    5. EQUIPMENT Some standard tools and equipment can be used safely with HCs, including gauge manifold sets. Standard vacuum pumps can be safely used after having checked that the only potential source of ignition is the on/off switch and providing they’re used according to procedures listed herein (see Safety Procedure for HC refrigerants). HCs discharged by the pump are usually safely dispersed and do not result in a flammable zone providing the pump is located in a well-ventilated area.
  • Page 16 Ensure the area is well ventilated. Un-brazing and brazing connections Before un-brazing connections, follow one the procedure below. Remove HC from both sides of the system. Where solenoid valves are fitted, ensure they are open, for example by uing a magnet. Wear gloves and goggles when brazing / un brazing.

The requested maintenance interventions are: ▪ lubricant replacement after approx. 100 working hours from the initial compressor start to remove impurities remained in the system and collected in the crankcase from refrigerant and lubricant flow.

  • Page 67: Supplementary Maintenance

    The level at which the lubricant settles during compressor working is highly influenced by the discharge ratio and therefore by the working temperatures. Considering that the acceptable minimum level is 1/4 of oil sight glass, the maximum level has not to be higher than 3/4 of the sight glass, as illustrated in figure behind.
