INSTALLATION OF COMBINED MODULE
PRANA-340S
The ventilation system of the combined version is mounted
similarly to the wall version 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 back of
the device) must protrude beyond the wall from the outside
at least 1-2 cm. 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 indicate the
thickness of the wall where the ventilation system is to be
installed.
The thickness of the wall must correspond to the distance
between the air intake grilles located on the body of the
air handling unit. The minimum distance between these
grilles and duct spigots is 350 mm, in which case the wall
thickness must be Lmin ≤ 330 mm (for PRANA-340S TYPE3).
The minimum distance between these grilles and duct
spigots is 440 mm, in which case the wall thickness should
be Lmin ≤ 420 mm (for the RANA-340S TYP6 system) If the
wall thickness is greater, the unit must be custom made with
the required distance between the grilles.
For service, it will be necessary to completely remove the
ventilation system from the wall.
The wall-mounted air handling units must be equipped
with heater elements to prevent the heat exchanger from
icing up.
If it is necessary to install a heater, a section of tidal air
duct must be additionally installed.
