Operating instructions VacuStar L400
Start-up and operation
21
6.3 Switching off
Switch off the VacuStar L400 as follows:

Switch off drive for the VacuStar L400.

Close the shut-off valves (if installed)

Drain the safety tank. Tank may not be under pressure then.
6.4 Inspections to be performed
Lubricating oil inspection Only lubricating oils pursuant to the lubricants specifications
lubricating oil schedule (Tab. 4,
Other oil types on request.
Tab. 5
Check oil level at the inspection glass. Oil level in the oil supply
tank at least to the middle of the oil sight glass. The oil level may
not drop below the bottom mark on the oil inspection glass.
Non-return valve inspection The non-return valve is maintenance-free, but is subject to wear
like all other moving parts. We recommend a visual inspection
every 3 months. In this connection, the non-return valve must be
dismantled, cleaned, freed of deposits and checked for freedom of
motion.
Safety valve inspection The safety valve is no regulating device!
The operational capability must be checked on start-up and
later at weekly intervals.
The safety valve must be secured against misadjustment. Blocking
or manipulating the safety valve can have penal consequences if it
gives rise to an accident. Any warranty claims shall also be
forfeited in such a case.
The nominal opening pressure may not exceed the maximum
permissible final overpressure (refer to rating plate) or the
permissible system pressure, provided the latter is lower.
Functional testing is carried out by actuating the manual ventilation
with the VacuStar L400 running.
Inspection of the ventilating valve
As a matter of principle, a ventilating valve must be installed as
safety element on the VacuStar L400's suction side. When the set
vacuum is reached, the ventilating valve opens and admits
atmospheric auxiliary air into the system. The operational capability
must be checked weekly with the aid of a vacuum meter at the
VacuStar L400's inlet. In case of systems without cell ventilation,
the vacuum may not drop below the permissible value of 200 mbar.
In case of systems with cell ventilation, the vacuum may not drop
below the permissible value of
100 mbar.
