"Installation

and maintenance regulations

The appliance must be installed and maintained by

an approved professional in accordance with current

regulations and codes of practice.

"Handling

The outdoor unit must not be placed in a horizontal

position during transport.

If not kept upright during transport, the appliance could

be damaged through displacement of the refrigerant

and damage to the compressor suspension.

Any damage caused by transportation in a horizontal

position is not covered by the warranty.

If necessary, the outdoor unit may be tilted only during

manual handling (to go through a door or up a staircase).

This operation must be conducted very carefully and the

appliance must be immediately restored to the upright

position.

"Containment of refrigeration circuits

All refrigeration circuits are sensitive to contamination

from dust and moisture. If any such pollutants penetrate

the refrigeration circuit, they can a󰀨ect the reliability of

the heat pump.

"Make sure that the connections and refrigeration

circuits (hydraulic unit, outdoor unit) are

protected correctly.

"In the event of a subsequent failure and following

an inspection, the presence of moisture or

foreign bodies in the compressor oil would

automatically void the warranty.

- Check upon receipt that the ttings and refrigeration

circuit caps mounted on hydraulic unit and outdoor unit

are properly seated and secured (cannot be loosened

with bare hands). If this is not the case, tighten them

using a C spanner.

- Check also that the refrigeration connections are

sealed (plastic caps or tubes crimped at the ends

and brazed). If the caps must be removed during the

installation (tubes to be re-cut for example), put them

back as soon as possible.

"Hydraulic connections

The connection must comply with industry standard

practice according to current regulations.

Remember: Seal everything when tting in accordance

with industry standard practice for plumbing work:

- Use suitable seals (bre gasket, O-ring).

- Use Teon or hemp tape.

- Use sealing paste (synthetic depending on the case).

Use glycol/water mix if the minimum ow temperature

is set below 10°C. If you are using a glycol/water

mix, arrange for an annual check on the quality of

the glycol. Use monopropylene glycol only. The

recommended concentration is 30% minimum. Never

use monoethylene glycol.

Remember: The presence at installation of a CB-

type disconnection function, for preventing heating

water being returned to the drinking water system, is

required by articles 16.7 and 16.8 of the Local Plumbing

Regulations.

"In some installations, the presence of di󰀨erent

metals can cause corrosion problems; the

formation of metal particles and sludge can

appear in the hydraulic circuit.

"In this case, it is advisable to use a corrosion

inhibitor in the proportions indicated by the

manufacturer.

- Please refer to the chapter "Treatment of domestic

and heating water" in our price catalogue.

"You must also ensure that treated water does

not become corrosive.

"Electrical connections

• Before any maintenance operation, ensure that

the general power supply is switched o󰀨.

• Specications of electricity supply

The electrical installation must be carried out in

accordance with current regulations.

Electrical connections will only be made once all other

installation operations (fastening, assembly, etc.) have

been completed.

"Warning!

The contract signed with the energy provider must

be su󰀩cient not only to cover the heat pump's power

requirements but also the combined sum of all the

appliances likely to be operating at the same time. If the

power is too low, check the power rating stated in your

contract with your energy provider.

Never use a power socket for the power supply.

The heat pump must be supplied directly with power

(without external switch) by special protected leads

from the electric panel via dedicated bipolar circuit

breakers, C curve for the outdoor unit, C curve for

the electrical heating and domestic water backups

(see tables page 37).

The electrical installation must be tted with a 30mA

RCD.

This appliance is designed to operate using a nominal

voltage of 230 V +/- 10%, 50 Hz.

• General remarks on electrical connections

It is essential to maintain neutral-phase polarity when

making electrical connections.

Rigid wires are preferable for xed installations,

particularly in a building.

Tighten the cables using the cable glands to prevent the

feed wires from being accidentally disconnected.

The earth connection and its continuity must be ensured.

• Connecting to screw terminals

"The use of ring, spade or blade terminals or

caps is prohibited.

- Always select wire that complies with current

standards.

- Bare the end of the wire to around 25 mm.

- With round end pliers, form a loop with a diameter

which matches the tightening screws on the terminal.

- Tighten the terminal screw rmly onto the loop created.

Insu󰀩cient tightening can cause overheating, leading

to breakdown or even re.

Pre-cabled bundle connector and/or screw connector

• Connecting to spring terminals

- Bare the end of the wire to around 10 mm.

- Push the spring with a screwdriver so that the wire

enters the cage.

- Slide the wire into the opening provided for this

purpose.

- Remove the screwdriver and then check that the wire

stays gripped by the cage by pulling on it.

Alféa Extensa Duo A.I. Heat Pump

1.1 Packing

• 1 package: Outdoor unit.

• 1 package: Hydraulic unit and outside temperature

sensor.

1.2 Unpacking and supplies

While the courier is still present, carefully check the

general appearance of the appliances and check

that the outdoor unit has not been laid in a horizontal

position.

In the event of a dispute, send any relevant reservations

to the carrier in writing within 48 hours and send a copy

of the letter to Customer Services.

1.3 Denitions

- Split: The heat pump consists of two elements

(an outdoor unit to be installed outdoors and a hydraulic

unit to be installed inside the dwelling).

- Air/water: The surrounding air is the energy source.

This energy is transmitted to the heating circuit water

by the heat pump.

- Inverter: The fan and compressor speeds are

modulated according to the heating requirements.

This technology enables you to save on energy and

operate on a single-phase power supply, whatever

the heat pump's output, by avoiding pulling signicant

amounts of current at start-up.

- COP (Coe󰀩cient of Performance): This is the

relationship between the energy transmitted to the

heating circuit and consumed electrical energy.
