Initial Operation
1. When on vacuum operation connect the suction pipe at (A) or (A
when on pressure operation connect at (B) or (B
Warning – rotating impellor
Do not touch the blower inside through the vacuum or pressure connector
(A, A
, B, B
) due to risk of injure from the rotating impellor!

The blowers may be used by connected pipes only.
Due to the working load the impellor is still rotating some minutes after
switch off. The gas in the equipment should be released due the leakage
of the locking device the impellors may rotate. It can be dangerous also if
the pump is switched off, in case the impellor is hand driven.
2. Initially switch the pump on and check the direction of rotation (O ➝

)).
3. When installed on the application and under the highest possible load
conditions, the pressure differences of the unit may not be higher than
the max. allowable pressure differences shown on the plate (N).
Caution – Overloading of the blower
The pressure differences of the unit may not be higher than the max.
allowable pressure difference. If these values are exceeded when
the unit is running on normal operating temperature damages may
occur to the blower.
Unloading of the unit is required by utilising limitation valve ZUV (additional).
Note
Do not disconnect the electrical supply before the blower has stopped.
Maintenance and Servicing
When maintaining these units and where the situation exits where personnel could be hurt by moving parts or by live electrical parts
the blower must be isolated by totally disconnecting the electrical supply. It is imperative that the unit cannot be restarted during the
maintenance operation.
Do not maintain a blower that is at it's normal operating temperature as there is danger from hot parts.
1. Filter and silencer they are connected from the operator have to be maintained from the operator.
2. Bearings:
The units have bearings that are greased for life and require no maintenance.
At extreme working conditions the bearings may require changing after 20,000 operating hours. Change of the bearings (see pict.
Warning – at the disassembly of the rotor strong magnetic forces will be occur
Persons who react to magnetic forces ( i.e. cardiac pacemaker) shouldn't carrying out this work!
Please be aware that the magnetised rotor does not absorb metal parts or shavings. Metal shavings on the rotor would damage the motor.
Disassembly:
Loosen and remove the assembly screw (61) from the cover. Remove cover (62). Pierce on the ventilator the skin of metal 2 x (63). Remove
ventilator (64) from the shaft with support of an extractor. Remove tolerance ring (65) from shaft. Loosen and remove the assembly screw (66) from
the cover (internal). Remove cover (67). Loosen the grub screw (68) from magnet bracket carrier. Remove magnet bracket carrier from the shaft.
Remove adjusting spring (70). Remove cable clip (71). Remove assembly screw (72) from transmitter plate. Carry transmitter plate (73) to the side.
Loosen and remove screw (74). Dismantle bearing plate (75). Remove ball bearing shim (76). Remove flange (77) complete with rotor (78) from
the stator housing (79). Protect magnet (80) against dust and mechanical damage through winding. Loosen and remove 3 screws (81). Remove
flange (77) from the rotor (78). Remove circlip (82). Remove bearing AS (83) and bearing BS (84) from the rotor with support of an extractor.
