device. The owner should follow these instructions to determine whether the door is operating
properly and should immediately call for service if there is any malfunction. All installation
changes and adjustments must be made by qualiied, NABCO trained technicians.
Note: As an Option, the GT-1400 Fold door can be certiied to have a Hurricane High Impact Compliant
Version manufactured to meet the High Velosity Hurricane Zone (HVHZ) requirements of the Florida
building codes.
