Specifications

Pre-Installation Notes

The operator can be fitted to either the RIGHT or LEFT hand side of the roller door. Ensure sufficient side clearance as listed below:

Ensure a properly earthed mains supply socket is adjacent to the fitting location. If installing concurrently with a new door, consult the door installation instructions. For retro-fitting, verify the door operates smoothly and is balanced. Special care is needed if re-tensioning the door; do not loosen both "U" bolts if the door is under tension.

Important Notices & Safety Rules

IMPORTANT: READ THESE INSTRUCTIONS CAREFULLY PRIOR TO COMMENCING INSTALLATION.

This Automatic Opener is designed for years of trouble-free use when installed and operated properly.

SAFETY RULES:

• Keep the garage door balanced. Repair any sticking or binding doors. Garage door components are under extreme tension and can cause serious personal injury; do not attempt adjustment yourself. Call professional service.
• Do not wear rings, watches, or loose clothing during installation or servicing.
• Installation and wiring must comply with local building and electrical codes. Connect power only to properly earthed mains.
• The safety reverse system test is crucial. The door must reverse when obstructed during closing. Improper adjustment can lead to serious injury. Test monthly and adjust as needed.
• Do not install in damp or wet spaces.
• Use the Emergency Release handle to disengage the motor drive ONLY when the drive is switched OFF and the door is fully closed, if possible.
• Do not use sensitivity adjustments to compensate for binding doors. Excessive sensitivity can impair the Safety Reverse System or damage the door.
• Disengage all existing garage door locks to prevent damage.
• Install additional push buttons where the door is visible but out of children's reach. Do not allow children to operate buttons or remotes, as serious injury may result.
• CAUTION: Activate the operator only when the door is in full view, free of obstructions, and properly adjusted. Do not enter or leave the garage while the door is in motion. Keep children away from the door.
• Disconnect electric power before making repairs or removing covers.
• IMPORTANT: Attach the provided caution label to the rear of the garage door as a reminder of safe operating procedures.
• NOTE: 1. Move the door gently when disengaging the unit. 2. Set the Direction of Operation (L/R) correctly before use.

IF THERE IS ANY PROBLEM, PLEASE CONTACT YOUR LOCAL SUPPLIER.

Installation Instructions

1. Fit the anti-coning collar TIGHT TO SHAFT against the drum at the opposite end of the curtain to the motor, using the supplied nuts and bolts as shown in Figure 1. [Diagram: Figure 1 shows an anti-coning collar fitted to a shaft.]
2. Roll up the door with at least 100mm of curtain hanging down in the tracks.
3. Ensure the U-bolt on the end of the door opposite the opener is tightened securely. This U-bolt holds the spring tension once the other U-bolt is released.
4. Slide the drive unit onto the shaft as shown in Figure 2. Ensure the drive forks engage fully with the narrowest spoke on the drum wheel. [Diagram: Figure 2 shows the drive unit engaging with the drum wheel.]
5. For ease of installation, the sun gear can be disengaged for free rotation by pushing the Emergency Release handle downwards. To re-engage and lock the sun gear, push the handle upwards. [Diagram: Emergency Release handle shown with 'PUSH-ENGAGE' and 'PULL-DISENGAGE' labels.]

Caution: Opener must be ENGAGED before proceeding further installation.
