4.1 INSTALLATION LOCATION
Installing the cassette will be easier with the use of a fork
lift truck. Use the packing base by placing it between the
cassette and the truck forks.
It is recommended to install the cassette, as far as is possible,
in the centre of the room, in order to optimise treated air
distribution.
For the chosen location, check that the distribution grilles
can be removed and that there is sufficient space available
for access for maintenance and repairs.
When fitting the angle attachment fittings in the low position,
remove the insulating foam from around the mounting
nuts.
The possibility of fitting the angle attachment fittings
at different heights, leaves the installer the choice of
mounting them on the cassette in the high or low position.
Mounting them in the low position provides for more flexible
installation.
Do not tighten the nuts or lock nuts. This will be done only
after having set the cassette in its final horizontal position,
when are the connections have been completed.
4.2 CEILING MOUNTING
Mark the position of each support rod.
Refer to Chapter 2“Dimensions”
The cassettes must not be positioned above
electrical equipment in order to avoid exposure
to water leaks which may occur under extreme
conditions.

Fit the angle attachment fittings supplied with the cassette
onto the threaded rods (not supplied). Recommended Ø 6
mm maximum Ø 8 mm. Take care to distance them from
the suspended ceiling by 270 mm or 107 mm.
Take care !
Do not install the cassette in a room where gasses, acids or
inflammable products are stored, in order to avoid damage
to the aluminium and copper evaporators and the internal
plastic parts.
Do not install the cassette in a workshop or a kitchen. Oil
vapour attracted by the treated air could form deposits on
the cassette evaporators and modify their performance or
damage the cassette’s internal plastic parts.
Do not install the cassette in a laundry, or a room where
steam is produced.
The cassette is designed to be built into a suspended
ceiling with panels dimensions of 60 x 60 cm, or multiples
thereof.

4.4 CASSETTE INSTALLATION
Side openings are provided for installing separate ducts for
outside air intake and treated air distribution to an adjacent
room.
Use a punch to remove the condensation protection insulation
and the pre-punched panels from the openings.
TAKE CARE not to damage the heat exchanger coil
located behind the openings.
Plug the gaps between the ducts and the opening edge with
anti-condensation insulation.
Use material which can withstand a continuous operating
temperature of 60° C. The ducts can be of the flexible type
with a spring core or of corrugated aluminium, covered
inside with an insulating material (12 to 25 mm thick glass
fibre).
If it is indented to install ducting to an adjacent room, refer to § 4.4 for
removal of the pre-punched panel before installing the cassette.
4.3 CASSETTE FITTING
To make the assembly easier the electrical box can be
disassembled by removing 2 screws, and disconnect the
multipoints connectors (15 pts connector for the main
connection, 12 pts connector for the electric heating) and
small connector for the infra-red.
Fix the cassette, connect the multipoints connectors, place
the cassette into is final position and reset the electric box
with 2 screws
Fix the screws to fix the corner irons
In the event that the suspended ceiling is 300 mm from the
ceiling (minimum permitted height), it might be necessary
to temporarily remove some of the suspended ceiling T
supports.
Position the cassette on the suspended ceiling support
rods, and start by tightening the side mounting bolts, then
the threaded rods nuts and lock nuts, after having set the
cassette level, maintaining a gap of around 10 mm between
the metal chassis and the suspended ceiling.
Decompression grille
When the installation is finished, all the surfaces of the
non-insulated ducts must be covered with anti-condensation
insulation material (6 mm thick expanded polystyrene or
expanded neoprene). Fireproofing classification: M1)
IF THE ABOVE INSTRUCTIONS ARE NOT FOLLOWED,
CONDENSATE LEAKS MAY OCCUR.
Distributing air to an adjacent room requires one or two
of the corresponding ducts’ air distribution flaps to be
closed.
A decompression grille must be fitted in the partition between
the air conditioned room (where the cassette is installed)
and the adjacent room.

For heights above 0.60 m, an auxiliary condensate pump
with a level regulator should be installed.
Furthermore, a siphon with a height of at least 50 mm must
be provided to avoid any unpleasant odours in the room.
5.2 HYDRAULIC CONNECTIONS
For the system to operate in complete safety,
regulating valves must be fitted, if they are not
already fitted at the factory.
The regulation valves are installed inside the cassettes. A
lock spanner must be used for tightening the pipe work.
The first time the cassettes are filled with water
to check the tightness of the circuits, they can
be filled on a temporary basis, without power
being connected to the unit. If, on the other hand,
continuous water circulation is planned, the units
must be connected to the power supply to ensure
condensate drainage by the draining pump and
to avoid the condensate tray overflowing.
WARNING !
WARNING !
For connecting the coils the use of stop cock valves with
flexible pipes is recommended.
It is imperative to envisage a support of these pipings
independently of the cassette.
The connection must not be over tightened.
The hot water coil air purge must be done through the water
outlet connection (8

9.2 GENERAL INSTALLATION
Carry out a visual inspection of the installation in
operation.
Check the overall cleanliness of the installation and check
that the condensate evacuation is not blocked, particularly
that of the evaporator coil.
Check the condition of the condensate tray.
For the installation to operate correctly, it is imperative that
the air filter, located on the air intake of the treated air coil,
is cleaned regularly.
Check the connections seals and, if required, insulate the
evacuation pipes to protect against frost or condensation.
Check that the air distribution flaps are open.
Cleaning intervals vary depending on the amount of
impurities in the air to be conditioned. It is recommended
that the filter is replaced at regular intervals.
A dirty filter creates a decrease in air flow across the heat
exchanger, which decreases the installation’s output and
hinders fan motor cooling.
Check the state of cleanliness of the indoors coil.
9.3 ELECTRICAL ELEMENTS
Check that the mains supply cable is free from any damage
which might effect insulation.
Check the tightness of the electrical connections.
