FRESHBOX 60
Unit mounting sequence:
1. Fix the master plate from the delivery set on the wall with a sealing tape on
required level, fig. 5.
2. Use the master plate to mark two Ø 140 mm holes for the air ducts and two
Ø 8 mm holes for the dowels.
3. Remove the master plate and drill through holes sloped down by 2-3%
for the air ducts and the holes for the dowels, 60 mm deep. Then insert the
dowels from the delivery set. Fig. 6
4. Remove the perforated holes for the air ducts from the master plate. Re-
install it with a sealing tape. If you use either MS1 FRESHBOX 60 or MS2
FRESHBOX 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. 7. 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 to prevent condensate dropping on
the wall.
7. Mounting sequence of the unit:
a) take off the front cover and remove the heat exchanger, fig. 8;
b) connect the unit spigots to the air ducts, fig. 9;
c) fix the unit to the wall with 5.0x50 screws (screws and matching dowels are
included into the delivery set);
d) Install the heat exchanger and the front panel.
e) Mount the sensor speed switch, refer Connection to power mains and
control, page 8.
I
nstall the ventilation hood AH FRESHBOX 60 on the outer side of the building
to prevent ingress of foreign objects into the air ducts, fig. 10. The hood is not
included into the delivery set of FRESHBOX 60 unit and is available on separate
order (with the mounting kit MS2 FRESHBOX 60 or as AH FRESHBOX 60). The
ventilation hood AH FRESHBOX 60 may be replaced with any ventilation grille
or a ventilation hood of respective size.
