5. MAINTENANCE
Confirm the followings before pilot run of heat pump
1. The heat pump has been finished well;
2. Assemble pipe and wire are all correct;
3. Drainage of water is provided for
4. Insulation materials are complete;
5. Ground wire is installed well;
6. Power voltage is equivalent to rated voltage of heat pump;
7. Inlet and outlet air port have no obstacle.
8. Any air pocket in the water pipe is expelled,and all valves are opened;
9. Leakage protection device works well.
10. Input water pressure is less than 6 bar for HPW200/300 and 4 bar for HPW150.
Maintenance
Ÿ Frequently check power plug and sockets to make sure both of them have been
connected well and reliably, grounded and have no over-heating effect.
Ÿ When not used for a long time, drain out water filled in the water tank to prevent
damaging inner tank.
Ÿ To ensure heat pump works a long-term and with high efficiency, clean inner tank every
half a year to remove accumulated sediment, observe the following rules while
cleaning the inner tank:
Ÿ Turn off power supply of heat pump.
Ÿ Turn off cold water inlet valve, and open up hot water tap water.
Ÿ Connect drainage water with drain outlet through a pipe.
Ÿ Turn on drainage water port of heat pump, clean water tank attached to inner tank
until it is clear of sediment.
Ÿ
Turn off drainage water port, re-fill water into inner tank and reconnect to power
supply.
Ÿ
Each device has been matched with one anode rod, and anode rod will be slowly
consumed during the process of protecting inner tank and extending use life. Under
some water circumstance, anode rod and water can rise reaction, hot water will be
quickly corroded and rise leakage when anode rod has been used up. It's a rule, check
insulation materials every year, if anode rod is used up, replace with new one
Ÿ Filter should be cleaned up every one month to ensure effective heating.
