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:
The power switch has a built-in circuit breaker. To reset, turn to the “off” position, and then back to the “on”
position.
The electrical drawing for the brewer is located on the inside of the lower cover.
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 ¼ gallons per minute before connecting it to the brewer.
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. Remove the brewer’s legs from inside the brew
baskets. The two back legs have round bases. The
front leg has a semi-round base and must be
positioned as shown. 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. Make

sure the front leg is in the position shown.
5. Mark the surface of the counter with the location of
the mounting holes in the legs.
6. Drill ¼” diameter holes in the counter and secure the
legs to the counter with bolts and nuts (not included).
7. Remove the lower cover to access the water and
electrical connections.
Warning: Legs are to be adjusted for
le vel ing the bre w er only. Do not us e
f or height adjustment or extend them
hi gher than nece ssary.
Server Ring Installation (LUXUS TPD-1.5 dispensers only.)
1. Place a LUXUS TPD-1.5 dispenser in the proper position under each brew basket.
2. Mark the surface of the counter top with the circular outline of the dispenser bottom.
3. Remove the dispenser and place a mark at the exact center of the circle.
4. Drill a ¼” hole in the center of the circle.
5. Insert the threaded stud on the bottom of the server ring into the hole and secure it with the wing nut.
6. To install the server rings away from the brewer, place the dispensers in the desired location and follow
steps 2 through 5.
Top Cover Instructions
1. Remove all screws. The back edge of the top cover fits tightly over

the vents on the back of the brewer. Carefully lift the front of the
cover up and back.
2. Once the cover is at a 45° angle, it can be lifted completely off.
1. To replace the cover, hold the cover at approximately a 45° angle
and place the back edge over the vents on the back of the brewer.
2. Lower the front of the cover while pulling it over the top of the
brewer. The cover should flex slightly. Install all screws.

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 ¼ gallons per minute and that the water pressure is between
20 and 75 psig.
Electrical Connections
1. Verify that the actual voltage at the electrical service connection is compatible with the specifications on the
brewer’s serial number label.
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 control board disables the heaters until the tank is full of water. The
heating process will start automatically when the tank has filled.
3. A fused disconnect switch or circuit breaker on the incoming power line must be conveniently located near
the brewer, and its location known to the operators.
4. The body of the brewer must be grounded to a suitable ground. A ground lug is provided in the brewer next
to the terminal block. Use only 10 gauge copper wire.
5. Electrical connections must be secured in-place within the
unit to meet national and local standards.
6. Finally, connect the incoming power wires to the terminal
block in accordance with applicable codes.

Final Setup
1. Turn on the water supply and inspect inside and outside of the brewer for leaks in all fittings and tubes.
2. Turn on the incoming power.
3. Turn on the brewer’s main power switch.
4. Within 6 seconds, the hot water tank will begin filling until the probe at the top of the tank senses the water.
5. The control board will disable the heaters until the tank is full.
6. The brewer will be ready for operation as soon as the ready light comes on to show that the water tank is
up to temperature. The time required to reach brewing temperature will vary according to the electrical
configuration ordered.
7. 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.
8. 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.
Operating Training
Review the operating procedures with whoever will be using the brewer. Pay 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 which will drip out through the brew baskets.
1/4 cup discharging overnight is possible. Place an appropriate container under each brew basket when
not in use.

READY
FETCO avoids the damaging affects of heat on fresh brewed coffee by using
highly insulated dispensers. The dispenser must be pre-heated with hot water
H
from the brewer. This preheating process ensures that the coffee in the first
brew starts out hot. Significant heat loss will occur when brewing coffee into a
cold dispenser. Preheating is not required for subsequent brews unless the
dispenser remains empty for an extended period of time and has cooled down.
• Slide the empty brew basket(s)
(D) into their rails and put the empty
dispenser(s) in position under the basket for preheating. Select the
half batch mode,
(A) if you have this option.
• When the ready light illuminates, start a brew cycle by rotating the brew
lever
(B) to the brew position. This starts clean hot water flowing into
the brew basket and then into the dispenser.

• Stop the cycle when each dispenser is approximately 1/2 full by moving
the brew lever to the off position. This interrupts the brew cycle and
resets the brewer.
• Let the dispensers stand 10-15 minutes, or until use, to allow the heat
from the water to be absorbed by the dispensers.
3. Remove the brew baskets from the brewer when you are certain that the flow of hot water has stopped
from the bottom of the basket.
• H model brewers will have a safety bar
(C) in front of the brew basket to make removing the brew
basket a 2-handed operation. This was done to help draw attention to the basket so the operator will
notice any residual hot water or coffee.
• Place a paper filter in each basket to be used. Pour into the paper filter the appropriate amount of pre-
measured, ground coffee. The amount of coffee used will depend on your personal tastes and the
recommendation of your roaster.
• Slide the brew basket back into the rails on the brewer. Insure the latch is outside of the basket.
4. Carefully drain any coffee or preheating water from the dispensers through the faucets before starting
a coffee brewing cycle.
• Overflowing of the dispensers may result if the dispensers are not completely empty when the brew
cycle begins. Verify by opening the faucet over an appropriate container or drain. The last several
cups cannot be seen in the sight gauge tube.
• CAUTION: both the coffee or water may still be hot enough to cause burns, so be careful when
draining the dispensers
5. Place the thermal dispenser(s) in position under the brew baskets.
• Ensure that the brew funnel is in place, the dispenser is empty, and the faucet is closed. If you are
using TPD-1.5 dispensers (CBS_52H15 only), also make sure the vent cap on the sight gauge is open.
• The twist lock cover (TPD-1.5 dispensers) is for transporting the dispenser only. It must be removed
before placing the dispenser under the brew basket.
6. Start the brew cycle in the same manner used to start the water used to preheat the dispensers.
• It will not be necessary to interrupt the cycle while brewing coffee. The brewer will return to the
stopped and ready status automatically.
• It is normal for the ready light to go out after the start of the brew cycle. On twin brewers, there is
enough hot water in the brewer to support a second brew, even if the ready light is off. After brewing
on both sides, you must wait for the ready light to come back on.
• The electrical configuration and the electrical power connected to the brewer will determine how long
before the ready light comes back on for the next brew.
