4. The leaks electronic detectors may need calibration. If necessary,
calibrate them in a zone free of refrigerant.
5. Make sure the detector is not a potential source of combustion and
that it is suitable for the refrigerant used. The device for detection
must be set at a percentage of the refrigerant LFL and must be cal-
ibrated for the used refrigerant; the appropriate percentage of gas
(maximum 25 %) must be confirmed.
6. If the presence of a leak is suspected, all open flames must be removed.
If a fluid leak which requires brazing is encountered, all refrigerant
must be collected from the system or insulated (by means of shut
off valves) in a part of the system away from the leak. Then, bleed
nitrogen without oxygen (OFN) through the system both before and
after the brazing process.
7. In case it is necessary to carry out a hot work on the appliance, IT
IS NECESSARY to have a powder or CO2 fire extinguisher available.
8. To carry out a work which includes exposition of pipes which
contain or contained a flammable refrigerant, DO NOT use sources
of combustion. Risk of fire or explosion!
9. All sources of combustion (even a lit cigarette) should be kept away
from the place in which all operations during which the flammable
refrigerant may be released in the surrounding space must be carried
out.
10. Make sure the area is adequately ventilated before intervening inside
the system; a continuous degree of ventilation must be present.
11. DO NOT use means different from those recommended by the
manufacturer in order to speed up the defrosting process or for
cleaning.
12. Before any operation, always check that:
• the condensers are unloaded.
The operation must be carried out safely to avoid the risk of pro-
ducing sparks;
• there are no live electrical components and that the cables are
not exposed while loading, recovering or bleeding the system;
• there is continuity in the ground connection.
