DIRECT COUPLING MOUNTING
Figure 4, page 8 illustrates several positions suitable for
mounting the operator including center mount with direct
coupling to the torsion shaft. Direct coupling may also be
used in a side mount installation. Operators intended for
direct coupling require an internal speed modification and
must be ordered from the factory.
Refer to Figure 2, page 6 and Figure 5, page 9 and Figure 6,
Page 10 for the location of the operator mounting holes.
IT IS ESSENTIAL THAT THE OUTPUT
SHAFT OF THE OPERATOR AND THE
DOOR SHAFT BE CAREFULLY ALIGNED.
MISALIGNMENT OF THE SHAFTS WILL
CAUSE EXCESSIVE STRESS AND WEAR.
Raise the operator to a position which brings the door and
operator shafts into alignment and connect them together
with the flange coupling supplied with operator. Support the
other end of the operator jackshaft from the ceiling with a
chain or rope. Holding the operator in a vertical position,
carefully measure the distance from the operator mounting
plates to the wall. Lower the operator to the floor and
construct a secure mounting surface using the dimension
measured in the previous step. Again raise the operator to its
mounting position and re-connect the shafts. Mark the
mounting slots in the support structure, drill and securely bolt
the operator into place.
BEFORE PROCEEDING WITH THE
OPERATOR INSTALLATION AND
SETTINGS, MAKE A FINAL CHECK FOR
TIGHTNESS OF ALL MOUNTING
HARDWARE.
CHAIN HOIST AND FLOOR DISCONNECT
INSTALLATION
If the operator is furnished with a chain hoist (Model AUH-S), pass
the hand chain over the chain wheel and through the chain guides
on the operator clutch shaft (opposite end from the large pulley).
Fasten the ends of the chain together by opening and re-closing one
link using two pairs of pliers. If the chain is too long (standard
length for 16 foot high doors and below is 26 feet total length of
chain), shorten it to the desired length using the method described
above and discard the unused portion.
Fasten the chain hoist holding bracket furnished with the operator
to the wall approximately four feet from the floor. This bracket is
also used to hold in place the release chain for both the chain hoist
equipped units (Model AUH-S) and floor disconnect models
(Model AUJ-S).
