2.5 INSTALLATION SITE
Preliminary warnings
The installation site must be decided by the
system designer or by another competent person, and
must be compliant with the technical requirements, as
well as the current legislation and regulations.
Before starting the installation, decide the position of the
unit taking into consideration the minimum technical
spaces.
It is recommended to avoid:
• Positioning the unit in air shafts and/or basement win-
dow wells.
• Any obstacles or barriers that will cause the expelled air
to recirculate.
• Locations in which aggressive atmospheres are present.
• Confined locations in which the device's sound levels
might be compounded by reverberations or resonances.
• Positioning in corners where dust, leaves, or any other
materials typically accumulate, which could compromise
the device efficiency by obstructing the airflow.
• Situations in which the air expelled from the device
might enter the habitation through doors or windows,
thus creating an inconvenience for the people inside.
• Situations in which the air expelled from the device will
encounter resistance from opposing winds.
• Direct exposure to sunlight and proximity to heat sources.
If the device is to be positioned in a windy location, the
fan must be protected by a wind-proof screen, and the
unit's proper operation must be verified.
The devices must:
• Be lifted from the ground to allow condensate outflow.
• Be positioned on a level surface that is capable of suppor-
ting their weight.
• Be positioned on a sufficiently rigid surface that will not
transmit any vibrations to the underlying or adjacent ro-
oms.
• It is recommended to place a rubber slab or properly
sized anti-vibration supports between the device and its
support surface.
The unit must be installed outdoor only.
In case of more devices placed side by side on the coil
side, it is necessary to add up the distances.
Lift the unit from the ground and adopt adequate anti-
freeze systems for installations in zones that are extremely
cold or subject to heavy snowfall, where the possibility of
freezing is present.
2.5.1 Recommended distances
The distances for the device installation and maintenance
are shown in the figure. The indicated spaces are necessary
in order to prevent the airflow from being blocked, as well as
to allow normal cleaning and maintenance operations to be
carried out.
