and causes condensation. It is normal to
see condensation dripping under the
heater.

Installation & Operation Manual
Corrective Action
Turn the heat pump on.
Unit will automatically restart when the water temperature goes
below the set temperature.
Reset main breaker and restart heat pump.
Backwash and clean filter.
In this case, there may be a delay before restarting.
The compressor will automatically start again a few
minutes until it has stopped three times continuously.
Ask your electrician to verify your heat pump's power
supply by checking over the L1/L2/L3 connections in
the unit's service box.
To check if the water really is a leak, you must stop
the heater and leave the pool pump running for over
5 hours. If water is still coming out of your heater
after this period, call your dealer for service.
Cover your pool as often as possible with solar cover.
Correct the location of the pool heater.
Clean it by running tap water over the coil without additional
nozzle attachment. Do not use pressurized water as it can
damage the coil and void warranty.
Adjust water flow. Check bypass.
