SYMPTOM CORRECTIVE ACTION

Heat pump will not start, no control board display. Breaker or fuse may be tripped. Reset breaker or check

fuse. If heat pump still does not run, call for service.

Heat pump will not start, control board display working. Heat pump may be in delay count down of 5 minutes

Make sure control board thermostat is calling for heater

to come on (check setting on thermostat and temperature

reading.) Make sure heat pump is not in cooling mode.

Heat pump runs but does not heat. Verify cold air is blowing out the top of the heat pump. If

the heat pump has just been installed or if the pool water

has been allowed to cool significantly, it is necessary to

run the heat pump continually for 24-48 hours. If the heat

pump has been in operation for some time, increase the

circulating pump time, or switch the control board to auto

heat function. If heating a spa, verify no air intake stand

pipes are open. If heat pump still does not heat call for

service.

Heat pump does not run and control board displays

LOW H

O FLOW.

Verify circulating pump is on and all necessary valves

are in the correct positions. Verify filter and skimmers

are clean. Check water level in pool. Temporarily turn off

all fountains and water falls that bypass the heat pump

water inlet. If this does not correct the problem, call for

service.

Heat pump does not run and control board display

shows HIGH REFRIGERANT PRESSURE.

Verify circulating pump is on and that there are no

water flow restrictions to the heat pump. Make sure all

necessary valves are open or in the proper positions to

allow proper water flow to the heat pump. Verify filter and

skimmers are clean. Check for water level in the pool.

This condition may also appear if the heat pump has

not been operated for an extended period. To clear the

condition, cycle the heat pump, on and off, up to 3 times.

If this does not correct the problem call, for service.

Heat pump does not run or short cycles and control

board display shows LOW REFRIGERANT PRESSURE.

Check that fan is operating and air is coming out of the

top of the heat pump, while short cycling. If heat pump

does not run at all, call for service.

Heat pump leaking water. Possible heat exchanger or plumbing leak. Turn the

heat pump off, then turn circulating pump on for at least

one hour to see if the water leak stops. If the water leak

stops, normal condensation is occurring. If the water leak

continues, after the heat pump is shut off for at least one

hour, call for service.
