NOTE: For detailed information, see Technical
Instructions 155-517P25.
Caution Notations
CAUTION:
Equipment damage may occur
if procedures are not followed
as specified.
Installation
Cover Removal
Use a Phillips screwdriver to loosen the two screws
on the actuator cover corners. See Figure 1.
Lift the screws and raise the cover. See Figure 2.
Figure 1. Figure 2.
Rotational Direction Verification
Actuator model numbers that end with “R” are
factory configured for clockwise (cw), minimum to
maximum rotation when facing the gear end of the
actuator, or counterclockwise (ccw) rotation when
facing the other end of the actuator. The gear end of
the actuator is the side opposite of the visual
position indicator.
Actuator Mounting
SQM5… actuators can be mounted in any
orientation. Optional base mounting brackets are
available.
SQM5… actuators can also be face-mounted using
self-tapping screws in combination with the various
holes on the face of the actuator gear end.
Switch Adjustment
SQM5…actuators are factory-wired with Switch I
(maximum), Switch II (fully closed/economy position)
and Switch III (minimum/low-fire). The individual
switch cams I, II, and III are factory set to 90°, 0°
and 10°, respectively. See Figures 3 and 4.
