SAFETY INSTRUCTIONS
14
• When mechanical connectors are reused indoors, sealing parts
shall be renewed. When flared joints are reused indoors, the
flare part shall be re-fabricated.
• Periodic(more than once/year) cleaning of the dust or salt
particles stuck on the heat exchangers by using water.
• Keep any required ventilation openings clear of obstruction.
Repair
• Detection of flammable refrigerants
Under no circumstances shall potential sources of ignition be
used in the searching for or detection of refrigerant leaks.
A halide torch (or any other detector using a naked flame) shall
not be used.
• Leak detection methods
The following leak detection methods are deemed acceptable
for systems containing flammable refrigerants.
Electronic leak detectors shall be used to detect flammable
refrigerants, but the sensitivity may not be adequate, or may
need re-calibration. (Detection equipment shall be calibrated in
a refrigerant-free area.) Ensure that the detector is not a
potential source of ignition and is suitable for the refrigerant
used.
Leak detection equipment shall be set at a percentage of the
LFL of the refrigerant and shall be calibrated to the refrigerant
employed and the appropriate percentage of gas (25 %
maximum) is confirmed.
Leak detection fluids are suitable for use with most
refrigerants but the use of detergents containing chlorine shall
be avoided as the chlorine may react with the refrigerant and
corrode the copper pipe-work.
