Preliminary instructions
The place of installation must be determined by the system’s designer
or by an expert in the field and must take into account the technical
requirements and the current standards and legislation.
We suggest to avoid:
The placement in service ducts and/or hopper windows
Obstacles or barriers that cause a recirculation of the expelled air
Places with aggressive atmospheres
Small places where the unit’s noise level can be enhanced by
reverberation and resonance.
Placement in corners, where dust, leaves and other debris may easily
deposit ma reduce the efficiency of the unit, through obstruction of the
air flows.
The airflow from the unit can penetrate in the inhabited rooms through
doors or windows, creating discomfort.
That the airflow from the unit is opposed by a contrary wind.
The units must:
Be placed on a level surface able to support their weight.
Be placed on a sufficiently rigid floor slab that does not transfer
vibrations to the rooms below or next door.
It is suggested to place a rubber plate between the slab and the unit, or
to use anti-vibrating mounts appropriate for the unit’s weight.
The unit must only be installed outdoors.
If there are several units placed side by side on the bank side, the
required distances must be summed.
Provide for lifting of the unit from the floor:
20mm without conveying of condensation discharge
90 - 100 mm to allow the conveying of the condensation discharge
If the unit is installed in areas subject to heavy snowfall, it shall be
necessary to avoid the unit being directly exposed to it.
