tion
1. Move actuator manually to intermediate position or to sufficient distance from
end position.
2. Depending on the version: Unscrew threaded plug [1] with seal [2], protective
cap [4] or stem protection tube [6].

The direction of rotation is correct if the actuator moves in direction CLOSE
and the hollow shaft in clockwise direction, or the stem moves downward.
4. Correctly fit/screw on threaded plug [1] with seal [2], protective cap [4] for stem
protection tube [6], fasten thread.
