DELIMING

Bunn-O-Matic recommends deliming your coffee brewer periodically. The actual frequency of deliming de- pends on the mineral content of the water you use. 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.

Follow these simple steps:

1.Unplug the brewer and let it cool down before proceeding.

2.Remove the brew funnel.

3.Remove the sprayhead by turning it to the left with your fingertips and set it aside.

4.With the sprayhead removed, insert the deliming spring (pro- vided) 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. Remove the spring.

5.Check the holes in the sprayhead. If plugged by lime, they may be cleared using a toothpick. Rinse the sprayhead with water before reinstalling it.

6.Reinstall the sprayhead by turning it to the right.

7.Plug in the brewer and allow the water to reheat before using.

Remove sprayhead by turning counterclockwise
