NOTE: The Tee
Rail/Chain Assembly is
packaged separately
from the Power Unit.
The Inner Trolley half,
Front Idler Sprocket,
Chain, 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 the previous page.
STEP 1: Protect the Power Unit cover from
scratching during assembly by placing it on cardboard.
Remove the two 5/16"-18 washered nuts and save
them for later use.
STEP 2: Position the Tee Rail/Chain Assembly box
near the Power Unit. Open the box and locate the
Installation Hardware Packet.
STEP 3: Locate the Outer Trolley half (packaged
with the Power Unit) and slide it onto the Tee Rail/
Chain Assembly with the arrow on the Trolley
pointing toward the door (Front Idler).
STEP 4: Using a 1/2" wrench, loosen the outer nut
on the Chain Tension Bracket until it is at the end of
the threaded rod. Remove and discard the small
"S" hook used to keep the chain tight during
shipping.
STEP 5: Loop the chain around the Idler and Drive
Sprocket on top of the Power Unit and then position
the Tee Rail on the studs. Secure with the two nuts
removed in Step 1.
Slightly tension the Chain by tightening the outer nut
on the Chain Tension Bracket. Remove and discard
the tape at each end of the Tee Rail Assembly. After
double-checking the Chain's alignment with the Drive
Sprocket and Front Idler Wheel, use the inner and
outer adjusting nuts on the Chain Tension Bracket to
adjust the chain to the proper tension, making sure the
chain does not twist. When correctly adjusted, the
Chain should show no droop and
be approximately 1/2" above the
base of the Tee Rail.
