INTRODUCTION

The Liquid Coffee Ambient Dispenser delivers two types of coffee made from liquid concentrate 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. Follow the Concentrate Manufacturer’s Storage and Shelf Life recommendations.

This dispenser is designed to operate when ambient temperatures are from 32°F (0°C) minimum to 104°F (40°C) maximum.

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 5- 15R.

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 50.0 ml/sec (1.7 Oz./sec.) and require a water supply source that can deliver a minimum of 1.0 gpm (3.8 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.

As directed in the International Plumbing Code of the International Code Council and the Food Code Manual of the Food and Drug Administration (FDA), this equipment must be installed with adequate backflow prevention to comply with federal, state and local codes. For models installed outside the U.S.A., you must comply with the applicable Plumbing /Sanitation Code for your area.

NOTE - Water pipe connections and fixtures directly connected to a potable water supply shall be sized, installed and maintained in accordance with federal, state and local codes.

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