Read and Follow These Important Safety Instructions
You will see Warning and Caution statements on the following Pages.
Read and follow these safety instructions carefully. Failure to do so could result in serious personal injury or death.
Warning means that severe injury or death may result from failure to follow instructions
Caution means that property damage or injury may result from failure to follow instructions
• Be sure to read and follow all instructions carefully.
• To reduce the risk of electric shock, this equipment has a grounding type plug, that has a third (grounding) pin.
This plug will only fit into a grounding type outlet. If the Plug does not fit into the outlet, contact a qualified
electrician to install the proper outlet. Do not change the plug in any way.
• Check to make sure the garage door is properly installed and balanced. Garage door & parts are under
extreme tension and under no circumstance should you attempt to adjust on your own. Have a qualified
garage door service person make repairs to cables, spring and other hardware before installing the opener.
• Install Entrapment Warning Label next to control button. Read the Control Adjustment Warning Label. Install
Emergency Release Tag to the Emergency Release Cord. Mount the Emergency Release Knob 180cm from the
floor. Use the manual release only to disengage the trolley. Do not use the Red Release Cord and Knob to pull
door up or down. If possible, use the Emergency Release only when the door is closed.
• Do not connect opener to power source until instructed. Install door opener 210cm or more above floor.
• After installing opener, the door must reverse when it comes in contact with a 5cm high object. Check this safety
feature often.
• REMOVE ALL ROPES CONNECTED TO THE GARAGE DOOR.
• DISENGAGE ALL EXISTING GARAGE DOOR LOCKS TO AVOID DAMAGE TO THE GARAGE DOOR.
• Fiberglass, aluminum and steel doors must be reinforced to prevent damage. Consult with manufacturer for
recommendations.
• All installation and wiring must be done in strict compliance with local and state building and electrical codes.
Connect the power cord to a properly grounded outlet only. Do not in any way alter or remove the grounding pin.
Photo Eye System must be installed properly. Operators recommend Photo Eye System is installed on every
garage door for your added protection. Opening doors must not close and Closing doors must open once the
beam is broken. See the test procedure page 16.
• Locate push button within sight of garage door, away from all moving parts and out of reach of children (minimum
150cm above floor). To reduce the risk of injury to persons, use this operator only with a sectional door.
• Never operate the opener if the system is not operating properly.
• Always disconnect electric power before making repairs or removing cover.
• Activate opener only when the door is in full view and free from obstructions.
• No one should enter or leave the garage while the door is moving. Do not allow children to play near, or operate
the door. Keep the remote control away from children.
• After Installation is complete fasten this manual near the garage door. Perform periodic safety checks and
recommended maintenance and adjustments.
• NEVER GO UNDER A STOPPED, PARTIALLY OPEN DOOR.
• Test door opener monthly. The garage door MUST reverse on contact with a 5cm high object (or a two by 4 board
laid flat) on the floor. After adjusting either the force or the limit of travel, retest the door opener. Failure to adjust
the opener properly increases the risk of severe injury or death.
• For products having an emergency release, when possible, use the emergency release only when the door is
closed. Use caution when using this release with the door open. Weak or broken springs are capable of
increasing the rate of door closure and increasing the risk of severe injury or death.
• KEEP GARAGE DOORS PROPERLY BALANCED. See owner’s manual. An improperly balanced door increases
the risk of severe injury or death. Have a qualified service person make repairs to cables, spring assemblies, and
other hardware.
• SAVE THESE INSTRUCTIONS.

