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.
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.
Warning: Legs are to be adjusted for
leveling the brewer only. Do not use
for height adjustment or extend them
higher than necessary.

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.
Warning: To prevent
electrical shock, t his
unit must be properly
grounded.

Operating Procedures
1. Turn brewer on/off switch (E)to the on position
• The power switch will illuminate to indicate that the brewer has power
and is operating.
• When the ready light (F) illuminates, the brewer is fully up to
temperature. The amount of time required to gain full operating
temperature will vary depending on the electrical configuration that
was ordered, and the temperature of the incoming water.
2. Pre-heat the dispensers.
This step is very important to the overall success of the brewing operation.
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
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.

CAUTION
• Do not remove the brew basket immediately after the brew cycle has finished. Wait until
dripping from the bottom of the brew basket has stopped. Carefully remove the brew basket
while inspecting the inside of the basket for hot coffee that may have been trapped or has not
finished draining.
Service
Warranty
All FETCO brewers come with a limited warranty. All warranty service must be pre-authorized by calling the
FETCO Service Department at [phone].
Principles of Operation
Fill System
The fill system consists of a liquid level control board, a water level probe at the top of the tank, a fill valve, and a fill
tube. As the water rises and touches the probe, continuity is established between the probe tip and the tank body,
and the fill valve closes.
When water is dispensed, the water level drops below the probe. After a 5 second delay, the fill valve opens until
the water touches the probe again.
The 5 second delay, and the speed that water refills the tank during brewing, results in many short bursts of water.
The sound made by these repetitive bursts will let you know the fill system is functioning normally.
The fill system is designed to protect the heaters during both the installation and a loss of the water supply. During
initial installation, or whenever the power switch is turned on, voltage will not be supplied to the thermostat until the
tank fills and water touches the water level probe.
During operation, when water is dispensed and the water level drops below the probe, a fill signal is sent to the fill
valve. If the probe senses no water after 40 seconds, the voltage to the thermostat and the heaters is removed.
Water enters the tank through the fill tube. A hole is drilled in the upper portion of the fill tube to prevent water from
being siphoned from the tank. The fill tube extends to the bottom area of the tank. This introduces cold incoming
water directly to the heaters and away from the dispense assembly.
The water tank can be drained through a valve located inside the lower compartment of the brewer.
Temperature System:
The temperature system consists of an electronic thermostat, a temperature probe, solid state relays (SSR), and
heating elements, and is enabled by the liquid level control board. (See the previous section - Fill Circuit.)
When the water level probe is in contact with water, power is delivered to the thermostat through the liquid level
control board. If the temperature probe senses that the water is not hot enough, the thermostat energizes the
heating elements through the solid state relay (SSR), the water is heated, and the ready light goes off.
Once the water temperature reaches the set point, the thermostat disengages power to the heaters and the ready
light illuminates.
The thermostat is adjusted to 205°F ±2°at the factory. (Slightly lower for high altitude installations.)

