3. Installation and connection
3.1 Notes
The factory supplies only the heat pump. All other components, including a bypass if necessary, must be provided
by the user or the installer.
Attention:
Please observe the following rules when installing the heat pump:
1. Any addition of chemicals must take place in the piping located downstream from the heat pump.
2. Install a bypass if the water flow from the swimming pool pump is more than 20% greater than the
allowable flow through the heat exchanger of the heat pump.
3. Always place the heat pump on a solid foundation and use the included rubber mounts to avoid vibration
and noise.
4. Always hold the heat pump upright. If the unit has been held at an angle, wait at least 24 hours before
starting the heat pump.
3.2 Heat pump location
The unit will work properly in any desired location as long as the following three items are present:
1. Fresh air – 2. Electricity – 3. Swimming pool filters
The unit may be installed in virtually any outdoor location as long as the specified minimum distances to other
objects are maintained (see drawing below). Please consult your installer for installation with an indoor pool.
Installation in a windy location does not present any problem at all, unlike the situation with a gas heater (including

12
pilot flame problems).
ATTENTION: Never install the unit in a closed room with a limited air volume in which the air expelled from the unit
will be reused, or close to shrubbery that could block the air inlet. Such locations impair the continuous supply of
fresh air, resulting in reduced efficiency and possibly preventing sufficient heat output.
See the drawing below for minimum dimensions.
3.3 Distance from your swimming pool
The heat pump is normally installed within a perimeter area extending 7.5 m from the swimming pool. The greater
the distance from the pool, the greater the heat loss in the pipes. As the pipes are mostly underground, the heat
loss is low for distances up to 30 m (15 m from and to the pump; 30 m in total) unless the ground is wet or the
groundwater level is high. A rough estimate of the heat loss per 30 m is 0.6 kWh (2,000 BTU) for every 5 ºC
difference between the water temperature in the pool and the temperature of the soil surrounding the pipe. This
increases the operating time by 3% to 5%.
3.4 Check-valve installation
Note: If automatic dosing equipment for chlorine and acidity (pH) is used, it is essential to protect the heat pump
against excessively high chemical concentrations which may corrode the heat exchanger. For this reason, equipment
of this sort must always be fitted in the piping on the downstream side of the heat pump, and it is recommended to
install a check-valve to prevent reverse flow in the absence of water circulation.
Damage to the heat pump caused by failure to observe this instruction is not covered by the warranty.

13
3.5 Typical arrangement
Note: This arrangement is only an illustrative example.
3.6 Adjusting the bypass
How to get the optimum water flow:
Please turn on the heat pump under heating function, firstly close the by-pass then open it slowly to start the heat
pump (the machine can't start running when the water flow is insufficient).
Continue to adjust the by-pass, at the meantime to check the Inlet water temp. & Outlet water temp., it will be
Out In
Heat Pump
Use the following procedure to adjust
the bypass:
1.Valve 1 wide open. Valve 2 &
valve 3 closed.
2.Slowly open valve 2 & valve 3 by
half, then close the valve 1 slowly
to increase the water flow to valve 2
& valve 3.
3. If it shows ‘ON’or ‘EE3’on
display, it means the water flow into
heat pump is not enough, then you
need adjust the valves to increase
the water flow through the heat
pump.
To pool

14
optimum when the difference is around 2 degree.
3.7 Electrical connection
Note: Although the heat pump is electrically isolated from the rest of the swimming pool system, this only
prevents the flow of electrical current to or from the water in the pool. Earthing is still required for protection
against short-circuits inside the unit. Always provide a good earth connection.
Before connecting the unit, verify that the supply voltage matches the operating voltage of the heat pump.
It is recommended to connect the heat pump to a circuit with its own fuse or circuit breaker (slow type; curve D)
and to use adequate wiring.
Connect the electrical wires to the terminal block marked ‘ POWER SUPPLY ’.
A second terminal block marked ‘WATER PUMP ’ is located next to the first one. The filter pump (max. 5 A / 240 V)
can be connected to the second terminal block here. This allows the filter pump operation to be controlled by the
heat pump.
Note: In the case of three-phase models, swapping two phases may cause the electric motors to run in the reverse
direction, which can lead to damage. For this reason, the unit has a built-in protective device that breaks the circuit
if the connection is not correct. If the red LED above this safety device lights up, you must swap the connections of
two of the phase wires.
3.8 Initial operation
Note: In order to heat the water in the pool (or hot tub), the filter pump must be running to cause the water to
circulate through the heat pump. The heat pump will not start up if the water is not circulating.
After all connections have been made and checked, carry out the following procedure:
1. Switch on the filter pump. Check for leaks and verify that water is flowing from and to the swimming pool.
2. Connect power to the heat pump and press the On/Off button on the electronic control panel. The unit will
start up after the time delay expires .
3. After a few minutes, check whether the air blowing out of the unit is cooler.
4. When turn off the filter pump , the unit should also turn off automatically , if not, then adjust the flow switch.
Depending on the initial temperature of the water in the swimming pool and the air temperature, it may take
several days to heat the water to the desired temperature. A good swimming pool cover can dramatically reduce
the required length of time.
Water Flow Switch:
It is equipped with a flow switch for protecting the HP unit running with adequate water flow rate .It will turn on wh
en the pool pump runs and shut it off when the pump shuts off. If the pool water level higher than 1 m above or b
elow the heat pump’s automatic adjustment knob, your dealer may need to adjust its initial startup.
Time delay - The heat pump has a built-in 3-minute start-up delay to protect the circuitry and avoid excessive
contact wear. The unit will restart automatically after this time delay expires. Even a brief power interruption will
trigger this time delay and prevent the unit from restarting immediately. Additional power interruptions during this
delay period do not affect the 3-minute duration of the delay.
3.9 Condensation
The air drawn into the heat pump is strongly cooled by the operation of the heat pump for heating the pool water,
which may cause condensation on the fins of the evaporator. The amount of condensation may be as much as
several litres per hour at high relative humidity. This is sometimes mistakenly regarded as a water leak.

3.10 Operating modes for optimal use
- POWER: Used primarily at the beginning of the season because this mode allows very rapid temperature rise
- SMART: The heat pump has completed its primary task, in this mode; the heat pump is in a position to maintain
the pool water in an energy efficient manner. By automatically adjusting speed of compressor and fan the heat
pump delivers a better return.
- SILENT: In the summer months when the heat output is minimal required, the heat pump in this mode is even
more profitable. Added benefit; when the heat pump heats. It goes with minimal noise load.
