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.
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.

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.
