INSTALLATION INSTRUCTIONS
For Sectional Type Doors
IMPORTANT SAFETY NOTES
Please read the instructions carefully! This garage door
operator is designed to provide safe and reliable service
if installed and tested as described in these instructions.
A garage door is the largest mechanical appliance in a
residence. Care must be taken to prevent injury or death
during installation and operation of the garage door and
garage door operator.
1 Check the Door Balance
1 From outside the garage, slowly open the door all the
way, and then close it all the way. Notice if there is
any binding, sticking or rubbing. The door should move
smoothly in both directions.
2 Raise the garage door about halfway up. Carefully
release the door and see if the door balances. It should
stay in place. Close the door.
IMPORTANT: If the garage door is unbalanced or
the door travel isn’t smooth, have a qualified garage
door professional adjust or repair the door.
2 Attach the Rail to the Operator
1 Place the operator head on the garage floor with
cardboard underneath it to protect the finish.
2 Align the rail over the center of the operator head.
3 Be sure the flat on the sprocket lines up with the flat on
the drive shaft.
4 Slide the sprocket onto the shaft.
5 Attach the rail to the operator head by installing four
¼-20 x ¾” bolts.
6 Tighten the four bolts in the order shown with a 7/16”
socket.
3 Locate the Header Bracket Position
1 Close the door.
2 From inside the garage, use a pencil to mark the
vertical centerline of the door on the header wall and
on the top panel of the door.
3 Examine the area above the center of the door on the
door header wall for a header bracket mounting location.
4 Open the door to the high-rise point (the point where
the top edge of the door is highest above the floor) and
measure the distance to the floor.
5 Close the door and use a pencil to mark the header
wall 1” above the measured high-rise point.
NOTE: In some installations, the header bracket
location will be higher than the door header. This will
require adding a 2x4 (or larger) cross piece to the wall
studs to provide a mounting location for the header
bracket. Use lag screws (not supplied) to attach the
2x4 to the studs.
6 On doors with low headroom, the header bracket can
be attached to the ceiling up to 6” back from the header
wall (see next step).
4 Install the Header Bracket
Attaching the Header Bracket to the Wall
1 Hold the header bracket on the center line drawn
above the door with the bottom edge of the bracket on
the line marked above the high-rise point.
2 Use a pencil to mark the two bracket holes.
3 Drill two 3/16” pilot holes about 2” deep.
4 Use a ½” socket to fasten the bracket with two 5/16” x 2”
lag screws.
Attaching the Header Bracket to the Ceiling
NOTE: On a finished ceiling, be sure there is a joist
to fasten to under the sheetrock where the header
bracket will be located (use a stud finder). If there is
none, install a 2x4 cross piece between the two closest
joists to fasten the header bracket onto.
1 Extend the center line drawn on the header wall along
the ceiling.
2 Hold the bracket on the center line with the edge of the
bracket no further than 6” from the header wall.
3 Use a pencil to mark the two bracket holes.
4 Drill two 3/16” pilot holes about 2” deep.
5 Use a ½” socket to fasten the bracket with two
5/16” x 2” lag screws.
5 Connect the Rail to the Header Bracket
1 Place assembled operator on the empty carton on the
floor with rail towards the door.
2 Insert the end of the rail into header bracket.
3 Insert the 5/16” x 2-3/8” clevis pin through header
bracket and rail.
4 Secure the clevis pin with the hitch pin.
6 Hang the Operator
Installation requirements vary with garage construction.
Hanging brackets should be angled to provide rigid
support. Hanging material is not provided. Angle iron
and lag screws are recommended. DO NOT USE NAILS.
Following are typical operator hanging methods. Certain
installations will require improvised methods.
1 Raise the operator head and set it on top of a stepladder
(use extra spacers on top of ladder if it isn’t tall enough).
2 Carefully open the door to the full up position. Lay a 2x4
across the top section of the door as a spacer. Adjust
the operator height until the rail touches the spacer. The
rail should be close to level.
3 Center the operator head and rail with the centerline
mark on the top of the door.
4 For finished ceilings only: An angle iron cross piece
between the two closest joists above the operator will be
required. Mark mounting hole locations, drill pilot holes
and attach the piece with two lag screws (not supplied).
