Frequently Asked Questions - GR-2.3 Fetco

How do I descale the Fetco GR-2.3 coffee maker?

Use a commercial descaling solution mixed with water as per manufacturer instructions. Run a brew cycle without coffee, then rinse with two cycles of fresh water. Repeat every 3 months to maintain performance.

What type of filter does the GR-2.3 use?

It uses standard commercial paper filters (12-14 cup size) or a reusable nylon filter (optional). Ensure the filter is properly seated in the brew basket.

Can I use a thermal carafe with this brewer?

Yes, the GR-2.3 is compatible with Fetco airpots and thermal decanters. Use the appropriate adapter kit if needed.

How do I adjust the brew temperature?

Access the internal control panel (unplug first). Use the temperature adjustment potentiometer to set between 195°F and 205°F. Refer to the manual for precise calibration.

Why is my coffee not brewing fully?

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.

2. Install the grinder in selected location making sure surface is level, and that grinder will fit. Caution: Never push equipment against cords or wall outlets.

3. Remove cord from inside hopper and plug into the back of the grinder.

4. Before plugging grinder into 120 volt, 15 amp. wall outlet make sure outlet is not overloaded, a dedicated circuit is preferred.

5. Following the operating procedures below test grinder for proper operation.

6. If you need further assistance please call our Technical Support Dept. at 800-338-2699 or e-mail [e-mail].

Warning: To prevent electrical shock, this unit must be properly grounded.

Operating Instructions

1. Turn the on/off switch to the on position.

- The power switch will illuminate to indicate that the grinder has power.

1. Fill the hopper(s) with whole coffee beans.

2. The GR-2 models have two 5lb. removable hoppers. The hoppers must sit squarely on the floor of the hopper chamber. Before placing the hoppers inside the hopper chamber, make sure the chamber is clear of stray whole beans and debris, or the hoppers will not sit properly.

3. Both hoppers with their covers must be in place before operating the grinder.

4. Place the brew basket with paper coffee filter in the plastic holding arms.

5. The plastic arms will hold all FETCO brew baskets up to 16" X 6"; and will fit most other manufacturers' brew baskets.

6. For brew baskets that do not fit into the plastic arms, place the coffee filter on the lower shelf and grind directly into the filter.

7. Press the desired portion switch.

• See the Programming section for instructions on setting the various batch sizes.

1. Allow grinder to complete its cycle then remove brew basket from plastic holding arms.

Cleaning:

a) Use stainless steel cleaner on all stainless steel surfaces. (Never use abrasives on these surfaces.)
b) Use damp cloth on other surfaces. Use mild detergent as needed.
c) Removable hoppers on GR-2 models are dishwasher safe (the covers are not).
d) After washing hoppers FETCO recommends hand drying them.

Warranty

All FETCO grinders come with a limited warranty. Warranty service must be authorized by the Technical Support Department. A Return Authorization number will be issued for all parts replaced under warranty.

Principles of Operation

GR-1

When one of the start switches is pressed, the timer energizes the grinding motor. The coffee beans are fed into the grinding chamber by a rotating auger spring. When the timed cycle is complete, voltage is removed from grinding motor.

The power/stop switch is used only when it is necessary to interrupt the grind cycle before the cycle is finished.

GR-2

When one of the start switches is pressed, the timer simultaneously energizes the grinding motor and the hopper solenoid. The hopper solenoid opens the guillotine on the bottom of the hopper, which allows the coffee beans to drop into the grinder. The coffee beans are fed into the grinding chamber by a rotating auger spring.

When the timed cycle is complete, voltage is removed from the hopper solenoid and the guillotine closes, stopping the flow of beans out of the hopper. The auger spring continues to feed any remaining beans into the grinding chamber.

Several seconds after the guillotine closes, voltage is removed from the grinding motor. This delay ensures that all beans have passed through the grinding chamber, preventing cross contamination of different coffees.

The motor delay is factory set at 20 seconds, but can be adjusted if necessary. (See Programming section.)

The power/stop switch is used only when it is necessary to interrupt the grind cycle before the cycle is finished.

Grinder Foreign Object Protection

FETCO coffee grinders feature two types of overload protection to prevent damage to the unit if a foreign object enters the grinding chamber and stalls the motor.

• The control board is equipped with a thermal breaker with an audible alarm that will cut power to the motor if the control board overheats.
• The motor is equipped with a thermal breaker (no alarm) that will cut power to the motor if the motor overheats.

Once the foreign object is removed and the unit cools down, the thermal breakers will automatically reset.

Warning: If this occurs DO NOT TRY TO FIX THIS PROBLEM YOURSELF. Immediately unplug the grinder and call a qualified service technician.

Grind Adjustment

1. Empty the hopper(s).
   GR-1: Scoop out as many beans as possible. Lift the window up and sweep out the remaining beans.
   GR-2: Remove both hoppers and dump the beans out. Place both hoppers back in grinder.
2. Press one of the large portion switches. This will clear the grinding chamber of any remaining beans.
3. Remove the front cover. There are 2 screws in front and 2 underneath near the coffee outlet.
4. Using a 7/8" or 22 mm wrench turn the retaining nut counter-clockwise at least one turn.
5. Using a 3/8" to 1/2" standard screwdriver turn the adjustment screw clockwise for a finer grind, counterclockwise for a coarser grind. Note: Do not exceed more than a 1/4 turn in either direction.
6. Turn retaining nut clockwise, locking adjustment screw in place.
7. Grind a small amount of coffee beans to test the setting. Repeat the above steps if necessary.

To reset the grind setting to the factory default:

• Follow steps 1 - 4 of the grind adjustment procedure.
• Turn the adjustment screw clockwise until the grinding discs touch, then back off slightly.

- Using a marker, mark the twelve o'clock position of the adjustment screw.

- Turn the screw counter clockwise to just past the four o'clock position.

- Turn retaining nut clockwise locking adjustment screw in place.

- Test by grinding a small batch.

COARSE

FINE

Note: It may be necessary to adjust the grind time to compensate for the new grind setting. A finer grind will produce less ground coffee per minute and a coarser grind will produce more ground coffee per minute.
