WATER CHEMISTRY cont...
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 corrode the metal parts in the spa jet unit. Also, the
sanitation agents in the water will not be effective if the pH level is not
properly maintained. Damage caused by improper pH levels is not cov-
ered 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 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.

TROUBLESHOOTING
TEMPERATURE SENSOR FAILURE
After a power-up, the display will blink until a key on the control panel
is pressed. This feature is to let the user know that a power failure has
occurred.
Overtemp Mode
OH indicates the water temperature has reached 112 degrees
Fahrenheit ( 44.4 degrees Celcius ). The heater and all output
functions will turn off until water cools to 109 degrees Fahrenheit ( 43
degrees Celcius ). The only functions that will operate during Over-
temp Error will be the Smart Winter Mode and all the keys that do not
start an accessory.
Pressure Switch
The heater is turned off during a FLO error. When pump 1 is on, the
pressure switch is given 5 seconds to close. If, after this delay, the
switch is still open, a FLO error occurs. During this 5 second delay, the
heater can’t be turned on.
To prevent dry run, if the FLO error occurs for more than 0 minutes, the
PUMP 1 or circulation pump will turn OFF. Once in dry run pretection
mode, if any key is pressed, the pump will restart. The error will display
until the flow problem is resolved. When the system detects that the
error message condition no longer exists, it will clear the error itself.
