Survey your garage area to see if any of the conditions below apply to your installation.
Depending on your requirements, additional materials may be required.
THIS GARAGE DOOR OPENER IS COMPATIBLE WITH:
• Doors that use a torsion bar and springs. The torsion bar must be 1 inch (2.5 cm)
diameter.
• 4-6 inch (10-15 cm) drums, not to be used on tapered drums over 6 inches (15 cm).
• High lift and standard lift sectional doors up to 14 feet (4.2 m) high.
• Doors up to 18 feet (5.4 m) wide.
• Doors up to 180 sq. ft. (16.7 sq. m).
Review or inspect proposed installation area. The garage door opener can be installed on
the left or right side of door. Select the side that meets the requirements listed below.
Must have minimum of 2-1/2 inches
(6.4 cm) between the garage wall and
the center of the torsion bar.
Must have minimum of 3 inches
(7.6 cm) between the ceiling and the
center of torsion bar.
Must have minimum of 8 inches
(20.3 cm) between the side garage
wall (or obstruction) and the end of
torsion bar.
The torsion bar must extend at least
1-5 inches (2.5-12 cm) past the
bearing plate.
An electric outlet is required within
6 feet (1.8 m) of the installation area.
If outlet does not exist, contact a
qualifi ed electrician.
Depending upon garage construction,
extension brackets or wood blocks
may be needed to install safety
reversing sensors.
Alternate fl oor mounting of the
safety reversing sensors will require
hardware not provided.
Any gap between the fl oor and the
bottom of the door must not exceed
1/4 inch (6 mm), otherwise the
safety reversal system may not work
properly.
A model 475LMC EverCharge
®
Standby Power System is strongly
recommended if there is no access
door to the garage, as this garage door
opener cannot be used in conjunction
with an external emergency release
mechanism.

Introduction
NOTE:
Inspect the torsion bar while the
door is raised and lowered. It is important
that there is no noticeable movement up
and down or left and right. If the movement
is not corrected, the life of the garage door
opener will be greatly reduced.
