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

• 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.

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).

Operating Procedures
Brewing System
Before brewing, always verify the cleanliness of the brew baskets and dispensers.
1. Push the POWER switch to the ON position
2. Prepare the brew basket(s).
3. Place the appropriate dispenser(s) in position under the brew baskets.
4. When the READY light is on, press the BREW button to start the brew cycle
5. The RINSE button (labeled “FLUSH” on some units)
CAUTION:
• The button will illuminate to indicate that the brewer has power and is operational.
• Carefully pull open the drawer holding the brew basket.
• Grasp the brew basket by one handle, and turn it until you can reach both
handles comfortably.
• Grasp both handles and lift the basket out of the drawer. If necessary,
empty and rinse the brew basket.
• Place a paper filter in each basket to be used. Pour the appropriate
amount of pre-measured, ground coffee into the filter. Spread the coffee
evenly in the basket until it is a uniform depth. (The amount of coffee used
will depend on your personal tastes and the recommendation of your
coffee supplier.)
• Place the brew basket back into the drawer. Turn the brew basket to align either one of the handles
with either front corner of the drawer.
• Close the drawer completely. When fully closed, it will be flush with the front surface of the brewer.
• Ensure that the brew-through cover is in place, the dispenser is empty enough to handle the amount of
coffee to be brewed, and the faucets are closed.
• Ensure that the dispensers are pushed all the way in, and that the brew funnels are aligned with the
bottom of the brew baskets.
• When using carts, always set both parking brakes by pressing your foot on the paddle just above each
of the two wheels closest to you. When the brakes are set, a green button extends above the paddle.
To release the brakes for moving, press the green button with your foot.
• The brew cycle will begin immediately, and the BREW button will illuminate. The brew cycle cannot be
started unless the READY light is on.
• Drip delay: When the brew cycle is finished, the BREW button will flash during the drip delay cycle,
indicating that coffee may still be dripping from the bottom of the brew basket.
Optional BREW WAIT setting (See Programming section)
• If the BREW WAIT setting is ON, and the READY light is off when the brew button is pressed, the
BREW and READY lights will begin flashing. When the water has heated to the proper temperature,
the READY light will go on, the brew cycle will begin, and the BREW button will illuminate with a steady
glow.
• If necessary, you may stop the brew cycle at any time by pressing the STOP button. This will reset the
brewer, and you will have to start a new brew cycle from the beginning.
• When this button is pressed, both the brew and bypass valves will open, allowing the maximum
amount of water to flow into the brew basket. Water will flow only while the button is pressed.
• Used primarily to rinse the brew basket at the end of the day, it may also be used to pre-heat the brew
basket before brewing.
• The flow of water will stop if the RINSE button is held in for more than 30 seconds. If a longer rinse
time is desired, release the button momentarily and press it again.
• Caution! If the button is pressed too many times, the dispenser may overflow.
• Do not remove the brew basket or move the dispensers immediately after the brew cycle has
finished. Wait until dripping from the bottom of the brew basket has stopped. This may take
several minutes.
• When removing the brew basket, carefully inspect the inside of the basket for hot coffee that
may have been trapped or has not finished draining.
• Always set both parking brakes whenever carts are not being transported.

