Description & Features
The CBS-2041 and CBS-2042 feature our patented intermittent spray over technology, which works like this:
The following variables are programmed for each batch size:
Brew volume
Brew time
Bypass percent
(Percentage of the brew volume)
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. The bypass valve opens
at the beginning of the brew cycle and dispenses the correct amount of water all at once.
Features
Two fully programmable batch sizes per side
Adjustable prewetting cycle
Adjustable bypass
Electronically controlled hot water service
Prewet percent (Percentage of the brew volume)
Prewet delay (The time between prewetting and the brew cycle.)
Drip delay (The time between the end of the brew cycle
and the unlocking of the brew basket.)
Magnetic brew basket sensor
Brew basket safety locks
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 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 electrical diagram is located on the inside of the lower cover.
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 ¼ gallon per minute for the CBS-2041, and ½ gallons per
minute for the CBS-2042 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. The brewer’s legs are shipped inside the brew baskets.
Remove the brew basket(s) and the coffee dispenser(s).
Place the brewer on its back and screw in the legs.
3. Place the brewer on the counter or stand.
4. When the brewer is in position, level it front to back as well
as side to side by adjusting the legs.
5. Remove the lower cover to access the water and electrical connections. Knock-outs are provided in the back
and base of the brewer body for the connections.
Water Connection
1. Water inlet is a 3/8 inch male flare fitting.
2. The brewer can be connected to a cold or hot water line. Cold water is preferred for best coffee flavor, but hot
water will allow for faster recovery times.
3. 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.
4. Flush the water supply line and filter before connecting it to the brewer.
5. Verify that the water line will provide at least ¼ gallon per minute for the CBS-2041, and ½ gallon per minute
for the CBS-2042, and that the water pressure is between 20 and 75 psig.

Electrical Connection – US & Canada
1. Verify that the actual voltage at the electrical service connection is compatible with the specifications on the
brewer’s serial number label. Make sure the electrical service includes neutral.
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 heaters are disabled by the control board until the tank is full of water. The
heating process will start automatically when the tank has filled.
3. The CBS-2041 is factory equipped with a 120 V cord and plug. The CBS-2042 has only a terminal block for
connecting the incoming power wires. Consult local codes to determine if a cord and plug can be installed, or if
the unit must be hard wired.
4. 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.
5. The body of the brewer must be grounded to a suitable building ground.
A ground lug is provided in the brewer next to the power terminal block.
Use only 10 gauge copper wire for grounding.
6. Electrical connections must be secured in-place within the unit to meet

unit must be properly

7. Finally, connect the incoming power wires to the terminal block as shown in accordance with applicable codes.
