Maintenance and cleaning
WARNING!
Risk of explosion!
Ignition sources, such as sparks, open flames or
hot surfaces, can lead to explosions in an area
with potentially explosive atmospheres.
–
Get written permission before you start
working in an area with potentially explosive
atmospheres.
–
Do not carry out any work in a potentially
explosive atmosphere.
To remove any potentially explosive atmos-
phere, purge the system with fresh air
before you work on it.
–
Use only tools that have been approved for
use in areas with potentially explosive
atmospheres.
Failure to comply with these safety notes may
lead to an explosion.
Maintenance
It is the system owner's duty to set up a mainte-
nance schedule, taking the actual operating condi-
tions (contamination, operating time etc.) of the
ventilation system into consideration.
Important:
Do not lubricate the bearings of the
damper blade.
Maintenance jobs to be carried out regularly:
Visually check the controller for contamination,
damage and corrosion. Remove contamina-
tion; if the controller has been damaged, or if
there is any corrosion, replace the controller.
Check the fixing of the controller and of the
connected ductwork.
Check the equipotential bonding.
