Bunn ICBC, ICBA, ICBB service manual Cleaning

CLEANING

1.The use of a damp cloth rinsed in any mild, nonabrasive, liquid detergent is recommended for cleaning all surfaces on Bunn-O-Matic equipment. Do NOT clean this equipment with a water jet device.

2.Check and clean each sprayhead. The sprayhead holes must always remain open.

NOTE - Any buildup on the sprayhead may restrict water flow, and impact your coffee brewing. For consis- tently great coffee, clean sprayheads weekly. Upon visual inspection it may appear that light passes through all holes in the sprayhead plate, but a thin film of residue can pass light and still impede water flow.

3.Remove sprayhead from brewer. Disassemble by removing the seal.

4.Use the pointed end of sprayhead cleaning tool to remove any mineral deposits from the sprayhead holes.

5.Insert the long end of sprayhead cleaning tool into the sprayhead fitting, and rotate several times to remove any mineral deposits from the fitting.

6.Insert the short end of sprayhead cleaning tool into the bypass fittings, and rotate several times to remove any mineral deposits from the fitting.

7.Reassemble sprayhead and reattach. Sprayhead only needs to be hand tightened.

Refer to programming manual for calibration routine to verify sprayhead flow rate matches programmed flow rate. Machine may need to be re-calibrated due to lime build up. If machine is cleaned and build up removed, machine must be re-calibrated to achieve desired volumes.
