DAMPER LINKAGES

A 220738A Adapter Bracket is packed with replace-
ment motors. Use of this bracket is optional for many
damper applications but may be needed in damper appli-
cations 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 will have to
be adjusted 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 sepa-
rately (see Accessories).
For detailed instructions on the assembly of specific
linkages, refer to the instruction sheet packed with each

motor and the equipment, raises the shaft height ptthe-
M9484 motor by 0.75 inch to match that of the M941 motor.
This is required on all valve linkage applications, Q607
External Auxiliary Switch applications, and on some
damper linkage applications (either to provide clearance
for the crank arm to rotate through the downward position,
or to allow the damper linkage to reach the shaft).
To mount the motor with the bracket:
1. Mount the bracket to the equipment with existing or
standard bolts.
2. Mount the motor to the bracket using the bolts pro-
vided into the threaded holes of the bracket (see Fig. 3).
For valve linkage applications, the bracket should first
be mounted to the linkage (see Fig. 4). The bracket then
provides a convenient base on which the motor can be
positioned. After the motor shaft is aligned to the linkage,
it can then be attached to the bracket with the 4 bolts
provided. These bolts go through the inner set of holes in
the motor flanae and into the threaded holes of the bracket.

to the bracket using the bolts provided with
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 the maximum required distance when the motor
moves through its full stroke.
2. With modulating control, maximum damper
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.
