Installation
5.3 Connecting pipes
a) Vacuum connection at (Fig. 2/A... 4/A).
NotiCe
Material damage resulting from the forces and
torques of the pipes acting on the unit being
too high
Only screw pipes in by hand.
The suction capacity of the vacuum pump is
reduced if the suction pipe is too narrow and/
or too long.
b) The extracted air can be blown off through the
exhaust silencer (ZSZ) at (Fig. 2/Z... 4/Z) or can
led out through a hose or tube line.
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.
Exhaust air may not be reduced
It is not allowed to install shut-off components
in the exhaust lines (max. pressure difference
30 mbar). With the exhaust line connected, it
must be checked regularly for pollution.
5.4 Control and relief valve
The vacuum can be set by turning the control knob
(Fig.. 2/C... 4/C) as shown on the symbol fitted to
the button.
NotiCe
Do not operate without the standard control
and relief valve
If the permissible vacuum is exceeded (see data
plate) the machine may be damaged.
