8.3 Shortening extension duct

The following preparations must have been com-
pleted → Shell installation instructions.
1. The wall sleeve has been installed in such a
manner that it protrudes 5...10 mm beyond the
finished plaster of the exterior wall and has an
incline of 1 to 2 % to the exterior wall. The
sleeve must be sealed from the wall with silic-
one.
2. The external cover is already mounted.
3. The control cables of ventilation units, sensors
and accessory components must be routed in
the empty tubes.
To shorten the extension duct, proceed as fol-
lows:
4 Centring ring
5 Extension duct
6 Centring ring
4. Slide extension duct into wall sleeve, with
centring ring(s), up to stop on the external
cover. Ensure that the centring ring is posi-
tioned as far inside as possible. With
PPB 30 VS extension, use two centring rings
(position as far inside and outside as pos-
sible).
5. Take off front cover of internal cover's hous-
ing. To do this, press the two locking levers on
the underside up a little and take off the cover.
6. Insert slide-in module into wall sleeve with fit-
ted internal housing and slide onto extension
duct so that the fluid separator is firmly con-
nected.
7. Accurately measure distance between internal
cover and wall (dimension "x" in mm).
8. Take all components out of wall sleeve.
CAUTION Risk of injury when handling
housing parts with sharp edges, e.g. burrs.
Wear protective gloves.
9. Saw extension duct to x + 5 mm. Deburr saw
cut.

8.4 Gluing on sealing bands

3 Fluid separator, outside
3.1 Sealing strip
5 Extension duct
7 Sealing strip
1. Glue sealing strips onto the outside of the duct
end of the fluid separator and/or onto the out-
side of the extension duct so that it terminates
flush at the face end.
NOTICE Damage to brickwork caused by con-
densate if the sealing strips are fitted incor-
rectly.
Glue in sealing strips correctly.
