VI.Maintenance & Repair
● Maintenance
：
1. The motor has been lubricate and sealed in advance before left the factory, therefore
lubricate is not needed during maintenance.
2. Using a stiff nylon brush to clean the evaporator fins. Before scrub, clean it with
vacuum cleaner. If there is compressed air, you can use high pressure air duct to clean
the condenser and evaporator.
3. Periodic inspecting if the air inlet or outlet is stopped up
。
4. Pay more attention to the exhaust/ suction pressure of the system. If there is any
abnormity, find out the reason and clearing the fault. If you cannot determine the
reason, get in touch with the technician.
5. To control and protect the equipment, do not adjust the factory setting freely.
6. Periodic inspect the electrical connections and regularly monitor the operating voltage,
operating current and phase balance. Timely to check the reliability of the electrical
components, replace the expired and unreliable parts timely.
7. Inverter floor heating heat pumps use patent heat exchanger and the outlet water
temperature is high. After long time operation, the heat transfer surface of the water
side heat exchanger will be deposited calcium oxide or any other minerals. If these
minerals fouling too much on the heat transfer surface, it will effect heat transfer
performance
，
So regular cleaning is necessary. Descaling only for life water, the
warm water pipeline is full enclosed type, no need to do descaling. Notice:
Replenishment pipes must increased Y-filter device to prevent condenser or pipeline
blocked; Descaling material: used formic acid, citric acid, and acetic acid etc. clean,
cannot contain cid or fluoride sanitizer, due to water side heat exchanger’s material is
stainless steel, easy to corrosion, lead to refrigerant leak
● Parts replacement
：
When replace the parts, you must use resource.
● System maintenance
：
Whether need to refill the refrigerant depend on the value of exhaust/suction pressure.
The air tight test should be done. in case of leakage or replacements of the
components of the circulate system. In accordance with the following two situations
when refill the refrigerant:
1. The refrigerant leak completely
：
If this happens, you must use 40Kgf/cm
2
r high pressure nitrogen or a small amount of
refrigerant to do leak detection. Before repair welding, the gas in the system must be
drained. Before refill the refrigerant, the system must be thoroughly dried and vacuum.
