TROUBLESHOOTING
PROBLEMS
POSSIBLE CAUSES
SOLUTIONS
The device won’t start.
1)
No power
2)
No need for heat
3)
Compressor protection
delay activated (Power light is
flashing)
1)
Make sure circuit breaker
is on
2)
Check desired
temperature and adjust if necessary
3)
When the device stops,
the regulator imposes a 3-minute
delay before restarting compressor to
allow for pressure balancing.
The displayed water temperature
rises quickly after the compressor
starts.
1)
Water intake and outlet
have been reversed
1)
Check to see if water is
circulating in the right direction in
the pool water heater.
The device works but the water does
not reach the desired temperature.
1)
Water connections are
reversed
2)
Heat loss is greater than
the devices heating capacity
3)
Pool is too large for the
heat pump model
1)
Check to see if water is
circulating in the right direction
toward condenser.
2)
Choose a more powerful
model or use more than one heat
pump.
3)
Choose a more powerful
model or use more than one heat
pump.
There is a lot of water under the
device.
1)
Normal runoff due to
condensation
2)
Abnormal water leak.
1)
No action required
(install a drain if necessary)
2)
To determine whether
this is a leak, turn off the device until
all condensation runoff has gone. See
if there is still water after 24 to 48
hours.
There is frost on the evaporator.
1)
Outdoor temperature is
cold
2)
Compressor works but
fan does not work
3)
The defrost sensor is
defective – alarm
4)
Cooling fluid level is too
low
1)
Check to see if defrost is
working (the compressor does not
operate during defrost – only the fan
operates)
2)
Call a certified technician
3)
Call a certified technician
4)

Regulator display is hard to read.
1)
The regulator display is
exposed to direct sunlight
1)
Create some shade above
the display to make easier to read.
The fan works, but the compressor
does not.
1)
Defrost in operation
(Defrost indicator lights up)
1) No action required
The fan works, but the compressor
does not work for more than 3 hours.
1)
Compressor is broken, in
thermal protection mode or
connections are loose (Power light is
on)
1)
Call a certified technician
