9Maintenance
DANGER!
Before undertaking maintenance works:
For maintenance activities, the machine must be secured by withdrawal of the circuit
plug or operation of the main switch to separate it from the E-Grid and to ensure against
re-switch-on.
Pressure-conducting conduits must be purged of air before disassembly! Maintenance
must not be carried out on operation-warm machinery (danger of injury through contact
with hot components)!
All machines of the ZIRKON D003 V to D040 V series have a permanent lubrication for
the bearing. This must not be re-lubricated.
For maintenance operations, the discs and the filter cartridge of the air filter must be
checked, see chapter 9.1 and 9.2.
For maintenance of the filter and discs the exhaust screen and casing lid must be
unscrewed.
For this purpose the fixing screws must be withdrawn and the cover / lid removed.
9.1 Air Filter
NOTICE!
In the case of insufficient maintenance of the filter, the power of the vacuum pump is
reduced!
The filter cartridge for the suction air, depending on the degree of contamination,
should be cleaned by purging from inside to outside.
The operational readiness of the degree of separation will be reduced in spite of
cleaning the filter. Therefore, we recommend replacement of the filter every half
year.
Filter replacement:
Filter replacement is carried out in the following manner:
Unscrew the filter box coverfigure 6, position 3
The filter cartridge is withdrawn, figure 6, position 1
The filter cartridge is cleaned and/or exchanged
