Installation – Commissioning – Maintenance 20150318
Installation
The SIRI damper should be installed at a suitable distance
from obstruction sources. The SIRI damper must not be
strained by the weight from connecting ducts. This is
especially the case if it is connected to a vertical run of
ducts. In undisturbed measurement an accuracy of ±5% is
achieved. With installation options according to figure 2, an
accuracy of ±10% is achieved. Casing leakage is according
to ductwork leakage class C (EN 1751).
Commissioning
Maximum measurement deviation is ±10%, even when
the damper i positioned near a T-piece, transition piece
or duct bend. See figure 2, regarding straight duct length
demands. The pressure differential can be read and the
airflow can be determined from K-factors (COP) or com-
missioning diagrams by using the fixed measuring points.
A label containing k-factor table and commissioning dia-
grams is attached to one of the measuring points at deli-
very. When commissioning, set desired throttling using a
screwdriver or ring spanner. See table "Ring spanner sizes".

Maintenance
The damper is maintenance-free. Whenever needed, clean
the damper by vacuum-cleaning with a brush nozzle.
When cleaning a duct, first note what position the damper
is set to before opening fully. Restore the setting of the
damper after cleaning.
