1 Safety precautions
detector will not become a potential source of ignition, and is
applicable to the measured refrigerant. Leak detector shall be set
for the minimum 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.
If you suspect a leak, then remove all the fire from the scene or put
out the fire.
If 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). Before and during the welding, use OFN to
purify the entire system.
Removal and vacuum pumping
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 following best operations that the flammability is already
taken into consideration are the key. You should follow the
following procedures:
• Remove the refrigerant.
• Decontaminate the pipeline by inert gases.
• Evacuation.
