Connection from the rear (drawing A+B)
Perform the following steps for the casing:
1. Tilt the plate in the fresh air hole (1) in the rear of the casing outwards.
2. Mount the connecting pipe without gasket (2) in the rear of the casing so that the pipe's collar is
located outside of the casing.
3. Place the pipe with gasket (3) up against the rear of the casing, with the pipe facing outwards so that
the collar is above the collar of the previously mounted pipe, and so that the pre-drilled holes in the
pipe and casing are located above one another.
4. Screw the pipe in place using the three enclosed self-tapping screws (4).
5. Attach the flexi-hose (5) to the connector bush (3) and fasten with the clamp (6). Pull the insulation
sleeve (7) over the flexi-hose.
Perform the following steps for the insert:
6. Break off the pre-cut round plate (9) in the middle of the automatic cassette cover (10).
7. Attach the connector bush (11) to the automatic cassette cover (10) using three self-tapping screws
(12).
8. Fasten the cover (10) to the automatic cassette (13) using two self-tapping screws (14), one on either
side of the cover.
9. When the casing (8) has been mounted, push the insert (15) into the casing so that the pipe (11) on
the insert goes evenly into the pipe (2) on the inside of the casing.
Connection from the bottom (drawing C)
Perform the following steps for the casing:
1. Break off the pre-cut round plate (1) in the bottom plate.
2. Attach the gasket (2) to the connector bush collar (3).
3. Push the flexi-hose (4) through the hole (1) in the bottom plate.
4. Attach the flexi-hose (4) to the connector bush (3) and fasten with the clamp (5).
5. Pull the flexi-hose (4) back again so that the connector bush (3) reaches into the hole (1), the collar
underside facing the bottom plate. The cut-out in the bottom plate leaves room for the clamp when
it is turned correctly.
6. Pull the insulation sleeve (6) over the flexi-hose (4).
Perform the following steps for the insert:
7. Break off the pre-cut rectangular plate (7) in the automatic cassette cover (8).
8. Fasten the cover (8) on the automatic cassette (9) using two self-tapping screws (10), one on either
side of the cover.
9. Fasten the box (11) to the automatic cassette cover (8) using two screws (12) in the pre-drilled
holes.
10. When the casing (13) has been mounted, push the insert (14) into the casing. Make sure it clicks into
place in the bottom plate.
