suspension unit installa-
tion
- Mount the top guide holder (1).
Shaft mounting (installation in the shaft opening): Mark drill holes, remove holder, drill holes.
Secure the holder with securing set 1 to the shaft opening. This consists of wood screws and
the appropriate wall plugs or anchor bolt sets.
Pipe mounting: The guide holder (1) is attached to the discharge pipe with a clamp (2). This
has slots which can be used to compensate small tolerance levels. Securing the clamp (2) and
the holder (1) is performed using securing set 2. This consists of four machine bolts, 4 hexa-
gon nuts and 8 washers.
- Align the coupling base (3) vertically to the guide holder (1) on the base. Mark drill holes,
remove coupling base (3) and drill holes.
- Secure the coupling base (3) with securing set 3. This consists of anchor bolts sets. Please
observe the relevant assembly instructions.
If you are using a foundation frame (5) (this can only be used with DN300
and DN500), the frame must already have been set into the foundation.
Securing set 3 then only consists of four hexagon nuts each with one
washer.
- Screw on the guide element (4) on the stud (6) on the coupling base (3).
- Swing the guide element (4) under the guide holder (1) and screw in the stud (7 short) from
the top. It may be necessary to remove the guide holder (1) during this.
- Screw on the cover cap (8) on the top part of the stud (7 short).
When using guide elements that are longer than 6m, a pipe extension
must be installed every 6m.
- The pipe extension (9) is mounted like a top guide holder (1) for pipe securing.
- Screw on the guide element (4) on the stud (6) on the coupling base (3).
- The lower guide element (4) is now swung underneath the guide holder (1) of the pipe exten-
sion (9) and the stud (10 long) is screwed in from the top. If necessary, the guide holder (1) of
the pipe extension (9) may need to be removed again or pushed to the side.
- The top guide element (4) is now screwed onto the top part of the stud (10 long).
- Swing the top guide element (4) under the guide holder (1) and screw in the stud (7 short)
from the top. It may be necessary to remove the guide holder (1) during this.
- Screw on the cover cap (8) on the top part of the stud (7 short).
To prevent contact corrosion, PVC washers can be inserted between the
guide element and the guide holder on these suspension devices.
