MAINTENANCE TIMER
OPTION
Pump Purge Delay Option
An electronic pump purge option is available for this pool
heater. During extended periods of inactivity during which
pumping may have been turned off to conserve energy, air can
become entrapped in the piping. The pump purge option
delays pool heater operation until the pump has been on for
sufficient time to remove air from piping. Both the inactivity
time and pump purging time are adjustable.
The inactive timer is adjustable from 1 - 99 hours. Selection
of a time between 4 - 8 hours is recommended.
The purge timer is adjustable from 1 - 60 minutes. Selection
of a time between 10 to 30 minutes is recommended.
An override toggle switch is provided to turn off the pump
purge feature for testing or should the option no longer be
desired. When turned off, the call for heat will not be delayed.
Service Indicator Option
A service indicator option is available for this pool heater. The
Service Indicator light on the Diagnostic Information Panel
will light up indicating that the pre-programmed hours/cycles
have elapsed. Contact a qualified serviceperson to perform
service on the pool heater.