8
Timing System:
The timing system consist of the timer and the dispense latch assembly.
When the brew handle is rotated from the stop to the brew position, it pushes the plunger in the latch coil and
closes the micro switch, and the timer starts the timed cycle. It also starts the hot water flowing.
The timer energizes the dispense latch coil, which acts as a magnet, to hold the brew handle in the brew position.
It also lights the brew light. The coil remains energized throughout the brew cycle timed sequence.
When the timer finishes its cycle, it removes voltage from the latch coil. The latch coil then releases the brew
handle, a spring returns it to the stop position, and the flow of water stops. This return opens the micro switch,
stopping voltage from going to the timer. The brew light and the timer are disabled, and wait for the brew handle to
engage the next brew cycle.
Dispense System:
The dispense system is completely mechanical. It is one of the areas that makes FETCO's brewer truly unique.
(See the illustration in this section.)
When you rotate the brew lever down to brew, the end of the dispense tube is submerged in the hot water tank. It
is held in the brew position by the magnetic action of the dispense latch coil.
The brew water travels down the dispense tube to the sprayhead assembly. The flow disc above the spray cutter
controls the rate of flow over the coffee. The standard hole in the flow disc is .240”. Other flow discs are available
for special situations like high levels of bypass.
The sprayhead can be assembled incorrectly during cleaning. Refer to the cleaning label on the brewer for proper
assembly. The flow disc has the flange down, flat side up. The six-triangle spray cutter has the flange up. The
eight-hole spray cutter used in place of the triangle cutter goes bumps down.
A bypass valve and tube are connected to the sprayhead. This valve directs brew water around the outside edge of
the filter paper. The bypass valve is shipped in the closed position from the factory. Each time the valve is
adjusted, the brew volume is affected. Adjustment of the bypass valve is for flavor only.
When the timer circuit releases the brew latch, the dispense tube pops back above the hot water level. The
remaining brew water drains from the dispense system leaving it free of standing water. Steam escaping from the
brew tank through this tube inhibits the formation of lime in the brew system.
The dispense system is clean and semi dry for all but the brief time required for the brew cycle. This eliminates any
chance of lime build-up affecting the brew cycle.
It is very easy to dislodge the dispense tube seals while servicing the dispense system. If you see it leaking
profusely, remove the nut and dispense tube. Reset the seal fully into the recess and carefully insert the dispense
tube. Then secure the locknut before you back the tube into position. (See detailed instructions on page 10.)

Adjustments
Thermostat Adjustment:
During normal operation, the digital readout displays the last two digits of the actual water temperature. When the
adjustment tool is turned, the readout begins flashing to indicate the set point, not the actual temperature. After the
tool is released, the readout stops flashing and displays the actual temperature again.
A red LED lights when the power to the thermostat is on. A yellow LED lights when the thermostat is calling for
heat.
To adjust, turn the adjustment tool. If no adjustment tool is present, a small flat-head screwdriver may be used. The
display will flash, indicating that the display is showing the set point, not the actual temperature.
The dots below the numbers indicate the temp range.
0 dots – less than 100° F
1 dot – between 100° and 200° F
2 dots – over 200° F
Examples:
7 5 = 75°F
8 7 = 187°F
0 3 = 203°F
Timer Adjustment:
The timer has two independent settings, with three dials for each setting. The first dial in each group sets 100
second increments, the second dial sets 10 second increments, and the third dial sets 1 second increments.
A red LED lights when the power to the timer is on. A yellow LED lights when the timer is running.
A small flat head screwdriver is required to adjust the dials.

11
Water Level Control Board:
The board features a jumper to adjust its’ sensitivity for reverse osmosis or other types of ultra-pure water.
The default jumper setting is LO (50K ohms) for normal water. If the brewer tank overfills because of ultra-
pure water, the jumper should be set to HI (100K ohms).
A red LED lights when the power to the board is on.
A green LED lights when the water level probe detects that the tank is full.
A yellow LED lights when the FILL circuit is energized.
A second yellow LED lights when the HEAT circuit is energized.
Bypass Adjustment:
The purpose of the bypass valve is to allow a portion of the brewing water to flow between the brew basket and the
wire insert, directly into the server, without coming in contact with the coffee grounds. The bypass can be adjusted
from 0% to 33% of the total brewing water. Unless requested at the time of order, all brewers are shipped with the
bypass valves closed (0%). Adjusting the bypass always changes the total brew volume, so the timer setting must
always be checked and adjusted.
To adjust the bypass:
• Remove the brewer’s upper cover.
• The bypass valve is located above the brew basket, to the right and to the front, as you are facing
it.
• Remove the brew basket.
• Place a container under the spray head, and a separate container under the bypass hole.
• Turn the bypass valve clockwise to decrease, and counter-clockwise to increase the bypass
amount. A good starting point would be one full turn for each 5% change.
• Brew a full cycle and measure the amount of water in both containers.
• The ratio of the bypass water to the total in both containers is the bypass percentage.
example: ½ gal. bypass + 1 gal. from spray head = 1 ½ gal. total. Bypass = 33.3%.
• Several adjustments may be necessary until the desired results are achieved.

