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 wo 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.
Sectional Door
One-piece Door
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.
