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.

Exhaust pipe
Wiring box

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.

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:

12
from 10 to 35°C.
Keep an adequate distance between the working heat-pump and the resting places.
b. Installation dimensions (mm)

13
c．Installation angle refer to the following diagrams
Pipe connection

14
- Remove vent grid first.
- Install diameter 180mm duct.
- Pressure drops from duct must be lower than or equal to the static pressure of the fan.
- If the pressure drops out of range, the performance of the appliance will be impaired.
Maximum length of the air connection 5m (Diameter of air connection 160 mm).
c. Advised positions
Garage or laundry room (without ducts):
-Unheated room.
-Enables recovery of the free energy released by your vehicle’s engine when switched off after use
or by household appliances in operation.
Laundry room (with one duct):
-Unheated room.
-Enables recovery of the free energy released by your vehicle’s engine when switched off after use
or by household appliances in operation.
-Referring installer menu, adjust the fan speed.

15
Habitable room or outside air (with two ducts):
-Can obtain free heat from the garage.
-If the outside air temperature is low, connection to the outside air may lead to overconsumption
of electricity.
-Referring installer menu, adjust the fan speed
d. Installation caution
When making the connections, you should respect the standards and local directives.
- Before making the connection, rinse the drinking water inlet pipes and water tank exchanger
(HP250CM2),in order not to introduce metal or other particles into the tank.
Select copper pipes for pipeline connection.
- The inlet water pressure is between 0.1~0.5MPa. If lower than 0.1 MPa, a booster pump shall be
added at the water inlet; if higher than 0.5 MPa, a pressure relief valve shall be added at the water
inlet.
- The inlet water temperature is suggested between 10-30°C.
- Outdoor water pipeline and valves should be proper insulated.
- In accordance with safety rules, a safety valve(7bar,99°C,G3/4M) must be installed on the
tank.For France, we recommend hydraulic safety units fitted with a membrane with the NF
marking.
Integrate the safety valve in the cold water circuit.Install the safety valve close to the tank in a
place which is easy to access.
No isolating devices should be located between the safety valve or unit and the tank
The rated pressure of the safety valve shall not exceed 0.7MPa.
- The outlet pipe in the valve or safety assembly must not be blocked.
- The diameter of the safety unit and its connection to the calorifer must be at least equal to the
diameter of the domestic cold water inlet on the calorifer.
- If the mains pressure exceeds 80% of safety valve, a pressure reducer must be installed upstream

16
of the appliance.
.
Do not connect the domestic hot water connection directly to copper pipes in order to prevent
galvanic couples in iron/copper (risk of corrosion). It is compulsory to fit the domestic hot water
connection with a dielectric connection (not supplied).
- Pressure relief valve, thermostatic valve, stop valve, check valve, T&P valve and French
combination valve are not included in the accessories, please select proper fittings in
local market;
- Valves with NF/CE certification are recommended

e. Connection to solar collectors (Version HP250M3C)
WARING: Plumber -Be Aware
Using solar energy, please make sure that the heat pump water tank temperature not more than
85 ℃.

18
f. Connection to gas boiler (Version HP250M3C)

19
WARING: Plumber -Be Aware

more than 85 ℃.
g. Electrical connections precautions
WARNING
- Only qualified professionals may carry out electrical connections, always with the power off.
- The earthing shall comply with local standards.
- Water heaters shall be equipped with a dedicated power line and residual current circuit breakers.
