Unit installation
Insert 4 M8 threaded rods into the celling. Introduce the other end
of the rods through the slots of unit suspension brackets.
Position the shock absorbers, add washers and screw the nuts
down until the unit is correctly suported.
If there is sufficient space, a rubber or neoprene sheet can be
placed between the ceiling and the unit.
IMPORTANT:
The unit must be perfectly levelled.
Once these operations have been completed, an above-ceiling
installation will be necessary to conceal the unit; do not forget to
install a removable panel to allow for maintenance operations.
Grills of an adequate size should be incorporated in the unit for
return air suction.

Condensate drainage
All units are provided with an internal condensate drain pan which
incorporates a drainage tube 20 mm external Ø (009, 012, 018)
and 25 mm (024, 028, 036, 048, 060).
A tube for evacuating condensates must therefore be provided.
The recommendations below must be followed in all cases:
• Use galvanizad steel, copper or plastic piping.
Do not used ordinary garden hose.
• Use a material that guarantees perfect watertightness on the
drainage pipe.
• If rigid material has been used for the drainage, it is necessary to
provide some kind of elastic coupling in the drainage line to
absorb possible vibrations.
• The drainage line should always be below the connextion itself,
and should also slope to facilitate drainage.
WARNING:
No drillholes should be made in the base of the unit, since the
drain pans may be perforated.
Ductwork
The ductwork dimensions should be determined in accordance
with the air flow circulating through it and with the available static
pressure of the unit.
These information are available in the final pages of the manual.
Various suggestions are made herebelow, regarding the layout
and design of the said doctwork:
• Whatever type of duct is used, it should not be made of materials
which are flammable, or which give off toxic gases in the event
of a fire.
The internal surfaces should be smooth, and not conteminate the
air which passes through.
• At the points where the duct joins with the unit, it is advisable to
use a flexible connection which absorbs vibration and prevents
the transmission of noise inside the ductwork.
• Bends should be avoided as much as possible near the unit
outlet.
If unavoidable, they should be as slight as possible, and internal
deflectors should be used when the duct is of large dimensiones.
IMPORTANT:
Duct calculation and design must be effected by a qualified
technician.
