ELECTRICAL REQUIREMENTS
Refer to Data Plate on the dispenser, and local/national electrical code 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 120V LCC-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.
The LCC-2A LP dispenser is supplied with a 230-volt / 16 Amp cord set.
The 208-240V LCC-2 LP dispenser is not supplied with a cord set. It requires a 2-wire, grounded, individual
branch circuit rated for 208-240 volts AC, 20 amp, single phase, 60Hz.
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.
INTRODUCTION
The Liquid Coffee Chilled 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.
BUNN recommends the use of our Easy Clear®Water Quality Systems to assure perfect taste.

REPLACING THE PUMP TUBING
The pumps and tubing used in the dispenser are designed to give maximum performance and long life. However,
the tubes are a wear item and must be replaced periodically. How long the tubes last is dependent on usage and
properties of the concentrate. Excessive wear will reduce the output of the pumps resulting in a weak mixed
beverage. Bunn-O-Matic recommends replacing the Pump Tubing a minimum of once every 6 months or sooner
if warranted.
Refer to the Tube Replacement Instruction inside the Cabinet door.
Note: To avoid concentrate spills, rinse the pump tubing with warm tap water prior to removing the tubes, (Refer
to steps 1 - 4 of the Weekly Sanitizing instructions).
1. Loosen the thumbscrew (Fig 1) securing the tubing retainer plate to the pump body and set the retainer plate
aside.
2. Depress the tension screw and remove it from the notch in the pump body, releasing the spring tension on
the pump band (Fig 2).
3. Gently pull the pump tube from around the pump rotor (Fig 3).
4. Inspect the pump bands, rollers and housing for contamination or signs of wear. Clean or replace worn parts
if necessary.
5. Apply lubricant (BUNN-O-MATIC part no. M2531.0001) to the middle section of the new pump tubing (Fig
4).
6. Carefully wrap the new tubing around the rotor, making sure that the elbow and clamps end up on the front
side of the pump body (Fig 5).
7. Depress the tension screw and insert it in the notch in the pump body, reapplying spring tension on the pump
band.
8. Install the free end of the tube over the inlet port of the mix chamber on that side of the cabinet (Fig. 5).
9. Replace the tubing retainer plate and tighten the thumbscrew.
9. Open the product container and insert the stainless steel drawtube into the container (Fig 6).
10. Repeat steps 1 through 9 for the other pump.
Note: Replacement Tube Kits can be purchased from BUNN-O-MATIC. Order part no. 37942.1000
