TROUBLESHOOTING CHECKLIST
1. Check to be sure that the electrical power is on. Reset the breakers or replace fuses if necessary.
2. Check to be sure the electronic control panel is set properly. The unit must be in either the Pool or Spa
mode and the desired temperature must be set above the actual pool or spa temperature for the heater to
run. If an error code is displayed, reference the table below to determine the cause.
3. Check to make sure the evaporator coil has enough clearance and that there are no restrictions to its
airflow.
4. Certain ambient air conditions may cause the heater to go into defrost mode. The Defrost mode will be
indicated by the Defrost LED.
NOTE: IT IS NORMAL FOR WATER TO DRIP FROM THE DRAINHOLES AT THE BASE OF THE HEATER.
THE UNIT PRODUCES CONDENSATE WHEN IT OPERATES.
The following table lists error codes as they would appear on the electronic control display. In the event
that an error does occur, check the possible causes list for the corresponding error to correct the problem.
