INSTALLATION STEP 8 Install the Lights • Press the release tabs on both sides of lens. Gently rotate lens back and downward until the lens hinge is in the fully open position. Do not remove the lens. • Install a 100 watt maximum light bulb in each socket. Light bulb size should be A19, standard neck only. The lights will turn ON and remain lit for approximately 4-1/2 minutes when power is connected. Then the lights will turn OFF. • Reverse the procedure to close the lens. • Use A19, standard neck garage door opener bulbs for replacement. NOTE: Use only standard light bulbs. The use of short neck or speciality light bulbs may overheat the endpanel or light socket. To prevent possible OVERHEATING of the endpanel or light socket: • DO NOT use short neck or specialty light bulbs. • DO NOT use halogen bulbs. Use ONLY incandescent. To prevent damage to the opener: • DO NOT use bulbs larger than 100W. • ONLY use A19 size bulbs.

Secure with an overhand knot at least 1" (2.5 cm) from the end of the rope to prevent slipping. • Thread the other end of the rope through the hole in the release arm of the outer trolley. • Adjust rope length so the handle is 6 feet (1.83 m) above the floor. Secure with an overhand knot. NOTE: If it is necessary to cut the rope, heat seal the cut end with a match or lighter to prevent unraveling. 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 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 obstructions. • NEVER use handle to pull door open or closed. If rope knot becomes untied, you could fall. Trolley Trolley Release Arm Emergency Release Handle NOTICE Overhand Knot 17
