Keys To A Successful Installation
Electrical:
•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 wiring diagram for the dispenser is located on the inside of the cover.
Plumbing:
•The water line must be flushed thoroughly prior to connecting it to the dispenser to prevent debris from
contaminating the machine. An in-line water filter is strongly recommended.
• Verify that the water line will provide at least 1.5 gallons per minute before connecting it to the dispenser.
• The end of the vent tube must be open to the air, not connected to anything or submerged in liquid.
General:
•The installation must comply with applicable federal, state, and local codes having jurisdiction at your
location.
•Utilize only qualified beverage equipment service technicians for installation. A Service Company Directory
may be found on our web site, http://www.fetco.com.
•Do not adjust the thermostat settings unless absolutely necessary. They are set at the factory for optimum
performance.
Installation Instrucions
Setup
1. Before placing the unit, verify that it will fit in the space intended for it, and
that the counter or table will support its’ weight.
2. Place the unit on its back and screw in the legs.
3. Place the unit on the counter or stand.
4. When the unit is in position, level it front to back as well as side-to-side by
adjusting the legs.
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).
Water Connection
1. The water inlet is a 3/8” male flare fitting.
2. The dispenser can be connected to cold or hot water. Cold water is preferred for best flavor, but hot water will
allow for faster recovery times. Use of an in-line water filter is strongly recommended.
3. Install a shut off valve near the unit 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 unit.
5. Verify that the water line provides at least 1.5 GPM, and that the water pressure is between 20 and 75 psig.
Vent Tube Connection
1. Condensation and steam from the water tank is discharged from the 3/8-inch hose barb fitting on the back of
the unit.
2. Attach a hose (not provided) to the fitting and run it to a drain, sink or a container. The end of the vent tube must
be open to the air, not connected to anything or submerged in liquid.
Electrical Connection
1. Verify that the actual voltage at the electrical service connection is compatible with the specifications on the
unit’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 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
unit, and its location and markings known to the operators.
5. The body of the unit must be grounded to a suitable building ground. A ground
lug is provided 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.
7. 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 unit for leaks in all fittings and
tubes.
2. Turn on the incoming power line and the power switch
3. Within 6 seconds, the water tank will begin filling until the probe at the top of the tank senses the water. The fill
valve will pulse off and on while the tank is filling. The heaters will be disabled until the water probe at the top of
the tank senses water.
4. Review the programming instructions and make any necessary adjustments.
5. Re-attach the cover after one final inspection for leaks.
Operator Training
Review the operating procedures with everyone who will be using the unit. Pay particular attention to the following
areas:
1. Demonstrate the hot water faucet.
2. Demonstrate the shut off valve behind the faucet, and review the safety
warning at right.
3. Show the location and operation of the water shut off valve and the circuit
breaker for the unit.
Warning: Do not disassemble the
faucet without first closing
the shut-off valve behind
the faucet.
Extremely hot water.
May cause serious burns.

Operating Instructions
Operating Instructions
Turn the power switch to the ON position. The power switch will illuminate to indicate that the dispenser has power
and is operating.
When the ready light illuminates, the dispenser is fully up to temperature and ready to dispense hot water through
the faucet. The amount of time required to gain full operating temperature will vary depending on the electrical
configuration, and the temperature of the incoming water.
Safety Precautions:
• Do not hang containers or any other object from the faucet or faucet guard.
• Do not disassemble the faucet without closing the shut-off valve located behind the faucet.
Operating InstructionsOperating Instructions
Operating Principles
When hot water is drawn from the faucet, the fill valve pulses on and off every few seconds to slowly refill the tank.
(See %FV setting in the Programming section.)
By controlling the flow of incoming water, the amount of cold water entering the tank is synchronized with the rate at
which the water can be heated. This ensures an uninterrupted supply of hot water. When dispensing water at a rate
that exceeds the unit’s capacity to heat, the flow of water out of the faucet will be diminished to maintain the proper
temperature.
Maintenance
Quarterly:
• Inspect all fittings and hoses for leaks.
• Inspect inside of tank for lime deposits. De-lime tank and probes if necessary. This procedure should be
done by a qualified service technician.
