4.8 Laying suction and discharge line
INFO! Proper layout of the suction and pressure lines directly after the
compressor is integral to the smooth running and vibration
behaviour of the system.
Procedure:
Push Union Nut (5) and Cut Ring (3) onto Pipe (2).
Hand tighten Union Nut (5) until locked.
Insert Pipe (2) firmly into rebate located in Socket (6) ensuring the pipe fits snugly. Tighten
Union Nut (5) 1 ½ turns using a spanner/wrench, while gripping connecting Socket (6) with
another spanner/wrench. This should cause the Cutting Edge (1) of Cut Ring (3) to Cut into
Pipe (2) resulting in a visible collar.
