WATER CHEMISTRY
Maintaining the pH level of the water 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.
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.
2. Never mix different chemicals.
3. Do not exceed the recommended amounts of
chemicals—follow the directions on the label.
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 chemicals—always add
the chemicals to the water as directed.
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.
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.
SANITIZING THE HYDROTHERAPY SPA
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 spa will filter the water every 12 hours. The dura-
tion of the cycle can be adjusted to last for 2, 4, 6, or
8 hours or to run indefinitely. Press the temperature
up or temperature down button on the console. When
the display begins to flash, press pump button 1. The
display will read “F2.” To change the time, press the
temperature up button until the desired time is
reached. Press pump button 2 to confirm the selec-
tion.
Pump 2 purges for five minutes and the blower
purges for 30 seconds at the beginning of each filter
cycle. Pump 1 will run on low during filtration and the
ozone generator will be enabled.
As spa usage increases, the duration of the filter
cycle may need to be increased.
