Bunn 39130.0000J service manual Plumbing Requirements, Initial SET-UP

PLUMBING REQUIREMENTS

These brewers 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 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.

As directed in the International Plumbing Code of the International Code Council and the Food Code Manual of the Food and Drug Administration (FDA), this equipment must be installed with adequate backflow pre- vention to comply with federal, state and local codes. For models installed outside the U.S.A., you must comply with the applicable Plumbing /Sanitation Code for your area.

1.Flush the water line and securely attach it to the inlet fitting at the rear of the brewer.

2.Turn on the water supply.

INITIAL SET-UP

1.Insert an empty funnel into the funnel rails.

2.Place an empty server under the funnel.

3.Connect the brewer to the power source.

4.Turn on the main ON/OFF switch located on the left side of brewer (If equipped).

5.Water will flow into the tank and stop when the tank is filled to its capacity. Display will show "PLEASE WAIT...TANK FILLING" until tank is filled with water.

6.Wait approximately twenty minutes for the water in the tank to heat to the proper temperature. Display will show "READY TO BREW...WATER TEMP: 200°" when tank is at operating tempera- ture. Some water will drip from the funnel during this time; this is due to expansion and should not occur thereafter.

7.Place a small container beneath the faucet and open the faucet handle. Release it when you hear the tank refilling.

8.Water volumes and flow settings have been preset at the factory. Refer to adjustments for the Set Brew Volumes section of this manual should the volume need to be increased or decreased.

9.The brewer is now ready for use in accordance with the instructions for Coffee Brewing.

10.Repeat steps 5-9 for remaining side on Twins.

If setting up new brewer in high mineral locations, refer to programming (Enable Brew Logic). Pertains to units with software version 1.06 & up.

Brew water temperature is factory set at 200ο F (93.3ο C) Areas of high altitude will require lowering this tempera- ture to prevent boiling. This chart should be used as a guide when readjusting the brew water temperature.
