Dimensions & Utility Connections Installation Warning: Read this User’s Guide before installing. Damage caused by improper installation will not be covered under warranty. 1. Inspect the container for visual or hidden damage. The carrier must be notified of any punctured or damaged cartons immediately.
Operating Procedures 1. Turn grinder on/off switch to the on position. • The power switch will illuminate to indicate that the grinder has power and is operational. 2. Fill the hopper(s) with whole coffee beans. • The GR-2 models have two 5lb. removable hoppers. These hoppers must sit squarely on the floor of the hopper chamber.
GR-2 The timer energizes the hopper solenoid; which opens the guillotine on the removable hopper, which allows coffee beans to drop into the grinding chamber. The timer also energizes the capacitor which energizes the motor. When the timer finishes its cycle, it removes voltage from the hopper solenoid, which closes the guillotine on the removable hopper.
