PROBLEMS
POSSIBLE CAUSES
SOLUTIONS
The device won’t start.
No power
No need for heat
Compressor protection delay
activated (Power light is
flashing)
Make sure circuit breaker is on
Check desired temperature and
adjust if necessary
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.
Water intake and outlet have
been reversed
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.
Water connections are reversed
Heat loss is greater than the
devices heating capacity
Pool is too large for the heat
pump model
Check to see if water is circulating
in the right direction toward
condenser.
Choose a more powerful model or
use more than one heat pump.
Choose a more powerful model or
use more than one heat pump.
There is a lot of water under the
device.
Normal runoff due to
condensation
Abnormal water leak.
No action required (install a drain
if necessary)
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.
Outdoor temperature is cold
Compressor works but fan does
not work
The defrost sensor is defective –
alarm
Cooling fluid level is too low
Check to see if defrost is working
(the compressor does not operate
during defrost – only the fan
operates)

Regulator display is hard to read.
The regulator display is exposed
to direct sunlight
Create some shade above the
display to make easier to read.
The fan works, but the compressor
does not.
Defrost in operation (Defrost
indicator lights up)
No action required
