STEP 4: CHAIN HOIST DRIVE (OPTIONAL) (N/A FOR L250 MODEL)
Option A
A Position chain hoist assembly on door axle so that the
chain hoist gear engages the ring gear. NOTE: Do not
tighten set screws until tension has been added in Step 16.
B The opening edge of guides should be
inset a very small amount (about 1/8
inch), from the door jamb opening on
each side to minimize the potential
of hitting the guides when enter-
ing through the door opening. Both
guides must be plumb. Note: If jambs
are installed correctly the outside to
outside measurement of guides should
be approximately 1 inch wider than
the curtain width.
C Once both guides have been correctly
positioned, attach them to the jambs
using the appropriate fastener at each
hole location.
