TROUBLE SHOOTING
IF YOUR HEAT PUMP ISN’T WORKING, CHECK THE FOLLOWING…
•Is the screen of control panel lit?
If not, make sure the electrical wires and cables are correctly connected and the power is on. Ensure any circuit
breaker devices are set to the ON position and press the ON button on your controller. Check your controller
cable is plugged in and is not damaged. If the unit has been shut off or the power has been interrupted the
heater will not restart for a 5-minute period to protect the compressor. Wait 5 minutes before attempting a
restart.
•Is there enough water flow?
If the screen displays a water flow related error check the water flow. Is the water pump in operation and the
system free of debris that may cause a blockage? Disconnect pool cleaners to ensure proper water flow.
•Is the current pool/spa water temperature higher than the set temperature on the controller?
If so the unit will not operate until the pool/spa water temperature falls below the set temperature on the
controller.
•Is your heat pump set to run at the correct time and date?
Please check your current timing or temperature modes on your controller –you may have programmed the unit
to turn on at a different time.
•Does your heat pump have an error message on the screen?
If yes, refer to the error code table 19.
IF YOUR HEAT PUMP IS RUNNING BUT NO HEATING, CHECK THE FOLLOWING…
•Is the fan functioning?
If not contact EvoHeat tech support on 1300 859 933
•Is the air discharged from the top of the fan noticeably cooler than the ambient temperature?
If not, check the refrigerant gauge on the bottom panel of the heater. Another way to determine if the
heater is working correctly is to look at the controller’s screen and check to see if the WATER OUT temp is
higher than the WATER IN temp. Check also the INLET WATER TEMP is lower than the HEAT TEMP set point.
If the gauge shows less than 0.8MPA contact EvoHeat tech support to check the refrigerant system.

(Note: can vary based on ambient temperature)
(loss of refrigerant)
CS Owner’s Manual Updated: Dec 2019 Page: 18
•Ensure sufficient fresh airflow around the unit as per installation instructions.
Make sure cold air discharged does not recycle back through the heater. Check the condenser fins. If they
are dirty or blocked use a low flow garden hose only (Pressurised water may cause damage to the heater).
•The unit will periodically defrost when the ambient air temperature is lower than 8 degrees C.
IF YOUR HEAT PUMP IS RUNNING CONTINUOUSLY, CHECK THE FOLLOWING…
•Check the set temperature is at your desired level and that the pool water temperature is at or below this
set point.
•Alternatively, this could be a possible electrical component failure –contact EvoHeat tech support on 1300
859 933
IF YOUR HEAT PUMP HAS WATER APPEARING AROUND THE BASE OF THE UNIT, CHECK THE FOLLOWING…
The water appearing around the base of your heat pump could be condensation or a possible water leak. To
determine, check the following:
•Check the discharge for the presence of chlorine.
If the water has no chlorine then it is condensation and is it normal –see drainage and condensation for more
information. If the water has chlorine, it is a water leak and you need to contact EvoHeat tech support on 1300
859 933. Or…
•Turn the heater off and run the water pump continuously for a period of 2-4 hours.
If the water dries out, then it was condensation –see drainage and condensation for more information. If there
is a continuous leak contact EvoHeat tech support on 1300 859 933.
DRAINAGE & CONDENSATION
Whilst the heater is operating, water in the air condenses on the fins of the evaporator. In the instance of high
humidity, the condensate may be several litres per hour. This may give the impression that the heater is leaking,
however this is a normal function of heat pumps.
The heater will automatically activate reverse cycle or de-icing mode when required which also increases condensate
discharge. This normally occurs at temperatures below 8°C. The condensate water will discharge through the base of
the heater. As an option a pipe can be connected to the drain on the base of the unit to direct condensate water to
an appropriate location.
NOTE: A quick way to verify that the water is condensation is to shut off the unit and keep the pool pump running. If
the water stops running out of the basepan, it is condensation. AN EVEN QUICKER WAY IS to TEST THE DRAIN WATER
FOR CHLORINE –if the is no chlorine present, then it’s condensation.
