INSTALLATION STEP 7
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.
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.
