CAUTION: Power to brewer must be OFF	I: 1
before proceeding with plumbing installation.

1.Flush water line before installing brewer. Brewer should be connected on Cold Water Line for best operation.

2.Water pressure should be at least 20 Ibs. For less than a 25 ft. run, use 1/4" copper tubing from 1/2" or larger water line_ For more than a 25 ft. run, use 3/8" copper tubing from 1/2" or larger water line, and provide an adapter fit- ting for conne.ction to the water strainer.

3.Connect incoming water line to the incoming

male fitting on the strainer.

A SHUT OFF VALVE SHOULD BE INSTALLED ON THE INCOMING WATER LINE IN A CON- VENIENT LOCATION.

NOTE: The National Sanitation Foundation requests a provision be made in the incoming water line for flexibility. This is necessary to allow tilting or moving the brewer for proper cleaning underneath, etc. A tightly coiled length of copper tubing located ahead of the water strainer would help comply with this request.