Transfer System
1. Before Brewing
• Remove the sight gauge vent cap from the dispenser you want to transfer, and insert the transfer hose
into the top of the sight gauge.
• Ensure that the dispenser, brew basket, and holding tank cover are in place, and that all old coffee has
been drained from the holding tank and dispensers.
• Ensure that the Transfer, Automatic switch is in the “OFF” position, and that the ready light is on.
• Unlock and turn the rinse jet valve on the front of the holding tank to the “on” position to pre-heat the
tank.
• Press and hold the Rinse (or FLUSH) button on each brew head for approximately 30 seconds.
• Press and hold the manual transfer button on each side until the dispensers are empty to pre-heat and
rinse the transfer lines. (The flow of water will stop if the button is held in for more than 30 seconds. If a
longer time is desired, release the button momentarily and press it again.)
• Turn the rinse jet valve to the “off” position.
2. Automatic transfer
3. Manual transfer
4. Stopping the transfer
5. Dispensing coffee from the holding tank
6. End of the day cleaning
• Open the lower faucet on the holding tank until the tank has drained completely.
• Set the Transfer, Automatic push button above the brew head you wish to transfer to the “ON” position.
This can be selected at any time during the brew cycle. The system will wait until the brew cycle is
completed, then automatically transfer the entire contents of the dispenser to the holding tank.
• After a brew cycle has stopped, you can transfer coffee with the manual button in 2 ways:
-Set the Transfer, Automatic switch to the “ON” position, and momentarily press the manual transfer
button. This will start a timed transfer just as if the transfer had been selected during the brew cycle.
-Set the Transfer, Automatic switch to the “OFF” position, and hold the manual transfer button in until the
transfer is complete.
• The flow of water will stop if the manual transfer button is held in for more than 30 seconds. If a longer
transfer time is desired, release the button momentarily and press it again. Repeat as needed.
• You can stop the brew and transfer cycles on either side by pressing the appropriate stop button, or by
pressing the appropriate power button to the off position. You can also shut down both sides at the
same time by pressing the emergency stop palm switch in the center of the brewer. If you stop the
brew head in the middle of a brew cycle, you will have to begin a new brew cycle from the beginning.
You cannot restart a brew cycle after it has been stopped. If you stop the brew in the middle of a
transfer cycle, you can finish the transfer by holding in the Transfer, Manual push button.
• Pressing the Emergency stop push button will remove power to the brewer and cancel all functions on
both sides. If the problem can be isolated to one side only, the power switch to the appropriate side
can be turned off and the emergency stop switch reset. This will allow the good side of the brewer to
continue to function.
• The upper faucet is positioned to allow coffee to be dispensed at a slower rate than the lower faucet
when the tank is nearly full. It will not drain the tank completely due to its’ position.
• The lower faucet will dispense much faster than the upper faucet and will drain the tank completely.
Use caution, especially when the tank is nearly full.
• Ensure that the dispenser, brew basket, and holding tank cover are in place, and that all old coffee has
been drained from the holding tank and dispensers.
• Ensure that the Transfer, Automatic switch is in the “OFF” position, and that the ready light is on.
• Unlock and turn the rinse jet valve on the front of the holding tank to the “on” position.
• Press and hold the Rinse (or FLUSH) button on each brew head for approximately 30 seconds.
• Press and hold the manual transfer button on each side until the dispensers are empty.
(The flow of water will stop if the button is held in for more than 30 seconds. If a longer time is desired,
release the button momentarily and press it again.)
• Turn the rinse jet valve to the “off” position.
• Make one full brew on each side, without coffee in the brew basket, and the Automatic Transfer OFF.
• Manually transfer approximately ½ of the water to the holding tank. This will flush hot rinse water
through the entire system, leaving only clean, fresh water in the pump and lines. Leave the remaining
water where it stands until the system is needed again.
• Remove the brew basket and wipe the area above the basket with a cloth to remove any coffee oils.

Cleaning & Maintenance
Daily
Before brewing, always verify the cleanliness of the brew baskets and dispensers.
At the end of the day, remove the brew basket and wipe the bottom of the spray pan with a cloth to remove the
coffee oils that have collected.
Brew & Bypass Orifices
The flow of water through the brew and bypass orifices may gradually become restricted by the accumulation of
mineral deposits. The orifices should be inspected periodically and cleaned if necessary.
To remove the orifices:
•Remove the brew basket and brew basket drawer.
•Grasp the sides of the spray pan with both hands and turn it counter-clockwise. Being careful not to drop
it, continue turning it with both hands until it comes completely off.
•The brew orifice is located in the center of the threaded piece that held the spray pan. The bypass orifice
is located to the right and to the rear of the brew orifice. Both orifices are stainless steel. Do not remove
the brass fitting located in the same area. This is the vent from the water tank.
•Removal of either orifice requires a 11/16 inch wrench.
•Replace or clean the orifices and reassemble all of the parts.
Transfer Systems: End of the day cleaning
• Ensure that the dispenser, brew basket, and holding tank cover are in place, and that all old coffee has
been drained from the holding tank and dispensers.
• Ensure that the Transfer, Automatic switch is in the “OFF” position, and that the ready light is on.
• Unlock and turn the rinse jet valve on the front of the holding tank to the “on” position.
• Press and hold the Rinse (or FLUSH) button on each brew head for approximately 1 minute.
• Press and hold the manual transfer button on each side until the dispensers are empty.
• Turn the rinse jet valve to the “off” position.
• Make one full brew on each side, without coffee in the brew basket, and the Automatic Transfer in the
OFF position.
• Manually transfer approximately ½ of the water to the holding tank. This will flush hot rinse water
through the entire system, leaving only clean, fresh water in the pump and lines. Leave the remaining
water where it stands until the system is needed again.
• Remove the brew basket and wipe the area above the basket with a cloth to remove the coffee oils that
have collected.
