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.
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 450 mm.
In this case too, the air-conditioner must be screwed to the base
moulding during the positioning phase.
