Installation

(For Qualified Service Technicians Only)

Keys To A Successful Installation

FETCO dispensers are rugged and reliable machines that will provide many years of service. However, if not installed correctly by qualified personnel, the unit will 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 dispensers require NEUTRAL. Ground is not an acceptable substitute. Installation

without neutral will almost certainly cause damage to the electronic components.

The power connection to L1 on the terminal block must be at least 105 volts. Less than 105 volts will cause

erratic behavior.

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 dispenser is located on the inside of the 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 dispenser to prevent debris from

contaminating the machine.

Verify that the water line will provide at least 2 gallons per minute before connecting it to the dispenser.

General: Utilize a qualified beverage equipment service technician for installation.

Do not adjust the thermostat settings unless absolutely necessary. They are set at the factory for optimum

performance.

Installation Check List

The installation must comply with applicable federal, state, and local codes having jurisdiction at your location. Check

with your local inspectors to determine what codes will apply to the installation and operation of FETCO products.

1. Review the Dimensional Drawings (page 5) and the Operating Procedures (page 6) for the unit you are installing.

Verify the dispenser will fit in the space intended for it. Verify that the counter or table will support the weight of the dispenser when filled.

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

dispenser’s serial number plate. Make sure the electrical service includes neutral. Refer to the "Electrical Configurations " section, (page 3) to determine how the dispenser will perform on other voltages. Ensure at this time that the circuit breaker to the dispenser and the power switch on the dispenser are in the off position

3. The thermostat and the 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 liquid level control board until water is sensed. The heating process will start automatically when the tank has filled with water

5. Place the dispenser on a suitable counter or stand, ensuring it is strong enough. Refer to the dispenser weights

and capacities chart (page 2) for dry and wet weights.

6. When the dispenser is in position for use, level the dispenser front to back as well as side to side by adjusting

the feet.

Remove the cover.

Water connection:

• Water inlet is a 3/8 inch compression fitting on HWB-25, 1/4 inch compression fitting on all other models.

• The dispenser can be connected to a cold or hot water line. Cold water is preferred for best flavor, but hot

water will allow for faster recovery times.

• Install a water shut off valve near the dispenser 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.

• Flush the water supply line and filter before connecting it to the dispenser.

• Verify that the water line will provide at least 2 gallons per minute and that the water pressure is between 20

and 75 psig.

• 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 installation has been completed.

10.

Vent tube connection:

• Vent tube connection is a 3/8 inch hose barb.

• The end of the vent tube should be open to the air, not connected or submerged.

11.

Power connection:

• A fused disconnect switch or circuit breaker on the incoming power line must be conveniently located near the dispenser, and its location and markings known to the operators.

• All dispensers require neutral. Damage to the dispenser may result if neutral is not present.

• The body of the dispenser must be grounded to a suitable building ground. A ground lug is provided in the

dispenser next to the power terminal block. Use only 10 gauge copper wire for grounding.

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