OPTIONAL BASE MOULDING (A*O UNITS)
The "OVER" units are designed for the connections to pass
through the base of the unit; nonetheless, if there is no raised
floor (units with intake from the rear or front), to simplify the
connection of the pipes and cables, a base moulding must
be used.
The base moulding, available as an accessory, is epoxy-polyester
powder painted, in the same colour as the external panels on the
air-conditioner, measures 200 mm in height and is fitted with an
inspection panel at the front fastened by two latches tightened
1/4 of a turn.
The inside walls are lined with soundproofing material.
On the right- and left-hand sides of the base moulding are six
pre-cut sections for passing the cables and pipes;
The moulding must be fastened to the air-conditioner using the
M6 threaded inserts already arranged on the base.
For the OVER units with intake from the bottom, base mouldings
are available with a height of 500 mm.
In this case too, the air-conditioner must be screwed to the base
moulding during the positioning phase.

AIR DISTRIBUTION, UNDER UNITS (A*U UNITS)
In the units with air outlet from the bottom, the following details
must be ensured to allow for sufficient air flow-rate:
a) connection opening between the unit and the raised
floor; make a hole in the raised floor and position the air-con-
ditioner over the centre of the hole: the air outlet opening
must not be blocked, even partially, by parts of panels, beams,
pipes or other objects; insert an elastic gasket around the peri-
meter of the base to prevent the transmission of noise and
vibrations;
b) ) free air flow along the cavity of the raised floor;
the duct represented by the underfloor space must be suffi-
ciently high (at least 200-250 mm of free space, net of the
panels and the beams of the raised floor) and free of obstruc-
tions, especially near the air-conditioner;
c) grills and air distribution openings in the room;
the air exits the underfloor space through openings or grills,
the position and surface area of which must be proportional to
the layout of the thermal load of the environment.

For units with air outlet from the bottom, the recommended air
outlet speed from the raised floor is between 1 and 2.5 m/s; con-
sequently, the cross-section of the grills should be sized based on
this value
The total outflow area (sum of the areas of the openings and net
space of the grills) required for each model must be calculated by
dividing the total air flow-rate (in m3/s) by the required outlet
speed (in m/s).
WARNING: the air outlet must be completely free, as
an insufficient air outflow air will reduce the flow-rate,
the performance of the air-conditioner and may affect
reliability.
