3.1 - Installing the unit in the false ceiling
The positioning of the unit must not create an obstacle that
may lead to an unequal distribution and/or return ow of
the air.The ceiling must be sufciently even to allow a simple
installation without danger from the unit. The supporting
structure must be able to carry the unit weight and prevent
deformation, breaks or vibrations during operation.
INSTALLATION PRECAUTIONS: During the
installation process, remove all debris and construction
material from the ducts to prevent any damage to the unit.

NOTE:The fan-coil units are delivered upside down when
stacked on a pallet.
• Position the unit close to where it is to be installed in
the ceiling void. For installation in a false ceiling use
a hydraulic lift and a folding ladder to make the task
easier (Fig. 7).
• Check that the clearances around the unit are
sufcient to allow easy maintenance. Please refer to
the diagram that shows the service clearances.
• Mark the position of the threaded hangers on the
ceiling (if several units need to be installed,it may be
advisable to produce a drilling template).The method
of fixing the threaded hangers (not supplied by
Carrier) depends on the ceiling type (maximum
diameter of the threaded hangers is 10 mm).Once the
threaded hangers are xed to the ceiling, tighten the
rst nuts.
WARNING:When moving the units, do not use water pipes,
condensate drain pan, valves or exible pipes to lift them.
‘Without lter’ unit must be connected to an air ductwork.
It is not allowed to operate the unit without any lter and
with a free inlet at the same time.
Lift the unit and align it on the threaded hangers, insert the
second nuts and tighten them slightly.
NOTE: At this point do not tighten the nuts fully and do
not clamp the unit up to the ceiling (leave a space between
the ceiling and the unit). The nuts will be adjusted nally,
when the unit has been connected to the pipework and ducts
and levelled.
Level the unit (Figs. 8 and 9).
Adjust the hanger nuts so that the unit is inclined 0.5%
towards the condensate drain pan. In the other direction
(air ow direction) the unit must be perfectly level (Figs. 8
and 9).
Condensate drain pipe (Fig.10):Use a exible pipe with an inside
diameter of 16 mm and provide a constant fall of 20 mm/m over
the whole horizontal pipe run.Install a 50 mm (minimum) siphon
to prevent gases and odours from owing back into the ceiling
void.
WARNING:After drain pipe connection, control clamping
of the drain pipe and be sure there is no water leakage.

20
ENGLISH
If several units are connected to a common collector, a
device must be installed (Fig.11).Before operating the unit,
ensure that the water ows into the internal condensate
drain pan by pouring some water into it. If problems are
detected, check the drain pipe slope and look for possible
obstructions. In all cases the connection duct(s) at the unit
outlet must be insulated to prevent any condensate
formation on the walls.
NOTE: The pressure losses of these ducts must be
compatible with the unit performance. The duct must be
as smooth as possible.Avoid sharp bends. Check that there
are no leaks or kinks, and that there is no dirt or
installation debris inside the ducts. Debris within the ducts
might damage the fan wheel and the damper in the air
diffusers.
When installation is complete - i.e.when the unit is attached
to the ceiling, air ducts are complete, water mani-folds are
in position with stop valves ready on the connection stubs,
and electrical installation is prepared - then connect the
water pipe (1/2” gas screw connector for size 2 to 5 ; 3/4”
gas screw connector for size 6 and 7).
WARNING: Be sure that the coil protective caps are
removed before connecting the water pipes (see Fig. 19).
NOTE : Each fan-coil units shall be connected with water
flexible pipes in order to avoid any damage due to
vibrations.
Ensure that a gasket (not supplied by Carrier) is installed
between the screw connector and the stop valve.
When all units are installed, open the stop valves on the
manifolds, bleed and then pressurize the circuits. To bleed
the coils, slightly loosen the bleed screws. The installation
can then be started.
NOTE: Do not switch on the power until all connections
are made and earthed.
