Installation
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 website, http://www.fetco.com.
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. When the unit is in position, use a bubble level to level it front to back and side
to side by adjusting the legs.
Warning: Legs are to be
adjusted only for
leveling the unit.
Do not extend them
higher than necessary.
Water Connection
1. Water inlet is a ¼ inch female pipe fitting.
2. 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.
3. Flush the water supply line and filter before connecting it to the unit.
4. Verify that the water line provides at least ½ GPM, and that the water pressure is between 20 and 75 psig.
Electrical Connection
1. Verify that the actual voltage at the electrical outlet is compatible with the unit’s
specifications. The temperature and water tank fill level are pre-set at the factory
and there is no need to turn off the heater during the installation process. The
heating process will start automatically when the tank has filled.
Warning: To prevent
electrical shock,
this unit must be
properly
grounded
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. Plug the unit into the appropriate electrical outlet.
3. Turn on the unit’s main power switch (located on the back).
The ON/OFF switch will begin flashing, indicating it is in the OFF position.
The display will read “PRESS KEY”.
4. Press the ON/OFF switch so it is in the ON position (lit, not flashing).
MAIN
POWER
SWITCH
(Note: The switch must be pressed and held momentarily.)
5. Within 6 seconds, the water tank will begin filling until the probe at the top of
TANK
the tank senses the water. The display will read “FILL”. The control board will
disable the heaters until the tank is full.
6. While the water is heating, the display will read “HEAT” and the actual water
temperature will be displayed. After the water has reached the set
temperature, the display will read “READY”.
7. Re- inspect 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 and drip tray, paying particular
attention to the safety warning.
2. Demonstrate the cleaning procedures listed on the following page.
3. Show the location and operation of the water shut off valve and the circuit
breaker for the unit.
Tank Drain
ON/OFF
Flashing = OFF
Lit = ON
Dark = Main Power Off
The water tank must be drained before certain maintenance procedures, and whenever the unit is to be relocated
or shipped.
1. Disconnect power to the unit.
2. Move the unit near a sink or obtain a container to hold the 2 gallons of water from the tank.
3. Remove the tank cover and allow the tank to cool to a safe temperature.
4. The tank drain is located on the back of the unit. Turn the drain plug one-quarter turn in either direction.
5. Pull the plug out far enough to expose the silicone tube.
6. Using pliers, loosen the hose clamp and move it back over the tube.
7. Crimp the tube an inch or two away from the drain plug to prevent water from flowing.
8. Use the other hand to pull the drain plug out of the tube.
9. Release the crimped tube and allow the water to flow into the sink or container.

Displays the following messages:

–Water is heating after power turned ON.
HEATING – Water is heating during
normal operation.
READY – Water temperature is at the
correct setting.
ERROR – Incorrect setup or settingsmachine will not function.
\ Hot Water Faucet
Pull handle forward to dispense water.
WARNING! Extremely hot water – may
cause serious burns.
Instructions
1. Make sure the drip tray is in place before turning the unit on. Steam and condensation from the water tank is
released into the drip tray whenever the unit is on.
2. Turn the main power switch and control panel switch on.
3. When the diplay reads “READY”, the unit has heated to the proper temperature.
4. Hold a cup or other container under the faucet and pull the faucet handle forward to dispense hot water. Larger
containers such as carafes, pitchers, or large mugs may be placed directly on the drip tray.
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 #60 - Fill Duty Cycle 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.
Cleaning & Maintenance
Daily: Check the drip tray and empty if necessary.
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
performed by a qualified service technician.

Programming
• To enter Programming mode, first turn the main power switch OFF.
• Press and hold the UP button while turning the main power switch ON.
• Release the UP button as soon as the software version is displayed.
Example: (actual version may vary)
VER 0.7B
• Press the DOWN button to advance
to the first setting – Water Temperature.
7 201 F
• Press the UP button to adjust the value of the setting. After the maximum value has been reached, the value will
loop back to the beginning of the range. The DOWN button cannot be used to decrease the value.
• Continue to use the DOWN button to go to the next address and the UP button to change the value until all
settings are programmed.
• To exit Programming and save changes, press and hold the DOWN button for approximately 2 seconds.
• The POWER switch may be used to exit programming without saving new settings.
