Starting strainer
In case of intake from a closed piping system, a starting strainer or a lter housing •

order, this is included in the scope of supply.
This protects the machine against contamination and from foreign particles that •
are carried into the intake ow.
The resistance of the starting strainer / lter element is to be monitored.•
The maximum resistance of - 45 mbar must not be exceeded.•
If the strainer remains clean after approximately 500 operating hours, it can be •
dismantled and replaced by the supplied adjusting ring.
The lter element is to be checked or replaced according to the respective speci-•
cations of the ‘intake lter’ in the maintenance plan.
The starting strainer consists of ne-meshed gauze with mash size of 0.5 mm with •
a perforated sheet according to DIN 24041 R 6.3-8.
