OPERATING LIMITS

All versions. The AX - AW - AF - AD - AT units are designed for
operation within the following operating ranges (the limits are
considered for new units that have been correctly installed and
maintained):
Environmental conditions
from 20,0°C,45% RH at 32°C,55% RH
Outside conditions
from +10.0°C to +46.0°C in BASIC version without condensing
control
from -20.0°C to +46.0°C in MODULATING version with con-
densing control
from -45.0°C to +46.0°C in the LT version (low temperature).
OPTIONAL BASE MOULDING (OVER 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.
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.
