Equipment Differences from normal Side
Mount Unit.
1) Door Shaft will be split in 2 pieces to allow
installing the drive sprocket on a Chain Coupled
Door. In addition, the shaft pieces will be shortened
on a Direct Couple Door to allow space for the
Operator Output Shaft.
2) The Emergency Hand Hoist is mounted on an
extension shaft that places the Hand Wheel and
Hoist Chain at the edge of the door.
3) Included is a kit for mounting the Hoist with the
extended shaft (Installation Instructions on reverse
side of this instruction).
Installation Differences-Direct Couple.
1) If not closed — fully close the door.
2) Slide a coupling half onto each door shaft and
operator shaft each with a square key .
3) Slide the operator between the door shafts so that
the output shaft is aligned with the two door
shaft halves.
4) Butt the coupling halves together and tighten their
set screws.
5) Roll both halves of the door shaft to remove slack
from the cables and equalize tension on both ends.
They can be held in position using clamps or locking
pliers while the shafts are being coupled together.
Bolt the coupling halves together with flat washers
next to the coupling and lock washers next to
the nuts.
6) Install Hoist Kit. (See Reverse)
Installation Differences-Chain Couple.
1) Slide the door shaft sprocket onto the half of the
door shaft that allows it to be aligned with the
sprocket on the operator output shaft.
2) Slide a coupling half onto each door shaft each with
a square key.
3) Butt the coupling halves together and tighten their
set screws.
4) Roll both halves of the door shaft to remove slack
from the cables and equalize tension on both ends.
Bolt the coupling halves together with flat washers
next to the coupling and lock washers next to
the nuts.
5) Align the door shaft sprocket with the operator
output sprocket and tighten the set screws in both
the sprocket and coupling.
6) Install Hoist Kit. (See Reverse)
