12 MOUNTING
12.1 FACTORY PRE-ASSEMBLY OF COMPLETE MONITORING UNITS
If a complete monitoring unit consisting of a liquid sensor, universal filter or flow chamber and electronic
controller is ordered as a complete unit, the sensor is mounted as far as possible in the corresponding
mounting hardware at the factory.
For transportation, the sensor
LA1S of the universal filters F...-...-D is pre-assembled. The LA1S sensor
needs only to be hand-tightened with the GL25 union nut in the lower GL connection of the filter by
turning it to the right.
N O T E !
Please check before assembling that the clamping ring GL25-12 of
PTFE/silicone is not defect and is placed on the sensor, the white PTFE
surface pointing to the viewer (medium side). Only then, the necessary leak-
proofing is guaranteed.
The sensor
LA25S needs to be screwed with the pre-assembled
1/4“ NPT fitting into the thread of the
stainless steel filter body by using a Teflon tape.
If sensors are supplied with a flow chamber, they are pre-assembled.
