any refrigerant leak, it will not
stagnate so as to create a fire or
explosion hazard.
• The appliance shall be stored
so as to prevent mechanical
damage from occurring.
• Check that cabling will not be
subject to wear, corrosion,
excessive pressure, vibration,
sharp edges or any other
adverse environmental effects.
The check shall also take into
account the effects of aging or
continual vibration from sources
such as compressors or fans.
• 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.
• If a leak is suspected, all naked
flames shall be removed/
extinguished.
• If a leakage of refrigerant is
found which requires brazing,
all of the refrigerant shall be
recovered from the system, or
isolated (by means of shut off
valves) in a part of the system
remote from the leak.
• Oxygen free nitrogen (OFN)
shall then be purged through
the system both before and
during the brazing process.
• Before carrying out this
procedure, it is essential that the
technician is completely familiar
with the equipment and all its
detail. It is recommended good
practice that all refrigerants
are recovered safely. Prior
to the task being carried out,
an oil and refrigerant sample
shall be taken in case analysis
is required prior to re-use of
reclaimed refrigerant. It is
essential that electrical power
