Installation
5.3 Connecting pipes
a) Vacuum connection at (Fig. 2/A) and pressure
connection at (Fig. 2/B).
NOTICE
Material damage resulting from the forces and
torques of the pipes on the unit being too high
Only screw pipes in by hand.
Long and/or small bore pipework should be
avoided as this tends to reduce the capacity of
the machine.
b) Check to ensure the intake line and pressure line
are connected correctly
NOTICE
Length of the connection pipes
With connection pipes that have the same pipe
cross section as the machine connection and are
more than 3 m long, a non-return valve especially
for the purpose must be installed in order to avoid
reverse operation when the machine has stopped.
5.4 Control and relief valves
The required pressure and vacuum ranges can be
set with the pressure regulating valve (Fig. 2/D) and
the vacuum regulating valve (Fig. 2/C) as shown on
the symbol plate attached to the rotary knob.
NOTICE
Do not operate without the standard control
and relief valves.
If the permissible fi nal compression pressure is
exceeded (see data plate) the machine may be
damaged.
