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 Iced Tea Brewer.
• Brew Temperature = 204°F
• Brew Volume = Set to dispensing vessel requirements
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 flow rate of ½ gpm (1 gpm preferred flow 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 filter to the brewer.
NOTE: A water filtration 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 filter. For our full line of filters,
please log on to www.wilburcurtis.com.
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.
2. In some areas an approved backflow prevention device may be required between the brewer
and the water supply.
3. Water pipe connections and fixtures directly connected to a potable water supply shall be sized,
installed and maintained in accordance with federal, state, and local codes.
1. A 1/4" Flare has been supplied for water line connection. Use tubing sized sufficiently to provide ½ GPM
(preferred flow 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 fill. 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). This is indicated
when READY-TO-BREW is displayed on the screen.
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 operation.