5 Measure the distance from each of the operator’s
hanging tabs to the ceiling joists or angle iron cross piece.
6 Cut two angle iron pieces to the required lengths for
hanging brackets. Bend brackets if required.
For unfinished ceilings: Hold each bracket in place
and use a pencil to mark the locations where they will
be attached to the joists, drill pilot holes and attach the
pieces with two lag screws (not supplied).
For finished ceilings with an angle iron cross piece:
Attach the two hanging brackets to the cross piece
with two bolts and two keps nuts (not supplied).
7 Attach operator to hanging brackets using two 5/16-18 x
1” hex bolts and two 5/16-18 keps nuts (supplied). Insert
bolts from the inside of hanger brackets with the nuts on
the outside of the operator. Tighten nuts with a ½” socket.
8 Tighten all hanging hardware.
9 Open and close the door manually. The door should
clear the rail by at least 1”.
10 Attach the trolley’s release lever to the red release
handle with the cord supplied so the handle is at least
6 feet from the floor. Cut off any excess cord.
11 Remove the light cover to access the lamp socket.
Install a 100 watt maximum rough service in the lamp
socket. Reattach the light cover.
IMPORTANT INSTALLATION SAFETY INSTRUCTIONS
WARNING
TO REDUCE THE RISK OF SEVERE INJURY OR DEATH TO PERSONS, REVIEW
THESE INSTALLATION SAFETY STEPS BEFORE PROCEEDING
1 READ AND FOLLOW ALL INSTALLATION INSTRUCTIONS.
2 Install only on a properly balanced garage door. An improperly balanced door could result in severe
injury or death. Repairs to cables, spring assemblies, and other hardware must be made by a qualified
service person before installing the operator.
3 Use this operator only with sectional overhead doors no more than 10 ft. tall.
4 Disable all locks and remove all ropes connected to the garage door before installing the operator.
Ropes connected to a garage door can cause entanglement and death.
5 If possible, install door operator 7 feet or more above the floor with the manual release handle
mounted 6 feet above the floor.
6 Do not connect the operator to the power source until instructed to do so.
7 Locate the wall station within sight of the door at a minimum height of 5 feet so that small children
cannot reach it. Locate the wall station away from all moving parts of the door.
8 Install the User Safety Label on the wall adjacent to the wall station.
9 Upon completion of the installation, the door must reverse when it comes in contact with a 1-1/2” high
object (or a 2x4 laid flat at the center of the door) on the floor and when the infrared safety beam is blocked.
10 Do not wear watches, rings or loose clothing while installing or servicing an operator. Jewelry or
loose clothing can be caught in the mechanism of the garage door or the operator.
11 DISCONNECT THE ELECTRIC POWER FROM THE GARAGE DOOR OPERATOR BEFORE MAKING ANY
REPAIRS OR REMOVING THE COVER.
7 Install the Wall Station
NOTE: 22 AWG 2-conductor wall station and safety
beam wire is supplied with the operator, Use this wire
or the installation’s pre-wiring. For additional wire,
contact Linear for information regarding the 24-pack
Model HAE00009 wire and wire clip kit.
UL NOTE: All low voltage Class 2 cable used with this
operator must be UL Listed Type CL2, CL2P, CL2R, or
CL2X or other cable with equivalent or better electrical,
mechanical, and flammability ratings.
1 Strip back ½” of insulation and connect a wire to each
of the two terminals on the back of the wall station.
2 Use the screws provided to mount the wall station near
an access door at a minimum height of five feet. SEE
IMPORTANT WARNING ABOVE!
3 For non-prewired installations, route the wire to
the back of the operator. Use insulated staples (not
supplied) to secure the wire. Staples must straddle
both wires to avoid electrical shorts.
4 Cut the wall station wire about 6” longer than needed to
reach the operator terminals. Strip back ½” of insulation.
5 Connect either wire to the operator’s PUSHBUTTON
terminal and the other wire to the operator’s COMMON
terminal.
6 Apply the User Safety Instruction Label to the wall next
to the wall station. Use staples or tacks to help the
label remain in place over time.
IMPORTANT! DO NOT PLUG THE OPERATOR IN AT
THIS TIME! More installation is required.
