6.1.1
Directly mounting
Before starting the assembly of actuator and slide/valve/flap, observe that the actuator and the
slide/valve/flap are in the same end position, e.g. both in OPEN or in CLOSE position. Furthermore
the operating direction on actuator and slide/valve/flap must be the same.
Put the bottom side of the actuator to the slide/valve/flap that the stem will enter into the octagonal
boring of the shaft of the actuator. If necessary use a appropriate bushing (options), to equalize
differences of the dimension between the stem and the shaft.
Align the actuator to the slide/valve/flap.
Put the actuator onto the stem of the slide/valve/flap until the surface of the actuator cling to the
ISO - flange of the slide/valve/flap. If this operation will be ponderous the shaft of the actuator will
be driven onto the stem of the slide/valve/flap by slightly strokes without any tools.
Fasten the actuator with fit bolts. Observe the maximum depth of the threaded holes of the actua-
tor. Would there be two sizes of hole circles to fasten the actuator, you have always to use the
greater one.
Tighten the screws. Therefore observe the maximum torque of the choused screws.
