Installation
•
FK90 fire dampers, series FK120, must be installed based
on the instructions in this user manual. The technical
regulations and national statutory regulations must be obser
-
ved during installation.
In Germany, this means the “Technical Building Regulations”
(VV TB) and the "Guideline on Fire Protection Requirements
Pertaining to Ventilation Systems" (Lüftungsanlagenrichtlinie -
LüAR).
FK90 fire dampers meet these requirements and generally
recognised technical regulations.
•
Electric wiring
must be installed by the customer.
•
Potential equalisation conductors
to bridge flexible
connection pieces on fire dampers can be fastened
with metal screws if they are made of copper up to a
cross-section of 6 mm² or made of aluminium.
•
Fire dampers in
potentially explosive atmospheres
must
be grounded in accordance with regulations.
Functional testing and servicing
•
Fire dampers must be serviced by the owner and tested
periodically to ensure they are functioning correctly.
The intervals largely depend on the system operation. Rele
-
vant regulations should be followed.
•
FK90 fire dampers, series FK120, are maintenance-free due
to fully enclosed components, corrosion-resistant materials
and precise manufacture.There is no need for regular clea
-
ning and lubrication, which would otherwise be necessary.
•
Functional tests on FK90 fire dampers, series FK120, are
generally limited to a release and re-opening.This can be
performed remotely with electric actuators.
•
Repairs or service work are required in the event of malfunc
-
tions.Original spare parts must be used for this.
•
Cleaning work required in ventilation systems for hygiene
reasons must be performed in an operation-dependent
manner, and also includes the fire dampers.
