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:

 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 L2 on the terminal block must be at least 105 volts. Less than 105 volts will

cause erratic behavior from the brewer.

 The power switch has a built-in circuit breaker. To reset it, 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 ½ gallons per minute for the CBS-51H, and 1 ¼ gallons per

minute for the CBS-52H before connecting it to the brewer.

General:

 Utilize 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. The brewer’s legs are shipped inside the brew baskets. Remove the brew basket(s) and the coffee dispenser(s). 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 and side to side by adjusting the legs.

5. Remove the lower cover to access the water and electrical connections. Knock-outs are provided in the back and base of the brewer body for the connections.

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 ½ gallons per minute for the CBS-51H, and 1 ¼ gallons per minute for the CBS-52H, 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 install has been completed.

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.

Electrical Connection

1. Verify that the actual voltage at the electrical service connection is compatible with the specifications on the

brewer’s serial number label. Make sure the electrical service includes neutral.

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 heaters are disabled by the control board until the tank is full of water. The heating process will start automatically when the tank has filled.

3. Only 120vac powered units are shipped from the factory with power cords and plugs attached. For other voltages, a terminal block is provided for connecting the incoming power wires. Consult local codes to determine if a cord and plug can be installed, or if the unit must be hard wired.

4. 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.

5. 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.

6. Electrical connections must be secured in-place within the unit to meet national and local standards.

Warning : To prevent

electrical shock, this u nit must be properly gro un ded.

7. Finally, connect the incoming power wires to the terminal block in accordance with applicable codes.

Final Setup

1. Turn on the incoming water supply line and inspect both 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 water is sensed by the probe at the top of the tank.

5. The heaters will be disabled by the control board until the tank is full.

6. The brewer will be ready for operation as soon as the ready light comes on to signify 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.

Operator Training

Review the operating procedures with whoever will be using the brewer. Pay particular 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. This condensation will drip into and then out of the brew baskets. 1/4 cup discharging overnight is possible. Place an appropriate container under each brew basket when not in use.

7. We recommend leaving the power to the brewer on overnight. The water tank is well insulated and will use very little electricity to keep the tank hot. Leaving the brewer in the on position will also avoid delays at the beginning of shifts for the brewer to reach operating temperature.

Operating Procedures

1. Turn brewer on/off switch (

• The power switch will illuminate to indicate that the brewer has power

and is operating.

• When the ready light

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)

dispenser(s) in position under the basket for preheating. Select the half batch mode,

• 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

basket a 2-handed operation. This was done to help draw attention to the basket so any residual hot water or coffee will be noticed by the operator.

• 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, 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.

Service

Warranty

All FETCO brewers come with a limited warranty. All warranty service must be pre-authorized by calling the FETCO Service Department at (800) 338-2699.

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 no water is sensed by the probe 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, 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 mercury relay, 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.)
