20:1 INSTALLATION / SETUP INSTRUCTIONS

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

water valve to deliver the cold water dilution to

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.

Man PN 121751 Rev 20170617

Service Mode is entered by holding any two of the buttons on the face of the machine while powering up the brewer.

The brewer firmware revision number is displayed for a couple of seconds when entering this mode. The table below

list the items that may be programmed along with available values or settings. Use the center brew button to

advance through the items and the left and right button to decrement or increment the values/selection respectively.

These items are programmed at the factory and will typically not need adjustment. For coffee only brewers (no 2

valve) ignore the dilution calibration and cold calibration volume. Use the center button to advance through those

items.

Pump Calibration:

Pump calibration is necessary when the pump speed is changed or if the brewer is delivering substantially more or

less beverage than what it has been programmed for in the user mode. Pump speed may be adjusted up or down if

required to deliver water at a faster or slower rate to meet a specific beverage taste profile. Calibration tells the

brewer control how much hot water is delivered within a specific time frame so it can adjust the time required to run

to deliver the desired brew volumes.

Ensure the brew basket is in place. Place a suitably graduated container in place below the brew basket to capture

and measure the water delivered. To calibrate, enter the service mode as noted above and advance to the “CAL”

screen. Press either the left or right brew button and water delivery will begin. If the brewer has not reached

operating temperature, it will finish heating before automatically starting. The pump will cycle on and off for

approximately 2 minutes at which time the currently programmed volume is displayed. Use the left and right button

to decrement or increment the value to the measured value. For better accuracy, you may want to measure a couple

of cycles and average the measured values. At the least, the system should be primed before calibration by allowing

a partial brew cycle to run (10-15 secs).

Note: User mode will be entered automatically when exiting the service mode if calibration values have been

changed.

Man PN 121751 Rev 20170617

Service Data consist of the tank temperature as measured at two points in the tank and an indication as to which

probe(s) are making contact with the water. To view data, enter the service mode as noted above and advance to

the “Srv” screen. Use the left or right button to enter service data mode. Use the center button to advance through

the data. The table below list the data that is displayed.

* The 3 dashes indicate that the temperature value reported by the thermistor is outside the display range, 100-215F.

This could be because the tank is cold or because the thermistor is out of calibration. If the tank temperature is

within the noted range, the thermistor is defective and should be replaced.

User Mode is entered by holding any one of the buttons on the face of the machine while powering up the brewer.

Note that the user mode is also automatically entered whenever the calibration volume setting is changed. The

beverage volumes, brew time, and visa-brew time can be programmed for each of the three buttons on the face of

the brewer. The brew volume may all be run through the basket or a portion of the total volume may be added to the

brewed concentrate as cold water dilution. The brewer will determine the minimum brew time possible based on

pump speed and calibration values as outlined previously. This time is set as the default whenever calibration values

are changed. The brew time can be extended to lengthen the water delivery time to meet a specific beverage taste

profile. For coffee only machines, brew total and brew concentrate should match. The table below list the data

displayed and values available.

OPERATION INSTRUCTIONS

Coffee/Tea Preparation Procedures

1) Place filter into brew basket.

2) Put the proper amount of coffee or tea into the filter. Filter not required for filter pack coffee/tea.

3) Slide the brew basket into holder.

4) Place the appropriate empty decanter into position below the brew basket. For airpots first open lid and remove

pump stem unless of a brew through design. For other dispensers remove the lid unless it is a brew through

design.

5) Press the appropriate brew start switch. Note: a brew cycle may be initiated even if the heating light is on. The

brewer features an autoarm circuit which will flash the heating light indicating that the brewer is heating and will

begin to brew immediately after the heating cycle is complete. To over ride autoarm, hold in brew button until

cycle starts (5 seconds).

6) Do not remove decanter. Brew cycle may be canceled by depressing any brew button or the cancel switch on

the front control panel.

7) Hot water will be delivered through the sprayhead. This distributes the hot water evenly over the coffee bed

within the brew basket. The coffee brew will drain from the brew basket into the decanter below.

8) The Brewing light should continue to flash until all the liquid has finished flowing from the brew basket. Do not

remove decanter until the brewing process has stopped and all liquid has stopped flowing from the brewbasket.

9) The resultant coffee brew should be crystal clear and have the desired properties attainable through excellent

extraction.

10) To clean brew basket simply remove from brew rails and dump filter into waste basket. The brewing process, as

described above, can now be started again.

Error Messages

This brewer incorporates a number of self diagnostic test that are routinely run. If a fault condition should occur the

unit will display an error number as outlined below. All errors may be reset by powering unit off and then back on.

Errors E1 and E2 are auto-resetable and will clear themselves if the condition that caused them goes away. E3 will

disable the heater but will allow a brew cycle to complete. The brewer will try to heat again when a brew cycle is

started. E4 and E-A must have power to unit cycled to clear them. E5 will force brewer to use its default settings for
