Maintenance and Servicing
When maintaining these units and in other situations where personnel could be hurt by moving parts or by live electrical parts the
pump must be isolated by totally disconnecting the electrical supply. It is imperative that the unit cannot be re-started during the
maintenance operation.
Do not carry out maintenance to a pump that is at its normal operating temperature as there is a danger from hot parts.
Handling of inflammable or aggressive gases and vapours is only possible with special versions, if the safety instructions XE 1 are
noted.
1. Lubrication (picture ᕣ)
The bearings of the blower units need to be greased every 6,000 operating hours on 50 cycles and every 5,000 operating hours on 60 cycles or
at the latest after 2 years with 30 g grease (see 4 greasing points (L)). We recommend Klüber PETAMO GY 193 or other equivalent greases (see
label for recommended grease (M)).
Note! These greasing instruction is valid for operation at 20° C ambient temperature. At 40° C this should be reduced by 50 %.
2. Air filtration (picture ᕤ)
The capacity of the vacuum pump can be reduced if the air inlet filters are not maintained correctly.
These inlet filter cartridges (f) should be cleaned monthly and changed yearly depending on the degree of contamination.
Inlet cartridge cleaning: Remove thumb screws (m). Remove filter cover (d) complete with gasket. Pull filter cartridges (f) off and clean either by
knocking out by hand or by using compressed air. Reassemble in reverse order.
