Unit Structure And Positioning; Shortening Extension Duct - Maico PPB 30 K Montageanleitung

● The measurements will be incorrect if the in-
stallation location of the control and external
sensors is inappropriate. Avoid disturbing
influences and direct sunlight.
● RLS 45 O/K with LEDs. For RLS 45 K, the
brightness can be set and/or switched off
using the commissioning software. If people
are being disturbed by bright LEDs (in
bedrooms, for example), choose a suitable
installation location.
● Quiet changeover noises when the fans
change direction of rotation. Do not install
PPB 30 in bedrooms.

9.3 Shortening extension duct

The following preparations must have been
completed  PPB 30 assembly instructions
for shell mounting.
1. Install wall sleeve [1] so that it protrudes
5...10 mm beyond the finished plaster of
the external wall and has an incline of 1 to
2 % to the external wall. The sleeve must
be sealed from the wall with silicone.
2. The external cover is already mounted.
3. The control cables of ventilation units,
sensors and accessory components must
be routed in the empty ducts.
To shorten the extension duct, proceed as
follows:
4. Slide extension duct [5] into wall sleeve
with centring ring(s) [4] and if necessary
[6] up to stop of external cover. Ensure
that the centring ring is positioned as far
inside as possible. With PPB 30 VS exten-
sion, use two centring rings (position as
far inside and outside as possible).
5. Take off front cover of internal cover's
housing. 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 fitted internal housing and slide onto
extension duct so that the fluid separator
[3] is firmly connected.
7. Accurately measure distance between
internal cover and wall (dimension "x"
in mm).
8. Take all components out of wall sleeve.
