5 MOUNTING
5.4 Mounting the sensor
1. Stop the flow.
2. Depressurize the system.
3. Empty the pipe in which the sensor is to be installed.
4. Install the process connection adapter or T-piece at the desired installation
location and ensure that the interfaces are sealed.
5. Install the sensor in the process connection adapter or in the T-piece (see
“5.5 Mounting the process connection adapter” and “5.7 Mounting in a T-piece” ).
IMPORTANT
Leak
• When sealing the process connection and pipe, take into account the operating pres-
sure so as to select the correct sealing method.
5.5 Mounting the process connection adapter
Only use original adapters from SICK. These are available as accessories
(see “14 Accessories” on page 66 ).

Process connection
1. Insert the probe of the sensor into the process connection adapter and adjust the
adapter to the correct height (see “5.1 Installation conditions” ).
2. Hand tighten the coupling nut until the probe can no longer be turned by hand or
moved axially in the connection.
3. Mark the coupling nut in the 6 o’clock position.
4.
Hold the process connection with an open-end wrench (width across flats 27) and
tighten the coupling nut 1 1/4 turns to the 9 o’clock position. For this purpose, use
an open-end wrench with a width across flats of 16.

5.6 Removing the process connection adapter
CAUTION
Print
Always depressurize the system. Stop the flow and drain the pipe before removing the
sensor.
To remove the process connection adapter from the sensor probe:
1. Before removing the adapter, mark the pipe on the outer edge of the coupling nut.
Draw a line across the flat surface of the coupling nut and the union body.
2. Use this mark to reattach the coupling nut to the original position when remounting
the adapter.
3. Insert the probe with the assembled cutting ring into the fitting body until the front
cutting ring is seated on the fitting body.
4. Hold the fitting body while tightening the coupling nut to the old position (marked
on the pipe and flat surface) with a wrench. At this point, the resistance increases
noticeably. Tighten the coupling nut slightly.
