Installation
NOTICE
Property damage due to polluted inlet air!
Particles in the inlet air can damage internal components. This can reduce the
performance of the machine or cause failure of the machine.
Ø
The user has to install appropriate filters before the vacuum connection to
clean the inlet air.
Ø
Clean the pipelines from pollutions and possible welding residues before
connecting them.
An output reduction is noticeable when installed at more than 1000 m above sea level. In this case,
please contact us.
It is possible to install the machine on a firm, plane base without anchoring. When installing on a
substructure we recommend fixing it with flexible buffers.
5.3 Connection of pipes
CAUTION
Risk of injury due to constricted or closed exhaust air opening!
Closed, restricted or covered exhaust air openings can cause too high back
pressure in the machine.
Ø
Never close or constrict the exhaust air openings.
Ø
It is not allowed to install blocking devices (valves) in the air outlet line.
Ø
Maximum permissible back pressure: + 50 mbar
If the back pressures are higher due to the process, please contact us.
Ø
Prevent liquids from accumulating in the exhaust line. In case of rising lines,
install a siphon for collecting the condensate and a suitable discharge valve.
Ø
Regularly check the connected exhaust lines for pollution.
NOTICE
Material damage resulting from too high forces and torques of the pipes
acting on the unit!
If forces and torques during installation and operation are too high, the machine
can be damaged.
Ø
Only screw in pipes by hand.
Ø
If necessary, use flexible connections.
NOTICE
Property damage due to wrong direction of rotation!
Long connecting lines of more than 3 m can cause the reverse rotation of the
machine.
Ø
Do not dismount or change the integrated non-return valve and check it regu-
larly for proper functioning.
a) Remove the covers on the vacuum and exhaust air connection (Fig. 2/A, B).
b) Connect the intake line.
c) The extracted air can be discharged through the exhaust silencer (Fig. 2/B) or conducted away via the
flange and a pipe.
To avoid distorting in the piping system, we recommend using compensators.
d) Check that the maximum back pressure is not exceeded!
The suction capacity of the vacuum pump is reduced if the inlet pipe is too narrow and/or too
long.