Troubleshooting
Brewing Problem Possible Cause Solution
Brew handle will not stay down Power switch off. -Turn switch on.
No power to the brewer
(Brewer lights are not illuminated)
-Make sure the brewer is plugged in.
-Check the wall circuit breaker / reset
-Turn the brewer power switch off then back on (it has an
internal breaker)
Bad timer or dispense latch
assembly.
(Brew light does not come on and
handle won’t stay down)
-Check for voltage reaching the timer from the dispense
latch assembly if yes replace timer. If no, replace latch
assy.
Bad dispense latch assy.
(Brew light does come on and
handle won’t stay down)
-Replace the dispense latch assembly
Bad dispense latch assembly
(brewer buzzes when in brew cycle)
-Replace the dispense latch assembly
Brew handle stays down but no water is
dispensed
No water reaching the brewer -Make sure the shut off valve is open.
-Check water line for kinks; replace line if necessary
-Check to see if filter is clogged by changing it.
Short brew levels EVERY BREW
Flow discs in spray heads in upside
down
-Reassemble spray heads - bumps on spray cutter face ↓
with flange on flow disc facing ↓
Water filter clogged (See details in next section)
Spray head clogged -Clean and or replace the sprayhead
(One or Both sides are Timer/s are set too low -Advance timers to proper level.
affected and levels are consistent) Incoming Voltage is too low for
timers to function at proper time
sequences
-Reset wall circuit breaker as one side may drop out & not
flag the breaker.
-Call an electrician to find loose connections in the building
Short brew levels SOME BREWS
Water filter clogged.
(problem is worse during
simultaneous brews)
-Replace water filter
Weak dispense latch assembly
(usually buzzes during cycle)
-Replace dispense latch assembly.
(One or Both sides are affected and
levels are erratic)
Water pressure or flow rate is too
low or fluctuates too much to
support a full brew.
(problem is worse in simultaneous
brews)
-Make sure brewer has a dedicated water line
-Ensure that the shut off valve is open all the way (Never
use needle saddle valves)
-Increase the diameter of the water line to the brewer and
or find stable source.
Brew Time required to fill LUXUS are
not the same for both sides
Brewer is not level -With an accurate level, level the brewer front to back and
left to right by adjusting the feet.
High brew levels EVERY BREW
(overfills but does stop)
Timer/s are set too high -Adjust timers down to appropriate level
SOME BREWS Thermal server not empty -Empty the server and try again
Brew basket or filter overflows -Call FETCO Service Dept. to discuss.
[phone]
Weak Coffee Spray head missing -Attach spray head assembly.
Improper dose -Measure and confirm correct dose
Filter papers -Make sure only one paper is used
Cracked dispense tube -See “spray head drips MAJOR”, below
Low brew temperature
(Temperature inside the hot water
tank is set to 205°F, the metal
delivery system drops the temp.)
-Adjust thermostat so the water stream measured at the
bottom of the brew basket, 1/3 of the way through the brew
cycle, equals 190 degrees + or - 5 degrees
Grounds not saturated Spray head missing -Replace spray head
Half batch used incorrectly -Use smaller “half batch” brew basket
-Discourage half batch use
-Investigate the need for a smaller brewer
Water Softener in use -Move brewer water feed to a non-softened source.
Degassing - extremely fresh coffee -Call FETCO Service Dept. to discuss.
[phone]
No bypass EVERY BREW →Bypass valve closed -Open bypass valve
SOME BREWS→Flow disc wrong size or missing -Correct or replace flow disc
Spray head / brew basket drips either
side or both
MINOR
Condensation around the
sprayhead area
-Wipe sprayhead area after brewing; place an empty
container under brew cone when not in use.
Condensation from water tank
dripping through dispense tube
-Insert an empty brew basket and server under brew heads
when not in use

