CAUTION:

If the air-conditioning unit(s) is (are) placed on brackets in the room, it is mandatory to

electrically isolate these brackets from the raised floor slabs, crossbeams, and actuators.

Computer Room Ceiling

It is extremely important to have sufficient ceiling height so that the premises may be air-

conditioned without creating draughts. Optionally, a suspended ceiling may be installed.

Ceiling or suspended ceiling height must be at least 2.50 meters. Insufficient ceiling height

may adversely affect the air-conditioning system and make personnel uncomfortable.

The primary ceiling and wall drops located at suspended ceiling level must be coated with

dustproof paint.

Suspended Ceiling

The suspended ceiling must be made of a non-pulverulent material (metal slabs or plates). To

avoid slab disintegration and the generation of dust, it is strongly recommended not to use

"mineral" type components.

Suspended Ceiling Features:

• reduces the sound level in the room,

• improves the appearance of the room,

• allows light fittings to be flush-mounted,

• conceals pipes, ducts or channels,

• glass or rock wool can only be used if contained in a dust-proof bag or cushion,

• suspended ceiling height: > 2.50 m,

• plenum space: > 20 cm.
