NEW TECHNOLOGICAL FEATURES
The FETCO hot water dispenser uses new t∫f Touch Function Selector Technology to operate the hot water dispenser.
The t∫f Touch Function Selector buttons (above and below display screen) alternately dim and brighten when selection is not active.
Dispensing and Feature Selections activate when touched. The front panel is clean and uncluttered.
The display screen shows four temperature selections and the readiness status of each level.
Programming, display and error codes are interactive and more intuitive.
Float indicator is built into drip tray to help simplify maintenance and cleaning.

Water inlet fitting: ¼ inch female pipe fitting
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 the weight of the HWD-2105 when filled.
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.
Water Connection
1. Water inlet is a ¼ inch ¼ inch male flare fitting.
2. Install a shut off valve near the unit to facilitate service.
3. Install a backflow prevention device, a spring loaded double check valve such as a
WATTS® SD-2 or SD-3, two models accepted by most zoning authorities. The
check valve should be as close to the water supply inlet as possible.
4. An inline water filter is highly recommended. It should be installed after the water
shutoff valve and in a position to facilitate filter replacement.
5. Flush the water supply line and filter before connecting it to the unit.
6. Verify that the water line provides at least 1½ gpm (5.7lpm), and that the water
pressure is between 40-75 psig (276-517kPa).
Electrical Connection
1. Check serial number plate for the maximum wattage and verify that the actual
voltage at the electrical outlet is compatible with the unit’s specifications.
2. Plug unit in. Note that the plug is NEMA 5-15P or NEMA 5-20P (domestic).
3. 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 is filled enough to
cover the heating element
WARNING-Do not plug in this equipment or attempt to operate without all covers in place and all screws fastened.

Final Setup-Fill and Initial Heating
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).
Screen one-the FETCO Home Screen will display.
4. Within 6 seconds, the water tank will begin filling until tank probe senses water
Screen two, the “FILLING” will display.
5. Water will cover heating element or when tank water is heating from cold,
Screen three-the “HEATING” Screen will display.
The upper and lower “Touch Function Selector” will not light.
6. After the water has reached the lowest of the four set temperatures, the lower
“Touch Function Selector” will light red color to signal that at least one
temperature range is READY
(The touch selector buttons will alternately dim and brighten when selection is not active)
7. The display will read the four temperature settings as the tank temperature
rises. More detailed operation information follows
8. The upper “Touch Function Selector” will light if one or more temperature level
is available during heating
9. Re- inspect for leaks.
Operating Instructions
1. Turn the main power switch on.
2. Touch the upper “Touch Function Selector”, tapping finger to scroll to select
3. When a temperature is enlarged and brightened - that temperature is available.
Touch the lower red selector to dispense hot water.
4. Maximum continuous “ON” is fifteen (15) seconds in a single activating touch
5. Maximum dispense is approximately 20 ounce/600 milliliter.
Approximately three full 15 second batches may be dispensed in succession.
6. Unit returns to inactive “Enabled Screen” if no water is dispensed in 3 seconds
7. Steam and condensation from the water tank is released into the vent
whenever the unit is on. Access the vent barbed fitting located on the upper
back to run gravity drain. For venting to a drain, tubing requirement is ¼” I.D.
(To prevent vacuum backflow, do not place discharge end of vent drain tube
into drain sump)
Operator Training
Review the operating procedures with everyone who will be using the unit.
Pay particular attention to the following areas:
1. Selecting and dispensing water at all four levels
2. How to change temperature settings (See page 7)
3. Scrolling and selecting temperatures and operating the hot water faucet.
Pay particular attention to the safety warnings. (See page 6 & 7)
4. Refer to cleaning procedures and drip tray, listed on the following page.
5. Show the location of the on/off switch, water shut off valve and the utility power
supply circuit breaker for the unit. (See page 3)

Operating Principles
The dispense valve assembly mixes very hot tank water with cooler water to deliver precision temperature water
at selected temperatures.
When hot water is drawn from the faucet, the fill valve pulses on and off every few seconds to replenish the tank.
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 screen will show that the
temperature is not available.
If hot water tank supply is depleted during high use, faucet will temporary “lockout” to allow the hot water tank to
reheat for an adequate hot water supply. The “HEATING” screen will display at this time.
Cleaning & Maintenance
Daily:
•Check the drip tray and empty if necessary. An indicator pop-up center button rises when full.
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
Notice:
•Turn off power to the HWD-2105 before any cleaning procedure, including wiping the exterior for
appearance reasons. Dry the exterior, especially the face panel, before turning on power.
WARNING:
•Do not apply any type of spray cleaner on the face panel of this equipment.
•Never use any solvent based cleaner or polish on this equipment.
•Dry the face of the HWD-2105 before turning on power.
•WARNING-Do not energize this equipment or attempt to operate without all covers in place and all
screws fastened.
Tank Drain
The water tank must be drained before maintenance procedures, and when 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 large enough to hold four gallons of water.
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.
