Sanitation Requirements
The Curtis G3 Brewer is Factory Pre-Set and Ready to Go… Right from the Box.
Following are the Factory Settings for the G3 Combo Brewer.
• Brew Temperature = 204°F
• Brew Volume = Set to dispensing vessel requirements (2.2 liters)
Generally there will never be a reason to change the G3/Gold Cup Series default settings. However, should you need to make slight
adjustments to meet your brewing needs, programming instructions are provided later in this manual.
System Requirements:
• Water Source 20 – 90 PSI. Minimum ow rate of ½ gpm (1 gpm preferred ow rate).
• Electrical: See electrical schematic on page 6.
SETUP STEPS
The unit should be level (left to right and front to back), and located on a secure counter top. Connect a water line from the water lter to
the brewer.
NOTE: A water ltration device must be used to maintain a trouble-free operation. (In areas with extremely hard water, we suggest
that a sedimentary and taste & odor lter be installed.) This will prolong the life of your brewing system and enhance coffee quality.
1. A 1/4” Flare has been supplied for water line connection. Use tubing sized sufciently to provide ½ GPM (preferred ow rate is 1gpm).
2. Connect the unit to an appropriate electrical power circuit.
3. Turn on the toggle (STANDBY/ON) switch behind the unit. The heating tank will start to ll. When the water level in the tank rises
to the correct volume, the heating element will energize automatically. With G3 tea brewers there is no danger of element burnout
caused by an empty tank.
4. The heating tank will require 20 to 30 minutes to reach operating temperature (204°F) as indicated by the READY-TO-BREW LCD
readout.
5. Important: Run one full brewcycle, to purge the water lines and valves of air. Five seconds of dilution water at the beginning of each
brewcycle is normal pre-programmed operating behavior.
NSF International requires the following water connection:
1. A quick disconnect or additional coiled tubing (at least 2x the depth of the unit) so that the machine can be moved for
cleaning underneath.