8 Install the Safety Beam
NOTE: The safety beam’s infrared light beam must
not be obstructed by the door, or by any part of the
door hardware. Use wooden spacers between the
beam brackets and wall if necessary to create proper
clearance.
1 Assemble the two safety beam brackets from the four
L-shaped brackets using two ¼-20 x ¾” bolts and ¼-20
keps nuts (one nut & bolt for each bracket).
2 Position the assembled brackets on each side of the
door so the center line of the safety beam lenses
will be 5-1/2” above the floor. Use the index marks
on the brackets to make the bracket assemblies equal
lengths. Mark the locations for the bracket mounting
screws.
NOTE: The safety beam receiver (the unit with two
indicators) should be located on the “shady” side of
the door to prevent sunlight from shining directly into
the receiver’s lens.
3 Drill two 3/16” pilot holes for lag screws at marks.
Mount the brackets with two ¼” x 1-¼” lag screws and
tighten with a 7/16” socket.
4 Insert the sender and receiver into the bracket holes
so the lenses of the units will face each other. Twist the
units until the spring clips lock into a detent mark on
the brackets. To protect the units from being bumped
after installation, it is recommended to mount the
sender and receiver inside the brackets as shown.
IMPORTANT: Be careful to route the safety beam wiring
away from any moving parts of the door or operator.
5 For non-prewired installations, route the wires from
the sender and receiver, up the wall above the door
hardware, then over to the center of the door, then along
the top of the rail (or ceiling), and back to the operator
head. Cut the wires about 6” longer than needed to
reach the operator terminals. Strip back ½” of insulation
from the ends of the wires.
6 For non-prewired installations, secure all the wires
to the wall and ceiling with insulated staples (not
supplied). Staples must straddle both wires to prevent
shorts. Secure the wire to the top of the rail with wire
clips (supplied).
7 At the operator, twist one wire from each pair together,
then twist the other wire from each pair together.
8 Attach either twisted connection to the operator’s
BEAM terminal. Connect the other twisted connection
to the operator’s COMMON terminal.
9 Install the Door Bracket and Door Arm
1 Fully close the door. Hold the door bracket against the
inside of the door’s top panel. Align the top edge of the
bracket 2” to 4” below the top edge of the door; or, if
there is a structural support across the top of the door,
place the top edge of the bracket directly below the
support. Align the vertical centerline drawn on the door
with the center of the bracket. See the figure for details.
Mark the left and right holes of the bracket.
2 Drill ¼” holes at marks and insert two ¼-20 x 2” carriage
bolts (not supplied) from outside of door through the
door bracket.
3 Secure door bracket with two ¼-20 keps nuts (not
supplied). Tighten with a 7/16” socket.
4 Slide the 5/16” x 1-3/8” clevis pin through one hole on
door bracket; then the single hole on the curved door arm;
then through the other hole on the door bracket. Secure
the clevis pin with the hitch pin.
5 Insert the single hole end of the straight door arm into
the slot in the trolley. Slide the 1-1/8” clevis pin through
the hole and secure it with a hitch pin.
6 Flip the trolley release lever to disconnect the trolley.
7 Rotate the curved door arm upward to meet the
straight door arm connected to the trolley. Align the
two door arms so that the holes in both arms overlap.
NOTE: The straight door arm should be slightly angled
toward the operator head.
CONNECTING DOOR ARMS
1 Line up door arms until trolley is positioned as shown.
Connect the arms together using two 5/16-18 x 1” bolts
inserted in the highest and lowest matching holes,
secure the bolts with two 5/16” keps nuts, tighten with
a ½” socket.
10 Connect the Operator to Power Source
Cord and Outlet Connection
The operator should be connected to a grounded
receptacle on the ceiling or near the operator head. If
none is available which will accept the grounded operator
plug, one should be installed by a qualified electrician. Do
not use an extension cord.
1 Plug the operator into a grounded receptacle.
2 When the operator is plugged in, a click should sound
in the operator and the light should turn on. If light does
not turn on, check the power source and light bulb.
Permanent Wiring
SOME LOCAL ELECTRICAL CODES REQUIRE
PERMANENT WIRING BETWEEN THE OPERATOR
AND THE POWER SOURCE THROUGH A CONDUIT.
IT IS RECOMMENDED THAT YOU HAVE A LICENSED
