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. Place the heater switch at the rear of the brewer in the “OFF” lower position and connect the brewer to the
power source.
4. Fill the tank with water as directed:
4A. Model C
Pour three pitchers of tap water into the screened area on top of the brewer. Allow approximately two
minutes between pitchers for water to flow into the tank. While the third pitcher of water is entering the
tank, the tank will fill to capacity and the excess will flow from the sprayhead, out of the funnel, and into the
dispenser.
4B. Models CT, CTF, CWT, CWTA, CWTB, CWTF, CWTFA, CWTFB, SINGLE CW & SINGLE CWF
Connect the brewer to the power source, place the "ON/OFF" switch in the "ON" upper position, and momen-
tarily press and release the start switch. Water will begin flowing into the tank. When water stops flowing
into the tank, initiate a second and a third brew cycle. During the third brew cycle the tank will fill to its
capacity and the excess will flow from the sprayhead, out of the funnel, and into the dispenser.
5. When the flow of water from the funnel stops, place the heater switch at the rear of the brewer in the “ON”
upper position and wait approximately twenty minutes for the water in the tank to heat to the proper tem-
perature. Some water will drip from the funnel during this time; this is due to expansion and should not
occur thereafter.
6. Empty the dispenser and initiate another brew cycle as directed:
6A. Model C
Pour one pitcher of tap water into the screened area on top of the brewer.
6B. Models CT, CTF, CWT, CWTA, CWTB, CWTF, CWTFA, CWTFB, SINGLE CW & SINGLE CWF
Place the "ON/OFF" switch in the "ON" upper position, and on models SINGLE CW and SINGLE CWF place
the batch selector switch in the "1 GAL" position. Momentarily press and release the start switch.
7. 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.
8. Empty the dispenser; 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 for all models except SINGLE CW and SINGLE CWF should be 128 ounces.
9. Models SINGLE CW and SINGLE CWF only, place the batch selector switch in the "1/2 GAL" 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.
10. If water volumes are not correct, adjust the brew timer as required. See Adjusting Brew Volumes. Allow
the water to reheat. Start, and measure another brew cycle.
11. Repeat step 10 until correct water volume is achieved.
NOTE: For all Twins, repeat steps 1 through 10 for the other side.
12. The brewer is now ready for use in accordance with the coffee brewing instructions.
ADJUSTING BREW VOLUMES
NOTE: Check that the brewer is connected to water supply, the tank is properly filled, and a funnel and server or
decanter are in place, prior to setting or modifying batch sizes.
1. Modifying batch sizes. To modify a batch volume, first check that the SET/LOCK switch is in the “SET” posi-
tion on the circuit board. If the brewer has a batch selector switch, position it to the size to be changed.
0 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
