ELECTRICAL REQUIREMENTS
CAUTION - The brewer must be disconnected from the power source until specified in Initial Set-Up.
Model 35 requires 3-wire,
grounded service rated 120/208
or 120/240 volts ac, 20 amp,
single phase, 60 Hz. Proceed as
follows:
Model 20 requires 2-wire,
grounded service rated 120 volts
ac, 20 amp, single phase, 60 Hz.
Proceed as follows:
Electrical Hook-Up
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. Place the heater switch at the rear of the brewer in the “OFF” lower position.
4. Remove the front panel beneath the sprayhead.
5. Feed the cord through the strain relief and connect it to the terminal block.
6. Connect the brewer to the power source and verify the voltage at the terminal block before proceeding. Re-
place the front panel.
7. 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 Set-Up.
“A" & "B” models require
2-wire, grounded service rated 200
volts ac or 240 volts ac, 20 amp,
single phase, 50 Hz. Proceed as

PLUMBING REQUIREMENTS
These brewers must be connected to a cold water system with operating pressure between 20 and 90 psi
(138 620 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
1
⁄
4
" flare.
NOTE - Bunn-O-Matic recommends
1
