SITE REQUIREMENTS

ES•2C™

PHYSICAL

The brewer is for indoor use only on a sturdy counter. It is 261⁄2” (67 cm) wide,16” (40.5 cm) tall, and 191⁄2”

(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-

6.5bar) from a 1⁄2” 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 3⁄8” copper tubing for no more than 25 feet from the 1⁄2” 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.
