(
Check the cable far wear, corrosion, overvoltage, vibration and check if there are sharp
edges and other adverse effects in the surrounding environment. During the inspection,
the impact of aging or the continuous vibration of the compressor and the fan on it
should be taken into consideration.
,--- -----_
Note: Check the leakage of the refrigerant in an environment where there is no potential
ignition source. No halogen probe (or any other detector that uses an open flame)
should be used.
Leak detection method:
Far systems with refrigerant R32, electronic leak detection instrument is available to
detect and leak detection should not be conducted in environment with refrigerant. Make
sure the leak detector will not become a potential source of ignition, and is applicable to
the measured refrigerant. Leak detector shall be set far the mínimum ignitable fuel
concentration (percentage) of the refrigerant. Calibrate and adjust to proper gas
concentration (no more than 25%) with the used refrigerant.
The fluid used in leak detection is applicable to most refrigerants. But do not use
chloride solvents to prevent the reaction between chlorine and refrigerants and the
corrosion of copper pipeline.
lf you suspect a leak, then remove all the fire from the scene or put out the fire.
lf the location of the leak needs to be welded, then all refrigerants need to be recovered,
or, isolate all refrigerants away from the leak site (using cut-off valve ). Befare and during
the welding, use OFN to purify the entire system.

1.Make sure there is no ignited fire source near the outlet of the vacuum pump and the
ventilation is well.
2.Allow the maintenance and other operations of the refrigeration circuit should be
carried out according to the general procedure, but the fallowing best operations that
the flammability is already taken into consideration are the key. You should fallow the
following procedures:
• Remove the refrigerant.
• Decontaminate the pipeline by inert gases.
• Evacuation.
• Decontaminate the pipeline by inert gases again.
• Cut or weld the pipeline.
3.The refrigerant should be returned to the appropriate storage tank. The system should
be blown with oxygen free nitrogen to ensure safety. This process may need to be
repeated far several times. This operation shall not be carried out using compressed
air or oxygen.
