Commissioning
An IBIS C or a flow measuring damper installed in the duct
system upstream of the duct diffuser is recommended for com-
missioning and airflow measurements.
Maintenance
The air diffuser can be cleaned, if necessary, using lukewarm
water with dishwashing detergent added or by vacuum cleaning
using a brush nozzle.

Installation
The duct diffuser is suspended by hangers from the ceiling. The
air diffusers can be installed as in the following examples:
Phase A
• While the duct section (1) is lying on the floor, insert a
size M-8 bolt (2) approx. 100 mm from the end on the
longitudinal profiled bracket (3). Do the same in the
other end of the profiled bracket.
• Secure the bolts in the profiled bracket with long nuts (4).
Screw a threaded rod (5) of appropriate length into
each long nut.
• Secure the Z-profiled brackets (6) with bolts to the cei-
ling to serve as mounting brackets for the duct-shaped
air diffusers with discs.
• Hang the duct air diffuser with discs (1) in the Z-profiled brack-
ets (6) and join it together with the connecting supply air duct
(7) using the standard duct joint (8) included in the supply.
• Adjust the duct diffuser using the nuts (9) until the air
diffusers are horizontal and have the correct height above
the floor. Fit the white plastic covering supplied (15) onto
the threaded rod.
Phase B
• Remove the end cover (13) and move it to the outmost
section if more sections are to be installed. Press the
distribution joint supplied (10) in the mounted section of
the duct diffuser (1).
• Insert the guide pin (11) in the free end of the installed
section.
• Repeat phase A to install the next section (12). Now it
is sufficient to use one bolt in the other end when the
second duct diffuser section is to be secured across the
joint to the section that you’ve already installed. Secure
the distribution joint (10) with self-tapping screws in
the sections. Repeat Phase B for last section.
Phase C
• Install the inactive IBIS D duct sections (14) in the same
way as the duct air diffuser sections with discs. Note the
use of supplied joints (8) and distribution joints (10)inclu-
ded in the supply.
• In all deliveries, the end cover (13) supplied is already
fitted to the first section. The end cover is always moved
to the last section (except when only 1500 mm long
ducts are installed), see Phase B in Figure 3.
