SDFS Series Fixed Blade Swirl DiffuserProduct Description
SDFS Fixed Blade Swirl Diffusers
Tools Required1 x Large cross head screwdriver 1 x Pop riveter1 x ø3.5mm drill bit
1 x Power drill
Note: Power tools are not recommended for this installation due to the risk of damage caused by the over-tightening of the hanging bracket screws.
Plenum Installation:
1- Install the plenum box, suspending it from its mounting holes with Drop Rods (supplied by others). Use locknuts and washers above and below the mounting holes to set the plenum box height. If
vertically, in line with the plenum mounting holes.
2-
plenum in both directions within the opening where

the ceiling grid, raise the plenum box approximately
200mm (or as required) above the grid to allow

4- Locate one end of the diffuser into the ceiling
opening, and in a sliding motion move it to the far end
of the opening (Figures 3).

5- Once the diffuser is positioned, lower it into the
tee bars of the ceiling grid (Figures 4).
6- Lower the plenum box over the rear stack of the
diffuser (Figures 5). Take care to ensure that the
stack is positively located within the plenum collar
(Figures 5a). Do not tighten the drop rod lock nuts
at this time, as some adjustment may be required.
7- Once you are happy with the plenum position, take
the plastic cap from the screw and secure the diffuser
to the plenum as shown in (Figures 6). Take care not
to over tighten the screw as this could distort to the
diffuser face.

Duct Mount Installation
An alternative method of installing this range of diffusers is the use of a steel duct mount collar. This allows rigid ductwork to be connected directly to the rear of the diffuser. These duct mounts are supplied to order, and the installation instructions are as follows:
1- Take the diffuser and place it face down on the
table, taking care to lay it on something to protect the
2- Orientate the duct collar so that its mounting bar
‘U’ channel is open to the top, then place the collar
over the rear stack of the diffuser. Take care to ensure
that the stack is positively located within the collar
(Figures 9).

supplied. Stand the diffuser on edge whilst still holding
and secure the diffuser to the duct collar as shown in
(Figures 10). Take care not to over tighten the screw
as this could distort to the diffuser face.
Plenum Installation:
8- This operation may cause the diffuser to be lifted
off the ceiling grid creating a gapping effect (Figures
7). If this occurs, adjust the height of the plenum and
diffuser by raising or lowering the assembly using the
lock nuts on the plenum drop rods until the desired
effect is acquired.
9- Finally, clip the plastic cap back onto the head of

tee bars of the ceiling grid (Figures 12).
7- Rigid Ductwork
a- Lower the ductwork on the drop rods to allow
it to slide over the exterior of the duct collar.
continue this until it reaches the swage line as
shown in (Figures 13). Anchor it in position using
the lock nuts on the supporting drop rods.

7- Rigid Ductwork
b- Secure the ductwork by drilling through it and
the duct collar above the swage line, then riveting
or screwing them in place (Figures 14). Do not
the swage line as damage to the diffuser may
occur.
