WARNING:
- Read and follow installation / setup instructions before plugging or wiring in machine to electrical
circuit. Warranty will be void if machine is connected to any voltage other than that specified on the name plate.
Plumber's Installation Instructions
1) Plumb brewer in to water supply using 1/4 inch copper tubing. Flush water line before installing brewer to
remove sediment. Brewer should be connected to COLD WATER LINE for best operation.
2) Water pressure should be at least 20 PSI. For less than a 25 ft run, use 1/4" tubing and connect to 1/2" or larger
water line. The inlet water fitting on the back of the brewer is a 1/4" flare fitting.
3) If installed with saddle valve, the valve should have a minimum of 1/8" port hole for up to 25 ft run, and 5/16" port
hole for over 25 ft runs.
4) Manufacturer strongly recommends use of a water filter to reduce scale and sediment as well as to provide for a
better tasting beverage. Connect water line from filter to the flow control attached to the flared fitting extending
from the back of the brewer. Manufacturer recommends connecting to copper tubing.
5) Check for leaks.
Initial Setup Instructions
Ensure power switch on right rear of unit is in the off position. Plug or wire brewer to the appropriate voltage circuit
as indicated on the serial tag. Turn power switch to the on position. Brewer tank will begin to fill. Once the tank is
full the brewer will begin to heat. Ready light will come on to indicate tank has finished heating.
CAUTION: The water faucet will dispense hot water anytime the handle is pulled.
Programming - 121753 firmware
The 20:1 Brewer may be ordered as a standard coffee brewer or as a "combo" brewer capable of brewing both
coffee and iced tea beverages. The combo brewer incorporates a 2
mix with the brewed tea concentrate. Brewers with r2 and higher firmware are also now available with an alternate
mechanical heater relay as an option to the solid state relay. The new main control board (part no 121753) includes
a couple of additional programming steps compared to previous control versions (part no 100729) to accommodate
these options. The tables on the next couple of pages have the new programming steps highlighted as an aid to
those familiar with the previous programming procedures.
The brewer has two program modes, service mode and user mode. The service mode is used to establish basic
operating parameters of the unit while the user mode allows the three buttons to be programmed for brewing into
various containers or for varying beverage volumes. Programming mode is initiated as outlined below. The following
pages will outline the various steps as displayed by the programming "screens". The screens will loop continuously
until exiting the mode.
