Correct use
Air terminal devices are used for the ventilation of
internal spaces in industrial and comfort areas.
The air terminal devices are connected to a
supply air or extract air system (by others), which
is typically connected to and air handling terminal
unit (AHU, FCU etc.).
Air terminal devices supply cold or warm air to
rooms (within the stated supply air to room air
temperature differences).
Installation, operation and maintenance may
have to meet increased hygiene requirements for
certain areas of application.

Adjustment screw

Installing the diffuser (Finite)
Ensure the grille border is flat and level
before fixing it in place. Secure using
counter sunk head 3.5 drywall screws (by
others) every 300mm.
Screw through the holes in the border,
through the plasterboard and into the timber
batten behind.
Ensure the screw heads are driven firmly
into the border and sit below the top edge of
the grille border so they will not visible when
the border is plastered. The border should
be firm with no movement. Jointing tape
should be applied over the plaster frame to
provide a good adhesion surface for the
plaster skim.
Suitable site masking of the diffuser is
required to prevent damage. The plaster can
then be applied using the top edge of the
diffuser border to level the plaster. Excess
plaster should be cleaned off the inside of
the diffuser & border before it dries to avoid
staining or damage to the paint finish.

Installing the diffuser (Linear)
Before installing the grille border into
the builder's work opening, arrange the
grille sections next to each other on a
clean, level surface with the alignment
pins to hand to ensure a good fit prior
to installation.
Insert the alignment pins halfway into the
alignment ports located in the border
extrusion on one grille section.
Then proceed as instructions for finite
diffusers.

TSD, apart from the alternating discharge variant, is supplied with the blades in the closed position
which need to be set on site by others. Setting the places is a two-hand operation, with hands at both
ends of the blade, to avoid deforming the blade. A non-metallic tool may be required to create a gap
between the extrusion and the blade. The blade should be opened until it hits the stop and can be
opened no further. It is common for TSD to be selected with slots discharging to both sides of the
diffuser, please refer to TROX schedule for slot configuration. Alternating discharge diffusers will have
the blades set in the factory.
