1. Place the crank in the middle position and remove the clamp.
2. Rotate the crank downward so the plug presses the sealing element upwards
from the valve body.
3. Remove the cap (3) and loosen the screws (7+10) and remove the washer (4) by
sliding it sideways
Now remove the crank from the sealing element.
4. Unscrew the valve plug from the actuator spindle.
This is done by inserting a screwdriver into the spindle and using a 17mm spanner
at the valve plug.
5. Remove the diaphragm and disc.
The lip-seal and bushing in the sealing element can be replaced if necessary (see
section 5.5 Manual actuator bushing and lip seal replacement)

1. Place the crank in the top position (so the valve plug is upwards) and remove the
upper and lower clamps.
2. Lift away the upper valve body with the actuator.
3. Remove the cap (3) and loosen the screws (7+10) and remove the washer (4) by
sliding it sideways.
Now remove the crank (1) from the sealing element (17).
4. Unscrew the valve plug from the actuator spindle.
This is done by inserting a screwdriver into the spindle and using a 17mm spanner
at the valve plug.
5. Remove the upper valve body and the valve seat (28).
6. Remove the diaphragm and disc. The sealing element can be difficult to remove
from the valve body, but if this is the case then use the valve plug (without the valve
seat (28)) to press it out of the valve body.
The lip-seal and bushing in the sealing element can be replaced if necessary (see
section 5.5 Manual actuator bushing and lip seal replacement)
