Description & Features
The CBS-2021eP brews directly into a 1.9L bowl server or our LUXUS® L3S-05 half-gallon thermal dispenser.
The CBS-2021eG brews directly into our LUXUS® L3D-05 half-gallon thermal dispenser.
The CBS-2021 series features our patented intermittent spray over technology, which works as follows.
The following variables are programmed for each batch size:
Brew volume Prewet percent
Brew time Prewet delay
Bypass percent Drip delay
Using these variables, the software calculates how much water to use for prewetting, bypass and brewing. The
total brew time is divided into several 30-second cycles. Within these cycles, the software calculates how long to
spray water over the coffee grounds, and how long to pause before the next cycle begins.
Features
Two fully programmable batch sizes Cascading Spray Dome
Adjustable prewetting cycle Electronically controlled hot water service
Adjustable bypass Dual coffee filter sizes
Brew temperature protection

Installation
(For Qualified Service Technicians Only)
Keys To A Successful Installation
If not installed correctly by qualified personnel, the brewer will not operate properly and damage or injury may
result. Damages resulting from improper installation are not covered by the warranty.
Here are the key points to consider before installation:
Electrical:
All FETCO brewers require NEUTRAL. Ground is not an acceptable substitute. Installation without neutral
may cause damage to the electronic components.
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:
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.
Verify that the water line will provide at least ½ gallon per minute before connecting it to the brewer.
General:
Utilize only qualified beverage equipment service technicians for installation. A Service Company Directory
may be found on our web site, http://www.fetco.com.
Installation Instructions
Brewer Setup
1. Review the Dimensions for the unit you are installing. Verify that the brewer will fit in the space intended for it,
and that the counter or table will support the total weight of the brewer and dispensers when filled.
2. Place the brewer on the counter or stand.
3. When the brewer is in position, use a bubble level to level
the brewer front to back as well as side to side by
adjusting the legs.
Water Connection
1. Water inlet is a ¼ inch female pipe fitting.
2. 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.
3. Flush the water supply line and filter before connecting it to the brewer.
4. Verify that the water line will provide at least ½ gallon per minute, and that the water pressure is between 20
and 75 psig.
Electrical Connection
1. Verify that the actual voltage at the electrical outlet is compatible with the
specifications on the brewer’s serial number label.
2. The temperature and water tank fill level are pre-set at the factory.
There is no need to turn off the heaters during the installation process.
The control board disables the heaters until the tank is full of water. The
heating process will start automatically when the tank has filled.
Warning: Legs are to be adjusted for
leveling the br ewer only. Do not use
f or hei ght adjustment or extend them
higher than necessary.
Warning: To pr event
electrical shock, this
u nit must be properly
grounded.

Final Setup
1. Turn on the incoming water supply line and inspect both inside and outside
of the brewer for leaks in all fittings and tubes
2. Plug the brewer into the appropriate electrical outlet.
3. Turn on the brewer’s main power switch (located on the back of the brewer).
The ON/OFF switch will begin flashing, indicating it is in the OFF position.
The display will read “PRESS KEY”.
4. Press the ON/OFF switch so it is in the ON position (lit, not flashing).
(Note: The switch must be pressed and held momentarily.)
5. Within 6 seconds, the hot water tank will begin filling until the probe at the top
MAIN
POWER
SWITCH
of the tank senses the water. The display will read “FILL”. The control board
will disable the heaters until the tank is full.
TANK
6. While the water is heating, the display will read “HEAT” and the actual water
temperature will be displayed. After the water has reached the set
temperature, the display will read “READY”.
7. Review the Operating Instructions. Brew one full batch (water only) to
confirm proper fill levels. The brewer is factory set with water only (no coffee)
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. See the Advanced Settings & Diagnostics section.
8. Re- inspect for leaks.
Operator Training
Review the operating procedures on the next page with whoever will be
using the brewer. Pay particular attention to the following areas:
1. Demonstrate the hot water faucet, paying particular attention to the
safety warning and the correct cup position.
2. Always pre-heat the dispensers before the first use of each day by
filling them half way with hot water, and letting them stand for at least
15 minutes.
3. Do not remove the brew basket until it has stopped dripping.
4. Make sure the dispenser is empty before brewing into it.
5. Show how to attach covers, close, and or secure the thermal
ON/OFF
Flashing = OFF
Lit = ON
Dark = Main Power Off
dispensers for transporting.
6. Demonstrate the daily and weekly cleaning procedures on page 10.
7. Show the location and operation of the water shut off valve as well
as the circuit breaker for the brewer.
8. Steam from the tank will form condensation in the vent tube. This condensation will drip into and then out of the
brew basket. 1/4 cup discharging overnight is possible. Place an appropriate container under the brew basket
when not in use.
9. We recommend leaving the power to the brewer on overnight. The water tank is well insulated and will use very
little electricity 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.
Tank Drain
The water tank must be drained before certain maintenance procedures, and whenever the unit is to be relocated
or shipped.
1. Disconnect power to the brewer.
2. Move the brewer near a sink or obtain an appropriate container to hold the water from the tank.
(CBS-2021eP: 1.6 gal. / CBS-2021eG: 2.5 gal.)
3. Remove the tank cover and allow the tank to cool to a safe temperature.
4. The tank drain is located on the back of the brewer. Turn the drain plug one-quarter turn in either direction.
5. Pull the plug out far enough to expose the silicone tube.
6. Using pliers, loosen the hose clamp and move it back over the tube.
7. Crimp the tube an inch or two away from the drain plug to prevent water from flowing.
8. Use the other hand to pull the drain plug out of the tube.
9. Release the crimped tube and allow the water to flow into the sink or container.
