INSTRUCTIONS FOR INSTALLATION, USE AND MAINTENANCE
Commissioning and operation
Make sure that the smoke extractor has been instal-
led according to the instructions, and that there are
no foreign objects loose inside. Also check that the
electrical connection has been made according to the
instructions enclosed with the extractor. Then start
the extractor and make sure that the impeller rotates
in the direction indicated by the arrow marked on the
extractor.
Electrical connection
The safety switch of the smoke extractor is installed
on the side of the stack.
The switch and the ex-
tractor must be connected by means of a rubber
cable that complies with the same requirements
as the extractor concerning the burning times.
The SAFEP mounting stack features a channel for
the cable.
NB!
3-phase connection with frequency changer control: Frequency can be changed only
from 50 Hz downward.
The SAFEK smoke extractor is
designed for heat and smoke
venting in case of fire.
SAFEK complies with the
requirements of the Machinery
Directive and it is marked with
the CE mark. VTT has tested the
functionality and it meets the
requirements of class F400 120 in
standard EN 121015-3, appendix C.
