IMPORTANT INSTALLATION INSTRUCTIONS
WARNING – To reduce the risk of death or serious injury to
persons:
1. READ AND FOLLOW ALL INSTALLATION INSTRUCTIONS.
WARNING! – Components under extreme spring tension can cause death or serious injury.
2. Install only on a properly operating and balanced door. A door that is operating improperly could
cause death or serious injury. Trained door systems technicians make all necessary adjustments
and repairs to the door before installing the operator.
Note: Fire door spring tension must be adjusted per the manufacturer’s installation instructions to
allow for automatic closing during a drop test, fusible link/alarm activation and/or power failure
(Power failure condition only applies to operators capable of fail-safe closing).
3. Remove all pull ropes.
4. Unless the door operator includes an internal lock sensing system, or external electrical interlocks
are installed, remove or make all door locks inoperative, or secure locks in the unlocked position to
prevent operation with the locks engaged.
5. Install the door operator at least 8 feet or more above the floor if the operator has exposed moving
parts. If the operator must be mounted less 8 ft (2.44 m) above the floor, then exposed moving parts
must be protected by covers or guarding. Contact the manufacturer.
6. Do not connect the door operator to the source of power until instructed to do so.
7. Locate the control station (open-close-stop push button, key station, or the like): (a) within sight of
the door, (b) at a minimum height of 5 feet above floors, landings, steps, or any other adjacent
walking surface and (c) away from all moving parts of the door.
8. Install the Entrapment Warning Placard next to the control station in a prominent location.
9. Make sure the available power supply to be connected to the operator is of the same voltage,
frequency, phase and wattage as indicated on the nameplate of the operator.
10. Read and understand the wiring diagram of the operator and the control station and any other
equipment to be connected to the operator.
11. Always disconnect power whenever installing or servicing the door operator or door.
12. All wiring must be permanent and comply with National Electrical Code (NEC) and local code
requirements.
13. Any change in mounting position may result in a change of operator rotation and consequently in a
change of control functions. Consult factory for any changes.
14. For products having a manual release, instruct the end user on the operation of the manual release.

Sensing Edge*: (Optional) Sensing device attached to the bottom edge of the door.
Non-Contact Device*: (Optional) Photo eye device.
* Per the requirements of UL Standard 325, the door operator is setup for constant pressure
to close the door. As an alternative, the door may be provided with a monitored entrapment
protection device that will reverse the door upon contact with or detection of an obstruction
during closing. Adding an entrapment device would enable momentary close operation.
Notes:
1. Non-contact device (photo eye) can be used on doors up to 45 ft. wide (or maximum rated range of
device if less than 45 ft.). Use a sensing edge to provide entrapment protection on doors over 45 ft.
wide.
2. Sensing edge can be used on all doors.

OPERATOR MOUNTING
1. Before the operator is installed, verify that
the door is properly operating and balanced.
2. Make sure the layout of the mounting holes
on the bracket is correct.
3. Mount the operator base to the mounting
plate.
4. When the operator assembly is attached to
the door bracket, be sure the door driven
sprocket is properly aligned with the
operator drive sprocket before securing the
driven sprocket to the shaft.
5. The shelf or bracket must provide adequate
support for the operator. Prevent play
between the operator and the door
shaft. The operator must be securely
attached with the drive shaft parallel to the
door shaft. It may be necessary to field
brace the operator/bracket.

DRIVE CHAIN ADJUSTMENT
NOTE: Use correct type, size and proper
length of roller chain.
1. Adjust the drive chain by tilting or move the
operator so that there is about 1/4” of slack
when the chain is depressed.
Note: The set screw included in the operator
may be used for adjustment.
(See figure - T1, T2 location)

WIRING INSTRUCTIONS
WARNING
Disconnect power at the fuse box before proceeding with any wiring.
1. Do not install any wiring or attempt to run this operator without checking the wiring diagram located
on the inside of the control box cover.
2. Do not turn on power until you have finished making all power and control wiring connections.
3. Do not run power and control wiring in the same conduit.
4. Any wire connected to the control panel must be protected by conduit or other means to ensure the
safety and permanency of the wiring.
5. Use copper wire inside the control panel.
6. A separate fuse line of adequate capacity is needed for the operator.
7. The operator must be properly grounded. The ground screw, painted green, is located inside the
control panel.
8. For an operator, system, or external device requiring field installed wiring between a Class 2 output
of an operator and an external device, the type of wiring shall be R/C (AVLV2/8), AWM, min. 22
AWG, rated 60°C, with VW-1/FT2.
WARNING
 Failure to properly ground the operator could result in electric shock and serious injury
or death.
 Unless the operator includes an internal lock sensing system, or external electrical
interlocks are installed, remove or make all door locks inoperative, or secure locks in
the unlocked position. Failure to disable the locks could result in damage to the door or
operator.

CONTROL WIRING
WARNING
Disconnect power at the fuse box before proceeding with any wiring.
1. Locate the control station where the user can
clearly see the operation of the door. Mount the
enclosed placard adjacent or near the door.
WARNING
Controls shall be located far enough away from the door, or positioned such that the user is
prevented from coming in contact with the door, while operating the controls.
2. Do not run control wiring in the same conduit as power wiring.
3. Any wire connected to the control panel must be protected by conduit or other means to ensure the
safety and permanency of the wiring.
WARNING
 Do not use radio controls with your operator unless some type of entrapment
protection device has been installed. Failure to do so may result in serious injury or
death to person(s) trapped beneath the door.
 Changing from left hand to right hand or vice versa could result in change of control
wiring. Consult factory for details.

ENTRAPMENT DEVICES WIRING
WARNING
If the door is not visible from the control station, or if any device other than the control
station is used to activate the door, an entrapment protection device must be installed on
the door. Failure to install an entrapment protection device may result in serious injury or
death to person(s) trapped beneath the door.
1. Complete limit switch adjustments before
making any sensing edge/non-contact
device wiring connections to the operator.

LIMIT SWITCH ADJUSTMENT
Make sure the limit cams are positioned between the limit switch actuators before proceeding
with adjustments.
1. Open / Remove the control panel cover.
2. Open or close door to determine the moving direction of the limit switch cams.
3. Open or close door to the desired position.
WARNING
Disconnect power before adjusting limit switch cams.
4. While pressing the spring-loaded lever (G), which holds the limit switch cams in place, adjust the limit
switch cam (E or F) until the micro switch (C or D) clicking sound is heard.
5. If the limit switch cam cannot be rotated to its desired position, release the lever and move the door
away from the desired position, then adjust the limit switch cam to its desired position. It may be
necessary to repeat this step until the exact position has been reached.
6. Repeat step 3 and 4 for the opposite position. Adjust close limit cams so that actuator is engaged as
door fully seats at the floor.
7. Micro switch (A or B) can be adjusted to accommodate sensing edge cut-off position.
