●When install the heat pump in a narrow space (equipment room), must keep well ventilated.
●Don't put finger or sticker into the air inlet or air outlet. Because the internal rotor high-speed operation
may cause injury.
●When an exception happens (burning smell), turn off the manual power switch immediately, stop
operating, and contact with after-sale service department. If continue the abnormal operation, it may
cause electric shock or fire disaster.
●When the unit needs to be removed or re-installed, please entrust after-sale service department and
specialized personnel to do it. If the installation is not well done, it may cause unit operation failure,
electric shock, fire, hurt, leaking, etc.
●Must not be unauthorized reformed, otherwise it may cause electric shock or fire.
●When needs to be repaired, please entrust after-sale service department or a specialized personnel to
implement. If improper repaired, it may cause unit operation failure, electric shock, fire, hurt, leaking, etc.
●Can not install the unit in combustible gas easy-leaking places, once the combustible gas leaks around
the unit, it may cause a fire.
●Confirm if the installation base is strong enough, if it is not strong and has been used for a long time, it
may cause falling and injuries.
●Confirm if leakage protection switch is installed, if don't install a leakage protection switch, may cause
electric shock or fire.
●When cleaning the unit, the operation should be stopped, and power switch should be turned off.

3. Heat pump unit working principle
3.1 Heat pump working process
● First, the low pressure and superheated gas in the evaporator is inhaled into the compressor then
becomes the high temperature and high pressure overheated vapour.
● Second, the overheated vapour is exhausted into the condenser and exchange the heat with the water,
then the refrigerant is condensed and becomes the saturated or over cooling high pressure and high
temperature refrigerant liquid. The water is heated up by heat pump when absorbing the heat energy
which released by the refrigerant.
● Third, the refrigerant liquid releases the pressure by passing the expansion valve, then becomes the
low temperature and low pressure liquid.
● Fourth, the refrigerant liquid flows into the evaporator and absorb the energy from the air, then is
vaporized and became the low pressure and overheated vapour. The refrigerant working repeatedly as
described above, then the water which flows through the condenser is heated up constantly, the
temperature rise and can get the hot water.

4. Installation of the unit
4.1 Installation attention
● Avoid installations in such locations with mineral oil.
● Avoid installation in locations where air contains salt or other corrosive gas.
● Avoid installation in locations with serious power supply voltage fluctuation.
● Avoid installation in an unstable place, such as car or cabin
● Avoid installation near flammable items.
● Avoid installation in locations with strong electromagnetic wave.
● Avoid installation in locations with special harsh environmental conditions.
4.2 Installation check
● Check the model, number, name etc, avoid incorrect installation.
● Make sure enough space for installation and maintenance.
● Make sure barrier-free for air inlet and outlet, also dry ventilated place.
● Make sure the bearing surface can meet the requirement and avoid shocks.
● The power supply and its capacity, wire diameter choice should be in accordance with the electrical
installation requirements.
● Electrical installation must comply with the relevant technical standards of electrical equipment, and
electrical insulation work must be done.
● The unit must be power on for at least eight hours before running and debugging.

4.6 Hoisting attention
● Please use four or more soft lifting belts to move the sets Figure 6.
● Please use protective plate on the surface of the sets when moving, to avoid scratch and deformation.
● Recheck whether the foundation is correct before hoisting the unit.
● The heat pump will produce condensation water,please consider the drainage channel when make the

5. Installation of the pipeline
5.1 Attention
● Prevent air, dust and other sundries from going into the water pipes.
● Fix the whole system before install the water pipes.
● Water inlet and outlet pipes shall be protected by the insulation layer.
● Stable water velocity shall be ensured, so that excessive throttling can be avoid.
● When moving, water inlet and outlet pipe shall not be used for hanging, only the holes on the beam of
the base can be used, please refer to Figure 9
● When connect the water inlet and outlet pipes, two pipe wrenches shall be used to control the two parts
of the pipes, and ensure the water inlet and outlet pipes not turning around, please refer to the Figure 7
● Pipeline anti-freezing in case the environmental temperature drops to 3°C.
