Compressor cuts on briefly and then off after
Five minute delay before set point is reached.
Faulty Compressor. Or Compressor internal
protection devices are shutting off because of
excessive debris. Faulty Compressor contactor.
Incorrect wiring. Control Board Failure. Internal
bypass valve damaged or clogged with debris. Heat
exchanger clogged with debris. Suction leak allowing
air into the water flow. Unit is plumbed backwards.
Clean entire filtering system and or replace filter element. Inspect &
clean pump impeller. Adjust all plumbing valves. Repair suction air

accumulating and being drawn back through the outer
air coil. The fan is obstructed, low air flow. Sprinklers
spraying on the outer air coil during cooler
temperatures. Outer air coil clogged with debris.
Plants too close to heater, blocking discharge air flow.
Low refrigerant pressure caused by a Refrigerant
leak. Possible malfunctioning of the internal low
refrigerant pressure switch. Check Alarm Status on
Control Board for LOW REFRIG Alarm.
The outside air temperature too low and Defrost feature is NOT
enable. Malfunctioning Defrost Thermistor. Make sure heater is
installed with the required placement clearances for air flow and roof
clearance. Do NOT install indoors. Make sure that your sprinklers do
NOT spray on the heater in any way what so ever. If ice forms on the
outer coil, shut the heater off and allow ice to thaw. You may use water
at low pressure to thaw ice build up on the outer coil, shut the heater
