Assembly of the ZIRKON frame sizes D015 V to D040 V can be undertaken on a
stable and secure surface without the need for fixed footings.
We recommend a fixing at the smaller ZIRKON 003 V to D010 V frame sizes. For
assembly on an under-construction we recommend a fixing using elastic rubber
pads.
Vibration of machines of the ZIRKON construction series is minimal.
NOTICE!
For assembly at levels greater than 1000 metres above sea-level, reduced out-
put is noticeable.
In this case, we advise prior advice from the manufacturer.
7.2 Installation
WARNING!
Mortal danger from electrical shocks!
Non-professional handling of electrical components can lead to life-threatening
electric shocks, if undertaken with insufficient experience.
Electrical installations should only be undertaken by qualified personnel
Fused security for the construction should be carried out via the main junc-
tion box.
1. Vacuum line connection, Fig. 4, Pos. 1.
The hose must withstand a pressure of 5 kPa (absolute). The diameter of

see Fig. 4 Pos. 5
CAUTION!
The suction line must not be connected!
With this start-up the suction line must not be connected. With reverse flow of
the vacuum pump and connected suction line, a vacuum can build up that can
lead to damage to the blades and actual fracture of the blades.
2. Suction line connected to position 1 Fig. 4. Notice: If the vacuum pump is
connected to the generator via a conduit in excess of 3 m in length, we rec-
ommend the inclusion of a non-return valve between the pump and the
conduit. This will avoid reverse flow after shutdown.
3. Vacuum-regulating valve (option): The regulation of the vacuum is carried
out by turning the regulation knob; take note of the indicated turning direc-
tion.

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 lubrica-
tion for the bearing. This must not be re-lubricated.
For maintenance operations, the blades and the filter cartridge of the air filter
must be checked, see chapter 9.1 and 9.2.
For maintenance of the filter and blades the exhaust screen and casing lid must
be unscrewed.
For this purpose the fixing screws must be withdrawn and the cover / lid re-
moved.
9.1 Air Filter
CAUTION!
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:
Outlet grilles / Unscrew the housing cover, Fig. 7 item 1,
Remove the cartridge filter, Fig. 8 item 2,
Filter box lid gasket
Reassemble in reverse order.

bon blades that wear out during operation through abrasion. In order to achieve
faultless operation, the blades must be checked for wear at regular intervals.
For this purpose the blades are disassembled:
Outlet grilles / Unscrew the housing cover, Fig. 7Pos. 1,
blades for inspection see, Fig. 8item 3,
Check minimum height and condition of the blades.
The blades must have the following thickness (A):
