IMPORTANT INSTALLATION INSTRUCTIONS
WARNING – To reduce the risk of death or serious injury to
persons:
1. READ AND FOLLOW ALL INSTALLATION INSTRUCTIONS.
2. Install only on a properly operating and balanced door. A door that is operating improperly could
cause severe injury. Have qualified service personnel make repairs to cables, spring assemblies,
and other hardware before installing the operator.
3. Remove all pull ropes and remove, or make inoperative, all locks (unless mechanically and/or
electrically interlocked to the power unit) that are connected to the door before installing the
operator.
4. 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.
5. Do not connect the door operator to the source of power until instructed to do so.
6. Locate the control station: (a) within sight of the door, and (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.
7. Install the Entrapment Warning Placard next to the control station in a prominent location.
8. 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.
9. Read and understand the wiring diagram of the operator and the control station (open-close-stop
push button), and any other equipment to be connected to the operator.
10. To avoid damage to the door and operator, make all door locks inoperative. Secure locks in the
unlocked position, or install external electrical interlocks to prevent operation with the locks
engaged.
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. If the operator is provided with an auxiliary chain operator, the hand chain must be kept inside the
chain bag when operating electrically.
15. For products having a manual release, instruct the end user on the operation of the manual release.

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. Bolt the operator mounting plate to the
door bracket plate.
4. Attach and tighten the three mounting legs
to the mounting plate. (Not applicable for
1hp, 1½hp, 2hp)
5. Mount the operator to the three legs and
tighten (for 1/2 and 3/4hp only). For other
horsepowers, mount the operator to the
mounting plate.
(Figure 1 - for 1/2hp and 3/4hp)
(Figure 2 - for 1hp and 1½hp)
6. 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.
(See Figure 3 for 1/2hp and 3/4hp; see Figure 4 for
1hp and 1½hp)
7. 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 1- S1 location for 1/2hp and
3/4hp), (See figure 2 - T1, T2 for 1hp and
1½hp).
2. Once the drive chain has been tightened and
the base leg screws have been set, then
tighten the operator set screws.

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 circuit 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.
 To avoid damage to door and operator, make all door locks inoperative. Secure lock(s)
in the unlocked position, or install electrical interlocks to prevent operation with the
lock engaged.

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.
