Installation and maintenance conditions
• Do not attempt to install this device by yourself.
• This product was designed exclusively for domestic use and installation
outdoors. The air that escapes from the product must be able to flow freely
and must not be used for other purposes such as heating or cooling a room or
building.
• This swimming pool heat pump unit heats swimming pool water and maintains
a constant temperature; it should not be used for any other purpose.
• Check the power cable. If the power cable is damaged, it has to be replaced
by the manufacturer, its after-sales service or by a qualified and authorised
person.
• Grounding connection of the device and its continuity are mandatory. The
ground wire has to be longer than the other wires in order to prevent the risks
of electric shock in the event the cable is pulled out. The electrical installation
must be equipped with a differential protection of 30 mA (see § 3.4).

by the manufacturer, its after-sales service or by a qualified and authorised
person.
• Verify the grounding connection of the device and its continuity.
• Clean the coil with the help of a soft brush or jet of air or water (Warning,
never use a high pressure cleaner).
• Verify that the drains flow well.
• Verify the tightening of the hydraulic and electrical connections
• Verify the hydraulic sealing of the condenser.
• Have the leak-tightness of the cooling circuit to the leak detector checked by
an accredited professional.
Before any maintenance operation, the heating pump must be
disconnected from any electrical current source. The maintenance
operations must only be carried out by personnel that is qualified and
authorised to handle liquid refrigerants.
Instructions for winterising
• Put the heat pump in “OFF” mode.
• Cut the power supply to the heat pump.
• Empty the condenser with the help of the drain to avoid any risk of
deterioration. (high risk of freezing).
• Close the by-pass valve and unscrew the entry/exit connection unions.
• Eliminate the maximum amount of residual stagnant water from the condenser
with the help of an air gun.
• Close the water entry and exit areas of the heating pump to avoid introducing
foreign bodies.
• Cover the heating pump with a dedicated winterising case.
Any damage caused by poor winterising maintenance will lead to
cancellation of the warranty.

3. INSTALLATION AND CONNECTION
3.1 Functional Diagram
Note: The swimming pool heat pump unit is sold without any treatment or
filtration equipment. The components shown on the diagram are parts to
be supplied by the installation engineer.
3.2 Heat pump
Place the heat pump outdoors and away from any enclosed technical
space.
Choose a location that is preferably sunlit and sheltered from dominant
winds.
The device must be perfectly accessible for later installation and
maintenance work.
Placed under a shelter, the minimum required distances mentioned
below must be respected in order to avoid any risk of air recirculation
and a deficiency in the unit's overall performance.

3. INSTALLATION AND CONNECTION (continued)
Do not position the device directly on the floor because this could
cause problems.
Favour positioning on the ground on anti-vibration studs.
A wall bracket must not be used in conditions that can transmit
vibrations.
Do not install the heat pump on a support that risks intensifying the
unit's vibrations.
Do not install the heat pump anywhere liable to amplify its noise level or
anywhere where its noise could disturb neighbours.
Do not use adhesives: the latter are not considered to be a reliable
means of fastening.
Preferably, install the heat pump on a flat and dissociated cement block.
Set up the unit on the supplied rubber bushing (fastenings and washers
supplied).
Fasten the device, in compliance with the tightening indicated to avoid
any risk of accident or damage to equipment and persons.
Another possibility: install the heat pump on rubber floor supports
using suitable fastenings (not supplied).
x 4
5-7 N.m
The maximum installation distance between the unit and the swimming
pool is 15 metres.
The total length of the piping to and from the unit is 30 metres.
Insulate both the above ground and buried hydraulic piping.
The heat pump must be installed at a minimum distance from the pool
in compliance with NF C 15-100 (3.5 m from the water for France) or in
compliance with installation standards applicable in other countries.
Do not install the heat pump close to a heat source.
For installation in snowy regions we recommend sheltering the machine
to avoid snow accumulating on the evaporator.
