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.
three-phase models only
- The phases may be
reversed or there may be a loss of phase, 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 Maintain 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:
FAULT-
NO 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:
FAULT-
HIGH REF PRESSURE
Verify circulating pump is on and that there are no water flow
restrictions to the heat pump. If the filter pump is a two speed
or variable speed pump, switch to a higher speed. 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:
FAULT-
LOW REF 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 off 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.
