH  
level and to sanitize the spa, you can purchase a  
chemical starter kit from your local pool and spa sup-  
ply store.  
The premium cedar surround has been treated at the  
factory. For information and supplies to maintain the  
beauty and color of the premium cedar surround, con-  
tact your local pool and spa supply store.  
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.  
CLEANING THE SPA SHELL  
The spa shell should be cleaned with a mild soap  
solution; do not use solvents. The spa should always  
be clean and dry before being moved or stored.  
2. Never mix different chemicals.  
MAINTAINING THE SPA COVER  
3. Do not exceed the recommended amounts of  
chemicals—follow the directions on the label  
closely.  
4. Keep all chemicals out of the reach of children  
and pets.  
The spa cover should be cleaned monthly. To clean  
the spa cover, use water and a non-abrasive cleaner  
on the entire cover. Rinse the cover with a garden  
13  
 
5. Keep containers closed tightly when not in use.  
6. Never add water to the chemicals—always add  
the chemicals to the water as directed.  
REMOVING AND ATTACHING THE ACCESS PANEL  
To locate the access panels, refer to the drawing on  
page 6. Turn off the power to the spa. To remove an  
access panel, first remove the four indicated screws.  
Slide the access panel down and then pull the bottom  
of it away from the spa. Note: Be careful not to  
damage the spa shell as you remove the access  
panel.  
7. Always store chemicals in a cool, dry place.  
MAINTAINING THE PROPER PH BALANCE  
The pH factor is a measure of the relative acidity or  
alkalinity in the water, and 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.  
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.  
Screw  
Access  
Panel  
Screw  
To maintain the proper pH level, test the pH of the  
water regularly. To test the water, purchase a pH test  
kit at a pool and spa supply store. The pH reading  
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 infor-  
mation about testing and adjusting the pH.  
To re-attach the access panel, insert the top of the  
access panel under the edge of the spa shell. Slide  
the access panel 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  
it with the four screws.  
DRAINING THE HYDROTHERAPY SPA  
SANITIZING THE HYDROTHERAPY SPA  
The hydrotherapy spa should be drained at least four  
times per 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.  
The most common sanitizing agent is a solid bromine  
concentrate. The amount required varies according to  
several factors, such as user load, temperature, and  
water conditions. Proper water maintenance is a com-  
plex process. Contact your local pool and spa supplier  
for information concerning which chemicals you  
should use in your area to sanitize the spa.  
CHANGING THE FILTER CYCLE  
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.  
The spa will filter the water every 12 hours. The dura-  
tion of the cycle can be adjusted to last 2 to 5 hours.  
Press the temperature up or temperature down button  
on the console. When the display begins to flash,  
press the pump button. The display will read F2. To  
change the time, press the temp up button until the  
desired time is reached. Press the pump button to  
confirm the selection. As spa usage increases, the  
duration of the filter cycle may need to be increased.

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  
2. Shut off the power to the spa, at the circuit breaker a warm, dry location. Follow the steps below to winter-  
or GFCI.  
ize the spa.  
3. Remove the pump access panel from the spa.  
4. Pull the hose out and hold it above the waterline.  
Remove the cap and attach a garden hose to the  
drain hose. Lower the hose and drain the spa.  
1. Make sure the power to the spa is turned off.  
2. Drain the spa (see DRAINING THE HYDROTHER-  
APY SPA on the previous page and this page).  
3. Remove all remaining water from the spa shell. Dry  
the spa shell with towels.  
4. 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.  
5. Set the air control on the console to the highest  
setting and repeat step 3.  
6. Drain the pumps (see DRAINING THE PUMPS on  
this page). Once the water is drained from the  
pumps, place the vacuum nozzle over the drainage  
hole in the pumps and vacuum any additional  
water from the pumps. Note: For additional pro-  
tection, remove the pump/motors from the spa  
and store them in a climate-controlled room.  
7. Clean the spa shell (see page 13).

5. When the spa is empty, close the valve and  
remove the garden hose. Re-attach the cap and  
return the drain hose inside the spa.  
6. Re-attach the access panel.  
9. Shut the power off at the breaker. Label the  
breaker in such a way that the breaker will not  
be turned on accidentally.  
10. Re-attach the access panel and the spa cover.  
7. Refill the spa and treat the water with chemicals  
(see pages 10 and 14).  
REPLACING THE LIGHT BULB  
DRAINING THE PUMPS  
If the underwater light burns out, you will need to  
remove the pump access panel to replace it (see  
ATTACHING AND REMOVING THE ACCESS PANEL  
on page 14). Make sure the spa power is turned off.  
Next, locate the light housing. Turn the light housing  
counterclockwise and remove it from the spa shell.  
After the hydrotherapy spa is drained, the jet pumps  
should also be drained if the spa will be stored for  
more than thirty days or if it may be exposed to freez-  
ing temperatures.  
Turn off the power to  
the spa. To drain the jet  
pumps, remove the

b. The pump may have a foreign object stuck in  
the impeller. Contact our customer service  
department.  
a. Check to see if the filter is in place. Clean the  
filter if it is dirty.  
c. The pump may have a loose wire connection.  
Contact our customer service department.  
b. Check the chemical balance of the water. If the  
pH is incorrect, the sanitizing agents will not  
function properly. See the section on maintain-  
ing the proper pH balance on page 14.  
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 it is 2” to 4” above the bas-  
ket.  
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. 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.  
b. The pump may have a bad bearing. Contact  
our customer service department.  
6. SYMPTOM: THE WATER DOES NOT HEAT  
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 6°F per hour. If you are using the spa  
indoors and the room temperature is main-  
b. 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.
