Sanitation Requirements
Your Curtis G3 System is Factory Pre-Set and Ready to Go… Right from the Carton.
Following are the Factory Settings for your interLock Coffee Brewing Systems:
• Brew Temperature = 200°F • Water Bypass = On LARGE & MEDIUM brew only
• Brew Volume = Large set to vessel requirements. • Energy Save Mode = Off
System Requirements:
• Water Source 20 – 90 PSI (Minimum Flow Rate of 1 GPM)
• Electrical: See attached schematic for standard model or visit www.wilburcurtis.com for your model.
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.
1. A 3/8”Flare x 3/8” Male pipe elbow is supplied with the brewer for water line connection. Use tubing sized sufficiently to provide a
minimum of 1.0 GPM.
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 G3 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), indicated when READY TO BREW is displayed
on the LCD screen.
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.
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.
