12 MOUNTING
12.1 PRE-ASSEMBLY AT WORKS IN CASE OF COMPLETE CONTROL UNITS
In case you order a complete control unit consisting of liquid sensor, universal filter or flow chamber
and electronic controller, the mounting of the sensor into the respective installation device is effected
at works as far as possible.
For transportation, the sensor LA 1S of the universal filters F.-..-D is pre-assembled. The only thing
left to do is to mount the sensor LS 1S hand-tight by clockwise rotation of the red union nut GL25 into
the below GL connection of the filter.
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 LA 25S is to be screwed with the pre-
assembled G1/4“ fitting into the thread of the
stainless steel filter body by using a tape of Teflon.
If the sensors are delivered in connection with a flow chamber, both are completely pre-assembled.
