■ Specic warnings on the R32 refrigerant
The R32 refrigerant:
- is odourless;
- is slightly inammable (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
qualied personnel;
■ R32 refrigerant load
The procedures described below must only be performed by specialised technicians or
qualied 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 qualied 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,
qualied 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 Teon 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.

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 dierent 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 eect
and in particular to current I.E.E. (BS7671) Wiring Regulations
The electrical installation must be equipped with a dierential 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
