3. Setup and Installation
The Hormann RollMatic External Roller Replacement Drive (Model 439591) requires assembly and professional installation. Follow these general steps:
- Preparation: Disconnect power to the existing garage door system. Secure the garage door in an open or closed position to prevent accidental movement.
- Removal of Old Drive: Carefully detach the existing drive unit from its mounting brackets and disconnect all wiring. Note the position and connection of each wire for reference.
- Mounting the New Drive: Position the new Hormann RollMatic replacement drive unit on the existing mounting plate or secure it to the designated area according to the original drive's configuration. Ensure it is level and securely fastened using appropriate hardware.
- Wiring Connections: Reconnect the electrical wiring to the new drive unit. Pay close attention to the wiring diagram provided with the product packaging to ensure correct polarity and connections. Incorrect wiring can damage the unit or pose a safety hazard.
- Limit Switch Adjustment: Once the drive is physically installed and wired, adjust the upper and lower limit switches to define the garage door's open and closed positions. Refer to the specific instructions provided with the drive for precise adjustment procedures.

4. Operating Instructions
Once installed and configured, the Hormann RollMatic External Roller Replacement Drive operates in conjunction with your existing garage door control system (e.g., remote control, wall switch).
- Opening/Closing: Press the designated button on your remote control or wall switch to initiate the opening or closing cycle of the garage door.
- Stopping: Press the button again during operation to stop the door at any desired position.
- Safety Reversal: The drive is equipped with a safety reversal mechanism. If the door encounters an obstruction during closing, it will automatically reverse to the open position. Ensure this feature is tested regularly.
- Manual Override: In case of power failure, locate the manual release mechanism on your garage door system (usually a red cord). Pulling this cord will disengage the drive, allowing you to manually open or close the door. Re-engage the drive once power is restored.
5. Maintenance
Regular maintenance ensures the longevity and safe operation of your Hormann RollMatic External Roller Replacement Drive. Perform the following checks periodically:
- Monthly:
- Inspect the garage door tracks, rollers, and hinges for any signs of wear, damage, or obstructions. Lubricate moving parts as recommended by your garage door manufacturer.
- Test the safety reversal mechanism by placing a small object (e.g., a roll of paper towels) in the path of the closing door. The door should reverse upon contact. If it does not, discontinue use and contact support.
- Annually:
- Check all mounting hardware for tightness.
- Inspect electrical connections for corrosion or loose wiring.
- Ensure the drive unit itself is clean and free from excessive dust or debris.
Do not attempt to repair the internal components of the drive unit. Contact qualified service personnel for any repairs.
