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.

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., 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).
