•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. ).

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.
