3. Installation and connection
3.1 Notes
The factory only supplies 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. Install the heat pump above the water level of the swimming pool.
4. Always place the heat pump on a solid foundation and use the included rubber mounts
to avoid vibration and noise.
5. 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 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.

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

- 7 -
3.6 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 (see table below).
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.

3.7 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 (see below).
3. After a few minutes, check whether the air blowing out of the unit is cooler.
4. When you turn off the filter pump , the unit should also turn off automatically, if not adjust
the flow switch.
5. Allow the heat pump and the filter pump to run 24 hours a day until the desired water
temperature is reached. The heat pump will stop running at this point. After this, it will
restart automatically (as long as the filter pump is running) whenever the swimming pool
water temperature drops 2 degrees below the set temperature.
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 to prevent the heat pump of running with inadequate water
flow rate. It will turn on when the pool pump runs and shuts off when the pump shuts off. If the
pool water level is more than 1m above or below the heat pump’s automatic adjustment knob,
your dealer may need to adjust its initial startup.
Time delay:
The heat pump has a 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.
3.8 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.

(1) You should check the water supply system regularly to avoid the air entering the system
and occurrence of low water flow, because it would reduce the performance and reliability of
the heat pump.
(2) Clean your pools and filtration system regularly to avoid the damage of the unit as a result
of a dirty or clogged filter.
(3) You should discharge the water from the bottom of the water pump if the heat pump will
stop running for a long time (specially during the winter season).
(4) On any other moment, you should check if the unit has enough water before the unit starts
to run again.
(5) After the unit is conditioned for the winter season, it is preferred to cover the heat pump
with the special winter heat pump cover.
(6) When the unit is running, there is always a little water discharge under the unit.
