Attaching parts to the equipment
Important!
Incorrect assembly can damage measuring
equipment.

Make sure that assembly is performed
by specialist personnel.
 Only apply the tool to the hex nut of
the fastening.

® 217.

Screw the thermometer onto the hex nut of the
right-hand connection on the body using a
size 19 open-ended spanner.

Tighten the thermometer fastening to a torque
of 64 Nm.
To attach the pressure gauge (9), proceed as
follows:

Remove the screw plug and sealing ring from
the left-hand connection (20).

Wind PTFE sealing tape (19) tightly around the
thread of the pressure gauge.

Screw the pressure gauge onto the hex nut of
the left-hand connection (20) on the body using
a size 14 open-ended spanner.

Tighten the pressure gauge fastening to a
torque of 65 Nm.
 Push the adjusting key from underneath up into
the hole of the adjuster as far as it will go.
