INSTALLATION STEP 7

Install the Light 

• 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 up to a 100 watt maximum light bulb in each

socket. The light will turn O

N

 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.

• If the bulbs burn out prematurely due to vibration,

replace with a Garage Door Opener bulb.

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 “

N

OTICE” 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.

8

3 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.
