Planning
Survey your area to see if any of the conditions below
apply to your installation. Additional materials may be
required. You may find it helpful to refer back to this page
as you proceed with the installation of your operator.
Depending on your requirements, there are several
installation steps which may call for materials or hardware
not included in the carton.
This operator is compatible with:
• Doors that use a torsion bar, springs and a door no
more than 14' (4.2 m) high.
• 4"-6" (10 cm - 15 cm) drums, not to be used on tapered
drums over 6" (15 cm).
• High lift and standard lift sectional doors up to 14'
(4.2 m) high.
• Doors up to 18' (5.4 m) wide.
• Doors up to 180 sq. ft. (16.7 sq. m).
• 1" (2.5 cm) torsion bar only.
• Review or inspect proposed installation area. Operator
can be installed on left or right side of door. Select the
side that meets the requirements listed below.
- Must have minimum of 2-1/2" (6.4 cm) between the
wall and the center of the torsion bar.
- Must have minimum of 3" (7.6 cm) between the ceiling
and the center of torsion bar.
- Must have minimum of 8" (20.3 cm) between the side
wall (or obstruction) and the end of torsion bar.
• The torsion bar must extend at least 1" to 5"
(2.5 cm to 12 cm) past the bearing plate.
• An electric outlet is required within 6' (1.8 m) of the
installation area. If outlet does not exist, contact a
qualified electrician.
• Depending upon building construction, extension
brackets or wood blocks may be needed to install safety
reversing sensors.
• Alternate floor mounting of the safety reversing sensors
will require hardware not provided.
• A model 475LM EverCharge
TM
Standby Power Unit is
strongly recommended if there is no access door to the
garage, as this operator cannot be used in conjunction
with an external emergency release mechanism.
• Any gap between the floor and the bottom of the door
must not exceed 1/4" (6 mm). Otherwise the safety
reversal system may not work properly.
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 this type of
movement is not corrected, life of this operator will be
greatly reduced.

Before you begin:
• Disable locks.
• Remove any ropes connected to door.
• Complete the following test to make sure your door is
balanced and is not sticking or binding:
1. Lift the door about halfway as shown. Release the
door. If balanced, it should stay in place, supported
entirely by its springs.
2. Raise and lower the door to see if there is any
binding or sticking.
If your door binds, sticks or is out of balance, call a
trained door systems technician.
3. Verify equal cable tension on each side of door.
Cable tension should remain equal during the entire
travel of the door.
To prevent possible SERIOUS INJURY or DEATH:
• ALWAYS call a trained door systems technician if door binds,
sticks or is out of balance. An unbalanced door may not
reverse when required.
• NEVER try to loosen, move or adjust door, door springs,
cables, pulleys, brackets or their hardware, ALL of which are
under EXTREME tension.
• Disable ALL locks and remove ALL ropes connected to door
BEFORE installing and operating door operator to avoid
entanglement.
To prevent damage to door and operator:
• ALWAYS disable locks BEFORE installing and operating the
operator.
• ONLY operate door operator at 120V, 60 Hz to avoid
malfunction and damage.
• DO NOT exceed 10 complete cycles of door operation per
hour.

Electrical Requirements
To avoid installation difficulties, do not run the
operator at this time.
To reduce the risk of electric shock, your operator has a
grounding type plug with a third grounding pin. This plug
will only fit into a grounding type outlet. If the plug doesn’t
fit into the outlet you have, contact a qualified 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 back of the operator (according to local code):
• Remove the operator from the torsion bar, remove cover
screws and set the cover aside.
• Remove the attached green ground terminal.
• Cut black and white wires and strip away 1/2" (1.3 cm)
of insulation, 3" (7.6 cm) before spade terminals.
• Remove the power cord from unit.
• Install a 90o conduit or flex cable adapter to the 7/8"
hole. Reinstall operator to torsion bar.
• Run wires through conduit, cut to proper length and
strip insulation.
• Attach with wire nuts provided.
• Properly secure wire under plastic ties so that wire does
not come in contact with moving parts.
• Reinstall the cover.
To avoid installation difficulties, do not run the
operator at this time.
To prevent possible SERIOUS INJURY or DEATH from
electrocution or fire:
• Be sure power is not connected to the operator, and
disconnect power to circuit BEFORE removing cover to
establish permanent wiring connection.
• 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 fit outlet. Be sure the operator is
grounded.

