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 store
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 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.
REMOVING AND ATTACHING THE ACCESS PANEL
To locate the access panel, refer to the drawing on
page 6. Turn off the power to the spa. 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. Note: Be careful not to
damage the spa shell as you remove the access
panel.
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
the four 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.
