INTRODUCTION

The BUNN LCA-1 dispenser is design to hold up to 1/2 gal (2 l) of ambient - shelf stable liquid coffee concentrate. The BUNN LCR-1 also holds up to 1/2 gal (2 l) of refrigerated liquid coffee concentrate. Both dispensers are designed to operate when ambient temperatures are from 32°F (0°C) minimum to 95°F (35°C) maximum. Always follow the Concentrate Manufacturer’s Storage and Shelf Life recommendations.

ELECTRICAL REQUIREMENTS

Refer to the Data Plate on the dispenser, and local/national electrical codes to determine circuit 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-1 & LCR-1 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-1C & LCR-1C 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.

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. The dispensers set up to deliver to 37.0 ml/sec (1.25 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. 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 International Plumbing Code of the International Code Council and the Food Code 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.

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.

INITIAL SET-UP

NOTE: The LCA-1 weighs approximately 40 lbs. (18 kg) and the LCR-1 weighs approximately 55 lbs. (25 kg), when empty.

If necessary, use more than one person when lifting or moving the dispenser.

1.Cut the plastic bands and remove the top box and other packing.

2.Locate and remove the Adapter Tube Kit, Graphic Kit, Drip Tray & Literature Pkg from the packaging and set aside.

3.Set dispenser on the counter where it is to be used. CAUTION: DO NOT LIFT ON THE DOOR.

4.Install the drip tray assembly between the front legs. The magnets will hold the tray in place.

5.Install the Graphic decal in the door.

LOCATING THE DISPENSER

Additional clearance is required on both sides and behind the dispenser to allow for proper air flow and cooling. The LCA-1 requires a minimum space of 16.6” wide x 17.8” tall x 23.0” deep (to allow for the drip tray, water and electrical connections). The LCR-1 requires a minimum space of 17.1” wide x 17.8” tall x 26.0” deep (to allow for the drip tray, water and electrical connections). In addition, allow enough clearance on the left-hand side to allow the door to open freely.

NOTE: In high ambient location where the air temperature around the dispenser could exceed 95°F (35°C), additional clearance is required on both sides and behind the dispenser to allow for proper air flow and cooling. For these higher temperature locations, the total space required for the LCA-1 is 16.6” wide x 17.8” tall x 23.0” deep, and 17.1” wide x 17.8” tall x 26.0” deep for the LCR-1.

PLUMBING HOOK-UP

1.Flush the water line to remove any debris or foreign material.

2.Remove the shipping cap from the inlet fitting on the back of the dispenser and securely attach the water line to the fitting supplied.

3.Turn on the water supply and check for leaks.

ELECTRICAL HOOK-UP

CAUTION: Improper electrical installation will damage electronic components.

Refer to Data Plate on the dispenser, and local/national electrical codes to determine circuit requirements.

1.An electrician must provide electrical service as specified in conformance with all local, state and federal electrical codes.

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

3.Connect the dispenser to the power source.

4.If plumbing is to be hooked up later, be sure the dispenser is disconnected from the power source. If plumbing has been hooked up, the dispenser is ready for Initial Fill & Heat.
