2. Functionings & principles
A low-pressure liquid refrigerant is vaporized in the heat pump's evaporator and passed into the
compressor. As the pressure of the refrigerant increases, so does its temperature. The heated
refrigerant runs through a condenser coil within the storage tank, transferring heat to the water
stored there. As the refrigerant delivers its heat to the water, it cools and condenses, and then
passes through an expansion valve where the pressure is reduced and the cycle starts over.

Installation precautions:
1. Water heaters shall be equipped with a dedicated power line and residual current circuit
breakers. The action current shall not exceed 30 mA;
2. The ground line and the zero line of the power supply shall be separated entirely.
3. Connecting the zero line to the ground line is not allowed.
4. Parameter of the power line: 3 1.5mm² or more.
5. If a power cable is damaged, it shall be replaced by qualified professionals to avoid risks.
6. In the case of places and walls where water may be splashed to, installation height of a power
socket shall not be less than 1.8 m, and it shall be ensured that water would not be splashed on
these places. The socket shall be installed out of children’s reach.
7. The phase line, zero line and ground line inside a power socket used in your home shall be

is activated. Heat-pump and electric heating are activated at the same time.
2. Indication
A. COMF comfort mode : starts the heat-pump to make temperature of the water tank reach the set
level, and performs heat preservation after heating. Heat-pump start is at a priority level.
1) The default temperature for the first start is set at 55 C, which may be adjusted via +
and - . The temperature can be adjusted between 35-75 ; the heat-pump can be heated up to
65 , beyond which the electric heater will be activated.
2) Within an ambient temperature range of 7-35 C, the heat-pump is the first to be started by the
system for heating. The heat-pump will not start if the temperature is out of this range, but the
electric heating will be activated.
B. ECO economy electricity consumption mode : during the economy electricity consumption
period, the heat-pump is activated for hot water supply.
1) Introduction to economy function:
Heating is started in the economy period, and heat preservation, which will not be continued if it is
not in the economy period, is carried out after heating. If heating is not completed within the
economy period, it will be kept on until the set temperature is reached.

Cut off power supply and shut down water inlet valve, then drain the water tank to empty via the
sewage outlet. Please stay away from the sewage outlet if there is hot water inside the water tank
to avoid injury.
3. Replacement of the anode bar
The protective anode equipped for Haier heat-pump water heaters can prolong service life of its
products effectively. The magnesium anode, which shall be replaced in time, shall be checked
typically once every 2 years according to different water qualities.
17
