*Full Batch

*If BREW is pressed with a large grinder batch, the display will read: INCORRECT GRIND...BATCH SIZE WRONG, and then PRESS BREW TO BREW ANYWAY.

5.Place an empty server under the funnel.

6.The ON/OFF must be ON.

7.Momentarily press and release the assigned BREW button. There may be certain situations in which the brew cycle will not begin when BREW is pressed:

a.SWITCH NOT ON - ON/OFF must be ON.

b.BREW TEMPERATURE TOO LOW – wait until heated or cancel BREW LOCKOUT option (Page 17).

c.CHECK FUNNEL – remove funnel, empty previously brewed grounds and replace with fresh.

d.INCORRECT GRIND - Indicates a large batch was ground using the grinder. Check batch size and grind weight.

8.If none of the above messages are displayed, the display will read NOW BREWING and show the time remain- ing in the brew cycle.

9.Following the brew will be a countdown of drip time DRIPPING which shows the time remaining until the coffee no longer drips from the funnel tip.

10.Carefully remove the brew funnel and discard the grounds and filter only after visible dripping stops.

CLEANING

CAUTION – CLEAN AND SANITIZE YOUR ICED TEA BREWER DAILY

1.Remove and thoroughly clean the entire brew funnel. The funnel tip and screen must be free from any tea particles or residue. Reassemble the funnel.

2.Remove and thoroughly rinse the sprayhead. The holes must be open and clear of any mineral deposits. Wipe the sprayhead panel clean with a damp cloth.

NOTE – Any buildup on the sprayhead may restrict water flow, and impact yuor brewing. For consistently great tea and coffee, clean sprayhead weekly with sprayhead cleaning tool (#38227.0000). Upon visual inspection it may appear that light passes through all holes in the sprayhead, but a thin film of residue can pass light and still impede water flow.

a.Remove sprayhead from brewer.

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

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

3.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.

CAUTION – DO NOT KEEP BREWED ICED TEA OVERNIGHT. THE SERVER MUST BE CLEANED DAILY.

See page 50 of instruction manual for calibration routine to verify sprayhead flow rate matches programmed flow rate. Brewer may need to be re-calibrated due to lime build up. If brewer is cleaned and build up removed, brewer must be re-calibrated to achieve desired volumes.
