Instructions on transportation and storage
Functionings & principles
1. During transportation or storage, the heat pump water heater shall be packed in the
undamaged package to avoid damage to appearance and performance of the product;
2. During transportation or storage, the heat pump water heater shall be in the upright
position;
3. Under special conditions, this product may be laid down for a short time/distance as
per indication on the side of the package case. The heat pump water heater, after being
laid down for a certain time, shall be kept at upright position for more than 4 hours before
starting up.
The machine shall be kept in the upright position at any time for the best
performance !
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 introduction
Installation precaution
Keep an adequate distance between the working heat pump and the resting room.
- 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 2 to 35°C.

Installation introduction
Installation caution
When making the connections, you should respect the standards and
local directives.
- Before making the connection, rinse the water inlet pipes, 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(8bar,G1/2F) 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 0.8MPa.
-Never block the outlet of the safety valve or its drain line for any reason.
- The diameter of the safety unit and its connection must be atleast equal to the
diameter of the domestic cold water inlet.
- If the mains pressure exceeds 80% of safety valve, a pressure reducer must be
installed upstream of the appliance.
If the air inlet and outlet of the product are not installed with air ducts,
the air inlet and outlet of the product shall be protected to prevent water
inflow, and the waterproof measures shall reach IPX4 level.

Functions & Protections
Electrical leakage protection
The control system of this machine features an electricity leakage protection function.
Automatic defrosting function
Overload protection
Anti-freezing function
The heat pump starts heating to avoid freezing of the water tank if the temperature in
the water tank is too low.
The default temperature setting is 55°C.

D.
E.
F.
When restarting the machine immediately after shutdown, the system goes into the
protection mode and starts after approximately 3 minutes, which is considered to be
normal.
The defrosting mode is automatically activated if the outdoor temperature is too low
and after the compressor already runs continuously for a certain period.
The working load of the compressor will be heavy if temperature is high in summer. In
order to meet hot water requirements of users and to lengthen service life of the
compressor, this product automatically adjusts the fan speed to ensure reliable
operation of the compressor.
3-minutes protection
When starting the machine after electricity input, the system will start after
approximately 3 minutes ,which is considered to be normal.
