3. Wiring
Check that the wiring will not be subject to wear, corrosion, excessive
pressure, vibrations, sharp corners or other unfavourable effects of
the environment. The check must also take into account the effects
of ageing or sources of continuous vibrations such as compressors or
fans.
4. Detecting flammable refrigerant fluid
Under no circumstances can a potential ignition source be used to
search for or detect refrigerant fluid leaks. A halide lamp (or any
other detector which uses a naked flame) must not be used.
The following detection methods are deemed acceptable for
refrigerant circuits:
• Electronic leak detectors can be used to detect refrigerant fluid
leaks but, in the case of flammable refrigerant fluids, the
sensitivity may not be adequate, or may require recalibration.
(The detection devices must be recalibrated in a zone without
refrigerant fluid.) Ensure that the detector is not a potential
ignition source and is suitable for the refrigerant fluid used. Leak
detection devices must be set at an LEL percentage of the
refrigerant fluid and must be calibrated for the refrigerant fluid
used, and the appropriate percentage of gas (25% maximum), and
confirmed.
• Leak detection fluids are also appropriate for use with most
refrigerant fluids, but the use of detergents containing chloride
must be avoided as the chloride can react with the refrigerant
fluid and corrode the copper piping.
NOTE: Examples of leak detection fluids
• Bubble method
• Fluorescent agent-based method
If a leak is suspected, all naked flames must be
eliminated/extinguished.
If a refrigerant leak is found, no intervention is allowed. Ventilate the
room until the product is removed.
