INSTALLATION INSTRUCTIONS
WARNING -
To reduce the risk of severe injury or death:

2) Install only on a properly operating and balanced door. A door that is operating
improperly could cause severe injury. Have qualified service personnel make
repairs to cables, spring assemblies and other hardware before installing the operator.
3) Remove all pull ropes and remove, or make inoperative, all locks (unless mechanically
and/or electronically interlocked to the power unit) that are connected to the door
before installing the operator.
4) Install the door operator at least 8 feet above the floor if the operator has exposed
moving parts.
5) Do not connect the door operator to the power source until instructed to do so.
6) Locate the control station: (a) within sight of the door, (b) a minimum of 5 feet above
the floor so that small children cannot reach it, and (c) away from all moving parts
of the door.
7) Install the Entrapment Warning Placard next to the control station and in a
prominent location.
