3. Installation and connection
3.1 Notes
Factory supplies only the heat pump itself. 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 dosing of chemicals must take place in the piping located downstream from the heat pump.
2. Install a bypass in all installations.
3. Always place the heat pump on a solid foundation and use the included rubber mounts to avoidvibration
and noise.
4. Always keep 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
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

9
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.
3.5 Typical arrangement
Note: This arrangement is only an illustrative example.

10
Heat Pump
In
Out
From pool
To pool
Use the following procedure to adjust the
bypass:
1. Open Valve 1 & 2 half way.
2. Close valve 2 until controlshows
NO Or EE3 screen.
3.
Slowly open Valve 2 until pool
Temp shows on screen.
4.
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.
Must not have Valves open Full.
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 heat pump 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
optimum when the difference is around 2 degrees.
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 and to use the appropriate
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.
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.
3. After a few minutes, check whether the air blowing out of the unit is cooler.

11
4. When the filter pump is turned off, 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
when the pool pump runs and shut it off when the pump shuts off. If the pool water level is higher than 1 m above
or below the heat pump’s automatic adjustment knob, your dealer may need to adjust its initial start-up.
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 cooled by the operation of the heat pump to heat 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 for 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 higher efficiency.
SILENT: In the summer months when the heat output is minimal required, the heat pump in this mode is even more
economic. Added benefit; when the heat pump heats. It does so with minimal noise.

NOTE:
(1) Above electrical wiring diagram for your reference.
(2) The swimming pool heat pump must be connected earthed, although the unit heat exchanger is electrically
isolated from the rest of the unit. Grounding the unit is still required to protect against short circuits inside the unit.
Bonding is also required.
(3) It is recommended that your pool filtration pump and your heat pump are wired independently.
Disconnect: A disconnect means (circuit breaker, fused or un-fused switch) should be located within sight of and
readily accessible from the unit. This is common practice on commercial and residential heat pumps. It prevents
remotely-energizing unattended equipment and permits turning off power at the unit, while the unit is being
serviced.
