Sanitation Requirements
NSF International requires the following water connection:
1. A quick disconnect or additional coiled tubing (at least 2x the depth of the unit) is required so
that the unit can be moved for cleaning.
2. This unit must be installed with adequate backow protection to comply with applicable federal,
state and local codes.
3. Water pipe connections and xtures directly connected to a potable water supply shall be sized,
installed and maintained in accordance with federal, state, and local codes.
3. Connect the unit to electrical circuit with appropriate amperage rating; refer to serial tag on the machine and
local/national electrical codes to determine circuit requirements.
4. Once power has been supplied to the unit, ip the toggle switch to the ‘ON’ position (located on the rear of
the unit), the water tank will begin to ll. When the water level in the tank reaches the probe, the heating
element(s) will turn on.
5. Water in the heating tank will require approximately a half hour before reaching operating temperature (factory
setting of 200°F). Where applicable, turn on the Universal Control Module (UCM). When the unit reaches
operating temperature, it will display “READY TO BREW”.
NOTE: A water ltration system must be used to help maintain trouble-free operation. Air must be
purged from the cartridge prior to connection to equipment. In areas with extremely hard wa-
ter, we highly recommend the use of a Curtis approved water lter. For our full line of lters, please
log on to www.wilburcurtis.com.
SETUP STEPS
1. The unit should be level (left to right - front to back), on a secure surface.
2. Connect the water line to the water inlet tting on the rear of the unit. Water volume ow to the machine
should be consistent. Use tubing sized sufciently to provide a minimum ow rate of one gallon per minute.
NOTE: Electrical source should have a minimum 30A internal common trip circuit breaker between
the brewer and the main supply, which breaks all poles with a contact separation of at least 3 mm.

2
1. Brewer should be ON (conrm at the rear toggle switch). When a screen saver is running, touch the screen to restore the control screen.
This screen should read Ready to Brew.
2. Place an empty cup under the brew cone.
5. Slide the lled brew cone into the brew
rails on the brewer.
3. Place a clean lter into the brew cone. 4. Fill brew cone with the proper amount of
ground coffee.
COFFEE BREWING INSTRUCTIONS
WARNING TO AVOID SCALDING, Do not remove brew cone while brew light is ashing.

enter the brew code a brew cycle starts.
Refer to page 8 for more information about the
Brew Code.
During the brew cycle, an animated coffee
cup icon will appear on the screen and a
brew timer will count down the time remain-
ing on the brew cycle.
Your Curtis Gold Cup Series is Factory Pre-Set for Optimum Performance.

Brew Access Code

There are two methods that can be used to change the default settings on G4 brewers. They can be programmed at the brewer by
the touch screen universal control module (UCM) or the settings can be changed using the USB (Universal Serial Bus) data port
on the side of the brewer. Using the USB connection and a ash memory data storage device will easily reprogram the settings
simply by copying data.
The ash drive can upload or download the entire setting from one G4 brewer, into another G4
brewer. This eliminates the need to walk through the usual steps in reprogramming that would
be required when you use the touch screen to make a change. This is an advantage for a
service technician when standardizing the program settings on multiple G4 brewers.
Use a USB drive with USB 2.0 support and a type-A USB connection. Storage capacity should
be 2 GB minimum (reference the illustration on page 2).
IMPORTANT: The ash drive must be completely blank. Before starting, please erase any les
that may be in the USB drive.
SOFTWARE INFORMATION TRANSFER
UPLOAD TO USB
1. Make sure the brewer is on. Determine that the G4 brewer you wish to copy is properly programmed for your desired settings.
2. Connect an empty ash drive into the USB port on the brewer. The UCM on the brewer will upload all of the particular setup
data onto the ash drive. The yellow LED on top of the touch screen will light indicating that data is transferring. This will only
take a second to complete.
DOWNLOAD TO BREWER
1. Select the brewer you wish to make the program changes on. The brewer should be on.
2. Plug the loaded ash drive into the USB port on the brewer. The data copied from the rst G4 brewer will automatically down-
load, overwriting all the settings that were on the second brewer.
3. The red LED on the UCM will indicate that the download is in process. This will only take a second.
4. Once the download is complete, the UCM will reboot in order for the changes to take effect.
5. Remove the ash drive. The download is complete. The data on the ash drive can be downloaded into as many G4 brewers
as needed.
USB – Easy Programming

15
USB – File Transfer
This screen will be presented whenever the USB ash is inserted, as long as UCM is showing main brew screen and is not cur-
rently brewing.
The default action is “No action”.
The UCM will always create a backup on the USB ash drive before downloading settings/recipes or screensaver.
If a rmware update le is present on the USB ash, the rmware update procedure will be started BEFORE this screen is shown.
Case 1: Settings/recipes le
present, screensaver not pres-
ent. User has selected ‘Down-
load from USB’ for settings/
recipes le.
Case 2: As above, but user has
selected ‘Upload to USB’ for set-
tings/recipes le.
With this action, the overwrite
warning appears.
