VacuStar W900 / W1300 / W1600
Start-up and operation
22
Inspections during operation The following inspections have to be carried out during operation:

Prior to every start-up and during operation, the oil level and the
coolant level must be checked and topped up if necessary.

Open shut-off devices. Always turn the four-way cock until it hits
the stop. Intermediate positions are not permitted

Switch on drive and check whether pressure or vacuum are
created.

Pay attention to abnormal noises and leaks during operation. If
necessary, switch off VacuStar W.

Drain condensate at the condensate and safety traps. Vessel
may not be in a state of vacuum when condensate is drained.
Checking the operating data:
 The speed must be between 1000…1,500 min
-1

The cooling water outlet temperature (return flow to radiator)
may be max. 60 °C.

Check positive working pressure at the pressure gauge
(permissible pressure refer to rating plate).

Check the operating vacuum at the vacuum meter (permissible
vacuum refer to rating plate).

The compression end temperature at 20 °C suction temperature
may not exceed the following values:

140 °C at 400 mbar operating vacuum

120 °C at 0.5 mbar excess pressure
If potentially explosive gases and gas mixtures are conveyed, the
following points must be observed:

Prior to every VacuStar W start and during operation:
- Check coolant
- Check oil level
- Check for leaks

Listen for abnormal noise during the suction process. Switch off
the VacuStar W if necessary.

Check the VacuStar W at regular intervals (daily) for signs of
overheating and exceptional deformations. If necessary, switch
off the VacuStar W or do not put it into operation.

Regularly examine the VacuStar W for leaks such as leaking oil
or water or escaping gas. If necessary, switch off VacuStar W
or do not put into operation.

If the VacuStar W is extremely hot: Switch off VacuStar W and
only switch on again after approximately half an hour, to
prevent the rotor from starting.
