NOTICE
Unsuitable / incorrect filter element
The medium is not filtered
►
Use only filter elements with the type code suffix -KB
(for example:
1300 R 003 BN4HC /
-KB
)
Depending on the version, the unit has an optical clogging indicator (2) (red/green) or a
scale in the filter cover. The version with change-over may have an optional differential
pressure indicator (1).
Change the filter element as soon as the clogging indicator or differential pressure
indicator is in the red area.
The clogging indicator may respond briefly when there is a cold start, if a higher back
pressure arises due to low temperatures and the resulting high viscosity. With electrical
displays, a suitable time relay should be provided in the local controller in order to
suppress unnecessary malfunction messages.