Product Features
1. Motor: Permanent Magnet Direct Current 24V DC Brush Motor.
2. Opener Lights: Turn on and off automatically with 4.5 minutes illumination for your safety and convenience.
3. Sensing System: A built-in sensing system detects obstructions during door operation. If in the Downward (close)
travel mode, the Opener will sense an obstruction and reverse to the full open position. In the Open mode, the
Opener will stop. In both cases the operator will beep continuously for 20 seconds. Since all doors are different, the
Sensing System has independent adjustments for customizing the level of force for the normal opening and closing of
specific door.
4. Close Limit positioning: In winter months it’s common for small pieces of ice or packed snow to be trapped under the
door. Ground swelling may also effect the close limit setting of the Opener. The Close Limit Switch overrides the
Sensing System under the last 5cm of closing travel and prevents the door from reversing if it encounters an
obstruction at this point. In case, it’s about time to shovel the snow or re-adjust the close limit higher.
5. Emergency Release: A pull cord allows manual disconnect and operation of door during power failure. Unit will
automatically reconnect when release is reset (the trolley release lever is snapped back to its original position), power
is restored and Opener is activated.
6. Mechanical Door Lock: When properly adjusted, opener locks door in closed position preventing unwanted entry.
7. Easy Connect Continuous Monitor Entrapment System: System allows quick and easy installation of “Silent Guard”
Photo Eye System while control circuitry monitors these devices continuously for proper operation.
8. Constant Contact to Close: For utmost safety if Photo Eye system fails constant contact of mechanical push button is
necessary to close door. In this mode of operation, a radio transmitter cannot be used to close door.
9. Momentary Contact to Close: Single touch to Radio Transmitter or Wall Button will allow door to close as long as
Silent Guard Photo eye system is operational.
10. Photo Eye System: An invisible infra-red beam of light guards the door opening and reverses a downward moving
door if the beam is broken by a stationary or moving object. If the beam is broken, the opener will beep for 20
seconds. Motor control circuitry constantly monitors the Photo Eye System for proper operation.
11. Digital Radio Control: Built in allowing over 1.6 million private codes, easily selected without use of tools. Bright
transmitter LED indicates operation and monitors battery condition.
12. Auto Force Learning: After setting the Up Limit and Down Limit is complete the door will run once from the Up Limit to
the Down Limit the data from this is stored in the memory. The red and green LED turn off and the opener beeps 3x,
the learning is then complete.
13. Soft Open/Close: The door soft open/close for a distance of 20-30cm depending on the size of the door being lifted.
14. Security Switch: When the Security Switch is activated the Door will not be able to operate. Signal from the Wall Box,
Transmitter, Push Button, and Up/Down button are all ignored. Light button will continue to function normally.

1. Raise and lower the door and check closely for areas of
sticking and binding. Check for loose hinges, wobbly
rollers, frayed cables and damaged or broken springs.
Contact a qualified garage door service person to make
the necessary adjustments.
2. Lift the door approximately halfway. When released,
the door should stay in that position. If door pulls open
or moves downward, the spring mechanism is not
adjusted properly. Contact a qualified garage door
service person to make the necessary adjustments.
3. When properly installed and adjusted the door will
remain clear of the opening, when allowed to rest at its
natural full open position. If door drifts up or down the
door is not adjusted properly. Contact a qualified
garage door service person to make the necessary
adjustments.
Door Test
Before beginning installation of the operator please complete the following test to insure that your door is balanced and
in good working condition. A poorly balanced door could cause severe personal injury and damage to the opener.
Always have a qualified garage door service person make any needed adjustments and/or repairs to your door before
proceeding with installation.
Do not install the opener until these adjustments and repairs have been made.

Warning: The Sensitivity System Reversing Test should be performed monthly to ensure that
this important system remains in proper adjustment
Testing the Safety Reverse System
Warning: Failure to Test Reversing System Could Result in Death or Serious Injury. Test This
System Once A Month.
To test the Opener Reversing Feature at floor level place a
solid object 5cm thick on the ground so that the center of the
door will come into contact with it. Close the door. If the close
force adjustments are correct, the door will reverse within one
and a half seconds upon contacting the object and travel to
the full open position. The door will emit short beeps
continuously for 25 seconds. If this does not occur, re-check
Limit Adjustments on pg.13 and Force/Sensitivity Adjustments
pg.14.
Note: Any time any adjustments are made to Limits or Sensitivity, You must retest the opener for the Reversing
Feature at floor level as outlined above.
Testing the Photo eye system
Start the door down and then place an obstacle approximately
20cm high by 30cm wide in the path of the beam. The Red
Pilot Light on the Silent Guard Photo Eye System should go
off. The door should stop for 1-1/2 seconds and reverse to the
full open position. The Opener will emit long beeps
continuously for 20 seconds. If the door is moving up and the
beam is broken, the door will continue up to full open. With
the door fully open and at rest, place the obstacle in the path
of the beam once again. Activate the Wall Push Button, The
Opener will revert to and remain in the Up limit position. Hold
the Wall Push Button to close the door (door will beep while it
travels to the down limit position).
*Auto Close Timer is only available with the Photo Eye
System present.
Warning: A damaged or malfunctioning Photo Eye System can enable a garage door to close
on people or property, causing serious injury or even death. Perform this test
monthly to ensure proper operation.
NOTE: If the garage door travels more than 5cm in a downward path after releasing the button, the Silent Guard
Photo Eye System is malfunctioning. Check all electrical connections and alignment of the Photo Eye System.

