THE UNIT MUST BE EARTHED PROPERLY BEFORE USAGE OR THE
When installing the heat pump in a small room, make sure it is well ventilated.
● Don't put fingers or objects into the air inlet outlet as the rotating fan could cause serious injuries.
● If you smell anything burning, turn off the manual power switch immediately, stop operation and
contact the after-sale service department. Continued abnormal operation may cause electric shock
fire.
● When the unit needs to be removed or re-installed, please ensure that the work is carried out by
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..
3.1 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.

4.1 Installation Guidelines
4. Installation of the unit

- 10 -
● 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.

●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 absorbers on the surface of the base.

5.1 Attention
● Prevent air, dust and other material from going into the water pipes.
● Fix the whole system before installing the water pipes.
● Water inlet and outlet pipes should be protected by an insulation layer.
5. Installation of pipes

- 15 -
● 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.

●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 lime scale and sand: this kind of water should be filtered and
demineralize.

- 17 -
●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:

6.1 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 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 8 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.
