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.
Damage 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 electronic controls require at least 105 volts. Less than 105 volts will cause erratic behavior from the

brewer. On 120/208-240 volt models, the #2 terminal on the terminal block provides power to the controls.

 The circuit breaker is located on the back of the brewer. To reset it, press and release the white button.
 The electrical drawing for the brewer is located on the inside of the lower cover.

Plumbing:

 This equipment is to be installed in compliance 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-31, and ½ gallon per minute

for the CBS-32 before connecting it to the brewer.

General:

 Use 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. “Aap” model brewers are shipped with the legs attached. These legs are factory adjusted to one of two
settings. One setting is for the 2.2 liter air pot (narrow).* The other setting is for the 3.0 liter air pot (wide).*
The legs for the “A” model brewers are packed inside the brew basket, and must be attached by the
installer. 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

Warning: Legs are to be adjusted for

le veling the brew e r only. Do not use
f or height adjustment or extend them
higher than necessary.

the back and base of the brewer body for the
connections.

*Adjusting leg settings: Two holes are provided to adjust the width of the leg rails. Remove the ¼-20 allen head bolt with a
3/16 allen wrench.and move rail to line up with desired hole. Fasten ¼-20 allen bolt. Repeat process on other side.

Water Connection

1. Water inlet is a 1/4 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-31, and ½ gallon per minute
for the CBS-32, 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 installation has been
completed.
