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 (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 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.
CAUTION: DO NOT
connect the unit to hot
water. The inlet valve is
not rated for hot water.
IMPORTANT:
After setup, run a FULL
brewcycle. Place a tea
container to catch both hot water
from the brewcone and dilution water
from spout on the front cover.

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 backow prevention device may be required between the brewer
and the water supply.
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.
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). 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.

TEA TIPS
WARNING DO NOT
refrigerate unused
tea overnight for later
consumption.
CLEANING
IMPORTANT: If the
brew cone comes with
a screen; clean the
screen to maintain the
tea ow. Neglecting this screen will
eventually cause the brewcone to
overow, spilling hot liquid over the
unit.
CAUTION: DO NOT
use undiluted bleach or
chlorine.
1. Store tea bags in a dark, cool and dry place away from strong odors and moisture. Do not refrigerate.
2. Never hold nished brewed tea for more than eight hours at room temperature. Discard any unused
tea after eight hours
3. Brew only enough tea that you reasonably expect to serve within a few hours.
4. To protect tea avor and to avoid bacterial contamination and growth, clean and sanitize tea brewing,
storage and dispensing equipment at least once a day.
Regular cleaning of your tea containers will maintain the highest quality iced tea your equipment is
capable of producing. A proper cleaning is essential in preserving the appearance of the brewer.
1. Turn off the tea brewer at the ON/OFF button on the front control panel.
2. Wipe exterior surfaces with a damp cloth, removing spills and debris.
3. Slide the brewcone out and clean it. Thoroughly soap the sprayhead area with a mild detergent solution.
4. Wash the brewcone and wire brew basket, if applicable. Use a soft bristled brush for hard to clean
areas. Wash both parts with a detergent solution or put these parts through a dishwasher.
5. Wash the tea container and top cover. Use a detergent solution and a soft bristled brush to clean inside
the container. Wipe the exterior surfaces with a sponge and detergent solution. Rinse thoroughly.
6. Clean the faucet assembly. Unscrew the handle assembly from the faucet and remove. Clean the
faucet shank with a gage glass brush (circular bristle) by pushing the brush through the shank. Using
the same brush clean the faucet body inlet and outlet. Clean the faucet cap and silicone seat cup.
Thoroughly rinse parts with hot water.
7. After the cleaning, place the parts (sprayhead, brewcone and basket and faucet parts) into a sink to be
sanitized.
To sanitize the disassembled parts:
A. Use a clean container to submerge all parts.
B. Immerse in commercial Bar Tabs/Sani-Tabs sanitizing solution The solution must be warm (75°F.)
Let the parts soak for one minute.
8. Air dry, all parts that were sanitized.
9. After cleaning, sanitizing and drying, assemble any parts taken from the tea container.
10. Clean out airpots with a sponge brush and a mild detergent solution. To remove mineral deposits, ll
liner with vinegar and allow to soak.
LIQUID LEVEL
PROBE
12
Cleaning intervals for the probe are to be determined by the user or the service tech, based on water condi-
tions. The use of water lters, or the type of water lter that is being used can impact the service interval.
Intervals can be from one month to several years, however, replacing rather than cleaning the probe is
preferable.
WARNING: Electric shock hazard. Disconnect electrical power before removing access panels.
CAUTION: Scalding and Burn hazard. Hot water and hot surfaces. Allow unit to cool before working.
1. Unplug the power cord and shut off the water line.
2. Remove the top cover of the tea brewer. Locate the heating tank
and remove the top cover.
3. Drain the tank to a level about 3” below the tip of the probe.
4. Allow some time for the heating tank and liquid level probe to cool
down before proceeding.
5. Clean the tip of the probe using a Scotch-Brite
6. If a white residue is still visible on the probe, remove the probe and soak it in vinegar or a scale
removing chemical. Repeat this step until the probe is clean.

Tank Temperature Check
Turn on brewer at the control panel ON/OFF button. Press and hold
the button (arrow) for 5 seconds. The water temperature in the heating
tank will be displayed on the screen. Press to exit.
Error Message
With G3/Gold Cup Series brewers, there are three error messages that can appear on the screen to advise the user of a malfunction. If one of
these error messages appear, the brewer will lock up and stop functioning until the error is corrected.
An error message will occur under the following conditions:
1. Water level ll error or overow. This error message occurs when the inlet valve solenoid has been on for more
than 10 minutes. This error message also occurs when the valve is relling the tank during a brew cycle for
more than 1½ minutes.
2. Water temperature control system error. An open probe or a break in the temperature control circuit is detected.
The screen may display a phone number to call for service. After the malfunction is corrected, the error message
must be cleared. To reset the control panel and return to normal operation, press for 5 seconds.
