Page 36 exposing any pipe work shall use any sources of ignition in such a manner that it may lead to the risk of fire or explosion. All possible ignition sources, including cigarette smoking, should be kept sufficiently far away from the site of installation, repairing, removing and disposal, during which refrigerant can possibly be released to the surrounding space.
Page 37 • that capacitors are discharged: this shall be done in a safe manner to avoid possibility of sparking; • that no live electrical components and wiring are exposed while charging, recovering or purging the system; • that there is continuity of earth bonding. lll.
Page 38 Vl. DETECTION OF FLAMMABLE REFRIGERANTS Under no circumstances shall potential sources of ignition be used in the searching for or detection of refrigerant leaks. A halide torch (or any other detector using a naked flame) shall not be used. The following leak detection methods are deemed acceptable for all refrigerant systems.
Page 39 Compressed air or oxygen shall not be used for purging refrigerant systems. For appliances containing flammable refrigerants, other than A2L refrigerants, refrigerants purging shall be achieved by breaking the vacuum in the system with oxygen-free nitrogen and continuing to fill until the working pressure is achieved, then venting to atmosphere, and finally pulling down to a vacuum.
