Preparatory measures

ƒ
Close the ball valve.
ƒ
Unscrew the plug screw from the ball valve.
Installation (see fig. II)
1. Place the O-ring from the attached coupling set (type A or B) on the
mounting pin.
2. Insert the O-ring with the mounting pin into the sensor hole of the ball
valve (turn the mounting pin).
3. Position the O-ring in its final position using the other end of the
mounting pin.
4. Fastening screws
ƒ
Type A (plastic) - put the fastening screw onto the temperature sen-
sor.
ƒ
Type B (brass) - slide the fastening screw onto the temperature sen-
sor and attach the fastening screw with the dowel pin. Press in the
dowel pin completely and remove the mounting pin from the temper-
ature sensor.
5. Insert the temperature sensor with adapter fitting into the ball valve
and tighten fastening screw by hand (2-3 Nm).

4.2 Installation in a pocket

In case of new installations, temperature sensors for nominal sizes DN25
or smaller should only be installed immersed.
This ensures higher measuring accuracy.
