5.4.3 Installing the reversing
device
Î See Fig. 5-5
Note
The reversing device (for Type 4u) can only
be attached to the valve when the stem is ful-
ly retracted.
The spring (8) of the reversing device is pre-
tensioned upon delivery over the lever (4)
using a wooden bolt (5) with washer (6) and
coupling nut (7).
Procedure
1. Screw the pretensioned reversing device
to the bottom section of the valve.
2. As the device is pretensioned, carefully
unscrew the coupling nut (7) and remove
it from the reversing device together with
the wooden bolt (5) and washer (6).
3. Adjust the highest possible set point at
the set point adjuster to cause the pin of
the operating element to retract.
4. Screw the operating element onto the re-
versing device (in place of the coupling
nut (7)).
Note
Keep the wooden bolt and washer for later
use.
They can be used, for example to pretension
the reversing device again if it needs to be
reinstall after disassembly.
