PAPER MASTER PLATE FOR HOLE MARKING [MM] (INCHES)
The unit is mounted with the master plate from the
delivery set, fig. 1. Please prepare also two air ducts of
required length or one of the mounting sets MICRA 60.
The mounting set MICRA 60 is specially designed for
mounting of the unit at general construction stage. It
includes two plastic air ducts, each 19 13/16'' long and two
master plates for marking the holes on inner and outer wall
sides.

Unit mounting sequence:
1. Fix the master plate from the delivery set on the wall with a
sealing tape on required level, fig. 2.
2. Use the master plate to mark two Ø 130 (5 1/8'') mm holes for the air ducts and two Ø 8 (5/16'') mm holes for the dowels.
3. Remove the master plate and drill through holes for the air
ducts and the 60 mm (2 3/8'') deep holes for the dowels. Drill the
holes for the air ducts sloped down by 2-3.Then insert the dowels
(included intro delivery set) intro respective holes.
4. Remove the perforated holes for the air ducts from the master
plate. Re-install it with a sealing tape. If you use either MICRA 60
set, fix the master plate from the mounting set on outer wall side
to align the air ducts with respect to each other. Fix this master
plate somewhat lower to ensure the minimum required slope by
3° to outside.
5. Inset the air ducts into the master plate holes and seal those
with a mounting foam through the provided openings in the
master plate, fig. 4. Install the air ducts sloped down by 2-3°
outside to ensure the condensate drainage.
6. After the mounting foam hardening (see the solidification time
in the product specification) remove the master plates. At the
inner wall cut the protruding parts of the air ducts to be flush with
the wall. On outer wall side, the air ducts must protrude by 10 mm
(3/8'') to prevent condensate dropping on the wall.

by inserting those to the Ø 8 mm (5/16'') holes.
-Install the heat exchanger and close the front panel.
-Install the NB MICRA 60 outer ventilation hood outer of the
building to prevent ingress of large foreign objects into the air
ducts, fig. 5.
Attention! The round plastic air ducts and the outer ventilation hood are not included intro thr delivery set and are available on separate order. You may use other ventilation
grilles and hoods of the matching size.
