INTRODUCTION

NOTE: Information in this publication applies to dispensers with software version LC-1.41 and up.

The Liquid Coffee Ambient Dispenser delivers two types of coffee plus hot water. The dispenser can be set up for continuous draw (by the cup) for self-serve applications, or portion-control to ﬁll carafes and decanters for wait staff.

ELECTRICAL REQUIREMENTS

WARNING - If the power cord is ever damaged, it must be replaced by the manufacturer or its service agent with

a special cord available from the manufacturer or its service agent in order to avoid a hazard.

The LCA-2 LP dispenser is 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 515R.

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 3/8” 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 1/4” ﬂare. Dispensers set up to deliver to 47.3 ml/sec (1.6 Oz./sec.) and require a water supply source that can deliver a minimum of 1.7 gpm (6.4 lpm) at the inlet ﬁtting. NOTE: Bunn-O-Matic recommends 1/4” tubing from the 3/8” 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). For models installed outside the

U.S.A., you must comply with the applicable Plumbing/Sanitation Code for your area.

BUNN recommends the use of our Easy Clear® Water Quality Systems to assure perfect taste.
