Installation
Cut an opening in the duct according to dimensions I
x J in the dimensions table. Place the air diffuser over
the opening and secure it with screws to the duct. See
Figure 1.
Commissioning
A flow measuring damper installed in the duct upstream
of the first duct diffuser is recommended for commission-
ing and airflow measurements.
Maintenance
The air diffuser can be cleaned, if necessary, using luke-
warm water with dishwashing detergent added or by
vacuum cleaning using a brush nozzle.
