WARNING: To reduce the risk of severe injury or death:
For detailed safety information, refer to the full safety guidelines provided with your product packaging.
Verify that all components are present before beginning installation.
Proper installation is crucial for safe and reliable operation. It is recommended to have this unit installed by a qualified professional.
Assemble the 7-foot belt drive rail according to the diagrams in the separate installation guide. Ensure all sections are securely connected and the belt is properly tensioned.
Securely mount the motor head to the ceiling joists or appropriate structural supports above the garage door. Use the provided mounting hardware. The motor head should be centered with the garage door.
Plug the power cord into a grounded 120V AC outlet. Ensure the outlet is not controlled by a switch.
Install the safety sensors (photo eyes) on each side of the garage door opening, no higher than 6 inches from the floor. Ensure they are aligned and the indicator lights confirm proper connection.
Follow the programming instructions to set the open and close limits for your garage door. This ensures the door stops at the correct positions.
Program your remote controls and wireless keypad to operate the opener. Refer to the specific programming section for detailed steps.
Press the designated button on your remote control to open or close the garage door. The door will stop if the button is pressed again during movement.
Press the large button on the wall control panel to operate the door. The panel may also include a light button to control the opener's integrated LED lighting.
Enter your personal identification number (PIN) on the keypad, then press the ENTER button to operate the door.
In case of a power outage, pull the emergency release cord (usually red) to disconnect the door from the opener. This allows for manual opening and closing of the garage door. Re-engage the door by pushing the lever back into place once power is restored.
Regular maintenance ensures optimal performance and longevity of your garage door opener.
