Authorised personnel

• The installation, electrical connections, maintenance and repairs of the device

must be carried out by an accredited professional in accordance with the

regulatory texts and the rules of the art in effect in the country where the

device is installed (see § 3.4).

For any intervention on the cooling circuit, the professional must hold a

certificate of competence in handling refrigerants.

For France:

- Low-voltage electrical installation according to NF-C 15-100.

- Legislation on the handling of refrigerants: Decree 2007/737 and its

implementation orders.

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).

• Failure to comply with these recommendations will invalidate the warranty.

Instructions for servicing - maintenance

Maintenance operations must be carried out once per year in order to guarantee

the longevity and the good working condition of the heat pump.

• Maintenance and the different operations must be carried out at the

recommended times and frequencies as specified in this manual.

• Only use genuine spare parts.

• 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.

• 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.
