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. 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.Freshair – 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.
3.6 Adjusting the bypass
Optimal operation of the heat pump occurs when the cooling gas pressure is 22 ±2 bar.
This pressure can be read on the pressure gauge next to the control heat pump panel. Under these
conditions the water flow through the unit is also optimal.
Note: Operation without a bypass or with improper bypass adjustment may result in sub-optimal
heat pump operation and possibly damage to the heat pump, which renders the warranty null and
void.
Out In
Heat Pump
Use the following procedure to adjust the
bypass:
•fully open all three valves
•slowly close valve 1 until the
water pressure is increased by
approximately 100 to 200 g
•Close valve 3 approximately
half-way to adjust the gas
pressure in the cooling system
•If the display shows "ON" or
error code EE3, close step by
step the valve 2, to increase
water flow and stop when the
code disappear.

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 (see table below).
For horizontal models (Hydro Pro7, 10, 13 and 18): remove the panel to the right of the fan opening.
(Hydro Pro 5: remove the top panel).
For vertical models (Hydro-Pro22, 22T and 26T): remove the corner panel with the electronic control panel.
Connect the electrical wires to the terminal block marked ‘ POWER SUPPLY ’.
Asecond 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 (see below).
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.
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 degree 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 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 higher than 1
m 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 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.
