INSTALLATION STEP 7
Install the Light and Lens
INSTALL THE LIGHT
• Install a 75 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.
• Use A19, standard neck garage door opener bulbs for
replacement.
NOTE: Use only standard light bulbs. The use of short
neck or specialty light bulbs may overheat the endpanel
or light socket.
INSTALL THE LENS
• Locate and loosen (approximately 1/8" (3 mm)) the two
screws near top of opener front panel.
• Position lens against panel with slotted tabs directly
below screws. Slide lens up to seat tabs behind
screws.
• Snap bottom tabs of lens into panel slots.
• Retighten top panel screws to secure lens.
INSTALLATION STEP 8
Attach the Emergency Release Rope
and Handle
• Thread one end of the rope through the hole in the top
of the red handle so “NOTICE” reads right side up as
shown. 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. Ensure that the rope and handle clear
the tops of all vehicles to avoid entanglement. 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.
