Test the Wi-Fi Signal Strength
Make sure your mobile device is connected to your Wi-Fi network. Hold your mobile device in the place where your
door operator will be installed and check the Wi-Fi signal strength.
Check Signal Strength. If you see:
• Move your router closer to the door operator
to minimize interference from walls and other
objects
• Buy a Wi-Fi range extender

Check the Door
To prevent possible SERIOUS INJURY or DEATH:
ALWAYS call a trained door systems technician if door binds, sticks, or is out of balance. An unbalanced
l
door may NOT reverse when required.
NEVER try to loosen, move or adjust door, door springs, cables, pulleys, brackets or their hardware, ALL of
l
which are under EXTREME tension.
Disable ALL locks and remove ALL ropes connected to door BEFORE installation and operating door
l
operator to avoid entanglement.
DO NOT install on a one-piece door if using devices or features providing unattended close. Unattended
l
devices and features are to be used ONLY with sectional doors.
To prevent damage to door and operator:
ALWAYS disable locks BEFORE installing and operating the operator.
l
ONLY operate door operator at 120V, 60 Hz to avoid malfunction and damage.
l
Before you begin:
1. Disable locks and remove any ropes connected to the 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 operator 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.
