5.2.5 Ceiling connection duct
For units that wish to connect with a suspended ceiling, a connection duct can be used
to create an air path.
The ceiling connection duct is made of the same material as the unit's panels. The
height of ceiling connection ducts are made to specification and they can bolt onto the
top of the close control unit through a service panel on either side.

5.2.6 Horizontal air discharge
For upflow units that do not have ceiling voids, a horizontal air discharge section can
be used to change the airflow direction.
The design can have a grille on the front panel only (1 way blow) or grilles on the front
and sides (3 way blow).
The assembly is bolted onto the top of the unit through the frame. This can be
accessed via the service panels on either side of the unit (for 3 way blow, remove the
grille for access).

5.2.7 Protection grille
This is the standard grille that is placed directly on top of the unit to protect individuals
from the rotating fan blades during operation. The grille design is different for upflow
and downflow units. The W-Version side section doesn’t have this grill as there is a
panel at the top of the unit.
