●The installation shall be done by the professional persons, to prevent leaking, electric shock, or fire
disaster.
●Confirm the ground connection, if the ground connection is not correctly done, it may cause electric
shock.
●When install the heat pump in a small 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.
Range of application:
1.Power supply: 380-415V/3N~50Hz.
2.Environment temperature: -15°C 〜43°C ：
3.Working water temperature: Min. inlet water temperature 8°C, Max. outlet Water
Temperature 40°C . If the system is always used beyond the available water range,
please contact with manufacturer.
2. Attention for safety

- 6 -
●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.
3.1 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.

●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.

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 installation base.
●Please put shock absorb on base surface.

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

●The one-way valve is suggested for each unit, to prevent the water back flow.
●The system can be combined with multiple units, but should be controlled by each unit
independently.
●Regarding the installation of backup pump, maintenance valve and temperature measure point,
please consider it yourself.
●All pipes and valves of the unit need the heat preservation.

The swimming pool heat pump adopt the titanium heat ex-changer, can connect the swimming pool
directly, but must install a water filtration equipment before water go into heat pump, the filter meshes is
about 40 meshes.

●The pipe press and flow rate should be calculated before the diameter selection, the range of
pressure drop is 0.3〜0.5 kgf/cm2(3〜5m）the range of head pipe flow rate is 1 .2〜2. 5 m/s.

- 13 -
●The hydraulic calculation should be made after the selection of pipe diameter, if the resistance is
more than pump head, then need to choose a more power pump, or choose a bigger pipe.
5.2.4 The demanded quality of water
●The bad quality water will produce more scale and sand, so this kind of water should be filtered and
demineralized.
●The water quality should be analyzed before system running, to measure the PH value,
conductivity, Chloride ion concentration and sulphate ion concentration.
●The acceptable water quality standard is showed as below table.

●Suggest the filter meshes is about 40 meshes.
●Must install the sand filter, hair collector etc. Swimming pool special impurity filter equipment.
6.1 Selection of the water pump
●The circulation pump is needed for the system, the power port is prepared for the pump, (one
phase)
NOTE For the single phase pump, please check the circuitry diagram.
●The head of circulation pump = height difference between water level and main unit + total
pipelines resistance (determined by the hydraulic calculation) + pressure loss of main unit (see the
nameplate on heat pump ).
NOTE
when multi paralleled, the water pump head is subject to the worst working condition loop.
6.2 Selection of the flow switch
●The selection of the flow switch is based on the actual system, the target flow switch is
recommended. Temperature of fluid: 0-120 °C , max working pressure 13.5 bar.
●The flow switch can be installed on the horizontal pipeline or the vertical pipeline which the fluid

flow direction is upward, but should not be installed on the vertical pipeline which the fluid flow
direction is downward.
● The flow switch must be installed on a straight pipeline, there must be more than five times the
length of the pipe diameter at its two sides. And, the direction of fluid must follow the arrow on the
controller. The terminal block should be in an easy operation position, (Figure 10)
●The pannier is absolutely forbid to touch the flow switch floor, or the switch will be deformed and
invalid, (Figure 8)
●Please be sure that the model of target sheet is determined by the system rated flow, diameter of
outlet pipe and the adjustable range of the target(see the user manual). And the target sheet can not
contact the inwall of pipe or other throttlers in pipe, or will cause the switch can not reset.

7.1 Electrical wiring
●The unit should use a dedicated power supply, power supply voltage with rated voltage.
●Unit power supply circuit must be ground, power supply wire and external grounding reliable
connection, and the external grounding is effective.
●Wiring must be constructed by the professional installation technicians in accordance with the
circuit diagram.
7. Installation of electric devices

●Power line and signal line layout should be neat, reasonable, can not interfere with each other, but
not with the connecting pipe and the valve body contact.
●If the unit is not matching the power line, please supply specifications refer to provisions, wires
connecting is not allowed.
●After all wiring construction is completed, please check it before switch on the power supply
carefully.
