Heat Pump Water Heater
1). Frequently check power plug and sockets and make sure both of them have been
connected well and reliably, and have no over-heating effect;
2). When not used for a long time, especially where temp. is below 0℃，water filled
in the water tank must be drained out to prevent from damaging inner tank;
(Operation shown the above contents)
3). To make heat pump to keep a long-term and high efficiency working state, we
suggest you should clean inner tank up every half a year to remove accumulated
sediment, please obey the following rules to clean inner tank:
(1). Turn off power supply of heat pump;
(2). Turn off cold water inlet valve, and open up hot water tap water;
(3) Connect drainage water with drain outlet through a soft pipe;(temp. resist of
drainage pip is less than 93℃， if drainage pipe do not meet demands, please turn on
cold water inlet valve, and turn on hot water tap water until water is not hot);
(4). Turn on drainage water port of heat pump, clean water tank attached to inner
tank up, if needed, you will wash inner tank for many times to clear sediment;
(5). Turn off drainage water port, re-fill water into inner tank and recover power
supply;
4). 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. We suggest
