INSTALLATION STEPS
1. Install Main Door Pulleys (left and right) over the Top
of the Door on each side of the Door Beam (Part #10).
2. Next mount the Winch Mechanism to the Front Panel
Lower Beam (Part #13A).
3. Slide Bottom Door Dropping Tube (Part38) into the
bottom horizontal fabric pocket on the Door Cover (Part
#31A). Then slide the six remaining Door Dropping
Tubes (Part #37) into the remaining horizontal fabric
pockets in the Door Cover
。
4. From the bottom of the door tracks(11,12,12A), gently
raise and slide one door dropping tube(37,38) into the
tracks. And then feed the other remaining door dropping
tubes(37,38) into the door tracks.
5. Next install the steel wire that leads from the bottom
of the door dropping tubes to the door winching
assembly. Take one of the Steel Wires in the Door kit,
and feed down from the top of the Door track to the
Bottom Door Tube Dropping Tube (#38) on the right
hand side of the door (facing from the inside). When
the steel wire goes down though the hole in the Bottom
Dropping Tube, tie a knot in the steel wire so that it
cannot pass back up through the hole.
6. From the Winch Assembly route leading end of the
Longer Steel Cable through the Upper Roller of the
double the pulley near door track and then through the
Single Roller on the door track farthest from the Winch
Assembly.
Then down through the Bottom Door Dropping Tube
(#38).When the steel cable goes down though the hole
in the Bottom Door Dropping Tube, tie a knot in the
steel cable. Door can now be operating the Winch
Assembly. Raise and lower the door several times to be
certain door tube ends are not binding on track..
Lubricate if necessary.
