Air intake grille
Fresh air renewal and conditioned air supply to an adjacent room
• Side knockouts allow connection of fresh air inlet ducts and ducts
to deliver conditioned air to an adjacent room.
• Remove the external prepunched anti-condensate insulation and
take away the knockout panels using a punch.
Air distribution to adjacent room
With a pencil, trace a line on the polystyrene around the inside
edges of the panel that was previously removed.
Cut away the polystyrene with a knife, taking care not to damage
the heat exchange coil.
Fresh air intake
Remove the polystyrene partition.
Introduce the baffle supplied after the frame has been hooked as
per above figure (ref. ቩ).
Following that tighten the assembly frame/grille using the 4 screws.
• Use locally purchased material, suitable for operating
temperatures of 60 °C (continuous).
Conduits can be of flexible polyester (with spiral core) or
corrugated aluminium, externally covered with anti-condensate
material (fibre glass of 12 +/- 25 mm thickness).
• To complete the installation, all non-insulated ducts must be
covered with anti-condensate insulation (ex. expanded neoprene,
6 mm thickness).
If these instructions are not observed, condensate may drip;
the manufacturer will not be held responsible for any damage
caused.
• The two prepunched side knockouts must not be used at the
same time to deliver conditioned air to an adjacent room.
• The return and supply duct lengths can be calculated in
accordance with the "air distribution to an adjacent room" and
"fresh air renewal" diagrams (also taking into account the
pressure drop through air diffusers, grilles and fresh air filters),
as well as the increase in noise caused by these ducts.
