INSTALLATION OF THE WALL MODULE
PRANA-340S
The ventilation system of the wall version is mounted in
a hole of appropriate diameter (from 350 mm) with a 2-3°
slope towards the street.
The casing (excluding the air intake grille in the rear of the
unit) must protrude at least 1-2 cm outside the wall. Failure
to do so may result in condensed moisture entering the room
and causing failure of the ventilation system.
Before ordering this model it is necessary to note the
thickness of the wall where the air handling unit is to be
installed The thickness of the wall must correspond to the
distance between the air intake grilles, located on the case
of the unit.
The minimum distance between the grids is 350 mm, in
this case the wall thickness must be Lmin ≤ 330 mm. If the
wall thickness is greater, the unit must be manufactured to
order with the required grid spacing.
For service purposes, the ventilation system must be
completely removed from the wall.
Wall-mounted ventilation systems must be equipped with
a mini heater option to prevent the heat exchanger from
icing up.
If a duct heater must be installed, an additional section of
tidal ducting must be installed.