INSTALLATION STEP 9
Install The Protector System
The safety reversing sensor
aligned correctly before the door operator will move in
the down direction. This is a required safety device
and cannot be disabled.
IMPORTANT INFORMATION ABOUT THE SAFETY REVERSING SENSOR
When properly connected and aligned, the safety
reversing sensor will detect an obstacle in the path of its
electronic beam. The sending eye (with an amber indicator
light) transmits an invisible light beam to the receiving eye
(with a green indicator light). If an obstruction breaks the
light beam while the door is closing, the door will stop and
reverse to full open position, and the operator lights will
flash 10 times.
The units must be installed inside the building so that the
sending and receiving eyes face each other across the
door, no more than 6" (15 cm) above the floor. Either can
be installed on the left or right of the door as long as the
sun never shines directly into the receiving eye lens.
The mounting brackets are designed to clip onto the track
of sectional doors without additional hardware.
must
®
be connected and
Be sure power is not connected to the door operator BEFORE
installing the safety reversing sensor.
To prevent SERIOUS INJURY or DEATH from a closing door:
• Correctly connect and align the safety reversing sensor. This
required safety device MUST NOT be disabled.
• Install the safety reversing sensor so beam is NO HIGHER
than 6" (15 cm) above floor.
If it is necessary to mount the units on the wall, the
brackets must be securely fastened to a solid surface such
as the wall framing. Extension brackets (see accessories)
are available if needed. If installing in masonry
construction, add a piece of wood at each location to
avoid drilling extra holes in masonry if repositioning is
necessary.
The invisible light beam path must be unobstructed. No
part of the door (door tracks, springs, hinges, rollers or
other hardware) may interrupt the beam while the door is
closing.

Be sure power to the operator is disconnected. Install
and align the brackets so the safety reversing sensors will
face each other across the door, with the beam no higher
than 6" (15 cm) above the floor. They may be installed in
one of three ways, as follows.
Door track installation (preferred) (Figure 1):
• Slip the curved arms over the rounded edge of each door
track, with the curved arms facing the door. Snap into
place against the side of the track. It should lie flush, with
the lip hugging the back edge of the track, as shown in
Figure 1.
If your door track will not support the bracket securely,
wall installation is recommended.
Wall installation (Figure 2 and 3):
• Place the bracket against the wall with curved arms
facing the door. Be sure there is enough clearance for
the sensor beam to be unobstructed.
• If additional depth is needed, an extension bracket
(See Accessories) or wood blocks can be used.
• Use bracket mounting holes as a template to locate and
drill (2) 3/16" diameter pilot holes on the wall at each
side of the door, no higher than 6" (15 cm) above
the floor.
• Attach brackets to wall with lag screws (Not provided).
• If using extension brackets or wood blocks, adjust right
and left assemblies to the same distance out from the
mounting surface. Make sure all door hardware
obstructions are cleared.
Floor installation (Figure 4):
• Use wood blocks or extension brackets (See
Accessories) to elevate sensor brackets so the lenses
will be no higher than 6" (15 cm) above the floor.
• Carefully measure and place right and left assemblies at
the same distance out from the wall. Be sure all door
hardware obstructions are cleared.
• Fasten to the floor with concrete anchors as shown.

MOUNTING AND WIRING THE SAFETY REVERSING SENSORS
• Slide a 1/4"-20x1/2" carriage bolt head into the slot on
each sensor. Use wing nuts to fasten safety reversing
sensors to brackets, with lenses pointing toward each
other across the door. Be sure the lens is not obstructed
by a bracket extension (Figure 5).
• Finger tighten the wing nuts.
• Run the wires from both safety reversing sensors to the
operator. Use insulated staples to secure wire to wall
and ceiling.
• Strip 7/16" (11 mm) of insulation from each set of wires.
Separate white and white/black wires sufficiently to
connect to the operator quick-connect terminals: white to
white and white/black to grey (Figure 6).
ALIGNING THE SAFETY REVERSING SENSORS
• Plug in the operator. The indicator lights in both the
sending and receiving eyes will glow steadily if wiring
connections and alignment are correct.
The sending eye amber indicator light will glow regardless
of alignment or obstruction. If the green indicator light in
the receiving eye is off, dim, or flickering (and the invisible
light beam path is not obstructed), alignment is required.
• Loosen the sending eye wing nut and readjust, aiming
directly at the receiving eye. Lock in place.
• Loosen the receiving eye wing nut and adjust the safety
reversing sensor until it receives the sender’s beam.
When the green indicator light glows steadily, tighten the
wing nut.
Figure 5
TROUBLESHOOTING THE SAFETY REVERSING SENSORS
1. If the sending eye indicator light does not glow steadily
after installation, check for:
• Electric power to the operator.
• A short in the white or white/black wires. These can
occur at staples, or at operator connections.
• Incorrect wiring between safety reversing sensors and
operator.
• A broken wire.
2. If the sending eye indicator light glows steadily but the
receiving eye indicator light doesn’t:
• Check alignment.
• Check for an open wire to the receiving eye.
3. If the receiving eye indicator light is dim, realign
either sensor.
NOTE:
When the invisible beam path is obstructed or
misaligned while the door is closing, the door will reverse.
If the door is already open, it will not close.

