FILTER
• Check the water inlet and drainage often. The water and air inflow into the system should be
sufficient so that its performance and reliability does not get compromised. You should clean the
pool filter regularly to avoid damage to the unit caused by clogging of the filter.

• The area around the unit should be spacious and well ventilated. Clean the sides of the heat
pump regularly to maintain good heat exchange and to save energy.
• Check if all processes in the unit are operational and pay special attention to the operation
pressure of the refrigerant system.
• Check the power supply and cable connections regularly. Should the unit begin to function
abnormally or should you notice a smell from an electrical component, arrange for timely repair
GND
or replacement.

• Winterizing : make sure to purge all the water from the heat pump and other systems in order to
prevent frost damage.
• You should also purge the water if the unit will not work for an extended period of time. You
should check all parts of the unit thoroughly and completely fill the system with water before
turning it on again afterwards.
