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 | 104372 | |
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 | SECTIONAL DOORS AND ONE- | ONE PIECE DOORS |
proper clearances before proceeding. | ||
