CHILLED WATER CASSETTE

4.1

INSTALLATION LOCATION

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.
The cassette is designed to be built into a suspended
ceiling with panels dimensions of 60 x 60 cm, or multiples
thereof.

Refer to Chapter 2"Dimensions"
1220
1220
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 or 113mm).
i
nStallation
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.
Take care !
The cassettes must not be positioned above
electrical equipment in order to avoid exposure
to water leaks which may occur under extreme
conditions.
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.
