10 Start-up
DANGER!
This FG metal-edge filter is not allowed to be put into
operation until it has been established that the
machine/system in which it is to be installed complies
with the requirements of the applicable EC directives,
harmonised standards, European standards or equivalent
national standards.
DANGER!
Explosion hazard!

Risk of injury to persons or damage to
property.

The FG metal-edge filter must be
completely vented prior to start-up for
use with all media which are capable of
forming explosive gases.

The FG metal-edge filter must be
completely filled with liquid.

Take steps to prevent air pockets.
DANGER!
Danger due to high pressure in the filter!

Risk of injury to persons or damage to property

shown by the arrow (clockwise direction).

Reverse the terminal connections of the gear motor if
necessary.

Screw the cap of the gear motor back on again.
