Important Rail Information

The operator cannot function without the correct LiftMaster trolley rail.

Rail selection depends on the garage door height and application. Before ordering, confirm that your existing rail is compatible with the ATSWT operator or purchase the proper LiftMaster rail separately.

Do not assume that a residential LiftMaster rail, belt-drive rail or rail from another operator model will fit this unit.

Compatibility Notes

Use this operator only with a properly balanced, compatible standard-lift sectional door.

It is not intended for:

• Rolling steel doors
• High-lift or vertical-lift sectional doors
• One-piece doors where prohibited by the installation instructions
• Sliding or swing gates
• Heavy industrial or high-cycle commercial applications
• Doors with damaged, improperly adjusted or undersized spring systems

Compatibility should be confirmed using the door height, door type, existing rail model, operator generation, electrical supply and required safety accessories.

Installation and Safety

A garage door operator must be installed on a properly balanced and mechanically sound door. Springs, cables, drums, rollers, tracks and related hardware should be inspected before installation.

Required monitored safety devices must be installed and correctly aligned. Never use a new operator to compensate for a door that is excessively heavy, binding, damaged or improperly balanced.

Commercial operator installation, electrical connections and garage door spring adjustments should be completed by a trained garage door professional.
