Adapter Bracket
The 220738A Adapter Bracket, positioned between the motor
and the equipment, raises motor shaft height by 0.75 in.
(19 mm) to match that of previous Modutrol Motor models.
The following applications require this bracket:
• Q607 External Auxiliary Switch.
• Damper linkage applications require added clearance to
allow:
— Crank arm rotation through the downward position.
— Sufficient damper linkage to reach the motor shaft.
• All valve linkages except the Q5001.
NOTE: When the bracket is not used in a replacement
application, the damper linkage requires adjustment
for the new shaft position.
To mount the motor with the bracket:
1.
Mount the bracket to the equipment with existing or stan-
dard bolts.
2.
Using the provided bolts, mount the motor to the bracket
threaded holes. See Fig. 3.
For valve linkage applications (other than the Q5001):
1.
Mount the bracket to the linkage.
2.
Position the motor on the bracket to align the motor shaft
with the linkage.
3.
Attach the motor to the bracket with the four bolts
provided. See Fig. 4.
