The purpose of this manual is to familiarize the installer and purchaser with the proper installaon and operaon of this system.
It is essenal that this equipment be properly installed and operaonal before the door is used by the public. It is the installer’s
responsibility to inspect the operaon of the entrance system to be sure it complies with any applicable standards. In the United
States, ANSI Standard 156.10 (Full Power) and ANSI Standard 156.19 (Low Energy) covers the GT20 Swing Door Operator Assembly.
Other local standards or codes may apply. Use them in addion to the ANSI standard. Both Full Power and Low Energy Swing door
Units are listed by UL according to UL325 and is idened as such on the label.
Instruct the building owners and operator on the essenals of the operaon of this device. The owner should follow these
instrucons to determine whether the door is operang properly and should immediately call for service if there is any malfuncon.
All installaon changes and adjustments must be made by qualied, NABCO trained technicians. Replacement labels and literature
may be obtained from local NABCO Entrances, Inc. Distributors. If the name of the local distributor is unknown, contact NABCO
Entrances, Inc. at 1-877-622-2694 for assistance.
The Swing Door Operator assembly is designed to be installed onto the top surface of the Door Frame, or Door Panel, or between the
Jamb Tubes under the Door Frame (OHC). This manual was created to oer step by step instrucons.

It is recommended to install a FAIL/SAFE electric lock on Swing doors using Inverse Swing Doors. During normal operaon, the
FAIL/SAFE lock applies connuous pressure to keep the Swing door in a fully closed posion. During a Power Failure, the FAIL/SAFE
lock automacally unlocks, thus allowing the Swing door to fully open.
Do Not install Fail/Secure electric locks on Swing Doors using Inverse Swing Doors. Fail/
Secure electric locks will not allow the Swing door to open during a Power Failure.
