Cleaning & Tank Drain - Bunn Axiom BrewWISE Series Installation & Operating Manual

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.
2. Check and clean the sprayhead. The sprayhead holes must always remain open. Insert the short
end of the sprayhead cleaning tool into each of the five water outlets of the plastic sprayhead to
remove any mineral deposits (Refer to Fig 1)
3. Insert the long end of sprayhead cleaning tool into the sprayhead fitting, and rotate several times
to remove any mineral deposits from the fitting (Refer to Fig 2).
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.
NOTE: In the event that the "Brew Logic" circuit activates (compensating for high lime build up), it
will temporarily disable the "Recovery Booster" and "Pulse Brewing" systems until the unit has been
de-limed. Refer to the Troubleshooting section for more details.
