■ Specic warnings on the R32 refrigerant

The R32 refrigerant:

- is odourless;

- is slightly inammable (A2L), but only in the presence of ames;

- Risk of explosion at air concentrations between the lower and upper ammability levels of the

uid, see refrigerant data sheet above.

It is essential to follow the following guidelines:

- do not smoke near to the appliance ;

- put up no smoking signs near to the appliance ;

- ensure that it is installed in a well-ventilated area

- do not pierce or burn the appliance ;

- do not position the appliance near to ignition sources, such as naked ames, electric heaters,

etc.;

- any special work or repairs to the appliance must be carried out by specialised technicians or

qualied personnel;

■ R32 refrigerant load

The procedures described below must only be performed by specialised technicians or

qualied personnel:

- ensure that other types de refrigerant do not contaminate the R32;

- keep the gas bottle in a vertical position when loading it;

- put a suitable label on the unit after loading it;

- do not load more refrigerant gas than needed;

- before loading, search for leaks before carrying out an operating test. This operation has two

purposes, to control the quantity of refrigerant loaded and to check the circuit for leaks,

- after the operating test, we recommend carrying out another leak test,

■ Eliminating the R32 refrigerant

Follow the standardised procedures for collecting refrigerants, which may only be carried

out by specialised technicians or qualied personnel, and return it to the supplier.

■ Installation precaution related to the refrigerant

If local construction codes or safety standards don’t exist, the information shown below are

taken from the standard EN378: 2016 may be used for information; they may be used as a guide

for the safe use of machines that use R32 as a refrigerant.

This outdoor unit must not be installed in a place that can the general public or untrained,

qualied or approved persons can access.

It is designed to be installed outdoors, in open air. A shelter or alcove in which at least one of

the longest walls is open to the outside air by louvers having a free area of 75% and covering

8 / 78 00U07362410-A_EN 01.07.2022 9 / 78

at least 80% of the wall (or the equivalent if more than one wall is open to the outside

air), is considered to be open to the outside air.

It must be located so that no refrigerant leaks can enter the building and/or endanger

people and property. Therefore:

It must not be possible for the refrigerant to spill into a ventilation duct, under

a door, hatch or similar opening in case of a leak. For this reason, the installer

must ensure that there is a distance of at least 1m between the unit and any such

opening. When a shelter is provided for the refrigerant appliance in the open air,

this shelter must be equipped with a natural or forced ventilation device.

For refrigerant appliances which are installed outdoors at a location where a

refrigerant release may stagnate, for example, below ground level, the installation

must meet the requirements relative to gas detection and machine room ventilation.

1.2.4. Recommendations for hydraulic and electrical circuits

■Hydraulic connections

The connection must comply with good engineering practices according to the regulations

in force.

Reminder: Make the assembly seals according to good engineering practices in force

for plumbing work:

- Use suitable seals or gaskets (bre seals, O rings).

- Use Teon or hemp tape.

- Use sealant (synthetic as required).

■ Characteristics of the water for the appliance

To ensure that the appliance is working correctly, the water must be ltered correctly

(see the indications at the beginning of this section) and the quantity of dissolved must

be minimised.

Refer to chapter 3.6.4. For further recommendations.

The maximum authorised values are as follows:

Use glycol water if the room where the primary/secondary storage tank(s) is/are installed

If glycol water is used, plan an annual control of the glycol quality. Use monopropylene

type glycol only. The recommended concentration should not exceed 40%.

If glycol is not used, trace the pipes electrically outside.

• In certain installations, the presence of di󰀨erent metals can cause corrosion

problems; in this case, the formation of metal particles and sludge in the

hydraulic circuit is seen.

-Please refer to the chapter “Treatment of domestic and heating water” in our price

catalogue

• It is also necessary to ensure that the treated water does not become aggressive

for the circuit.

■Electrical connections

Ensure that the general electrical power supply has been cut o󰀨 before starting any

repair work.

Characteristics of the electrical power supply

The electrical installation must be conducted in accordance with the regulations in e󰀨ect

and in particular to current I.E.E. (BS7671) Wiring Regulations

The electrical installation must be equipped with a di󰀨erential protection.

This appliance is designed to operate under a nominal voltage of 400 V +/- 10%, 50 Hz.

For installations without neutral, a galvanic isolating transformer must be used that is

earthed on the secondary side.

The electrical connections will only be made when all of the other assembly operations

(attachment, assembly,...) have been carried out.

Never use a socket for the power supply.

CAUTION:

The contract with the energy supplier must cover the maximum electrical requirement of

the installation.

The outdoor unit must be supplied directly (without external switch) by a dedicated line

protected at the start by a dedicated isolator switch. (Seer “Current source” paragraph).
