Copper pipes Use only copper pipes with the thickness given in table 10 and with minimal impurities Because the surface of the pipe is exposed you should take special care and also take measures such as marking the pipes to make sure they are easily distinguished from other piping materials to prevent mistaken use 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 11 4 INSTALLATION TRANSFERRING SERVICING 11 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 manif
