You will need:
lWi-Fi enabled smartphone, tablet or laptop
lBroadband Internet Connection
lWi-Fi signal in the garage (2.4Ghz required)
lPassword for your home network (router's main account, not guest network)

Check the Door
To prevent possible SERIOUSINJURYor DEATH:
lALWAYS call a trained door systems technician if garage door binds, sticks, or is
out of balance. An unbalanced garage door may NOT reverse when required.
lNEVER try to loosen, move or adjust garage door, door springs, cables, pulleys,
brackets or their hardware, ALLof which are under EXTREME tension.
lDisable ALLlocks and remove ALLropes connected to garage door BEFORE
installation and operating garage door opener to avoid entanglement.
lDO NOT install on a one-piece door if using devices or features providing
unattended close. Unattended devices and features are to be used ONLY with
sectional doors.
To prevent damage to garage door and opener:
lALWAYS disable locks BEFORE installing and operating the opener.
lONLY operate garage door opener at 120V, 60Hz to avoid malfunction and
damage.
1. Disable locks and remove any ropes connected to the garage door.
2. Lift the door halfway up. Release the door. If balanced, it should stay in place,
supported entirely by its springs.
3. Raise and lower the door to check for binding or sticking. If your door binds,
sticks, or is out of balance, call a trained door systems technician.
4. Check the seal on the bottom of the door. Any gap between the floor and the
bottom of the door must not exceed 1/4inch (6 mm). Otherwise, the safety
reversal system may not work properly.
5. The opener should be installed above the center of the door. If there is a torsion
spring or center bearing plate in the way of the header bracket, it may be installed
within 4feet (1.2m) to the left or right of the door center. See page 10.

Installation
1 Determine the Header Bracket Location
To prevent possible SERIOUS INJURY or DEATH:
lHeader bracket MUST be RIGIDLY fastened to structural support on header wall
or ceiling, otherwise garage door might NOT reverse when required. DO NOT
install header bracket over drywall.
lConcrete anchors MUST be used if mounting header bracket or 2x4 into
masonry.
lNEVER try to loosen, move or adjust garage door, springs, cables, pulleys,
brackets, or their hardware, ALL of which are under EXTREME tension.
lALWAYS call a trained door systems technician if garage door binds, sticks, or is
out of balance. An unbalanced garage door might NOT reverse when required.
lDO NOT enable the Timer-to-Close functionality if operating either one-piece or
swinging garage doors. To be enabled ONLY when operating a sectional door.
Close the door and mark the inside vertical centerline of the garage door.
Extend the line onto the header wall above the door. You can fasten the header bracket
within 4 feet (1.22 m) of the left or right of the door center only if a torsion spring or
center bearing plate is in the way; or you can attach it to the ceiling when clearance is
minimal. (It may be mounted on the wall upside down if necessary, to gain approximately
1/2" (1 cm). If you need to install the header bracket on a 2x4 (on wall or ceiling), use lag
screws (not provided) to securely fasten the 2x4 to structural supports.
Open your door to the highest point of travel as shown. Draw an intersecting horizontal
line on the header wall 2" (5 cm) above the high point. This height will provide travel
clearance for the top edge of the door.
NOTE: If the total number of inches exceeds the height available in your garage, use the
maximum height possible, or refer to page 11 for ceiling installation.
