applications requiring the crank arm to rotate through the
bottom plane of the actuator. If the bracket is not used in a
replacement application, the damper linkage must be ad-
justed to the new shaft position.
The motor comes without a crank arm. The crank arm is
included in the Q605 Linkage or may be ordered separately
(see Accessories).
For detailed instructions on the assembly of specific
linkages, refer to the instructions packed with each linkage.
In general, however, check the following points of operation
when installing a motor and linkage:
1. Linkages for valves and louver type dampers should
be adjusted so that the damper or valve moves through only
Fig. 3—Mounting motor with an adapter bracket. The bracket is first mounted to the equipment with standard
bolts. The motor is then mounted to the bracket using the bolts provided that thread into the bracket holes.

the maximum required distance while the motor moves
through its full stroke.
2. With modulating control, maximum damper opening
should be no more than 60°. Little additional airflow is
provided beyond this point.
3. The motor must be stopped at the end of its stroke by
the limit switch and must not be stalled by the damper or
valve. The motor will be damaged if it is not permitted to
complete its full stroke.
4. Do not exceed the motor ratings in any installation.
5. Do not turn motor shaft manually or with a wrench—
this will damage the motor.
