ELECTRICAL REQUIREMENTS

CAUTION: The dispenser must remain disconnected from power source until specified in Electrical Hook-Up.

The LCR-2 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 LCR-2C dispenser is 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.

These dispensers can be Field Wired for 208 or 240 volt applications. This requires a 2 or 3-wire, grounded, individual

branch circuit rated for 208/240 volts AC, 30 amp, single phase, 60 Hz.

NOTE: The internal terminal block must be rewired for 208/240 applications, (see Optional Field Wiring Diagram).
