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.
