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.
INSTALLATION STEP 9
Attach the Emergency Release Rope
and Handle
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 the fl oor, 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.
INSTALLATION STEP 10
Electrical Requirements
To avoid installation diffi culties, do not run the opener
at this time.
To reduce the risk of electric shock, your garage door
opener has a grounding type plug with a third grounding
pin. This plug will only fi t into a grounding type outlet.
If the plug doesn’t fi t into the outlet you have, contact a
qualifi ed electrician to install the proper outlet.
If permanent wiring is required by your local code, refer
to the following procedure.
To make a permanent connection through the 7/8" hole in
the top of the motor unit:
1. Remove the motor unit cover screws and set the cover
aside.
2. Remove the attached 3-prong cord.
3. Connect the black (line) wire to the screw on the brass
terminal; the white (neutral) wire to the screw on
the silver terminal; and the ground wire to the green
ground screw. The opener must be grounded.
4. Reinstall the cover.
To avoid installation diffi culties, do not run the opener
at this time.
To prevent possible SERIOUS INJURY or DEATH from
electrocution or fi re:
• Disconnect ALL electric and battery power BEFORE
performing ANY service or maintenance.
• Garage door installation and wiring MUST be in
compliance with ALL local electrical and building
codes.
• NEVER use an extension cord, 2-wire adapter, or
change plug in ANY way to make it fi t outlet. Be sure
the opener is grounded.
