6. Maintenance and Inspection
6.1 Maintenance
•
Check the water supply device and the releaser often. There should always be water entering the
system. The condition air entering the system should be avoided, or it will influence unit's
performance and reliability. You should clear the water filter regularly to avoid damage to the unit
because of a jammed filter.
•
The area around the unit should be dry, sanitary and ventilated. Clean the side of the heating
exchanger regularly to allow proper heating exchange and save energy.
•
Check the operation of every process in the unit, and the pressure of the refrigerant system. You
should maintain it and change it in time.
•
Check the power supply and cable connections often, if there is any abnormal action or a bad smell
coming of the electrical component, please maintain it or change it in time.
•
Please discharge all water in the heat pump and water system to avoid freezing of the heat pump or
water system. You should discharge the water at the bottom of the heat pump if the unit will not be
used for a long time. Check the units thoroughly and fill the entire system with water before
powering the units on again.
