ALPHA DIGITAL
The Alpha Digital series of automatic coffee brewers require installation to be in compliance
with all local water and electrical power codes. The Alpha is designed to brew 12 cups at a
time. The Alpha 3D, 3DL and 3DR have three warmer plates that allow up to three decanters to
be kept at serving temperature. The hot water faucet lets you draw hot water for tea, instant
soups, chocolate drinks or cup meals - even during the brew cycle.

CAUTION DO NOT connect this brewer to hot water. Inlet valve not rated for hot water.
The National Sanitation Foundation (NSF), requires the following water hookup:
1. A quick disconnect water connection or enough extra coiled tubing (at least 2x the depth of the
unit) so that the machine can be moved for cleaning underneath.
2. An approved flow back prevention device, such as a double check valve to be installed between
the machine and the water supply.
Alpha decanter brewers are shipped with the power cord connected inside the machine. The
power cord ends with an electric plug having two flat blades with a round grounding pin, 120VAC
current and 20 amp rating. Some units are rated for 220 volts. Check the serial plate on the side
of the machine to make sure of the electrical requirements for your unit.
THIS EQUIPMENT IS TO BE INSTALLED TO COMPLY WITH THE APPLICABLE FEDERAL, STATE, OR LOCAL PLUMBING CODES HAVING JURISDICTION.
The Alpha unit should be located on a solid counter top. The counter top should be level. Connect
the water line from the water filter to the unit using ¼" copper tubing with a flare fitting at the end.
Some type of water strainer must be used to maintain a trouble-free operation. In areas with ex-
tremely hard water, we suggest that an Everpure QC7-MH water filter be installed. Water filters may
be ordered from the Wilbur Curtis Company. For customer service call (800) 421-6150.
