ELECTRICAL REQUIREMENTS

L2 RED

L1 BLACK

200, 230 or

240V A.C.

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 respectively, 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.

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.

MODEL OL25B requires 2-wire, grounded service rated 100 volts ac, 20 amp single phase, 50 Hz.

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-OMatic 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.

This equipment must be installed to comply with the International Plumbing Code of the International Code Council and the Food Code Manual of the Food and Drug Administration (FDA). For models installed outside the U.S., you must comply with the applicable Plumbing/Sanitation Code for your area.

PLUMBING REQUIREMENTS (Cont.)

Plumbing Hook-Up

Model OL15 has an attached water strainer, proceed to step 2. Models OL20, OL35, & RL35, proceed as follows:

1. Remove the rear panel and bottom pan. Run the long piece of tubing from the strainer (supplied) under the brewer and attach it to the water inlet ﬁtting on the bottom bracket. Reinstall the bottom pan and rear panel.

2. Flush the water line and securely attach it to the 1/4” ﬂare ﬁtting on the strainer.

3. Turn on the water supply.

INITIAL SETUP

CAUTION - The brewer must be disconnected from the power source throughout the initial setup, except when

speciﬁed in the instructions.

1. Remove the top panel.

2. Rotate the control thermostat knob fully counterclockwise to the “OFF” position and replace the panel.

3. Insert an empty funnel into the funnel rails.

4. Place a decanter containing a small amount of water on the warmer beneath the funnel.

5. Connect the brewer to the power source, place the On/Off brew station warmer switch the upper position, and momentarily press the start switch. Water will begin ﬂowing into the tank. When water stops ﬂowing into the tank, initiate a second and a third brew cycle. During this third brew cycle the tank will ﬁll to its capacity and the excess will ﬂow from the sprayhead, out of the funnel, and into the decanter.

NOTE - The On/Off brew station warmer switch must be in the upper position to initiate and complete a brew cycle.

6. Place the On/Off brew station warmer switch in the lower position.

7. Disconnect the brewer from the power source.

8. Remove the top panel.

9. Rotate the control thermostat knob fully clockwise to the “ON” position and replace the panel.

10. Connect the brewer to the power source and wait approximately twenty minutes for the water in the tank to heat to the proper temperature. Some water will drip from the funnel during this time; this is due to expansion and should not occur thereafter.

11. Place an empty decanter under the funnel.

12. Place the On/Off brew station warmer switch in the upper position and momentarily press the start switch. Empty the decanter after water has stopped ﬂowing from the funnel.

13. Allow the water in the tank to reheat to the proper temperature.

14. Place an empty decanter on the warmer and press the start switch. Check the water volume in the decanter after water has stopped ﬂowing from the funnel. It should be 64 ounces.

15. If not, disconnect the brewer from the power source and remove the top panel.

16. Add or remove washers to the ﬂoat on the level switch as required. Adding washers increases the volume, removing washers decreases it. Replace the top panel, connect the brewer to the power source, start, and measure another brew cycle.

17. Repeat steps 13-16 until 64 oz water volume is achieved.

COFFEE BREWING

Start each brew cycle with an empty, clean, half-gallon decanter.

1. Insert a BUNN® ﬁlter into the funnel.

2. Pour the fresh coffee into the ﬁlter and level the bed of grounds by gently shaking.

3. Slide the funnel into the funnel rails.

4. Place the On/Off brew station warmer switch in the upper position.

5. Momentarily press the start switch.

6. When brewing is completed, simply discard the grounds and ﬁlter.

CLEANING

1. The use of a damp cloth rinsed in any mild, non-abrasive, liquid detergent is recommended for cleaning all surfaces on Bunn-O-Matic equipment.

2. Check and clean the sprayhead. The sprayhead holes must always remain open.

3. With the sprayhead removed, insert the deliming spring (provided) all the way into the sprayhead tube. When inserted properly, no more than two inches of spring should be visible. Saw back and forth ﬁve or six times.

NOTE - In hard water areas, this may need to be done daily. It will help prevent liming problems in the brewer and takes less than a minute.
