Safety precautions
Leakage detection methods
 The leakage detector shall be calibrated in a refrigerant-free area.
 Make sure that the detector is not a potential source of ignition.
 The leakage detector shall be set to the LFL (lower ammability limit).
 The use of detergents containing chlorine shall be avoided for cleaning because the chlorine may react with the
refrigerant and corrode the pipings.
 If leakage is suspected, naked ames shall be removed.
 If a leakage is found while in brazing, the entire refrigerant shall be recovered from the product or isolated (e.g. using
shut-o valves). It shall not be directly released to the environment. Oxygen free nitrogen (OFN) shall be used for purging
the system before and during the brazing process.
 The work area shall be checked with an appropriate refrigerant detector before and during work.
 Ensure that the leakage detector is appropriate for use with ammable refrigerants.
