PLUMBING REQUIREMENTS

These brewers must be connected to a cold water system with operating pressure between 20 (138) and 90 psi (620 kPa) from a 1Ú2" 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 1Ú4" flare.

NOTE - Bunn-O-Matic recommends 1Ú4" copper tubing for installations of less than 25 feet and 3Ú8" for more than 25 feet from the 1Ú2" water supply line. A tight coil of copper tubing in the water line will facilitate moving the brewer to clean the countertop. 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.

This equipment must be installed to comply with the Basic Plumbing Code of the

Building Officials and Code Administrators International, Inc. (BOCA)

and the Food Service Sanitation Manual of the Food and Drug Administration (FDA).

1. Remove the shipping cap from the bulkhead fitting on the rear of the brewer.

2. Attach the flare fitting from the short piece of tubing on the strainer/flow control (supplied) to the water inlet fitting at the rear of the brewer.

3. Flush the water line and securely attach it to the flare fitting on the strainer/ flow control.

4. Turn on the water supply.
