9.1
Installation
DANGER!
Explosion hazard!
Risk of injury to persons or damage to
property.
•
Check the conductivity between all
components!
•
Note the maximum permissible resistance:
R < 10
Ω
.
•
Make sure that earthing is provided by the
customer.
It must be possible to remove the filter insert
in order to carry out maintenance work.
•
Prepare a suitable seat on which to mount the filter (e.g.
supports, see data sheet).

Connect the pipes.
Pressure relief
•
Design measures must be incorporated to prevent
inadmissible excess pressure on the dirty side.
•
Install a pressure relief device if necessary.
9.2
Installing the pipes and selecting the pump
•
Check the pump characteristic.
•
Make sure that the pump suction opening is positioned
well below the liquid level.
•
Ensure a minimum inlet pressure of 1.0 bar.
9.3
Backflushing
The maximum permissible static pressure for the AF 112 G2
is a pressure rating of PN 16.
The normal operating pressure for backflush filters with
internal pressure cleaning is between 1 and 4 bar. Suitable
devices, such as throttles, pressure reducing valves or
locks, must be installed to ensure reliable operation at
higher pressures. At high operating pressures the backflush
volume increases.
