    4-1. Installation Work and Servicing Safety There are no special safety precautions for R32. However, like R410a and R22, improper installation and servicing can cause serious accidents. Therefore always observe the following safety warnings. WARNING Since the working pressure is 1.6 times higher than that of refrigerant R22 models, some of the piping and installation and service tools are special.
  • Page 178 CAUTION 2-5.No ignition sources No person carrying out work in relation to a refrigeration system which involves exposing any pipe work that contains or has contained flammable refrigerant shall use any sources of ignition in such a manner that it may lead to the risk of fire or explosion.
  • Page 179 CAUTION 5. Cabling Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges or any other adverse environmental effects. The check shall also take into account the effects of aging or continual vibration from sources such as compressors or fans. 6.
  • Page 180 CAUTION 10. Decommissioning Before carrying out this procedure, it is essential that the technician is completely familiar with the equipment and all its details. It is recommended good practice that all refrigerants are recovered safely. Prior to the task being carried out, an oil and refrigerant sample shall be taken in case analysis is required prior to re-use of reclaimed refrigerant.
