All of the critical functions of the brewer are electronically controlled.

SITE REQUIREMENTS

ES•2C

PHYSICAL

The brewer is for indoor use only on a sturdy counter. It is 2612” (67 cm) wide,16” (40.5 cm) tall, and 1912” (49 cm) deep. The brewer weighs approximately 142 pounds (64.5 kg) when the water tank is filled.

PLUMBING

The brewer must be connected to a cold water source with operating pressure between 20 and 90 psi (1.5- 6.5 bar) from a 12” or larger supply line. Install a valve in the water line before the brewer. Install a regulator before the brewer when the pressure is greater than 100 psi (7 bar) to reduce it to 45-60 psi ( 3-4 bar). The enclosed water strainer and either of the two enclosed water inlet hose assemblies must be installed before the brewer.

NOTE-Only softened or demineralized water should ever be used in this espresso brewer to reduce the service problems caused by naturally occuring elements in your local water supply. A polyphosphate feeder is not recommended because it does not remove minerals.

NOTE-Bunn-O-Matic recommends 38” copper tubing for no more than 25 feet from the 12” water supply line. Bunn-O-Matic does not recommentd the use of a saddle valve to install the brewer. The size and shape of the hole made in the supply line by this type of device may restrict water flow.

ELECTRICAL

The brewer is equipped with an attached cordset and requires a 2-wire, grounded mating receptacle rated 208-240 volts ac, 20 amp, single phase, 60 Hz. An electrician must properly install a NEMA L6-20R connector to the appropriate electrical service on an individual branch circuit to install this brewer.

CAUTION-The brewer must be properly grounded. A plumbing line will not provide an adequate ground.

ELECTRICAL

CAUTION-The brewer must be disconnected from the power source until specified. Improper electrical installation will damage electronic components.

1.Using a voltmeter, check the voltage and color coding of each conductor at the electrical source.

2.When instructed to proceed, connect the brewer to the power source.

CAUTION-The brewer must be properly grounded. A plumbing line will not provide an adequate ground.

INITIAL FILL & HEAT

CAUTION-The brewer must be disconnected from the power source until specified. Improper electrical installation will damage electronic components. Plumbing must be connected to the brewer before proceeding.

1.Watch the tank water level gage and push the tank/boiler manual fill button. Hold the button until the water level is visible in the sight gage.

2.Connect the brewer to the power source.

3.Place the main power switch in the “ON” position. The automatic refill function of the electronic control system will engage at this time. The refill indicator will glow and the tank will automatically fill with water. This switch also initiates the heating of the water in the tank/boiler.

4.Press the continuous flow button on each of the group control panels just until water flows from the group heads. This will purge air from the lines and allow faster heating of the group heads.
