C: INSTALLING THE OPERATOR
STEP 2: Raise the Tee Rail so that the Front Idler Bracket and
Front Mounting Bracket align. Insert bolt and tighten nut loosely for
now. Later in the installation, this nut must be tightened securely.
STEP 3 — Sectional Doors and One Piece Doors with Track:
Raise the Opener and rest the Power Unit on a ladder or other sturdy
support. Open the door the full open position. Allow 2" of space
between the Tee Rail and the top section of the door (as shown in the
illustration, below, far left).
STEP 3A — One Piece Doors without Track: Raise the opener
and rest the power unit on a ladder or other sturdy support. Open the
door to the high arc position. Allow 2” of space between the tee rail
and the door (at the high arc position) as shown in the illustration,
below, left. The opener will be angled as shown. This is necessary
for proper operation.
NOTE: Since the Opener will be secured permanently in this
position, open and close the door a few
times to be sure the door does not rub on the
Tee Rail and that you have allowed the
proper clearances before proceeding.
STEP 4: Mount Power Head to Ceiling:
Since there is such variety in ceiling
structures, all the mounting possibilities for
the Power Unit cannot be illustrated here.
The main concern is mounting the Power
Unit securely to the ceiling joists for
operational strength, rigidity and safety.
Although there are a series of mounting slots
provided on the power unit, try to secure
the mounting straps in the slots closest to
the front. Mounting may usually be
accomplished using standard
1-1/4“ perforated steel angle available at most hardware stores. If in doubt about location of, and attachment to, ceiling joists, a
carpenter should be contacted to provide assistance. A cross brace will be necessary if power head is mounted 8” or more from the
ceiling.
STEP 5: Return to the Tee Rail/Front Mounting Bracket and securely tighten the bolt and nut that connect the Tee Rail Front
Idler bracket and the Front Mounting Bracket. (See Step 2, above).
