Installation – Commissioning – Maintenance
Installation
Size of opening, see the dimensions of the connecting
duct. Place the mounting frame in the mounting plate
and insert it into the connecting duct. Secure it with blind
rivets from the inside. Be careful when positioning the
blind rivets so that they will not be in the way when you
fit the exhaust register in the mounting frame. Rotate
the diffuser into the bayonet fasteners of the mounting
frame.
After you have finished commissioning to exhaust register,
secure the protective screen using the steel blind rivets
supplied. See Figure 1.
Figure 1. Installation.
Commissioning
Rotate the inner cone clockwise (-) to increase the pres-
sure drop and counterclockwise (+) to decrease it. Lock
the position of the cone by tightening the lock nut on the
rear side of the exhaust register.
Commission the exhaust register by measuringthe pres-
sure or the airflow. For pressure measurement, use a
so-called "measuring hook" and for airflow measurement
use a commonly marketed airflow meter. See Figures 2
and 3.
The rated coefficient of performance (K-factor) is speci-
fied on the identification label of the product and in the
relevant commissioning instructions at www.swegon.com.
Maintenance
The exhaust register can be cleaned, if necessary, using
lukewarm water with dishwashing detergent added or by
vacuum cleaning using a brush nozzle. The duct system
can be reached for cleaning by turning the exhaust regis-
ter out of its mounting frame after you have removed the
protective screen.
