Board to an acrylic Lens at the tip of the Spout; a solid green LED indicates dispense activity and a red blinking LED indicates
low battery life.
Battery Pack — Water-resistant, plastic material holds 4 Alkaline “D” Cell Batteries (not included). ANSI-134A, IEC-LR20
Designation, which includes most standard battery manufacturer’s D-Batteries. Optional 6V AC Adapter with U.S. Plug

OPERATION:
To fill dispenser, insert tip of standard key provided into opening of the concealed locking mechanism in the dispenser body to
disengage door for quick and easy top filling. Lid will open for filling dispenser with bulk foam hand soap. Rotate door counterclockwise to close and lock in place.
To activate dispenser, place hand under spout near the sensor for approximately 1 second. Spout will dispense foam that is
generated by mixing 0.1 to 0.7ml of liquid foam soap. The texture of the foam can be adjusted by rotating the control dial. The
texture may vary depending on the type of soap used.
Designers Note: Bobrick Foam soap dispensers are designed to dispense commercially marketed all purpose foam hand soaps and
antibacterial foam soaps containing PCMX and/or Triclosan. Acceptable foam soaps need to have a viscosity of less than 100cPc
(centipoise).
