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. 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.
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.

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.
ELECTRICAL REQUIREMENTS (Cont.)
CAUTION: The dispenser must remain disconnected from power source until specified in Electrical Hook-Up.
The LCR-2A 3 Phase dispenser is internally wired from the factory for 400 Volts AC Phase to Phase, 230 Volts AC
Phase to Neutral, 3 Phase 50/60 Hz. It requires a 4-wire, grounded, individual branch circuit rated for 400 Volts AC,
Three Phase, 50/60 Hz. At Three Phase operation, each Phase will have approximately 13.5-14.0 Amps flow through
it.
The LCR-2A 3 Phase dispenser can be Field Wired for 230 Volts AC, Single Phase applications. This requires a 2-wire,
grounded, individual branch circuit rated for 230 volts AC, Single Phase, 50/60 Hz. At Single Phase operation, the
machine will have approximately 27.5 Amps flow through it.
NOTE: The internal terminal block must be rewired for 230 Volts AC, Single Phase applications, (see Optional Field Wiring
Diagram).
