Heat Pump Water Heater Installation and Service Manual Model HP200M3 HP250M3 HP250M3C Please read this manual carefully prior to your use of this water heater. The appearance of the water heater given in this manual is for reference only.
1. Product safety statement 1. This appliance can be used by children aged from 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning use of the appliance in a safe way and understand the hazards involved.
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.

2. Evaporator Evaporator effects: it makes the liquid refrigerant absorbs heat and is evaporated into steam. 3. Condenser A condenser: high-temperature high-pressure refrigerant vapor is condensed into liquid, during condensation, the refrigerant vapor discharge heat, the heat is absorbed by the heating medium. 4.

6. High Voltage Switchgear High-voltage switch is to prevent excessive pressure in the system, thus affecting the life of the system components, high-pressure of the high-voltage switch is 2.8MPa. 7. Service valve Service valve is mainly used for filling refrigerant, after removing the nuts, it contains a valve needle, sales staff can vacuum infusion refrigerant from here.
9. Refrigerant Heat pump refrigerant is R134a, ODP value is 0, no damage to the ozone layer. R134a refrigerant cans appearance is as follows: 5. Installation introduction a. Installation precaution - Do not install the water heater in the position where exposed to gas, vapours or dust. - Install the appliance on a flat, solid surface.
