PRE-INSTALLATION CHECKLIST
model no. 046-0265-2 | contact us 1-800-689-9928
6
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.
