1. Attach the flare fitting from the short piece of tubing on the strainer

PLUMBING REQUIREMENTS (cont.)
INITIAL SET-UP
CAUTION - The brewer must be disconnected from the power source throughout the initial set-up, except when
specified in the instructions.
1. Insert an empty funnel into the funnel rails.
2. Place an empty dispenser under the funnel.
3. Connect the brewer to the power source, place the "ON/OFF" switch in the "ON" upper position, and momentarily
press and release the start switch. Water will begin flowing into the tank. When water stops flowing into the
tank, initiate a second, third and a fourth brew cycle. During the fourth brew cycle the tank will fill to its capacity
and the excess water will flow from the sprayhead, out of the funnel, and into the dispenser.
4. When the flow of water from the funnel stops, wait approximately twenty minutes for the water in the tank to
heat to the proper temperature. Some water will drip from the funnel during this time; this is due to expansion
and should not occur thereafter.
5. Empty the dispenser and initiate another brew cycle.
6. Place the "ON/OFF" switch in the lower "OFF" position after water has stopped flowing from the funnel, and let
the water in the tank reheat to the proper temperature.
7. Place the "ON/OFF" switch in the "ON" upper position, and momentarily press and release the start switch. Check
the water volume in the dispenser after water has stopped flowing from the funnel. It should be 64 ounces.
8. If not, adjust the brew timer as required. See
Adjusting Brew Volumes.
Allow the water to reheat, start, and
measure another brew cycle.
9. Repeat step 8 until 64 oz water volume is achieved.
10. The brewer is now ready for use in accordance with the coffee brewing instructions on the next page.
ADJUSTING BREW VOLUMES
CAUTION - Disconnect the power source from the brewer prior to the removal of any panel for the replacement
or adjustment of any component.
NOTE: Prior to setting or modifying batch sizes, check that the brewer is connected to water supply, the tank is
properly filled, and a funnel and server are in place.
1. Modifying batch sizes. To modify a batch volume, first check that the SET/LOCK switch is in the "SET"
position on the circuit board.
To increase a batch size. Press and hold the START or BREW switch until three clicks are heard. Release the
switch (Failure to release the switch within two seconds after the third click causes the volume setting to be
aborted and previous volume setting will remain in memory) and press it again one or more times. Each time
the switch is pressed, two seconds are added to the brew time period. Allow the brew cycle to finish in order
to verify that the desired volume has been achieved.
