WATER CHEMISTRY
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 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. 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.
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, you should test the
pH of the water regularly. To test the water, purchase
a pH test kit at a pool and spa supplier. 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.
CHANGING THE FILTER CYCLE
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 temp up or temp down button on the con-
sole. When the display begins to flash, press the jet
button. The display will read F2. To change the time,
press the temp up button until the desired time is
reached. Press the jet button to confirm the selection.
As spa usage increases, the duration of the filter
cycle may need to be increased.
ATTACHING AND REMOVING ACCESS PANEL
To locate the access panel, refer to the drawing
below. Turn off the power to the spa. To remove the
access panel, first remove the four #10 x 2” Sheet
Metal Screws (7). Remove the Access Panel (2) by
sliding it down and then pulling the bottom away from
the spa. Note: Be careful not to damage the spa
shell as you remove the access panel.
To re-attach the access panel (2), 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
the four #10 x 2” Sheet Metal Screws (7).
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.
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.
