Range of application:
1. Power supply: 230V/1N~50Hz.
2. Environment temperature: -7°C〜43°C ：
The power supply to the unit must be grounded.
NOTICE
General Safety
Theheat pump has a anti-freezing operation. In winter when the ambient is below
0℃,the unit will start automatically to keep water from freezing, this protectsthe unit
andwater piping system. DO NOT switch the unit off or disconnect it from the power
supply during low ambient (0°C) times.
If the unit is not in use for extended periodsin winter when the ambient temperature is
below 0℃, theuser can switch off the unit and disconnect it from the power supply,if all
water is discharged from the heat pump and piping system. Failure to discharge water from
the heat pump before switching off or disconnecting the power supply may result in damage
to the unit or piping system.
Please read the below precautions carefully to avoid damage to the unit and/or harm to
the user
The installation, dismantlement and maintenance of the unit
must be performed by qualified personnel. DO NOT make any
changes to the structure of the unit.

- 6 -
Use a dedicated socket outlet / circuit for this unit.
Keep the unit away from other home appliance or heat sources,
this preventsany possible magnetic interferance and ensures
the unit'sperformance.
Do not touch the power plug or any electrical components with
wet hands. Never pull theplug out by pulling on the
power-cable.
Never cover the unit with clothes,plastic or any other material
that may block ventilation of theunit,this will lead to low
efficiency or non-operation of this unit.
Coil fins are sharp and may cut fingers
Never pour water or liquid into or over the unit.

- 7 -
Do not touch the air outlet grill when fan motor is running
Please ensure the power supply is switched off before any
maintenance / cleaning works.
Always select the correct fuse or breaker. Steel wire or copper
wire cannot be used as a substitute for fuse or breaker.
Keep the unit away from combustible or corrosive
environment.
It is mandatory to use a suitable circuit breaker for the heat
pump and make sure the power supply to the heater
corresponds to the specifications.
The minimum inlet water pressure should be 0.1MPa and
maximum pressure 0.7MPa.

How heat Pumps work
Heat pumps transfer heat by circulating refrigerant through a cycle of evaporation and condensation. A
compressor pumps the refrigerant between two heat exchanger coils. In one coil, the refrigerant is
evaporated at low pressure and absorbs heat from its surroundings. The refrigerant is then compressed
en route to the other coil, where it condenses at high pressure. At this point, it releases the heat it
absorbed earlier in the cycle.

●Use the rubber pads provided to absorb shocks and vibration.
Installing The Water Pipes
Refer to the Figure 4.
1. Attention
●Ensure the intended pipework is free from dirt and debris.
● Install / Mount the Heat pump unit before connecting any of the water pipes.
● Water inlet and outlet pipes shall be protected by insulation.
● Stable water flow and velocity shall be ensured, so that excessive throttling can be avoided.
●Never use the water pipes or connections to the unit to move or lift the heat pump.
●Two pipe wrenches must be used when tightening or loosening the inlet and outlet water connections.
3. Hoisting
●Use four or more soft lifting belts to move the unit .
●Use protective plateson the surface of the unit when moving, this will avoid scratches and deformation.
●Check that the mounting structure is suitable before hoisting the unit.
● The heat pump will produce condensate (water),consider drainage when installing the unit.

(5) Heating Time Settings
Press and hold the “ ” button for 3 seconds in the main interface to enable or disable the timed heating
(7) Forced electrical quick heating
The current heating mode is met and the temperature condition for continuing heating is satisfied, without
error "quick heating" may occur.
Press“M” + “∧” button at the same time for more than 5 seconds, the “quick heating” function can be
activated ordeactivated. When the “quick heating” is running, the symbol lights up. If the heat pump is in
cooling mode,“quick heat” is not allowed.
The heat pump needs to be in the working period after the timed control is enabled.
The current heating mode is set and the set defrosting time is not zero and the temperature condition for
defrosting is continued, without error "defrost" may occur.
when the controller is in normal display, press “ ” to switch between cooling or heating mode. When
switchingto the cooling or heating mode, the cooling or heating symbol flashes quickly for 3 seconds and then
returns to the normal display state. When switching to the cooling mode, the temperature adjusts automatically
and selects“manual mode”, and the water temperature can be set at this time. When the cooling/heating mode
isswitched,the compressor will only start running after 3 minutes.
