ELECTRICAL REQUIREMENTS
CAUTION - The brewer must be disconnected from the power source until specified in
Initial Set-Up.
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 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 brewer using a junction box.
5. Connect the brewer to the power source and verify the voltage at the terminal block before proceeding. Replace
all panels.
6. If plumbing is to be hooked up later be sure the brewer is disconnected from the power source. If plumbing
has been hooked up, the brewer is ready for
Initial Setup
.
NOTE: A schematic wiring diagram is included in this manual.
PLUMBING REQUIREMENTS
The brewer must be connected to a cold water system 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 brewer.
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.
NOTE - Bunn-O-Matic recommends 3/8" copper tubing for installations from the 1/2" water supply line. Bunn-O-
Matic does not recommend the use of a saddle valve to install the brewer. The size and shape of the hole made
in the supply line by this type of device may restrict water flow.
PLUMBING HOOK-UP
1. Make certain the 3/8" female flare fittings on the tube (supplied) are securely attached to the strainer outlet and
male fitting at the rear of the brewer.
2. Flush water line and securely attach it to the 3/8" male flare on the inlet of the strainer.
Requires 2-wire, gorunded service rated 230 volts
ac, 32 Amps, single phase, 50 Hz.
