18. 3 Precautions during refrigerant piping work Take the following precautions on site when connecting pipes Keep in mind that the need to control the entry of moisture and dust is even more important that in conventional piping a Keep the open ends of all pipes sealed until connection with AC equipment is complete b Take special care when doing piping work on rainy days The entering of moisture will degrade the refrigerating machine oil and lead to malfunctions in the equipment c Complete all pipe connections in as short a time as possible If the pipe must be left standing for a long time after removing the seal it must be thoroughly purged with nitrogen or dried with a vacuum pump 10 4 INSTALLATION TRANSFERRING SERVICING 10 4 1 Inspecting Gas Leaks with a Vacuum Pump for New Installations Using New Refrigerant Piping 1 From the viewpoint of protecting the global environment please do not release refrigerant into the atmosphere a Connect the projecting side pin pushing side of the charging hose for the manifold gauge to the service port of the 3 way valve 1 b Fully open the handle Lo of the manifold gauge and run the vacuum pump 2 If the needle of the low pressure gauge instantly reaches vacuum re check step a c Continue the vacuum process for at least 15 minutes then check to make sure the low pressure gauge has reached 0 1 MPa 76 cmHg Once the vacuum process has finished fully close the handle
