qualified professionals. If the installation is not correct, it may cause unit operation failure, electric shock,
fire, hurt, leaking, etc.
●Please ensure that any repairs carried out by qualified professionals: failure to make proper repairs
could cause unit operation failure, electric shock, fire, hurt, leaking, etc..
● Do no install the unit near flammable sources, as any leakages could cause a fire.
●Make sure the base on which the unit is installed is strong enough to support it.
●Make sure a leakage protection switch is installed to prevent electric shock or fire.
●When cleaning the unit, stop operation, switch off the power and disconnect the power.

3. Heat pump unit working principle
3.1 Heat pump operation
Heat pumps use heat from the sun by collecting and absorbing energy from the outside air.
This energy is then compressed and transferred to the pool water. Your existing water pump circulates the
water through the heat pump, which is normally installed next to the pool filtration system, and the water warms
up. The heat pump timer can be set so that the pump operates at the times you want: for example, during
daylight hours from 9am to 5pm.
The unit contains a fan that draws in outside air and directs it over the surface of the EVAPORATOR
(energy collector). The liquid refrigerant inside the EVAPORATOR coil absorbs the heat from the outside air
and becomes a gas.
The warm gas inside the coil passes through the COMPRESSOR, which concentrates and increases the
heat to form a very hot gas, which then passes through the CONDENSER (water heat exchanger). It is here
that the heat exchange occurs as the heat from the hot gas is transferred to the cool swimming pool water
circulating through the heat exchanger.
The pool water becomes warmer and the hot gas returns to its liquid form as it flows through the
CONDENSER coil. The gas then passes through the Electronic Expansion Valve and the whole process
begins again.
Developments in heat pump technology mean that today heat pumps can efficiently collect heat from the
outside air even when the temperature is as low as 7-10°C. This means that for tropical and subtropical
climates the pool can be maintained between 26°C and 32°C.

4. Installation of the unit
4.1 Installation Guidelines
● Avoid installations in locations containing mineral oil.
● Avoid installation in locations where the air contains salt or other corrosive gases.
● Avoid installation in locations with serious power supply voltage fluctuation.
● Avoid installation in unstable places, such as a car or cabin.
● Avoid installation near flammable items.
● Avoid installation in locations with strong electromagnetic forces.
● Avoid installation in locations with harsh environmental conditions.
4.2 Installation check
● Check the model, number, name etc, to avoid incorrect installation.
● Make sure there is enough space for installation and maintenance.
●Install in a dry well-ventilated place and make sure there are no obstructions around the air inlet and
outlet.
● Make sure the supporting base is strong enough and prepared to that shocks can be avoided.
● The power supply and diameter of the cables used must 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 put horizontally for at least eight hours before running.

4.6 Lifting
●Please use four or more soft lifting belts to move the sets(see Figure 5).
●Please use protective plates on the surface of the units when handling to avoid scratches and
deformation.
●Double-check that the support base is strong enough before fixing the unit.
● The heat pump will produce condensation water:remember to provide a drainage channel when making
the installation base.
●Please install shock absorber on the surface of the base.

5. Installation of pipelines
5.1 Attention
● Prevent air, dust and other material from going into the water pipes.
● Fix the whole system before installing the water pipes.

- 11 -
● Water inlet and outlet pipes should be protected by an insulation layer.
●Make sure that there is a stable water flow, to prevent excessive throttling.
●Do not handle, move or lift the unit by holding the water inlet and outlet pipe: use only the holes on the
beam of the base (see Figure 5)
● When connecting the water inlet and outlet pipes, use two pipe wrenches to adjust the two parts of the
pipes, and make sure the water inlet and outlet pipes do not twist (see Figure 6).

●It is recommended to install a one-way valve for each unit to prevent water back flow.
●Multiple units can be installed as part of a system, but each unit should be controlled independently.
●All pipes and valves should be insulated.

●The pipe pressure and flow rate should be calculated before selecting the diameter of the pipe, pressure
drop range is 0.3〜0.5 kgf/cm2(3〜5m)head pipe flow rate range is 1 .2〜2. 5 m/s.
●The hydraulic calculation should be made after selecting the pipe diameter. If the resistance is more
than the pump head, then a more powerful pump or larger pipes are required.
5.2.4 Required Water Quality
●Bad quality water will produce more limescale and sand: this kind of water should be filtered and
demineralized.
●The water quality should be analyzed before operating the unit: PH value, conductivity, Chloride ion
concentration and sulphate ion concentration should be checked.
●Acceptable water quality shown below:

6. Installation of optional accessories
6.1 Selection of the water pump
●The circulation pump is required for the system to operate, there is a terminal connection for the pump
(single phase)
NOTE
For single-phase water pumps, please check the wiring diagram.
●Head of circulation pump = height difference between water level and main unit + total pipeline
resistance (determined by the hydraulic calculation) + pressure loss of main unit (see nameplate on heat
pump).
NOTE
Multiple units are installed in parallel place more demand on the water pump requirement.
6.2 Water pipe selection
●The selection of the water pipe should be based on the actual system specifications
●The flow switch can be installed horizontally or vertically. If installed the direction of the water flow must
be upwards and NOT downwards.
● The flow switch must be installed on a straight pipeline, and there must be more than five times the
length of the pipe diameter on either side of the flow switch (see Figure 9 below). The direction of fluid
must follow the arrow on the controller. The terminal block should be installed in a position that is easy to
operate.
