Installation
SELECTING THE INSTALLATION
POSITION
• The 40DMC unit is designed ducted insta -
ation in suspended cei ings.
• The unit must not be accessib e to the pub-
ic.
• As a ru e, the unit cannot be insta ed at a
height of ess than 2.5 m.
• It is possib e to insta the unit at a height of
between 2.2 m and 2.5 m from the ground if
the system is configured for intake from the
rear. In this case, it is necessary to provide
an intake duct with minimum ength of 250
mm.
Avoid the following:
• Positions exposed to direct sun ight.
• Areas near heat sources.
• Damp p aces and positions in which the
unit cou d come into contact with water (e.g.
aundry rooms).
• Rooms in which she ving or furniture may
obstruct the f ow of air.
Do the following:
• Se ect a position capab e of supporting the
weight of the operating unit.
• Leave sufficient space around the unit for
maintenance and free circu ation of air (see
figure).
• Leave an aperture in the suspended cei -
ing or ensure that a part of the atter can be
removed for carrying out maintenance oper-
ations on the unit.
• Se ect a p ace which is free from dirt, for-
eign bodies or other materia that may
obstruct the coi .
• Suitab e dampers must be p aced between
the brackets of the unit and the hanging sys-
tem so as to prevent noise transmission.
• Insta the unit in such a way that conden-
sate can be drained easi y to a suitab e
waste out et.
Note: A dri ing temp ate has been provided
on the unit packaging to faci itate insta a-
tion.

INSTALLING THE UNIT
Important: the nit m st be correctly
levelled.
Insert the 4 M8 threaded tie rods into the
cei ing. Insert the other end of the tie rods
through the s ots in the hanging brackets
on the sides of the unit. Position the anti-
vibration dampers, add the washers and
tighten the nuts unti the unit is correct y
fixed and eve ed. If space permits, p ace a
ayer of rubber or neoprene between the
cei ing and the unit.
On comp etion of these operations it is
necessary to:
• insta a suspended cei ing to concea the
unit;
• inc ude a removab e pane for future
maintenance work;
• fit suitab y sized gri es in the suspended
cei ing to a ow air intake.
CONDENSATE DRAINAGE
Important: do not lift the nit by means
of the condensate drain pipe.
A units are equipped with a condensate
co ection tray with 21 mm externa Ø drain
pipe.
Therefore fit a pipe for the evacuation of
condensate.
Adhere to the fo owing recommendations:
• Use pipes in ga vanised stee , copper or
transparent p astic. Do not use norma gar-
den hoses.
• Use materia which ensures that the drain
pipe connections are tota y sea ed.
• If using rigid materia for the out et pipe, fit a
number of f exib e coup ings to absorb any
vibrations from the unit.
• The drainage ine must a ways be be ow
the connection itse f, with a suitab e gradi-
ent to faci itate outf ow.
• Pour a few itres of water into the conden-
sate co ection tray and check that it f ows
out correct y. If not, check the gradient of
the pipes and ook for possib e obstruc-
tions.
INTAKE CONFIGURATION
Important: nits config red for intake
from below m st not be installed at a
height of less than 2.5 m from the
gro nd.
The unit is factory-configured for air intake
from the rear.

It can be configured for intake from be ow
simp y by inverting pane s A and B.
During the operation, take the fo owing
precautions to avoid damaging parts of the
unit:
remove the fi ter.
Before removing the rear pane (A) pu the
drain pipe out of its seat by pressing gent y
on the sides.
When fitting the rear pane , take care not to
damage the insu ation of the pipes with the
edges of the pane s. On comp etion of the
operation, fit the fi ter.
AIR OUTLET CONFIGURATION
The Carrier 40DMC unit is predisposed for
either side or front air out et.

GB-12
Do not adopt configurations other than
those indicated above, as this may com-
promise the correct operation of the unit. In
particu ar, avoid operating the unit with just
one aperture.
Predisposition of the nit for circ lar
front o tlets
The unit is supp ied with a front enc osure
pane with 8” diameter circu ar cut-outs.
Before removing the cut-outs, cut the insu-
ation on both sides of the pane with a suit-
ab e knife. This faci itates opening and pre-
vents damage to the insu ation.
After removing the cut-outs, make certain
that the insu ation covers a the parts in
stee sheet.
After removing the cut-outs, rep ace the
front pane of the unit.A so using the screws

ENGLISH
The area of the pane which can be used
for fixing the 8” circu ar f anges (not sup-
p ied) is as shown in the figure. Avoid
dri ing or fastening screws in the shaded
area of the figure so as not to damage the
unit’s tray.
Installation with side o tlet
The unit is predisposed so that it can be
insta ed in corridors to make optimum use
of the two circu ar out ets on the sides. In
order to prepare the unit for this type of
insta ation, proceed as fo ows:
remove the two cut-outs in the sides of the
unit.
After remova , make certain that the insu a-
tion covers the stee sheet around the cut
area.
The area which can be used for fixing the
8” circu ar f anges (not supp ied) is as
shown in the figure.
Avoid dri ing or fastening screws in the
areas high ighted in the figure so as not to
damage the unit’s tray.
Rep ace the front pane of the unit with the
pane supp ied.

FRESH AIR INTAKE
There is a cut-out on the side of the unit,
which can be used as a fresh air intake. It
can be opened with a screwdriver.
DUCTING
Important: the d cting m st be
designed and calc lated by q alified
technicians.
Determine the dimensions of the ducts
according to the air f ow rate required and
the avai ab e static pressure of the unit
(refer to the fan diagrams on previous
pages).
You are advised to adhere to the fo owing
recommendations:
• regard ess of the type of duct used, it
must not be made of inf ammab e materia ,
which produces toxic gases in the event of
fire. The interna surfaces must be smooth
and not contaminate the air passing
through them. You are advised to use
ducts in ga vanised stee , suitab y insu at-
ed, to prevent the formation of condensate
and therma osses.
• The ducts shou d be joined with f exib e
coup ings which absorb vibrations, prevent
noise transmission inside the ducting and
a ow access to the unit.
• As far as possib e, avoid bends near the
unit’s air out et. If this is not possib e, the
radius of curvature must be as wide as
possib e; use interna def ectors if the duct
is of arge dimensions.

Warning!
Connect the indoor and outdoor units using copper pipes with f ared connections (not sup-
p ied). For the ines, use insu ated, unwe ded, degreased and de-oxidised copper pipe,
(Cu DHP type to ISO 1337), suitab e for operating pressures of at east 4200 kPa and for
a burst pressure of at east 20700 kPa. Copper pipe for hydro-sanitary app ications is com-
p ete y unsuitab e.
