2.2.9 Warnings concerning flammable refrigerants
Units with mildly flammable refrigerants (A2L), such as R32, shall be installed in accordance with the Euro -
pean standards and regulations and with the local regulations, where applicable.
The information below is provided in accordance with standard IEC 60335-2-40 and its annexes and clauses
(hereinafter “Annex” and “Clause”) and it has been taken from the English version of the standard, which is
the document to be referenced.
(Annex DD.2) Do not use means to accelerate the defrosting process or to clean, other than those recom -
mended by the manufacturer.
The external unit shall be stored in a room without continuously operating ignition sources (for example:
open flames, an operating gas appliance or an operating electric heater).
Do not pierce or burn.
Be aware that refrigerants may not contain an odour.
(Annex DD.3.1) General
Installation shall be implemented in accordance with the European standards and regulations and with the local regulations,
where applicable.
The external unit shall be installed outdoors. Installation indoors or in confined spaces shall in no case be admitted.
The refrigerant charge of the external unit is specified in the unit ID plate.
(Annex DD.3.2) Unventilated areas
The external unit shall be stored in a room with a min. floor area (Amin) suitable for a flammable refrigerant. The min. floor
area “Amin” shall be calculated in accordance with the existing regulations and Clause GG.2 to standard IEC 60335-2-
40. If multiple units are stored in one room, the min. floor area shall be calculated in function of the total number of units
simultaneously stored, therefore considering the total refrigerant charge. The refrigerant charge of each unit is listed in the
technical specification plate affixed on the unit and on its packaging.
The room where units are stored shall be free of open flames or other potential ignition sources (e.g. operating electric
heaters, appliances producing electric arches or surfaces with a temperature exceeding X °C, where X is the surface tem-
perature defined in sect. 22.117 of standard IEC 60335-2-40).
The external unit shall be stored so as to prevent mechanical damage from occurring, as it may cause breakage or refrige-
rant leaks.
(Annex DD.3.3) Qualification of workers
Any operation concerning the installation, maintenance, repair, disassembly and dismantling of the unit shall be carried out
by qualified personnel, in accordance with Annex HH to standard IEC 60335-2-40, who hold a valid certificate in compliance
with the existing standards.
The above-mentioned operations include:
• breaking into the refrigerating circuit;
• opening of sealed components;
• opening of ventilated enclosures.
