CHANGING HAND (ROTATION OF THE MOTOR)
9.1.
Changing Hand in the Field:
Reroute the power cord (and strike wire if applicable) so it exits the unit on the
hinge side of door. Reverse the two motor leads on M1 and M2 so the motor will run in the opposite direction.
To ensure correct positioning of the motor leads, perform the following steps:
9.1.1.
Hold unit to new door or jamb position and note which motor lead (M1 or M2) is closest to the hinge
side of door.
9.1.2.
Place unit on table and, if necessary, carefully remove the lead wires and reroute the blue wire to the
motor lead position closest the hinge side of door. This also positions the blue wire in the motor lead
position closest to the motor. The black wire then positions to the other lead.
9.1.3.
When converting from door mount to jamb mount, refer to
Lever Arm Adjustment
and perform the
following steps:
9.1.3.1.
Use any commonly available threadlocker, such as LOCTITE
®
,
on the two clutch arm hub set
screws so they will not loosen during operation.
9.1.3.2.
Use threadlocker on the adjustment arm nut so it will not loosen during operation.
9.1.4.
Once the lead wires are confirmed in the correct position, follow the proper installation guide to mount
the opener.
