PRE-INSTALLATION CHECKLIST
Check the following items before assembling the opener:
•
Identify the door type: sectional door or one-piece jamb door.
•
Ensure your garage door is balanced and is not sticking or binding.
•
Here is how to check the door balance:
◊
From outside the garage, slowly open the door all the way and close it all the way –
DOOR SHOULD NOT BIND OR RUB.
◊
Raise the door halfway up – DOOR SHOULD STAY IN PLACE, SUPPORTED ENTIRELY BY
ITS SPRING.
•
IMPORTANT: IF THE GARAGE DOOR FAILS EITHER OF THESE TESTS, HAVE A QUALIFIED
GARAGE DOOR PROFESSIONAL ADJUST OR REPAIR THE DOOR.
•
If the garage door is lightweight (made with frame and skin, not solid), it must be braced
or reinforced before installing the opener (including the door frame). Check with a qualified
service professional for a door reinforcement kit.
•
If you do not have an access door in addition to the garage door, you should install an
emergency key release kit.
•
If your door is more than 7' (2.1 m) high, you will need a rail extension kit (sold separately).
•
With the garage door closed, check alignment of door and garage floor. The gap, if any,
should be no more than 1/4" (6 mm). If the gap is larger than this, repair floor or door
before installing opener.
