Sanitation Requirements
Your Curtis Combo Brewer is Factory Pre-Set and Ready to Go... Right out of the Box.
Following are the Factory Settings for your Coffee/Tea Brewing System:
• 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 flow rate of ½ gpm (1 gpm preferred flow rate).
• Electrical: See attached schematic for standard model or visit www.wilburcurtis.com for your model.
Equipment to be installed to comply with applicable federal, state, or local plumbing/electrical codes having jurisdiction.
SETUP STEPS
The unit should be level (left to right and front to back) and located on a solid 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 the unit.
2. This equipment is to be installed with adequate back flow protection to comply with applicable federal, state and local codes..
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 a minimum of ½ gpm (1 gpm is
preferred).
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 the G3/Gold Cup Series there is no danger of element
burnout due to an unfilled heating 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 TEA brew cycle first, before running a coffee brew cycle to purge water lines and valves of air. Five
seconds of pulsing dilution water at the beginning of each TEA brew cycle is normal pre-programmed operating behavior.
BREWING INSTRUCTIONS – COFFEE
1. Ready-to-Brew should be displayed on the UCM screen.
2. Make sure that the folding airpot deck is in the proper position to accommodate your airpot. Place a clean, empty airpot on the deck.
3. Place a new paper filter into the brew cone.

    Rough-In Drawing Cleaning the Brewer Regular cleaning and preventive maintenance is essential to keep your coffee brewer looking and working like new. CAUTION – Do not use cleansers, bleach liquids, powders or any other substance containing chlorine. These products promote corro- sion and will pit the stainless steel. USE OF THESE PRODUCTS WILL VOID THE WARRANTY. 1. Wipe exterior surfaces with a moist cloth, removing spills and debris. 2. Slide the brew cone out and clean it. Clean the spray head area with a moist clean cloth. 3. Rinse and dry the brew cone. 4. Rub a stainless steel polish on the outside surfaces to protect the brewer. Cleaning the Tea Containers 1. 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. 2. 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. 3. After the cleaning, place the parts (sprayhead, brew cone and basket and faucet parts) rinse the parts in hot water to remove traces of detergent.

Wipe the exterior surfaces with a sponge moistened with the detergent solution, removing water spots and coffee. 3. Remove and clean the syphon tube/funnel with a detergent solution. 3. Clean inside the airpots with a sponge brush soaked in detergent solution. 4.
