Installation sequence
1
Install drop rod anchor points, and M10 drop rods to support
the damper, using the AFS (Adjustable frame system). M10
drop rod lengths should be a maximum of 1,000mm in length.
Where longer lengths are required, the bottom 1,000mm of M10
drop rod should be joined to an M16 drop rod above for the
remainder of the length, using M16/M10 transition pieces.
2
Slide the AFS rails on each side of the damper into the brackets
and insert the "Z" piece into the bracket slot pushing it up against
the underside of the rail. Insert the 8mm bolt from above into the
slot through the "Z" piece fitting the nut until tight to secure the rail.
3
The drop rods are to slide through the slots in the rail and a nut
screwed on to take the support of the damper rail. The damper
must then be levelled, and when in the correct position the nut
above the rail should be tightened against the rail.
4
The damper is mounted to the duct using self tapping fixings,
at 150mm centres. When the damper is slid into the duct, an
overlap of up to 40mm is permitted, allowing for 10mm for duct
expansion.
5
The connecting galvanised mild steel ductwork must be
independently supported within one metre of the connections
and have been installed in accordance with DW144.
6
An access door should be fitted on the access side of the
damper for inspection and maintenance of the damper.
7
The damper operation should be checked to ensure that it fully
opens and closes.
8
When the damper installation has been completed checks
should be made to ensure the AFS rails are secure and there is
no movement, operation of the damper should be checked.
