• Verify that the unit is plugged in.
• Ensure that the rear toggle switch is in the ON position.
• Check power to control board by checking if lights on control board are lit.

• Make sure “Ready to Brew” light is on, or the display reads “Ready to Brew”.
• Ensure water in the tank is touching the water level probe. The inlet valve energizes when water level drops below the probe.
• Check for 120V at the dump valve while pressing the brew button.

• G3 Equipment:
— For 120V operation, connect neutral jumper wire from N to C on power block. Power connection:
L1, N & G
— For 220V operation, neutral jumper wire needs to be disconnected from “C” on power block and
capped. Power connection: L1, L2, N & G
• Decanter Brewer Equipment (Alpha D & DS):
— For 120V operation, cap brown wire and connect black wire to position “C” on power block. Power
connection: L1, N & G
— For 220V operation, cap black wire and connect brown wire to position “C” on power block. Power
connection: L1, L2, N & G
• Air Pot Brewer (D500AP):
— For 120V operation, cap red wire and connect brown wire to position “C” on power block. Power
connection: L1, N & G
— For 220V operation, cap brown wire and connect red wire to position “C” on power block. Power
connection: L1, L2, N & G

• If using 220V power, white wire should be capped. If white wire is uncapped and connected to C on the power block, it will cause the unit to boil when connected to 220V power. Refer to power hookup label inside unit for detailed instructions.

• Verify that the water supply to the brewer is on.

• Check warmer resistance. 120VAC/less than 150ohm. 220VAC/less than 300ohm.

Curtis FreshTrac is a revolutionary management system that provides operators with a fool proof visual freshness monitor on coffee decanters.  The system is independent from the brewer requiring no wired connection.

At the touch of the brew button, the FreshTrac monitor begins counting to its operator set freshness time.  When the coffee has exceeded its freshness time, the monitor begins to blink red, indicating a new brew should be made.

Yes.  Freshness time can be adjusted via the Alpha control board.

Yes. The processor inside the visual monitor is completely encapsulated, protecting it from steam, water and impact.

The monitor itself is not designed to be repaired, but replaced when the battery is exhausted. The monitor can be removed and installed onto a new glass bowl should anything happen to the current bowl.

The battery life is rated to last two years under normal operating conditions.

Yes, like the rest of the Curtis Gold Cup Series of coffee brewers, the FreshTrac System is capable of brewing to the SCAA’s Golden Cup Standard.

The Curtis IntelliFreshTM System is patented technology that allows the brewer to communicate with the satellite servers in order to monitor holding time and temperature, resulting in the freshest possible cup of coffee. It offers three main design benefits:

• Auto Adjusting Satellite Temperature Control – Coffee freshness is a component of time and temperature. Inside each IntelliFreshTM Satellite Server is a sensor that automatically monitors the temperature of the coffee. By following a proprietary algorithm, the server automatically maintains the coffee temperature for optimal taste and freshness. Low-wattage warmers cycle on and off to gently maintain temperature between preset parameters. This constant monitoring of temperature prevents coffee from “cooking”, preserving its freshness and taste.


• Quality/Freshness Timer – After the brewing cycle has been completed, a timer begins to countdown. Settings range from 20 minutes to 4 hours (Default is 2 hours). During the countdown time the LED will stay illuminated; after the time has expired the LED will flash.


• Auto-Off Warmers – Warmers and the LED satellite light will automatically shut off after a predetermined time setting has expired. Settings range from 1 to 12 hours. (Default is 12 hours)

Each IntelliFresh Satellite Server has a state of the art processor located inside the server that plugs into the brewer. Communication is automatically established every time the server is placed on the IntelliFresh Brewer. When the server is docked and a new brewing cycle is started, any new settings from the brewer are automatically updated into the satellite server’s processor.

Yes. The processor inside the satellite server is completely encapsulated, protecting it from steam, water, heat and impact. Other manufacturers choose “open board” technology, meaning they have no barrier to protect the electronic components inside their servers from damage. In addition, IntelliFreshTM Satellites have been designed so that the internal structure and material composition allow water to drain, preventing damage associated with moisture. Insulation material acts like a sponge when it gets wet, absorbing and retaining water. We chose not to insulate our servers for this very reason. Other manufacturers insulate their servers, increasing the likelihood of water damage.

We know through testing and research that insulation will encourage moisture retention inside the satellite body during the brewing or cleaning cycles. While brewing, serving or cleaning, coffee or water can easily seep into the interior of the unit and absorb into the insulation material. As we designed our IntelliFreshTM Satellites, we chose not to insulate in order to prevent moisture and liquid from damaging the insulation and unit.

Temperature changes are easily set on the brewer’s control board with independent Left Warmer and Right Warmer settings. Pre-programmed temperatures for Low (182°F), Medium (185°F) and High (188°F) are pre-set at the factory, but can be changed to fit the customer’s preference. The IntelliFresh Satellite server does not require disassembly to change temperature settings, making it convenient and hassle free.

Yes. Time and temperature settings are stored in the processor of the IntelliFresh Satellite. The programmed settings travel with the server.

“Back to Back” brewing is a term commonly used for brewing one batch of coffee immediately after another. Also known as recovery rate, the ability of any brewer to offer “Back to Back” brewing is dependant on many factors that include electrical configuration, brew volume and cold brew lock out settings.

With our electrical configuration, the IntelliFresh System is capable of providing the highest “Back to Back” brewing capability in the industry.

In the unlikely event that an IntelliFresh Satellite stops functioning, built-in self-diagnostic features helps identify the root problem. This will help the service provider in making a faster assessment of the problem, resulting in shorter downtime and lower service costs. The diagnostic features on the IntelliFresh Satellite indicate both heater and/or sensor failure, the two most common failures found in warmers.

We understand that high quality coffee equipment is an investment. Should they need repair, we designed the IntelliFresh Satellites to be easily repaired by a qualified service technician. Modular design takes the complexity out of repair, resulting in lower downtime and service costs.

We feel plastic is superior for several reasons:

• Easier to clean and maintain – Dishwasher safe and one-piece design with no removable wire basket to lose, makes it easier to clean and maintain.

• Easier to handle – because plastic is lighter in weight and cooler to the touch, it is easier and safer to handle. This is especially important after a large volume brew when the coffee grounds are soaked with water, adding to the weight.

• Better temperature control – Because stainless steel is a high temperature conductor, metal brew cones tend to be cold or cool down thus drawing heat from the coffee. Plastic will not impact the brewing temperature.

A stainless steel brew cone is an available option.

Yes.  Like the rest of the Curtis Gold Cup Series of coffee brewers, the IntelliFresh System is capable of brewing to the SCAA’s Golden Cup Standard.

• 2 gallons dilution to 1 gallon concentrate.

• No, they use the same heating tank to dispense hot water.

• To prevent cross contamination between the coffee and tea.
• The brew cone for tea has a strainer and, if used for brewing coffee, it would cause brew cone to overflow.

• Brewing tea at a higher temperature allows for greater extraction of flavor.
— Most black teas are brewed at approximately 204°.
— Green tea can be brewed at a lower temperature, but should not be lower than 170°.
— Most herbal infusions are brewed at approximately 204° and above.

• Brew water only to preheat servers.

• When a global recipe is used, all of the settings, (pre infusion, bypass, pulse brewing, etc.) are built into the recipe, eliminating the need of setting these manually. The global recipes simplify profile settings for gourmet results every time.
