PRE-INSTALLATION CHECKLIST
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.
