9. INSTALLATION
The unit is not designed to withstand weights or stresses from adjacent equipment, pipe work or
constructions. Any foreign weight or stress on the unit structure could lead to a malfunction or a
collapse with dangerous consequences for personnel and property. In such an event, the warranty
shall be null and void.
9.1. INSTALLATION LOCATION
The cassette is intended to be installed ideally in the place of a suspended ceiling tile, panels dimensions of
60 x 60 cm or multiples thereof, in a ceiling with a minimum height of 2.5 metres and of 4 metres maximum.
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.
It is recommended to insure a sufficient ventilation
around the cassette.
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.
The cassettes must not be positioned above electrical equipment in order to avoid
exposure to water leaks which may occur under extreme conditions.

9.2. CLEARANCE
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.
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.
ENSURE THAT THERE IS SUFFICIENT FREE SPACE BETWEEN THE SUSPENDED CEILING
AND THE SOLID CEILING FOR THE UNIT TO BE LOCATED. 300mm MINIMUM
9.3. CEILING MOUNTING
Mark the position of each support rod (Refer to the § DIMENSIONS, page
II of appendix).
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(KOG
IRYS 276mm our 113mm).
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.

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.

9.5. 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).
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.

All ductwork connections to the unit must be made via flexible connections to prevent transmission
of vibration.
10. HYDRAULIC CONNECTIONS
The units may contain a small amount of oil incompatible with plastic polyethylene piping (PER/HTA/
PVC). The coil should be rinsed out before use to avoid any problem.It is the installer’s responsibility
to contact their pipe supplier and take into account the general instructions for the use of plastic
pipes (PER/HTA/PVC).
8

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.
It should be noted that over tightening the connections can cause excessive material
constraints during high temperature operation.
A counter wrench must be used for tightening the pipe work.
The hot water coil air vent must be done through the water outlet
connection (81).

For the system to operate in complete safety, regulating valves must be fitted, if they are not already
fitted at the factory.
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.
The use of regulation valves (factory-fitted, supplied as an accessory or by the client) is mandatory to ensure that
the appliance operates correctly.
The installation and operating conditions require the MANDATORY fitting of a valve ON the unit
OR/AND upstream in the hydraulic circuit. This is to prevent chilled water from circulating in the
appliance when the fan is not operational (condensation issue) or to prevent the simultaneous
circulation of chilled water and hot water in a 4-pipes exchanger.
10.1. CONDENSATE EVACUATION
To ensure effective condensate evacuation, the downward slope
must be 1 cm per metre without any restricted or ascending section.
The condensate extraction height is limited to a maximum of 0.60
metre.
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.
The condensate evacuation pipe must be heat insulated to a thickness of 5 to 10 mm with insulating material such
as polyurethane, propylene or neoprene (Fireproofing classification: M1) to prevent condensation.
If several cassettes are installed in the room, the evacuation system can be designed as illustrated below.
THE CASSETTE MUST ALWAYS REMAIN CONNECTED TO ELECTRICAL SUPPLY TO ALLOW
THE DRAINAGE OF WATER CONDENSATS.

Carefully unpack the module and fit the clips in the frame corners.
For infra red models, connect the flat cable from the receiver.
Present the frame to the unit, and apply pressure so that the clips engage. Then screw
it in place.
Avoid distorsions of the frame caused by excessive traction; the frame should be correctly
centered in relation to the false ceiling and it should especially ensure an airtight
separation between air succion and air discharge.
The seals are illustrated in the diagram below. They avoid:
