Installation
STEP 6 Install the light bulb

Use ONLY A19 incandescent (60W maximum) or compact fluorescent (23W maximum) light
l
bulbs.
DO NOT use incandescent bulbs larger than 60W.
l
To prevent damage to the opener:
DO NOT use compact fluorescent light bulbs larger than 23W (100W) equivalent.
l
DO NOT use halogen bulbs.
l
DO NOT use short neck or specialty light bulbs.
l
1. Press the triangular release buttons and swing the lens open.
2. Insert an A19 incandescent (60W maximum) or compact fluorescent (23W, 100W equivalent)
light bulb into the light socket.
3. Swing the lens shut until triangular buttons click into place.
NOTE: Do not use halogen, short neck, or specialty light bulbs as these may overheat the unit. The use
of LED bulbs may reduce the operating range or performance of your remote controls.
STEP 7 Attach the emergency release rope and handle
To prevent possible SERIOUS INJURY or DEATH from a falling garage door:
If possible, use emergency release handle to disengage trolley ONLY when garage door is
l
CLOSED. Weak or broken springs or unbalanced door could result in an open door falling
rapidly and/or unexpectedly.
NEVER use emergency release handle unless garage doorway is clear of persons and
l
obstructions.
NEVER use handle to pull door open or closed. If rope knot becomes untied, you could fall.
l
1. Insert one end of the emergency release rope through the handle. Make sure that "NOTICE" is
right side up. Tie a knot at least 1 inch (2.5 cm) from the end of the emergency release rope.
2. Insert the other end of the emergency release rope through the hole in the trolley release arm.
Mount the emergency release within reach, but at least 6 feet (1.83 m) above floor, avoiding
contact with vehicles to prevent accidental release and secure with a knot.
NOTE: If it is necessary to cut the emergency release rope, seal the cut end with a match or lighter to
prevent unraveling. Ensure the emergency release rope and handle are above the top of all vehicles to
avoid entanglement.
