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 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.
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) 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.
BREWING INSTRUCTIONS
1. Brewer should be ON (Conrm at rear toggle switch, then press ON/OFF button) and Ready-to-Brew displayed.
2. Place lter in brew basket.
Pour leaf tea into basket.
3. Slide brew cone into brew
rails. Place tea container
under brew cone.
4. Press the BREW button to
brew tea.

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 airpots and tea containers will maintain the highest quality coffee and 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.
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. Wear rubber gloves for protection.
B. Immerse in commercial Bar Tabs/Sani-Tabs sanitizing solution The solution must be warm (75°F.)
Let the parts soak for at least one minute.
8. Thoroughly rinse parts with hot water. 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
10
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: Disconnect electrical power before removing access panels.
CAUTION: This procedure involves working with hot water and hot surfaces.
1. Unplug the power cord and shut off the water line.
2. Remove the top cover of the unit. Locate the top of the tank and
remove the cover.
3. Drain the tank to a level about 3” below the tip of the probe.
4. Allow some time for the probe to cool before working on the brewer.
5. Clean the tip of the probe using a Scotch-Brite
6. If a residual white layer is still visible on the probe, remove the probe
and soak it in vinegar or a scale removing chemical. Repeat this step
until the white layer is removed.
