Ceiling diffusers
It is recommended to suspend plenum boxes for
ceiling diffusers before you put the ceiling tiles into
place; if this is not possible, remove the adjacent
ceiling tiles. Nominal sizes 160 and 250 can be
installed at a later stage if the duct is already in
place.
Use only approved and adequately sized suspen-
sion systems (fixing material is not included in the
supply package). Dimensions and weights are
given in the technical leaflets.
Only work in pairs; preferably use a lift.
