Installation and maintenance
Installation
When positioning the damper, the risk of personal injury must be taken into account. The damper
must therefoe be installed outside the working zone, e.g. at least 2,1 meter above the floor level.
As standard, the pipe connections are equipped with clamp rims. Installation can be carried out in
an optional position, but we recommend horizontal.
Connecting pipe work is to be suspended in such a way that the damper is not subjected to rupturing
forces. These can cause the damper to jam och to get stuck.
Electrical installation
Before starting the electrical installation the damper must be connected to the duct work, otherwise
the connections on the damper should be covered securely. Electrical connection must be carried out
by a qualified electrician.
Before starting up
1. Check that the damper blade runs smoothly. This should be done after the mechanical installation.
2. Check that the damper is opened and closed when intended.
Regular maintenance
The damper is maintenance free. When required, it can be cleaned using a cloth dipped in ethylated
spirits.
Troubleshooting when the damper blade jams or gets stuck
1. The damper needs to be cleaned
2. There are rupturing forces in the pipe system
3. The damper blade is damaged
4. Loose sealings
Service switches or lockable master switches for fans must be turned
off when working with the damper.
