INTELLIFRESH® FEATURES

IntelliFresh Function and Features

The LED coffee level gauge on the front of the dispenser is also the indicator for the IntelliFresh Quality Timer system. When the quality timer is set to on (default), it alerts you to when the coffee has exceeded the programmed freshness time. The Quality Timer is activated via a signal sent through corresponding connectors from the brewer to the dispenser. When the warmer (automatically) shuts off, the coffee level gauge turns blue, provided there is still coffee in the dispenser. Otherwise the LEDs turn off completely.

See the PROGRAMMING GUIDE to change the Quality Timer settings, including freshness (quality) time and LED color.

| NOTE: After the brew cycle is complete, if the GEMX dispenser is transferred from the brewer to a Curtis IntelliFresh warmer stand, the following dispenser settings will remain the same: Quality Timer, Warmer Default (heat setting) and dispenser (Intellifresh) Color Scheme.

CLEANING INSTRUCTIONS

Cleaning the Dispenser (Daily)

The following cleaners are required to properly maintain the dispenser:

• Mild solution of dish-washing detergent and warm water
• TABZ™ Z95 Coffee Equipment Cleaner Tablets (Curtis PN WC-79000)
• One-Pro Beverage Equipment Cleaner (Curtis PN WC-79001)

| WARNING: DO NOT immerse the dispenser in water or any other liquid. Do not place the dispenser in a dishwasher. Doing so will void the warranty. Do not use harsh powders or cleansers containing chlorine. Do not use a wire brush or scouring pad to clean inside the liner. To avoid damage, DO NOT use a brush to clean the faucet or the inside of the faucet shank (outlet).
---|---
| IMPORTANT: Clean the dispenser daily to avoid the build up of coffee oil residue on the Intellifresh® sensors inside the liner. Residue build up may cause the Intellifresh indicator to malfunction.
---|---

Cleaning the Liner

1. Remove the dispenser from the brewer and remove the lid. Set the lid aside. Rinse out the liner.
2. Wash – Prepare a mild solution of detergent and warm water. Wipe the exterior surfaces of the dispenser with a sponge moistened with the detergent solution to remove spills and debris. Fill the liner with the detergent solution. Take a soft nylon brush and scrub out the stainless steel liner.
3. Rinse – Rinse out the liner with clean, warm water.
4. Sanitize – Drop one TABZ Z95 tablet into the liner. Fill to the top with hot water (122°F/50°C min.). Stir the contents. Allow the liner to soak for 5 to 10 minutes.
5. Open the faucet and drain out the dispenser (to clean the faucet shank).
6. Fill the liner to the top with clean, warm water and drain through the faucet (to rinse the faucet shank).
7. Fill the liner to the top with water a second time and drain through the faucet.
8. Disassemble the faucet – Unscrew the handle/bonnet assembly from the top of the faucet and remove it. Inspect the seat cup for wear. Replace the seat cup if it is damaged.
9. Air Dry – Turn the dispenser upside down and allow to air dry.

TROUBLESHOOTING GUIDE

Dispenser Does Not Heat

NOTE: The dispenser heating element is designed to keep brewed coffee hot, but is not of sufficient wattage to reheat cold coffee.

1. First check to see if one of the LED bars on the dispenser is flashing an error code. The top LED bar flashing red indicates a bad heating element. The middle LED bar flashing red indicates a defective sensor circuit on the controller (replace the controller).
2. Check to see if the I ntell ifresh® LED on the front of the dispenser comes on at the beginning of the brew cycle. If neither the LED nor the warmer come on, then it can be assumed that there is no power to the dispenser. Make sure that power is being supplied to the lntellifresh (IF) connector on the brewer when th,e BREW button is pressed. The voltage varies based on the model, see the ELECTRICAL SCHEMATIC. If power is present at the connector, check the connector contacts. If power is not present at the IF connector, trace the circuit back to the control module to see if it is supplying power to the IF connector.
3. Check the contacts on the dispenser IF connector to make sure that they are making good contact with the connector on the brewer.
4. If the dispenser is receiving power from the IF connector and there are no error codes, suspect the controller.

None of the LED Bars Light, Regardless of Coffee Level (Warmer is Working OK)

NOTE: If the dispenser is empty, the LED bars will not light.

1. Check for chassis ground, UPM ground and UPM 5 Volts into the LED array (see LED pin assignment on dispenser schematic).
2. If power and ground are being supplied to the LED array and none of the LED sections come on when the dispenser is full, the LED array is probably bad.

Some LED Bars Do Not Light
Short the probe wire for the LED section that is not working to ground. If the section lights, check the probe connection. If the section does not light, the LED array is bad.

One or More LED Bars are Constantly On Regardless of Coffee Level

1. Clean the inside of the dispenser according to the CLEANING INSTRUCTIONS section to remove any residue build-up that may be causing a malfunction.
2. Check for a probe wire that is shorted to ground.
3. If the probe wires are OK, suspect the LED array.

lntelliFresh Feature Does Not Work (Warmer OK)

1. Check to make sure that the UCM lntelliFresh settings on the brewer are correct.
2. Check the continuity of the UPM/LED communication wire.
3. Replace the LED module. If the lntel liFresh feature does not work properly after replacing the LED module, the dispenser UPM module is probably bad.
