4.6 Laying suction and pressure lines
Fig. 13
A rule of thumb:
Always lay the first pipe section starting from the shut-off valve
downwards and
parallel to the drive shaft.
ATTENTION Improperly installed pipes can cause cracks and tears which can
result in a loss of refrigerant

Proper layout of the suction and pressure lines directly after the com-
pressor is integral to the smooth running and vibration behaviour of
the system.

With this intermediate flange it is possible to lay the pressure line directly from
the valve to the left or right.
