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.

NOTE!
Before and during operation, use an appropriate refrigerant leak detector to
monitor the operation area and make sure the technicians can be well aware of
any potential or actual leakage of inflammable gas. Make sure the leak detecting
device is applicable to inflammable refrigerant. For example, it should be free of
sparks, completely sealed and safe in nature.
See the fol
lowing table for the amount of additional refrigerant.
