Safety instructions (to be followed at any time)

Refrigerant: R134a; When handling product, you should

- No smoking

- Prevent the accumulation of electrostatic charges

- Work in a well ventilated place.

- Avoid contact with the skin and eyes

- Do not inhale the vapours

- Evacuate the hazardous area

- Stop the leakage

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.

Heat pump system components

1. Compressor The compressor is to effect a low-temperature low-pressure evaporator refrigerant vapor sucked and compressed into high temperature and pressure of the superheated vapor, and then discharged to the condenser heat exchanger.

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. Electronic expansion valve: The refrigerant passes through the electric expansion valve, the pressure from the condensing pressure is reduced to the evaporation pressure, part of the refrigerant will evaporate into gas in the throttling process.

5. Filter It’s interior has a filter and desiccant, the desiccant absorbs moisture from the refrigerant, the filter can filter out impurities in the refrigerant.

nuts

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.

8. Fan It forced air through the duct, and then flows through a heat exchanger to improve heat transfer efficiency of the heat exchanger.

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. The surface can support the machine weight and the condensate water can be drained freely.

- Noise due to operating and air flow do not bother neighbors.

- Make sure there is sufficient space left for installation and maintenance.

- There is no strong electromagnetic interference around that may affect control functions.

- There is no sulfur gas or mineral oil existing at the installation place, which may cause corrosion of the machine and the fittings.

- The water pipe for the water heater used at temperatures below 0°C shall not freeze.

- It shall not be set in rooms where a heating system is used so that heating supply to the room will not be affected.

- It shall not be set inside a totally-enclosed space.

- The air taken in must in no event be dusty.

- Install the appliance in a dry, frost-free room.

- Temperature of the ambient air or of the air taken in by the heat pump for optimum running:

from 10 to 35°C.

Keep an adequate distance between the working heat-pump and the resting places.
