6 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. 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.
7 REMOVAL AND EVACUATION
When breaking into the
refrigerant circuit to make
repairs - or for any other purpose
- con - ventilation procedures
shall be used. However, it is
important that best practice is
followed since flammability is
a consideration. The following
procedure shall be adhered to:
remove refrigerant; purge the
circuit with inert gas; evacuate;
purge again with inert gas; open
