INSTALLATION OPTIONS

The side openings allow a separate outdoor air change intake duct (B) and a delivery duct to convey treated
air towards an adjacent room (A) to be made.
Outdoor air change:
· Remove the outer condensation-proof insulation delimited by the die-cut and take out the micro-jointed sheet
metal panels using a punch. Take care to prevent the heat exchanger bank at the rear from being damaged.
Trim the inner condensation-proof insulation along the perimeter of the opening.
· Use locally purchased material able to withstand a continuous temperature of 80 °C. The ducts can be the
flexible type in polyester (with a spiral steel core) or in corrugated aluminium covered on the outside with
condensation-proof material (12 - 25 mm thick fiber-glass).
· After installation, the non-insulated surfaces of the pipes must be covered with condensation-proof material
(e.g. 6 mm thick neoprene foam).
Failure to comply with these instructions could lead to dripping through condensation . The Manufac-
turer is not liable for damage of this type .
· An appropriately sized fan must be installed to overcome the drop in pressure caused by the air change intake
port, duct, filter, etc.
· For winter operation with outdoor air changes, it is advisable to install an antifreeze thermostat with a 2 °C
setting and bulb on the water outlet pipe, that activates and deactivates the supplementary fan.
· The outdoor air flow rate must be less than 10% of the total air flow rate to prevent operating faults or noisy
operation.
· Install an intake grille with filter holder accessible for inspection outdoors to prevent dust and leaves from
being sucked in and irreparably clogging the thermal exchange bank of the interior unit. Filter installation also
does away with the need to install a channel air lock for idle periods.
Air delivery into an adjacent room:
If air is to be blown into an adjacent room, one or more of the fins corresponding to the duct must be shut off.
Apply an air intake port to the partition wall between the conditioned room in which the unit is installed and
the addcent room, as shown in the figure.
