Settings and Adjustments
Caution! Always unplug or disconnect power to the brewer before changing any settings or adjustments.
All settings and adjustments, except for the optional green tea faucet, are made on the control board, which is
accessible inside the back of the unit. (See the control board diagram.)
Dispense System
The TBS-21H features a system which dispenses factory calibrated amounts of hot and cold water completely
before refilling the tanks. The amount of water (0.6 gallons hot, 2.4 gallons cold) is not adjustable. The water
tanks will not refill until the brew cycle is finished and the dispense valves have closed.
Brew Time (bottom dial)
The brew time is adjustable from 2 to 12 minutes and is factory set at 12 minutes.
The brew time always defaults to the nearest full minute on the dial.
The brew time must be set long enough to dispense the full volume of water.
See the next section, Pulse Feature, for a full explanation.
Pulse Feature (top dial)
The pulse feature allows the spray of water over the tea to cycle on and off throughout
the brew cycle. The setting is made on the top dial on the control board,
labeled “ON TIME”. The total pulse cycle is 30 seconds in length.
Examples:
1.) The factory setting, 10 seconds, will give 10 seconds of spray over
followed by a 20 second pause.
2.) A setting of 15 seconds will give 15 seconds of spray over followed by a
15 second pause.
3.) A pulse setting of 30, the maximum, will give a constant spray of water
throughout the brew cycle. In other words, no pulse at all.
The Pulse and Brew settings must be synchronized so that the dispense valve is open
long enough to dispense all of the brew water.
Use the following chart to determine the proper settings.

Regarding clarity…
The clarity of the final product may be improved by allowing the hot tea to sit for a few
minutes before it is diluted with cold water. This is achieved by setting the brew time higher than the minimum
necessary to dispense all of the water. The recommended settings listed include extra time for clarification.
If these settings do not produce enough tea to satisfy demand, you may reduce the brew time to increase
production, which may result in a cloudier appearing product. Do not reduce the brew time setting below the
minimum settings shown. Experimentation will be necessary to determine the best settings for your particular
type of tea.
