Swimming pool Heat Pump

6. Maintenance and Inspection

6.1 Maintenance

To check the water supply device and the releaser often. You should avoid the condition of no water or air enter
into system, or that will influence unit's performance and reliability. You should clear the water filter regularly to
avoid unit's damage by filter's jam.
There should be dry, sanitary and ventilation around the units. To clean the side heating exchanger regularly for
keeping good heating exchanging and saving energy.
To check the operation of every process in the u nit, the operation pressure of the refrigerant system.
You should maintain or change it in time.
To check the power supply and cable connection often, there is abnormal action or bad smell about the electrical
component. If there is, please maintain or change it in time.
Please discharge all water in the water pump and water system lest freeze the water pump or water system.
You should discharge the water at the bottom of water pump if the units will stop for long time. And you
should check the units thoroughly and fill the system with water fully before power on the units again.
