0.4 - NOTES REGARDING FLUORINATED GASES
• This climate control appliance contains fluorinated gas.
For specific information regarding the type and quantity of gas, refer to the data
plate affixed to the unit.
• The installation, assistance, maintenance and repair of the appliance, must be
performed by a qualified certified technician.
• Product removal and re-cycling operations must be performed by a qualified
certified technician.
• If the system has a leak-detection device installed, the checks for leaks must be
performed at least every 12 months.
• When the unit is checked for leaks, keeping a record of all inspections is highly
recommended.
• Before starting to operate on the appliance, it is necessary to check the zone
surrounding the equipment to make sure there are no dangers of fire nor risks of
combustion.
To repair the refrigerating system, it is necessary to take the following precautions
before starting the intervention on the system.
1. The zone MUST be checked with a specific refrigerating liquids detector before
and during work, so that the technician is aware of potentially flammable
atmospheres.
Make sure the detection device of the leaks is suitable for use with flammable
refrigerants, then that it does not produce sparks and that is adequately sealed
or intrinsically safe.
2. The leakage electronic detectors may need calibration.
If necessary, calibrate them in a zone free of refrigerant.
3. 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 calibrated for the used refrigerant; the appropriate percentage of gas
(maximum 25 %) must be confirmed.
3a. The leakage detection fluids are suitable for most of the refrigerants. The
detergents containing chlorine MUST be avoided.
Danger of corrosion of the copper pipes.
4. If the presence of a leak is suspected, all open flames must be removed.
5. 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.
6. Make sure the area is adequately ventilated before intervening inside the
system; a continuous degree of ventilation must be present.
7. Before any operation, always check that:
• the condensers are unloaded.
The operation must be carried out safely to avoid the risk of producing sparks;
