ELECTRICAL REQUIREMENTS

CAUTION: The dispenser must remain disconnected from the power source until specified in Electrical Hook-Up.

The LCA-2 and LCC-2 dispensers are supplied with a 120-volt / 15 Amp cord set and require a 2-wire, grounded, individual branch circuit rated for 120 volts AC, 15 amp, single phase, 60Hz. The mating connector must be a NEMA 5-15R.

The LCA-2C and LCC-2C dispensers are supplied with a 120-volt / 20 Amp cord set and require a 2-wire, grounded, individual branch circuit rated for 120 volts AC, 20 amp, single phase, 60Hz. The mating connector must be a NEMA 5-20R.

These dispensers can be Field Wired for 208 or 240 volt applications. This requires a 2 or 3-wire, grounded, individual branch circuit rated for 208/240 volts AC, 30 amp, single phase, 60 Hz.

NOTE: The internal terminal block must be rewired for 208/240 applications, (see Optional Field Wiring Diagram).

PLUMBING REQUIREMENTS

The dispenser may be connected to a cold or hot water system (140°F Max.) with operating pressure between 20 and 90 psi (138 and 620 kPa) from a 1/2" or larger supply line. A shut-off valve should be installed in the line before the dispenser. Install a regulator in the line when pressure is greater than 90 psi (620 kPa) to reduce it to 50 psi (345 kPa). The water inlet fitting is 3/8" flare. Dispensers set up to deliver to 1.8 Oz./sec. (53.2 ml/sec) per dispense tip, require a water supply source that can deliver a minimum of 1.7 gpm (6.4 lpm) at the inlet fitting. Dispensers set up to deliver 2.6 Oz./sec. (76.9 lpm) per dispense tip, require a water supply source that can deliver a minimum of 2.4 gpm (9.2 lpm) at the inlet fitting.

NOTE: Bunn-O-Matic recommends 3/8" tubing from the 1/2" water supply line. At least 18 inches of FDA approved flexible beverage tubing, such as reinforced braided polyethylene or silicone, before the dispenser will facilitate movement to clean the counter top. It can be purchased direct from Bunn-O-Matic (part number 00326.0000). Bunn-O-Matic does not recommend the use of a saddle valve to install the dispenser. The size and shape of the hole made in the supply line by this type of device may restrict water flow.

This equipment must be installed to comply with the Basic Plumbing Code of the Building Officials and Code Administrators International, Inc. (BOCA) and the Food Service Sanitation Manual of the Food and Drug Administration (FDA).
