Description & Features
The TBS-2121 Iced Tea EXTRACTOR® series brewer features our universal spray over technology.
The following variables are programmed for each of nine menus (3 batches Left, Center, Right positions)
Brew volume Prewet percent (Percentage of the brew volume)
Brew time Prewet delay (The time between prewetting and the brew cycle.)
Adjustable number of pulses
Dilution volume & time in cycle Expandable separately available base platform system
Drip delay (The time between the end of the brew cycle to
empty the brewbasket and end of the brewing cycle.)
Using these variables, the software calculates how much water to use for prewetting, brewing, and dilution. The
total brew time is divided into several cycles. Within these cycles, the software calculates how long to spray
water over the tea, and how long to pause before the next cycle begins.

Installation
(For Qualified Service Technicians Only)
Guide to A Successful Installation
If not installed correctly by qualified personnel, the brewer will not operate properly and damage may result.
Damages resulting from improper installation are not covered by the warranty, and will void the warranty.
Here are the key points to consider before installation:
Electrical:
All FETCO brewers require an electrical ground wire. Installation without grounding is dangerous.
Verify voltages, polarity, circuits, and circuit breaker access before attaching equipment.
The electrical diagram is located in the Users Guide and online at www.fetco.com.
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.
Plumbing:
All installations must comply with applicable federal, state, or local plumbing codes.
An inline water filter is highly recommended. It should be installed after a water shutoff valve and in a
position to facilitate filter replacement.
The water line and newly installed filter cartridge must be flushed thoroughly prior to connecting it to the
brewer to prevent debris from contaminating the machine.
Verify that the water line will provide a flow rate of 1½gpm/ (5.7lpm) per minute and water pressure is
between 35-50 psig (241-345kPa) before making any connections. A pressure regulator may be
required
Install a backflow prevention device if required. Many municipalities require a recognized backflow
preventer. Usable on all hot beverage and cold beverage equipment is a WATTS® SD-2 or SD-3.
These spring loaded double check valve models are accepted by most zoning authorities.
The check valve should be as close to the water supply inlet of the beverage equipment as possible.
General:
Utilize only qualified beverage equipment service
technicians for installation.

Installation Instructions
Brewer Setup
1. Review the dimensions for the unit and verify that it will fit properly in the space intended for it. Verify that
the counter or table will support the total weight of the brewer and dispensers when filled (specifics-page 3).
Allow a counter for a unit that is 19 ½ inches/495mm deep from front to the wall
2. Place the brewer on the counter or stand.
3. When the brewer is in position, level it front to back as well as side-to-side by adjusting the legs.
4. For Sweetener Delivery units, provide space near the TBS-2121 for the sweetener boxes
Water Connection
1. Water inlet is a ¼ inch male flare fitting.
2. Connect brewer to a cold water supply line only.
3. Install a water shut off valve near the brewer to facilitate service. An in-line water filter should be used,
it should be installed after the water shut off valve and in a position to facilitate filter replacement.
4. Flush the water supply line and filter before connecting it to the brewer
5. Verify that the water line will provide at least 1½gpm (5.7lpm) per minute and also that the water
pressure is between 35-50 psig (241-345kPa) before connecting it to the brewer.
6. Note that during use all water filters will clog and will slow the water flow. The reduced water flow
affects the operation of the TBS-2121. Always schedule changing water filters per the manufactures
specification.
7. Unit was calibrated to a stable, non-fluctuating water supply at 45 psi. Unit may require a pressure
regulator OR calibration for other water pressures. See “Dill. Volume” setting in “PROGRAMMING”
menu
Electrical Connection
1. Verify that the actual voltage at the electrical service connection is compatible with the specifications on
the brewer’s serial number label.
2. Plug in unit into an appropriate 120v circuit. Note that the plug is either a NEMA 5-15P or NEMA 5-20P.
The NEMA 5-15P is for a minimum 15 amp circuit the NEMA 5-20P a minimum 20 amp circuit [USA].
3. The temperature and the fill level of the water tank are pre-set at the factory. There is no need to turn
off the heaters during the installation process. The control board automatically disables the heaters until
the tank is full of water. The heating process will start automatically when the tank has filled with water.

WARNING—DANGER
Do not plug-in or electrically
energize this equipment, or attempt
operation without all covers in place
and all screws fastened
.
Final Setup
1. Turn on incoming water supply line and carefully inspect both inside and
outside of the brewer for leaks in all fittings and tubes
2. Turn power on—by pressing the brewer’s main power switch (located on
the lower right of the back of the equipment)
3. The water tank will begin filling. FETCO Home Screen #1 will read
“FILLING”.
4. When the water level rises and is sensed by the probe at the top of the
tank the heaters will activate
5. Heaters are automatically disabled until the tank is full.
6. While the water is heating Screen #2 “HEATING” will display and the
actual water temperature will be displayed.
7. After the water has reached the set temperature Screen #3 will display
“READY”
8. Review the Operating Instructions. Brew one full batch (water only) to
confirm proper fill levels. The brewer is factory set with water only (no tea)
to dispense the correct amount of water. If the actual volume is slightly
different from the programmed volume, fine-tuning the brewer may be
necessary.
9. Re-attach the covers after one final inspection for leaks. Look closely in
the top of the brewer section at the dispense fittings during this
inspection.
Danger: Do not operate without covers in place

Operator Training
Review the operating procedures for the brewer.
Pay particular attention to the following areas:
1. Always have an empty dispenser under the brewbasket
2. Don't remove the brew basket from a brewer until it has stopped dripping.
3. Make sure the dispenser is empty before brewing into it.
4. Show how to attach covers, close, and/or secure the dispensers for transporting.
5. Show the location and operation of the water shut off valve as well as the circuit breaker for the brewer.
6. Steam from the tank will form condensation in the vent tubes. This condensation will drip into and then out of
the brew baskets. Up to 1/2 cup/118cc discharging overnight is possible. Place an appropriate container
under the brew basket when not in use.
7. We recommend leaving the power to the brewer on overnight. The water tank is well insulated and very little
electricity is used to keep the tank hot. Leaving the brewer in the “ON” position will also avoid delays at the
beginning of shifts for the brewer to reach operating temperature.
Cleaning & Maintenance
After Each Brew:
1. Dispose of used filter and rinse brew basket.
Sprayhead
2. Never strike a brewbasket or hit it against a hard surface.
This will damage the brew cone, and may damage the brewbasket support rails
3. Rinse dispensers before reuse.
Every Day:
1. Wash brew basket with hot sudsy water.
2. Pull CSD from the spray head, it is magnetically attached. Use gloves or a heavy towel. Æ
