INSTALLATION INSTRUCTIONS
1.) Start prepping the unit for installation of the electric motor. The limit on this motor
works in the manner of one is fixed while the othe r limit can be set, see figure 1. Power the motor
to make sure it is at the factory limit, which is activated by the set switch on the bottom of the limit
stack. The other limit activates when it is at its full down position. This may need to be set in the
field when installing the motor. To set the limit, loosen the screw when the motor is in the down
position. Then turn it until it activates the limit switch and retighten the limits together. Once this
is done, run the unit up and down to check for any issues. Th e red wire in the four wire plug is the
down wire and the black wire is the up wire.
