ELECTRICAL REQUIREMENTS
CAUTION - The brewer must be disconnected from the power source until specified in
Initial Set-Up.
U333 & U3833 requires 3-wire, grounded service
rated 240 volt ac, 35 amp or 440 volts ac, 30 amp for
U333,three phase, 60 Hz or 380 volts ac, 30 amp for
U3833, three phase, 50 Hz. Proceed as follows:
U3 & U38 requires 3-wire, grounded service rated
120/208 or 120/240 volts ac, U3-30 amp,U38-40 amp,
single phase, 60 Hz. Proceed as follows:
ELECTRICAL INSTALLATION INSTRUCTIONS
CAUTION – Improper electrical installation will damage electronic components.
1. An electrician must provide electrical service as specified.
2. Using a voltmeter, check the voltage and color coding of each conductor at the electrical source.
3. Before electrically connecting the brewer, remove the front cupola cover (some models have the thermostat knob
on the outside of the cover) and rotate the thermostat knob fully counterclockwise to the "OFF" position. Keep this
knob in the "OFF" position until performing the
Initial Setup
.
4. Electrical service is connected at the upper rear of the single service and scrambler brewers using a junction
box. On double service brewers the rear decorative channel must be removed for access to the terminal block.
5. Connect the brewer to the power source and verify the voltage at the terminal block before proceeding. Replace
all panels.
