Maintenance and Solution
I. Maintenance
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 temperature 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;(temperature 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
