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, you should 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
information 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 2 to 5 hours.
Press the temperature up or temperature down button
on the console. When the display begins to flash,
press the pump 1 button. The display will read F2. To
change the time, press the temp up button until the
desired time is reached. Press the pump 1 button to
confirm the selection. As spa usage increases, the
duration of the filter cycle may need to be increased.
ATTACHING AND REMOVING THE ACCESS PANEL
Turn off the spa power. To remove the indicated
Access Panel (25), Remove the four #10 x 2” Sheet
Metal Screws (46) that secure the Access Panel to
the spa. Carefully remove the Access Panel and set it
aside.
To replace the Access Panel, hold the Access Panel
in place and secure it with the #10 x 2” Sheet Metal
Screws (46). Be careful not to overtighten the
Screws.
DRAINING 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 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.