19
Brewing Problem Possible Cause Solution
Spray head / brew basket drips either
side or both
MAJOR
Cracked dispense tube/s
(This problem starts out minor but
gets steadily worse)
-Replace both dispense tubes even if other side is not
dripping
Fill valve not sealing
(Will drip even with power off.)
-See next section - “Brewer won’t stop brewing”, “Bad or
stuck fill valve”.
Brewer won’t stop brewing Dispense tube cracked -See “sprayhead drips MAJOR” above
(not same as high brew levels) Mechanical binding
(brew handle stays down / brew light
turns off at normal time)
-Re-align the brew handle / brass sprayhead tower / and
dispense tube into a straight line by moving brass tower
Water pressure over 75psi -Place a water pressure regulator on the line and reduce to
20-75 psi
Dispense tube drive screw off. A
2.5” screw that connects the handle
to the dispense tube at the brass
sprayhead tower.
(handle returns up and brew lamp
turns off but brewing continues)
-Ensure that the drive screw is straight (can be straightened
by hand while still in the brew handle) and reconnect to the
dispense tube. The flange that the drive screw engages
MUST be held flat against the brass sprayhead tower,
without being able to back out.
Water level probe bad or encrusted
with lime.
(causes brewer to continue filling hot
water tank which will overflow into
the brew baskets)
-Clean lime build up on the probe tip
and/or tank wall. (Holding the probe wire (green) from the
probe end to the body of the brewer should stop the fill if
the probe is bad but the liquid level board is good)
Bad liquid level control board -Replace the LLC board if grounding the probe end of the
(green) probe wire to the body of brewer does not remove
the voltage at the fill terminal on the LLC board.
Bad or stuck fill valve -Rebuild or replace the fill valve if no voltage is on the coil
(it is not magnetic) and it still passes water to the tank.
(Disconnect the outlet side to see if it leaks water to the
tank)
Coffee tastes too strong Incorrect dosage -Measure and confirm the correct amount of coffee required
Short brew levels -See “Short brew levels”, above.
Temperature Problem (brewer
only)
Possible Cause Solution
See also LUXUS problems
Brew water is cold / not hot enough,
ready light is OFF.
(Before proceeding, make sure water tank
refills when water is dispensed. The
brewer will not heat unless the tank is full.)
No power to brewer. -Make sure power switch is on.
-Reset machine circuit breaker.
-Check power connection. (plug or hard wire connection).
-Check building circuit breaker. (Always reset breaker by
switching off, then on.)
Defective liquid level control board.
(No power to thermostat).
-With power on, and water tank full, check LLC board for
120 volts on brown wire and neutral. Replace LLC board if
there is no voltage.
Bad connections on solid state relay.
(No power to heaters).
-Check relay for burned or loose connections. Replace
with high temperature connectors if necessary.
Defective solid state relay.
(No power to heaters).
-Check input and output voltages on relay. 120 volts on
blue wire (input) but no voltage out to heaters indicates a
bad relay.
Bad heating element/s. -Check amperage draw on heater wires. 0 amps = bad
heater.
Brew water is cold / not hot enough,
ready light is ON.
Bad Thermostat
(the thermostat believes that it is at
set temperature)
-Replace the thermostat and or thermal probe. It’s not
possible to trouble shoot the probe.
Low brew temperature setting on
thermostat
-See “Low brew temperature” under “Weak Coffee”
section.
Slow to recover temperature
Brewers with more than one heater
can have just one fail
-Check amperage draw on heater wires. 0 amps = bad
heater.
(Ready light takes along time to come
back on after brewing.)
Hot water tank limed up -Remove access cover to the hot water tank and inspect
for lime. Remove the brewer for shop de-liming if build up
is thick.
Boiling Thermostat set too high for altitude
(Denver etc.)
-Reduce temperature setting to 3 degrees below boiling at
your altitude
Defective thermostat -Replace the thermostat and or thermal probe. It’s not
possible to trouble shoot the probe.
