Installation  
(For Qualified Service Technicians Only)  
Keys To A Successful Installation  
If not installed correctly by qualified personnel, the brewer may 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.  
Universal wiring: This brewer can be configured for single or three phase operation. Conversion  
instructions are described later in this section.  
The electrical diagram and universal wiring instructions are 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 1 gallon per minute for the CBS-2051e, and 1.5 gallons per  
minute for the CBS-2052e and 2052e20 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.  
Warning: Legs are to be adjusted for  
leveling the brewer only. Do not use  
for height adjustment or extend them  
higher than necessary.  
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 1 gallon per minute for the CBS-2051e, and 1.5 gallons per minute  
for the CBS-2052e and 2052e20, and that the water pressure is between 20 and 75 psig.  
6. 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.  
6
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. 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. A terminal block is provided 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.  
Warning: To prevent  
electrical shock, this  
unit must be properly  
grounded.  
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  
national and local standards.  
7. Connect the incoming power wires to the terminal block in accordance with applicable codes.

The CBS-2052e and CBS-2052e20 are shipped from the factory configured for either single phase or three  
phase operation, depending on the version that was ordered. A tag attached to the terminal block will indicate  
which way the unit was configured.  
Notice: The following conversion should be performed only by a qualified beverage equipment  
service technician or electrician.  
For brewers manufactured before August, 2005:  
To change the configuration, arrange the heater wires as shown below. Make sure that all connections are  
tight. These instructions are also located on the inside of the lower cover.

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. Turn on the incoming power.  
3. Press the brewer’s main power switch, which is hidden behind the  
front leg of the brewer. The control panel on/off switch will begin  
flashing. Press this switch.  
4. Within 6 seconds, the hot water tank will begin filling until the water is  
sensed by the probe at the top of the tank. The display will read  
“FIL”. The heaters will be disabled by the control board until the tank  
is full.  
5. While the water is heating, the display will read “LO” and the actual  
water temperature will be displayed. After the water has reached the  
set temperature, the display will be blank. There is no “ready” light.  
6. Review the Operating Instructions. Brew one full batch (water only)  
on each side 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 #60 – 63 in the  
Advanced Settings & Diagnostics section.  
7. Re-attach the covers after one final inspection for leaks. Look  
closely in the top of the brewer at the dispense fittings during this  
inspection.  
Operator Training  
Review the operating procedures with whoever will be using the brewer.  
Pay particular attention to the following areas:  
1. 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.  
2. Don't remove the brew basket 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 thermal  
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. 1/4 cup  
discharging overnight is possible. Place an appropriate container  
under each brew basket when not in use.  
7. 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.
