Start-up and operation

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 6 months. In this connection, the non-return valve must be
dismantled, cleaned, freed of deposits and checked for freedom of
motion.
Prior to assembly, the cylinder pin's slide face must be brushed
with Loctite No. 8065 lubricant.
Worn out non-return valves must be replaced!
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.
A maximum pressure pursuant to rating plate is permissible.
Depending on the type of drive, this may according to the table
Technical data on page 17 lower.
Inspection of the ventilating valve
As a matter of principle, a ventilating valve must be installed as
safety element on the VacuStar W'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 W'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.
Inspection of cell ventilation The VacuStar W has been prepared for operation with cell
ventilation. The connection is located at the upper part of the
pressure flange. If your system's cell ventilation is connected, you
may operate the VacuStar W up to a vacuum of 100 mbar. A
suction filter is located in the cell ventilation line. The filter must be
cleaned weekly and replaced in case of visible damage.
