SETUP STEPSSETUP STEPS
SETUP STEPSSETUP STEPS
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” NPT x 1/4” Flare elbow has been supplied for water line connection. Use tubing sized sufficiently to provide a
minimum of 1.0 GPM.
2. To hookup the InterLock grinder, Locate the jack labeled “Class 2 Wiring Only” on brewer and grinder. Connect the two with
the cable plug.
3. Connect the unit to an appropriate electrical power circuit.
4. 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.
5. The heating tank will require 20 to 30 minutes to reach operating temperature (200°F) as indicated by the READY-TO-
BREW indicator.
6. Prior to brewing, dispense 12 ounces of hot water through the hot water faucet.
7. Brew a cycle of at least 12 ounces, to purge the water lines of any air that may be trapped after filling.
The National Sanitation Foundation 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.
