Table 3 - Usability
General information
o
During mounting or installation, there is a risk of in-
juries. To avoid injuries, personal protective equip-
ment (PPE) must be worn.
o
Smoke extraction dampers must be installed such
that external forces do not impair their functioning.
During mounting it may be required to provide rein-
forcements for the housing or the like. The require-
ment of statically load-bearing lintels may have to be
taken into consideration.
o
Improper transport/handling may result in dam-
age/functional impairment. In addition to that, the
film of the transport packaging must be removed
and the delivery inspected for completeness.
o
In storage, smoke extraction dampers must be pro-
tected from dust, dirt, moisture and the effects of
extreme temperatures. They must not be exposed to
direct effects of the weather.
4)
in connection with ceiling frame DR-S
5)
in connection with on-site suspensions
6)
in connection with on-site fastening frames and suspen-
sions
o
The smoke extraction dampers must be protected
from dirt and damage. After installation is complete,
any dirt must be removed immediately.
o
Enough space must be provided for installation, mor-
tar lining, etc.
o
Carry out a functional check of the smoke extraction
damper before and after mounting and ensure ready
access.
o
Electrical installations or work on electrical compo-
nents may only be carried out by skilled electricians.
The supply voltage must be switched off when per-
forming this work.
o
Always check whether the housing needs to be ex-
tended on the b side (MS) for the corresponding in-
stallation situations (e.g. the thickness of the sup-
porting structure and a possible connection to the
smoke extraction duct must be considered).
