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 container of at least 4 gallons capacity under the funnel.
3. Connect the brewer to the power source.
4. Place the "ON/OFF" switch in the "ON" position. Tank will start to fill automatically.
5. Water will flow into the tank and dispense for approximately eighteen minutes, then cycle will stop.
6. Heater circuit will activate automatically.
7. Wait approximately fifty minutes for the water in the tank to heat to the proper temperature.  The ready light

will be activated when the brewer reaches the proper temperature.

8. Press the START switch to begin a brew cycle. Once water comes out of the sprayhead, place the "ON/OFF"

switch in the "OFF" position. This will dispense the expansion water in the tank.

9. Empty contents of the container through the faucet.
10. Place the "ON/OFF" switch in the "ON" position then momentarily press and release the "START" switch.
11. Allow the cycle to finish and measure the amount of water in the container. It should be 512 ounces 

±

2. Refer

to the adjustments section of this manual should the volume need to be increased or decreased.

The brewer is now ready for use in accordance with the Tea Brewing instructions.

OPERATING CONTROLS

A.

ON/OFF Switch

ON - 

Placing the switch in the "ON" position allows the start switch to activate a timed brew cycle for four gallons

of tea.

OFF - 

Placing the switch in the "OFF" position stops the brew cycle.  Stopping a brew cycle after it has been started

will not stop the flow of water into the funnel until the tank syphons down to its proper level.  

The switch should

always be placed in this position after a brew cycle and whenever the brewer is unattended.

B.

Start Switch

Starts a brew cycle when the ON/OFF switch is in the "ON" position.

C.

Ready Indicator

This indicator glows when preselected brew water temperature has been achieved. It is also used for diagnostic
testing of brewer.

D.

Sanitize Switch

Starts a sanitize cycle when pressed and released.  This functions when the ON/OFF switch is in the "ON" position.

E.
