VIII. Maintenance
• Check that the device water inlet is open. It is necessary to avoid low water and air fl ows into the device
because they could worsen its performance and reliability. You have to clean the swimming pool fi lter
regularly to avoid damage to the device as a result of a dirty or blocked fi lter.
• The space around the device has to be dry, clean and well ventilated. Clean the side heat exchanger regularly
in order to maintain good heat exchange performance and save energy.
• The cooling system may only be serviced by certifi ed maintenance engineers.

* Notes: One minute after its activation, the water pump starts measuring the temperature of the input and output water.
If the difference in temperatures is higher than 13ºC for 10 seconds, the electronics will stop the heat pump and the control unit
will display fault PP6; after three minutes the heat pump will start again. If it stops three times in 30 minutes because of fault PP6,
the control unit will display fault EE5. It will be possible to start the heat pump again only after disconnecting and re-connecting the power supply. When
the pump is not operating or the device is in heating mode, the system does not monitor abnormal temperature differences.
