Introduction
Model TBS-21H 3 Gallon Iced Tea Brewer
The TBS-21H is the most innovative Iced Tea Brewer ever introduced. The exclusive PulseBrew feature gently
showers the tea leaves with hot water for several seconds, then pauses while the water drains through. This
alternating spray and pause cycle repeats throughout the brew cycle. PulseBrew is adjustable, and can be set
for a continuous spray (no pulse) if desired.
Conventional tea brewers steep the tea leaves, submerging them in a bath of hot water throughout the brew
cycle. The TBS-21H allows most of the water to drain out of the tea leaves between pulse cycles. This allows
oxygen to contact the tea leaves throughout the brewing process for the best flavor extraction available.
The cold water dilution ratio is also different than most tea brewers. After brewing 0.6 gallons (77 oz.) of
concentrated hot tea, the TBS-21H automatically adds 2.4 gallons (307 oz.) of cold water. The result is a 1:4
ratio, the best for tea flavor extraction with PulseBrew’s unique brewing style. Other tea brewers typically use a
1:2 ratio (one third hot / two thirds cold).
If you have any questions about your new tea brewer, please call FETCO at [phone], or visit our web site

Keys To A Successful Installation
FETCO brewers are rugged and reliable machines that will provide many years of service. However, if not
installed correctly by qualified personnel, the brewer will not operate properly and damage to the brewer may
result. Damages resulting from improper installation are not covered by the warranty.
Here are the key points to consider before installation:
General: Utilize a qualified beverage equipment service technician for installation.
Place the brewer on a level surface.
Do not adjust the thermostat setting unless absolutely necessary. It is set at the factory for optimum
performance- 205°F. It should only be lowered at high altitude installations.
Plumbing: This equipment is to be installed to comply with the applicable federal, state, or local plumbing codes.
The water line must be flushed thoroughly prior to connecting it to the brewer to prevent debris from
contaminating the machine.
A taste and odor filter is highly recommended for this and all beverage equipment
Verify that the water line will provide at least 2 gallons per minute before connecting it to the brewer.
Electrical: 120 volt units are supplied with appropriate cords and plugs for 15 amp or 20 amp service.
Dual voltage units (120/208-240VAC) are not supplied with a cord or plug. The terminals must be wired as
follows: L-1: 120 VAC L-2: neutral (white) L-3: 120 VAC ground (green)
Both neutral (white) and ground (green) must be provided.
The electrical drawing is located inside the rear cover of the brewer.

Installation Check List
The installation must comply with applicable federal, state, and local codes having jurisdiction at your location.
Check with your local inspectors to determine what codes will apply to the installation and operation of FETCO
products.
1. Review the Dimensional Drawings and the Operating Procedures for the unit you are installing. Verify
the brewer will fit in the space intended for it. Verify that the counter or table will support the weight of
the brewer and dispensers when filled and that the surface is level.
2. Verify that the actual voltage at the electrical service connection is compatible with the specifications on
the brewer’s serial number plate. Make sure the electrical service includes neutral. Ensure at this time
that the circuit breaker to the brewer and the power switch on the brewer are in the off position.
3. Remove the white plastic protective coating from the brewer body.
4. The thermostat, timer, and the water tank fill level are pre-set at the factory. There is no need to turn
off the heaters during the installation process. The heaters are disabled by the liquid level
control circuit on the main board until water is sensed. The heating process will start automatically
when the tank has filled with water.
5. Remove the top and rear panel to inspect for leaks, loose wires, etc., and for adjustments.
6. Water connection:
• Water inlet is a 3/8 inch male flare fitting
• We discourage the use of softened water. Softened water will give poor brew performance in any
drip tea system using a paper filter.
• Install a water shut off valve near the brewer to facilitate service. If an in-line water filter is used, it
should be installed after the water shut off valve and in a position to facilitate filter replacement.
• Flush the water supply line and filter before connecting it to the brewer.
• Verify that the water line will provide at least 2 gallons per minute, and that the water pressure is
between 20 and 75 psig.
• Use a wrench on the factory fitting when connecting the incoming water line. This will reduce stress
on the internal connections and reduce the possibility of leaks developing after the install has been
completed.
7. Power connection:
• A fused disconnect switch or circuit breaker on the incoming power line must be conveniently
located near the brewer, and its location and markings known to the operators.
• All brewers require neutral. Damage to the brewer may result if neutral is not present.
• The body of the brewer must be grounded to a suitable building ground. A ground lug is provided in
the brewer on the floor of the chassis. Use suitable gauge copper wire for grounding.
• Electrical connections must be secured in-place within the unit to meet national and local standards.
8. Turn on the incoming water supply line and inspect both inside and outside of the brewer for leaks in all
fittings and tubes.
9. Plug in brewer and turn on the incoming power
10. Turn on the brewer with the power switch.
• Within 6 seconds, the internal tanks will begin filling until the water is sensed by the water level
probe.
• The heaters will be disabled by the L.L.C. circuits on the main board until water is sensed by the
water probe at the top of the tank.