HAVING A PROBLEM? (TROUBLESHOOTING)
1. The operator doesn’t operate from either the Door
Control or the remote control:
• Does the operator have electric power? Plug a lamp
into the outlet. If it doesn’t light, check the fuse box
or the circuit breaker. (Some outlets are controlled by
a wall switch.)
• Is there a build-up of ice or snow under the door?
The door may be frozen to the ground. Remove any
restriction.
• The door spring may be broken. Have it replaced
(see page 3 for reference).
2. Operator operates from the remote, but not from
the Single Button Control Station:
• Are the wiring connections correct? Review
Installation Step 5.
3. The door operates from the Single Button Control
Station, but not from the remote control:
• Program the operator to match the remote control
code. (Refer to instructions on the motor unit panel.)
Repeat with all Remotes.
4. The remote control has short range:
• Check to be sure the antenna on the side or back
panel of operator extends fully downward.
• Some installations may have shorter range due to a
metal door, foil backed insulation, or metal siding.
5. The door opens and closes by itself:
• Be sure that all remote control push buttons are off.
• Remove the bell wire from the door control terminals
and operate from the remote only. If this solves the
problem, the single button control station is faulty
(replace), or there is an intermittent short on the wire
between the control console and the motor unit.
• Clear memory and re-program all remote controls.
6. The door doesn’t open completely:
• Is something obstructing the door? Is it out of
balance, or are the springs broken? Remove the
obstruction or repair the door.
7. The door opens but won't close:
• Check cable tension monitor (see installation step 4).
• Check the safety reversing sensor. See Installation
Step 9.
• See Adjustment Step 2. For an existing installation,
see below.
Repeat the safety reverse test after the adjustment
is complete.
8. The door reverses for no apparent reason:
• Check cable tension monitor (see installation step 4).
• Is something obstructing the door? Pull the
emergency release handle. Operate the door
manually. If it is unbalanced or binding, call a trained
door systems technician.
• Clear any ice or snow from the floor area where the
door closes.
• Review Adjustment Step 2.
Repeat safety reverse test after adjustments.
9. The door reverses for no apparent reason:
• Check the safety reversing sensor. Remove any
obstruction or align the receiving eye. See Installation
Step 9.
10. The operator strains to operate door:
• The door may be out of balance or the springs may
be broken. Close the door and use the emergency
release handle to disconnect the door. Open and
close the door manually. A properly balanced door
will stay in any point of travel while being supported
entirely by its springs. If it does not, disconnect the
operator and call a trained door systems technician.
11. The operator motor hums briefly, then won’t work:
• The door springs may be broken. See above.
23
Page 24
Having a Problem? (Continued)
12. The operator won't operate due to power failure:
• Use the emergency release handle to disconnect the
door. The door can be opened and closed manually.
When power is restored, pull manual release a
second time.
• If a Standby Power Unit is connected, the operator
should be able to operate up to 20 times without
power.
13. Door loses limits.
• Collar not tightened securely. Tighten collar
(see Assembly Steps 1 and 2) and reprogram limits
(see Adjustment Step 1).
14. The operator moves when the door is in operation:
• Some minor movement is normal for this product. If it
is excessive the collar will wear prematurely.
• Check to make sure the torsion bar is not moving
left/right excessively.
• Check to make sure the torsion bar is not visibly
moving up and down as it rotates.
• Check that the operator is mounted at a right angle
to the jackshaft. If not, move the position of the
mounting bracket.
