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fed-
eral, 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 an electrical circuit with appropriate amperage rating; refer to the serial tag on the machine
and local/national electrical codes to determine the circuit requirements.
4. Once power has been supplied to the unit, turn 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. The water in the tank will require approximately one half hour before reaching the operating temperature
(factory set to 200°F). 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
water,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 INSTRUCTIONS
1. The unit should be level (left to right - front to back), on a secure surface.
Install the leg support (optional on model CGC) before leveling. Install it
according to the instructions on page 23.
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cient
to provide a minimum ow rate of one gallon per minute.
NOTE: Electrical source should have a minimum 30 A 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.
WARNING: Use the
leveling legs to level the
brewer only. Do not use
them to adjust brewer height. Do not
extend them higher than necessary.

Brew Access Code

There are two methods that can be used to change the default settings on Curtis Generation 4 (G4) brewers. The settings can be
programmed at the brewer using the universal control module (UCM) touch screen or using the universal serial bus (USB) data
port on the side of the brewer. The brewer can easily be reprogrammed by using the USB connection to copy data from a USB
ash drive.
The ash drive can be used to copy all the settings from one G4 brewer to another G4 brewer. Doing so eliminates the need to
manually go through all the usual programming steps using the brewer touch screen. This
allows program settings to be standardized on multiple G4 brewers.
Use a ash drive with USB 2.0 support and a type-A USB connection. Storage capacity
should be 2 GB minimum.
IMPORTANT: The ash drive must be completely blank. Before starting, erase any existing
les on the ash drive.
SOFTWARE INFORMATION TRANSFER
UPLOAD TO USB
1. Make sure that the brewer is on. Determine that the G4 brewer you wish to copy programming from is properly programmed to
the desired settings.
2. Insert the empty ash drive into the USB port on the brewer. The UCM on the brewer will automatically upload all of its set-
tings data onto the ash drive. The yellow LED on above the brewer touch screen will light indicating that data is transferring.
The process will only take a second to complete.
DOWNLOAD TO BREWER
1. Select the brewer you wish to make the program changes to. 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 existing settings on the second brewer.
3. The red LED above the brewer touch screen lights indicating that the download is in process. The process will only take a
second to complete.
4. Once the download is complete, the UCM will reboot automatically so that the changes take effect.
5. The download is complete. Remove the ash drive. The data on the ash drive can be downloaded to as many G4 brewers as
needed.

Start
USB – File Transfer
The screen below will be present whenever the USB ash drive is inserted, provided that the UCM is showing the main brew
screen and is not currently brewing.
The default action is “no action”.
The UCM will always create a backup on the USB ash drive before downloading settings/recipes or a screen-saver.
If a rmware update le is present on the USB ash, the rmware update procedure will start BEFORE this screen is shown.
Case 1: Settings/recipes le
present, screen-saver not pres-
ent. User has selected ‘Down-
load from USB’ for settings/
recipes le.
Case 2: Same as above, but user
has selected ‘Upload to USB’
for settings/recipes le. With this
action, the overwrite warning
appears.
