ELECTRICAL REQUIREMENTS
CAUTION - Do not connect the brewer to the power source until specified in Initial Set-Up.
MODELS OL15 & 20 require
2-wire, grounded service rated
120 volts ac, 15 or 20 amp re-
spectively, single phase, 60 Hz.
MODELS OL35 & RL35 require
3-wire, grounded service rated
120/208 or 120/240 volts ac, 20
amp, single phase, 60 Hz.
Electrical Hook-Up
Model OL15 has an attached cordset.
Models OL20, OL35, & RL35, proceed as follows:
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.
Remove the top panel and rotate the control
thermostat knob fully counterclockwise to the
“OFF” position and replace the panel.
4.
Remove the rear panel, feed the cord through
the strain relief, and connect it to the terminal
block.
5.
Connect the brewer to the power source and
verify the voltage at the terminal block before
proceeding. Replace the rear panel.
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 Set-Up.
PLUMBING REQUIREMENTS
This brewer must be connected to a cold water
system with operating pressure between 20 and 90
psi 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 to reduce it to 50 psi. The water inlet fitting is
1/4” flare.
NOTE - Bunn-O-Matic recommends 1/4” copper tubing
for installations of less than 25 feet and 3/8” for more
than 25 feet from the 1/2” water supply line. A tight
coil of copper tubing in the water line will facilitate
moving the brewer to clean the counter top. 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.
MODELS OLA, RLA, OL35B &
RL35B require 2-wire, ground-
ed service rated 240 volts ac
or 200 volts ac, 20 amp single
phase, 50 Hz.
P1478
MODEL OL25B requires
2-wire, grounded service
rated 100 volts ac, 20 amp
single phase, 50 Hz.
