INSTALLATION

Alféa Excellia Duo A.I.

Air/water heat pump split 2 services

Heat pumps & boilers

■Installation and maintenance rules

The appliance must be installed and maintained

by an approved professional in accordance with

current regulations and codes of practice.

• Warning, hydraulic unit should not be installed

in an air current.

■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 aﬀect 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 ﬁttings 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 ﬁtting in

accordance with industry standard practice for

plumbing work:

- Use suitable seals (ﬁbre gasket, O-ring).

- Use Teﬂon or hemp tape.

- Use sealing paste (synthetic depending on the

case).

Use glycol/water mix if the minimum ﬂow

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.

• In some installations, the presence of diﬀerent

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.

• 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 oﬀ.

• Speciﬁcations 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 suﬃcient 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 35).

The electrical installation must be ﬁtted with a 30mA

RCD.

This appliance is designed to operate using a

nominal voltage of 230 V or 400 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 ﬁxed 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.

• Cable glands

To ensure the stability of power (Low Voltage) and

sensor (Extra-Low Voltage) cables, it is essential

that the cable glands are tightened according to the

following recommendations:

gland (PE)

• 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 ﬁrmly onto the

loop created. Insuﬃcient tightening can cause

overheating, leading to breakdown or even ﬁre.

• Connecting to controller boards

- Remove the corresponding connector and make

the connection.

Pre-cabled bundle connector and/or screw connector

• Connecting to spring terminals

- Bare the end of the wire to around 12 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.

 Description of the equipment

►

Deﬁnitions

- 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 signiﬁcant

amounts of current at start-up.

- COP (Coeﬃcient of Performance): This is the

relationship between the energy transmitted to the

heating circuit and consumed electrical energy.

►

Packing

• 1 package: Outdoor unit.

• 1 package: Hydraulic unit and outside temperature

sensor.

►

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.
