Screw threaded part of compression fitting one or two turns by hand
into connecting piece.
In case of a longer sensor probe push it partly into the pipe then
screw thread firmly into connecting piece (hexagon SW27).
!
Always avoid bending of the probe during screwing.
Carefully slide probe so that the center of the chamber head is
placed at the optimum measuring position in the middle of the pipe.
Tighten compression fitting nut slightly by hand so that sensor is
fixed.
Turn sensor manually at its enclosure into required direction and
precise position while maintaining immersion depth.
!
Angular deviation should not be greater than
3° relative to
ideal position.
Hold sensor and tighten compression fitting nut by turning the fork
wrench (SW17) a quarter of a turn.
Recommended torque: 10 … 15 Nm
Check the set angular position carefully, for example by means of a
spirit level at the hexagonal part of the sensor enclosure.
Make sure to close the safety chain before pressure is applied. The
chain lock must be hung up in a way to avoid sagging of the chain.