5
On initial startup, from dry tank conditions, the green "READY" will flash 3 minutes after turning unit on, indicating
a fault (low water level). Turn the power switch off and back on to reset this. Repeat one additional time if
necessary
11. Brew one dispenser (water only) to confirm proper fill levels.
• The brewer is factory set to deliver a total of 3.0 gallons to the dispenser.
• Tea leaves retain water after brewing, therefore your brew level will be reduced proportionally to the
amount of tea used.
• Review the entire operating procedures with whoever will be using the brewer. Pay particular
attention to the following areas.
• Don't remove the brew basket until it has stopped dripping.
• Don't remove the spray plate until it has cooled from the brewing operation. It may still be hot, and
hot brew water may be retained behind it.
• Make sure the dispenser is empty before brewing into it.
• Show the location and operation of the water shut off valve as well as the circuit breaker for the
brewer.
• Never unplug the tea brewer (or any high wattage equipment) while it is operating. Push the power
switch to the off position first. The resulting electrical pulse may cause a burn or shock hazard, or
damage the computer operating circuits on the control board.
• Steam from the tank will form condensation in the vent tube. This condensation will drip into and then
out of the brew basket. Up to 1/4 cup discharging overnight is possible. Place an appropriate
container under the brew basket when not in use.
The brewer will be ready for operation as soon as the ready light comes on to signify that the water tank is up to
temperature.
Depending on the cost of electricity in your area, very little savings may be had by turning the brewer off between
shifts. The water tank is well insulated and may actually use less electricity to keep the tank hot, than re-heating
the tank from a cold condition. Leaving the brewer in the on position will also avoid delays at the beginning of
shifts for the brewer to reach operating temperature.

Operating Procedures
Operating ProceduresOperating Procedures
Operating Procedures
1. Turn brewer power switch to the on position
• The power switch will illuminate to indicate that the brewer has power and is operational.
• When the ready light illuminates, the brewer is fully up to temperature. The amount of time
required to gain full operating temperature will vary depending on the electrical configuration that
was ordered, and the temperature of the incoming water.
2. Prepare the brew basket.
• Place a paper filter in the brew basket. Pour the appropriate amount of tea into the paper filter, and
distribute it evenly. The amount of tea used will depend on your personal tastes and the
recommendation of your supplier.
• Slide the brew basket into place.
3. Place the dispenser in position under the brew basket.
• Make sure the dispenser is empty. Overflowing may result if it is not completely empty when the
brew cycle begins.
• Ensure that the dilution spout is inserted into the back of the dispenser
• Ensure that the dispenser is pushed all the way in, so that the dispenser body is pressing the
sensing switch.
Optional Setting: Brew Temperature Protection
The TBS-21H is factory set so that it cannot brew unless the water is at the proper temperature. If a
brew cycle is started without the ready light on, no water will be dispensed and the brew light will begin
flashing. Once the water heats to the proper temperature, the brew cycle will begin normally. See the
Settings & Adjustments section for instructions on disabling this feature.
4. Start the brew cycle.
• Start a brew cycle by pressing the start switch.
• The brew light will illuminate during the brew cycle. At the end of the brew cycle, the brew light will
flash for 4 minutes, indicating that hot tea is still dripping from the brew basket and that cold water is
flowing into the back of the dispenser through the dilution tube. Do not move the dispenser until the
brew light has stopped flashing.
• The factory settings include a time delay between the brew cycle and dilution cycle to allow for
clarification (See page 8). As a result, the brew light will continue to blink for a few minutes after tea
has stopped dripping, before the dilution cycle begins.
• CAUTION! Do not remove the brew basket until dripping from the bottom of the brew basket has
stopped. Carefully remove the brew basket while inspecting the inside of the basket for hot tea that
may have been trapped or has not finished draining.
• To interrupt the brew cycle at any time, press the stop switch. This will reset all functions.
Hot Water Faucets
The red and green hot water faucets must not be used during the brew cycle. Using the faucets will
reduce the amount of water for brewing, resulting in a short batch.
Cleaning
CleaningCleaning
Cleaning
Brewer: At the end of each day, wipe the underside of the spray plate. The spray plate should be removed and
cleaned periodically to remove hard water deposits. In areas with extremely hard water, it may be necessary to
do this weekly. Monthly cleaning may be sufficient in areas with average water conditions.
Dispensers: The dispensers are dishwasher safe, and should be cleaned daily. If cleaned manually, use
detergent and a soft brush or sponge. Do not use wire brushes or abrasive pads. To prevent deposits from
forming, do not allow tea to sit inside the dispenser overnight.

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.
(Standard factory settings shown in bold.)

30 (No pulse) 7 2
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.

Temperature (center dial)
The brew water temperature is adjustable from 190°F to 205°F and is factory set at 205°F. The adjustment is
made on the center dial of the control board. Adjustment should only be necessary at high altitudes to prevent
boiling. Check the temperature by holding a thermometer in the stream of water flowing out of the hot water
faucet with the red handle.
Brew Temperature Protection
When this feature is enabled, a brew cycle cannot begin unless the water is at the proper
temperature. If a brew cycle is started without the ready light on, no water will be dispensed and
the brew light will begin flashing. Once the water heats to the proper temperature, the brew cycle
will begin normally.
The brewer is factory set with this feature enabled. To disable it, locate the yellow wire near the
lower right side of the control board. Move the wire from the terminal labeled START 1 to the
terminal labeled START 2.
Jumper Settings
The control board is used on a variety of different brewer models. In order to function properly
in the TBS-21H, Jumper #1 must be in the closed position, as shown below:
Jumper 1 in closed position.
Correct Configuration
Jumper 1 in open position.
Incorrect Configuration
Jumper # 2 & 3 are not used for the TBS-21H.
Green Tea Faucet (optional)
The green tea faucet draws water from a separate water tank, which is controlled by a separate thermostat. The
temperature of this water is factory set at 175°F. Check the temperature by holding a thermometer in the
stream of water flowing out of the green tea faucet.
The green tea thermostat is located in the back of the unit, next to the main control board. Turn the adjustment
stem slightly clockwise to increase the temperature, and counter-clockwise to decrease the temperature.
