The power management feature allows only one side of the
brewer to heat at any given time, which limits the steam
demand required for operation.
All steam heated brewers are supplied with the
following:
Steam inlet strainer, with ½” FPT
(¾” FPT on CBS-72A/AT (-6) )
Steam trap, with ½” hose barb

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.
Damage resulting from improper installation is 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 power connection to L1 on the terminal block must be at least 105 volts. Less than 105 volts will
cause erratic behavior from the brewer.
• Push button circuit breakers are located on the front of the brewer, behind the dispensers.
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.
General:
• Utilize a qualified beverage equipment service technician for installation.
Brewer Installation
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 to the installation and operation of FETCO
products.
Brewer Set-up
• Place the brewer stand (for mobile cart systems) or counter (for stationary systems) in the desired location.
Allow at least 1 foot of space between the wall and the back of the stand or counter.
For easy access and visibility, electrical shut off switches, circuit breakers, water valves, and filters should
not be located directly behind the brewer.
• Using a carpenter’s level, adjust the legs until the stand or counter is perfectly level front-to-back, and left-
to-right.
• Each leg has a flange with 2 holes for bolting the stand or counter to the floor (required for safety). Mark
the location of the holes on the floor.
• Set the stand or counter aside, and drill holes in the floor as marked. The materials used will depend on
the floor material.
• Bolt the stand or counter to the floor, and double check to make sure it is level.
• The brewer is shipped lying on its’ back. Before standing it upright, remove the front cover. There is no
need to remove the 2 top covers.
• Place the brewer on top of the stand or counter. This requires at least 3 people, 4 if possible.
• Bolt the brewer to the stand or counter, using the nuts and bolts provided.
Drip Tray Drain Connection
• A kitchen sink style drain is provided on the drip tray for connection to a 1 ½ inch drain pipe.
• Before connecting the drain, the customer should select one of the three available height positions for
mounting the drip tray. Holes are provided in the back of the counter for each of the available positions.
Water connection
• Caution
connect the incoming water to these fittings.
• The water connection is a single 3/8 inch male flare fitting, located inside the lower compartment.
• 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.
(stationary systems only)
! The hose barb fitting(s) protruding from the back of the unit are the tank drains. DO NOT
5
• 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.
• Before connecting the water line to the brewer, flush the line and water filter thoroughly to remove any
debris.
• Connect the water line to the brewer, and turn on the water to check for leaks.
Electrical connection
(Steam heated brewers - see next section)
• Verify that the actual voltage at the electrical service connection is compatible with the specifications on the
brewer’s serial number plate. Make sure the electrical service includes neutral.
• 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.
• 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.
• Make sure that both power switches are in the “off” position. The buttons should be in the “out” position.
• Connect the power, neutral, and ground wires to the terminals in the brewer.

• Turn on the building circuit breaker. Do not
turn on the brewer’s power switches yet.
• At the brewer’s terminal block, verify that the correct voltage is between terminals, according to the
diagram above.
• CBS-71A - press the power switch. CBS-72A - press only the power switch on the brewer’s left side. The
power switch will illuminate. After a delay of 5-6 seconds, the tank should begin filling with water.
• CBS-72A - You can press the right side power switch at any time to begin filling the other tank, but this will
cause the first tank to fill more slowly. To fill the first tank as fast as possible, wait until it has filled
completely before pressing the right side power switch.
• The heating process will begin after the water has reached a safe level, but before the tank has filled
completely. Approximately 10-15 minutes after the tank has filled, the ready light will illuminate, indicating
that this side of the brewer is at the proper temperature and ready to operate.
Steam Heated Brewers
Electrical connection
• The electrical connection is 120 VAC, single phase, 2 wire plus ground. A power cord with a standard 5-
15P plug is provided. The brewer will draw a maximum of 2.5 amps.
Steam connection
• The steam line must be clean and free of any debris. A shut off valve should be located near the brewer.
• The steam inlet is ½ “ or ¾” FPT, and is equipped with a strainer. There are two steam traps with ½ hose
barbs.
• The steam pressure should be at least 10 PSI, and must not exceed 15 PSI.
• A shut off valve should be located near the brewer.
• To prevent backups, the ends of the hoses connected to the steam traps must be free (not connected or
submerged).
