Sanitation Requirements
Your Curtis ADS System is Factory Pre-Set and Ready to Go… Right from the Carton.
Following are the Factory Settings for your ALPHA™ GT Coffee Brewing Systems:
•Brew Temperature = 200°F
•Brew Volume = Set to dispensing vessel requirements (60 oz)
•Warmer Setting on HIGH with Quality Timer OFF
Generally there will never be a reason to change your G3 programming. 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. Must have a minimum flow rate of ½ GPM (preferred flow rate is 1 gpm).
• 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), located on a solid counter top. Connect a water line from the water filter to the brewer. NOTE: Some type of water filtration device must be used to maintain a trouble-free operation. (In areas with extremely hard water, we suggest that a sedimentary and taste & odor filter 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 backflow prevention device may be required between the brewer and the water supply.
1.A 3/8” NPT x 1/4” Flare elbow has been supplied for water line connection. Use tubing sized sufficiently to provide a minimum of
½gallon per minute.
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 elements will energize automatically. With ADS Systems 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 (200°F) as indicated by READY-TO-BREW displayed on the LED.
5.Prior to brewing, dispense 12 ounces of hot water through the hot water faucet.
6.Brew a cycle of at least 12 ounces, to purge the water lines of any air that may be trapped after filling.
BREWING INSTRUCTIONS
1.Brewer should be ON (Confirm at rear toggle switch, then press ON/OFF button). Ready-to-Brew should be displayed.
2.Place empty decanter (not included with Alpha brewer) on warmer plate.

High-Yield coffees typically extract better with the C pulse setting. Of course, any of the A, B or C settings may be used to suit your taste profile. There are two additional settings (D and E) that allow you to manually set the ON TIME pulses and OFF TIME.
