Bunn CWTF, CT service manual Cleaning

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. Use care when cleaning around the heater switch with a cloth, so as not to accidentally turn off the tank heater!

2.Clean out the sprayhead holes. A properly cleaned sprayhead will leave a dimple in the bed of coffee grounds for each hole. Example: 6 holes = 6 dimples. FIG 15-1/2

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. FIG 15-3. 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.

4.The faucet aerator may be removed for cleaning. Unscrew aerator assembly (counterclockwise from bottom) FIG 15-5

WARNING: DO NOT ATTEMPT TO DISASSEMBLE REMAINDER OF FAUCET ASSEMBLY UNTIL BREWER IS DISCONECTED FROM WATER LINE.