Make Sure That:
1. The front and rear mounts for the opener are sound and secure and the rail is positioned correctly above the
high arc of the door and that the opener is positioned over the door action centerline.
2. For sectional doors and tilt doors, the position of the door arm with the opener closed, is such that its connecting
point on the trolley is 12cm to 20cm behind its connecting point on the door bracket. The door arm should never
be perfectly vertical when the door is in the closed position (there should be an angle of 15-20°).
3. The emergency release knob and cord are secured to the emergency release lever on the trolley. The knob is
located 180cm above the floor and requires no more than 20kgs pull to actuate. The trolley and release
mechanism are properly lubricated. Recommend: Silicone based lubricant
4. The standard push button is in such a position and at such a height that it can only be actuated by an adult. The
caution label is prominently displayed next to the push button.
5. All wiring is correct to code. There is ground continuity in the supply. The ground prong on the power cord is
intact.
6. All ropes have been removed from the door, and any lock mechanisms removed or disabled. The door moves
freely without binding when operated manually. The door is correctly balanced and lubricated. All door hardware
is secure and sound. The sensitivity has been adjusted to minimum force. The appropriate warning sticker has
been affixed to the door.
7. The door reverses on obstructions to within 5cm of the floor. The floor beneath the closed door provides uniform
contact.
8. The manual is attached to the wall near the push button.
9. On doors with extension type springs, safety restraint cables have been installed through the springs.
10. There is surge protection on the power line to the opener.
***Operators recommend photo eyes to be installed on all garage doors for added safety***
Final Installation

19
1. Never permit children to play with or operate the garage door opener either from the wall station or the remote
controls. Keep radio transmitter locked in the car. Misuse of the push button or transmitter could result in serious
injury or even death.
2. Open the garage door with the remote controls only when the garage door is fully visible to you and clear of all
obstructions. The garage door should be kept in sight until it is completely open or closed and you are certain that the
garage door opener has shut off.
3. Attempting to exit the garage through the garage door opening, while the door is in motion, is a very dangerous
activity that could result in serious injury or even death.
4. Children and pets should always be clear of the door opening while the garage door is in motion.
5. Check the safety reverse mechanism at least once a month to make sure that it will reverse with the minimum amount
of force. Also check to be sure that the door will reverse within 5cm of the floor. See p.14.
6. Check the manual operation of your garage door at least every 90 days to be sure that it is operating smoothly and
does not bind or stick. Tighten all bolts on the door and visually check all hardware including springs for wear of
damage. Caution: If service is needed contact your local garage door service person.
7. Do not decrease the safety reversing sensitivity mechanism to overcome a damaged or poorly operating door. This
will adversely affect the operation of the safety reverse mechanism which could result in damage to the door,
personal injury or even death.
Caution: Never operate the door opener if the reversing mechanism is not functioning properly.
8. Whenever possible, the manual disconnect should only be used when the door is fully closed. Caution: Extreme care
must be taken whenever the disconnect cord is pulled with the door partially open. Weak or broken springs may allow
the door to fall rapidly resulting in property damage, personal injury or death. If a broken spring is evident, contact
your local garage door service person immediately before disconnecting the door from the opener. Never attempt
servicing a broken spring.
9. Always disconnect electrical power supply to the opener when performing any maintenance or service to the opener
or garage door. Failure to do so could result in electrical shock, property damage, personal injury or death.
10. If any damage to any mechanical or structural component of the opener is observed, discontinue use and contact
your local garage door service person immediately.
11. If the door auto reverses, please ensure there is no obstruction to the track or door.
