Installation
Rotation direction of the shaft
The rotation direction of the shaft is marked by an
arrow on the cover of the side channel housing
and by an arrow on the fan guard of the motor.
 WARNING
Danger from interchanging inlet and
pressure line!
Interchanged inlet and pressure lines can lead
to damage to the pump−motor unit and the
system, and as a result of this to serious
injuries!
Make sure that the inlet and the pressure line
cannot be confused when connecting.
Pay attention to the clear marking with the
arrows indicating the delivery direction on the
inlet and discharge connections.
 WARNING
Danger due to vacuum and gauge pressure!
Danger due to escaping media!
During operation, connected pipes and vessels
are vacuumized or pressurized!
Use only mounting elements, connections,
lines, fittings and containers with sufficient
freedom from leaks and strength for the
pressures which occur.
Make sure that the mounting elements and
connections are mounted firmly enough and
leak−free!
CAUTION
If the pumped gases are passed on the
discharge side in a closed pipe system, then it
must be ensured that the pipe system is
adapted to the maximum discharge pressure.
Connect a pressure relief valve upstream if
necessary.
NOTE
Attach pipes/hoses free of mechanical
tensions.
 Support the weight of the pipes/hoses.
4.3.2 Connecting the inlet line
 WARNING
Danger from solid bodies and impurities in
the pump−motor unit!
If solid bodies penetrate into the pump−motor
unit, blades of the impellers can break and
broken pieces can be thrown out.
Install a filter in the inlet line. Replace filter
regularly!
The pumped gases are taken in via the inlet line.
 Connect the inlet line to the inlet connection.
– The inlet connection with the
corresponding muffler is marked by an
arrow pointing into the pump−motor unit.
A If you use an inlet pipe, you can screw it
directly into the muffler.
B If you use an inlet hose, you need a hose
flange available as accessories:
–
Screw the hose flange to the muffler.
– Push the hose onto the hose flange and
secure it with a hose clamp.
– Observe tightening torques ( 12)
4.3.3 Connecting the pressure line
The pumped gases are discharged via the
pressure line.
 Connect the pressure line to the discharge
connection.
–
The discharge connection with the
corresponding muffler is marked by an
arrow pointing out of the pump−motor unit.
A If you use a pressure pipe, you can screw it
directly into the muffler.
B If you use a pressure hose, you need a hose
flange available as accessories:
– Screw the hose flange to the muffler
–
Push the hose onto the hose flange and
secure it with a hose clamp.
–
Observe tightening torques ( 12)
