INSTALLATION
Installation
WHEN INSTALLING THIS PRODUCT...
1. Read these instructions carefully. Failure to follow
them could damage the product or cause a hazardous
condition.
2. Check the ratings given in the instructions and on
the product to make sure the product is suitable for your
application.
3. Installer must be a trained, experienced service
technician.
4. After installation is complete, check out product
operation as provided in these instructions.
CAUTION
!
1. Disconnect power supply before beginning
installation to prevent electrical shock and
equipment damage.
2. Never turn the motor shaft by hand or with a
wrench—this will damage the motor.
3. Always conduct a thorough checkout when
installation is complete.
LOCATION
Install the Modutrol Motor in any location except where
acid fumes or other deteriorating vapors might attack the
metal parts, or in atmospheres of escaping gas or explosive
vapors. Motors are rated for ambient temperatures between
-40° F [-40° C] and 150° F [ 66° C].
Allow enough clearance for installing accessories and
servicing the motor when selecting a location (see Fig. 1).
When mounting the motor outdoors in an upright position,
use liquid-tight conduit connectors and wiring box to provide
NEMA 3 weather protection. When mounting the motor
outdoors in other than an upright position, use the 4074ERU
Weatherproofing Kit and liquid tight conduit connectors to
provide NEMA 3 weather protection.
MOUNTING
Always install motors with the crankshaft horizontal.
Mounting flanges extending from the bottom of the motor
housing are drilled for 1/4 inch [6.4mm] machine screws
or bolts.
M7161A,B; M7164A,B and M7184A Motors are shipped from the factory in the closed position (at the limit of
counterclockwise rotation as viewed from the power end of
the motor). M7161G and M7164G are shipped in the open
position (at the limit of clockwise rotation as viewed from the
power end of the motor). See Fig. 2.
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, with the bolts provided, through the threaded holes in the bracket. See Fig. 3.
For valve linkage applications, see Fig. 4, the bracket should
first be mounted to the linkage so the bracket can provide a
convenient base for positioning the motor. After the motor
shaft is aligned, it can then be attached to the bracket with the
four bolts provided. The bolts are inserted through the inner
set of slots on the motor flange and into the threaded holes of
the bracket.
DAMPER LINKAGES
A 220738A Mounting Bracket is packed with replacement motors. Using this bracket is optional for many
damper applications. The bracket may be needed in damper

ADAPTER BRACKET
The 220738A Adapter Bracket, positioned between the
