Installation
STEP 6 Install the light bulb
To prevent possible OVERHEATING of the endpanel or light socket:
DO NOT use short neck or specialty light bulbs.
l
DO NOT use halogen bulbs. Use ONLY incandescent.
l
To prevent damage to the opener:
DO NOT use bulbs larger than 100W.
l
ONLY use A19 size bulbs.
l
1. Install a 100 watt maximum light bulb in the socket. Light bulb size should be A19, standard neck
only. The light will turn ON and remain lit for approximately 4-1/2 minutes when power is
connected. Then the light will turn OFF.
2. Insert bottom lens tabs into slots on chassis. Tilt towards chassis to engage top tabs, then drop
down gently into place (see illustration).
3. To remove, depress both top lens tabs. Tilt lens slightly outward and down, then pull out to clear
bulb. Use care to avoid snapping off bottom lens tabs.
4. Use A19, standard neck garage door opener bulb for replacement.
NOTE: Use only standard light bulb. The use of short neck or speciality light bulbs may overheat the
endpanel or light socket.
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.
