Step 5:
After the rear of the operator is suspended, remove the door
support and close the door. Remove the 6mm x 50mm carriage
bolt and nut that was used to temporarily hold the front end of
the rail to the bracket and secure with a 8mm x 25.4mm bolt
and lock nut. Attach the straight portion of the door arm to the
carrier by means of the 10mm x 25.4mm bolt and self-locking
nut already on the carrier. Assemble the angled portion of the
door arm to the door bracket with a 10mm x 25.4mm bolt and
self-locking nut from the hardware bag. This connection should
be made to the top round hole on the door bracket with the
door arm on the
INSIDE
of the angle. (See Fig 13B). Next,
connect the two sections of the arm together with three holes
overlapping using two 8mm x 25.4mm bolts. (Make the nuts
only finger tight at this time).
Step 6:
Release the carrier for manual operation of the door. Swing the
door arm and door bracket forward until the door bracket rests
against the inside surface of the door with the arm attachment
point close to the top edge of the door (See Fig 13B). Note the
position of the outer slide of the carrier on the rail and make a
mark for later reference. Prepare the operator for electrical
operation.
Step 8:
Step 7:
With the disconnect still in the release position, start the opera-
tor in the closing direction (carrier forward) by means of the
pushbutton and allow it to stop on the DOWN limit setting.
Should the position of the inner carrier slide not coincide with
the position of the outer slide determined in
STEP 6.,
it will be
necessary to re-position the DOWN limit cam so that the outer
slide of the carrier stops as close as possible to this point.
Move the DOWN limit roller assembly on the chain toward the
door if more travel is needed; toward the operator head to re-
connect.
When the
DOWN
limit position of the inner carrier slide and the position of the outer slide determined as in
STEP 6,
coincide as closely as possible following the
DOWN
limit adjustment, re-connect the carrier slides. Swing the door arm up
forward until the door bracket rests against the inside face of the door. If the point of attachment of the door arm on the
door bracket is within 25.4mm of the top edge of the door, check vertical alignment of the door arm then mark the door for
mounting holes. Use centre hole and bottom of the lower slot. Drill two 6mm holes and secure the bracket to the door with
the carriage bolts provided. (NOTE: When drilling these holes, make sure that the drill, exiting through the front surface of
the door, does not damage any overlapping trim.) Tighten the two 8mm x 25.4mm nuts and bolts which hold the two
sections of the door arm together.
Step 9:
Again, release the carrier for manual operation. Using the pushbutton, run the carrier to its fully open (rear) position.
Manually, raise the door to its fully open position and note the relative positions of the inner and outer carrier slides. If the
two halves of the carrier do not coincide exactly, re-position the UP limit roller assembly on the chain until the inner slide
stops, during electrical operation, just AHEAD of the outer slide (toward the door). Do not permit the inner slide to attempt
to travel beyond the maximum rearward travel of the outer slide with the door in the fully open position.
