INSTALLATION OF THE INDOOR UNIT
- Mark the position of each supporting rod, cooling pipes,
drainpipe of condensates, wires of power supply and cable of
remote control .
The supporting rods can be fixed, depending on the type of
ceiling.
Various models to fix
- Fix the angle brackets provided with the unit, on the threaded
rods , we recommend Ø 6, max.Ø 8,
and keep them away from the ceiling at a distance of 270mm or
107mm .
GENERAL POINTS
BEFORE INSTALLATION
- It is recommended to place the indoor unit as close as possible
to its final location before unpacking.
- Avoid to lay heavy tools or weights on the packed unit.
Check as soon as the packing is opened, that no accessories
required for the installation, are missing. The grilled panel is
provided separately for better protection.
DO NOT LIFT THE UNIT BY GRASPING THE
DRAINPIPE OF CONDENSATES OR THE
COOLING CONNECTIONS, BUT ONLY THE
FOUR CORNERS.
CHOICE OF LOCATION
- Do not install the un it in rooms where inflammable gas or acid
or alkaline substances are present. Aluminium and copper
evaporators and/or plastic components inside could be
damaged.
- Do no install the unit in workshops or kitchens; oil vapours
attracted by treated air could settle on the evaporators of the
unit and change its performance or damage plastic parts inside.
- The indoor unit is flush mounted into a false ceiling, size of the
tiles 600x600 and multiple.
- Installation of the unit is made easier when using a fork-lift truck
and the base of the packing by placing the base between the
unit and the forks of the truck .
- It is recommended during installation to choose the location of
the unit as much as possible in the middle of the room, so as to
obtain the best distribution of treated air.
- Check that you can remove the discharge grilles and that the
clearance is large enough to allow maintenace and repairs.

Nut
- In case the brackets are assembled at the lower part, remove
the insulating foam around the fixing nuts .
The possibility to adjust the bracket at different heights leaves
the brackets free to fix them at the upper or lower part of the
cassette.
- Fixing the brackets at the lower part offers an easier assembly.
Do not tighten the nuts, nor the counter-nuts, this should only be
done after having made all connections and placed the unit in its
final horizontal position.
- Lift the unit (without the frame) carefully by picking it up at the
four corners.
- Place the unit in the false ceiling.
- To make the assembly easier the electrical box can be
disassembled by removing 2 screws, and disconnect the
multipoints connector (15 pts connector for the main connection)
and small connector for the infra-red.
- Fix the cassette, connect the multipoints connectors, place the
cassette into is final position and reset the electrical box with 2
screws
- Fix the screws to fix the corner irons .
- In case the false ceiling is 300 mm distant from the ceiling (mini-
mum height admitted) it may be necessary to remove
temporarily a few T-shaped rods from the false ceiling.
- Position the unit with a level and keep 10mm between the sheet
metal body and the false ceiling .

T-shaped rod
- Position the unit on the supporting rods of the false ceiling by
first tightening the bolts on the side , then the nuts and counter-
nuts of the threaded rods . Finally place the rubber mount.
- Check once more that the unit is in a horizontal position after
connection of the condensate drain and the refrigeration
pipework.
DRAINING CONDENSATES
- To obtain correct condensate drainage , the slope downwards
should be 1 cm per meter without any bottleneck nor passage
upwards . Furthermore a trap of at least 50 mm high should be
mounted to avoid bad smells in the room.
- Install an auxiliary pump to drain condensates and a levelcontroller
if the condensates are to be drained at a higher level than the
unit. It is recommended to install an appliance equipped with a
safety floater to stop the compressor in case the auxiliary pump
is damaged.
- The drainpipe of condensates should be heat insulated with
insulating material 5 to 10 mm thick, such as polyurethane,
propylane or neoprene, avoiding condensation.
- If several units are placed in the room , the draining system can
be made as indicated above.
