NOTE:
The Tee Rail/Belt Assembly is packaged separately
from the Power Unit. The Inner Trolley half, Front Idler
Sprocket, Belt, and Limit Cams are assembled on the Tee Rail
at the factory. Follow the steps outlined below to complete
assembly prior to installation. Refer to the Component
Identification illustrations on page 3.
STEP 1:
Unpack the Power Unit box, separate and verify
the items shrink wrapped on the cardboard packaging (see
Component Identification illustrations on Page 3). Protect the
Power Unit cover from scratching during assembly by placing
it on cardboard. Remove the two 5/16"-18 washered nuts and
the Belt Retaining Block and save them for re-installation
later, see Illustration A.
STEP 2:
Unpack and position the Tee Rail/Belt Assembly
near the Power Unit. Locate the Trolley Outer Half and the
operator Installation Hardware Packet (see Component
Identification illustrations on Page 3).
STEP 3:
Slide the Trolley Outer Half onto the Tee Rail/Belt Assembly with the
arrow on theTrolley pointing toward the Door (Front Idler)
, see Illustration B.
Lock the Trolley
Outer Half onto the
Inner Half .
STEP 4:
Remove and
discard the tape used to
keep the belt looped at the
one end on the rail
assembly during shipping.
Position the trolley assembly to be
at approximately the mid point on the
rail.
STEP 5:
Loop that end of the belt around the Idler and
Drive Sprocket on top of the Power Unit and then position the Tee Rail on
the studs, see Illustration C. Secure with the two nuts removed in Step 1.
Slightly tension the belt by tightening the outer nut on the belt tension spoon, this will begin to compress the blue
spring, see Illustration D.
Remove and discard
the tape
at each end of the Tee Rail
Assembly. After
double-checking the belt's
alignment with the Drive
Sprocket on the Power Unit
and Front Idler Wheel on the
opposite end of the rail
assembly, fully tension the belt
by tightening the outer nut on
the belt tension spoon until
approximately 1 inch of
threads is showing on the rod,
making sure the belt does not
twist.
When correctly
adjusted, the belt should
show no droop and be
approximately 1/2" above the
base of the Tee Rail.
