BUNN | TB3, 29" Trunk - Daily Cleaning Instructions

Remove, disassemble and thoroughly clean and sanitize the entire brew funnel. The funnel tip and screen must be free from any tea particles or residue. Reassemble the funnel.
Place the ON/OFF switch in the "OFF" position. 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.
Insert the deliming spring into the sprayhead fitting until no more than two inches is visible and move it in and out 5 or 6 times. Reattach the sprayhead.
Wash the entire outside surface of the brewer (including the sprayhead panel) with a clean damp cloth.

Remove the connector off of the bag in a box
Place the end in a bucket of hot water (120°-130°F)
Place an empty reservoir on the base under the dilution nozzle.
Set the selector switch to the "Sweetened" setting.
Press and release the "Start" switch.
Run three brew cycles in a row, emptying the reservoir after each cycle.
When the three cycles have been completed, hook the connector back up to the bag in a box system. (This will keep buildup from occurring in the system.)
