Periodically, you should clean and descale the brewer to clear any mineral deposits that may have accumulated due to impurities in the water source. If these deposits are not removed, they can impair the operation of the brewer and reduce the product life.
There are several products available specifically for descaling. We recommend using URNEX® Activated Descaler or JavaClean2 Cleaner and Descaler, available on our web site: www.bunn.com. (White vinegar can be used to descale if a descaling product is not available.)
Follow the directions as printed on the manufacturer’s package.
NOTE: There is now descaling solution in the internal tank. Follow the manufacturer’s directions if the solution must be left in the tank for any period of time. For vinegar, allow the solution to sit for at least two, but no more than four hours.
CLEANING THE SPRAYHEAD/SEAL
NOTE: If the sprayhead and seal are separated, they must be reassembled as they were when removed from the brewer. Improper reassembly could result in personal injury from scalding water.
ASSEMBLING THE SPRAYHEAD/SEAL
If the sprayhead and seal are separated during removal or cleaning, they must be reassembled properly.
When properly assembled, the sprayhead will slide easily into the channel of the seal and will not cause any buckles in the surface of the seal. If the sprayhead seems to be difficult to seat, and you must stretch the seal more than a slight tug, the assembly is not together correctly.
INSPECTING THE SPRAYHEAD SEAL
When disassembling your brewer for cleaning, inspect the sprayhead seal for cracks, tears and holes. Although the seal should last for an extended period of time, damage can occur through handling.
CAUTION: The seal confines the hot liquid to the pod holder. Replace the seal if it becomes damaged. Parts are available at www.bunn.com.
CLEANING THE POD HOLDER
To prevent residue build up, it is a good idea to periodically disassemble the pod holder/screen assembly and clean it with a mild detergent.
WARNING: Brewing without the insert can result in hot liquid splash and burns.
CYCLING THE BREWER
If the brewer has not been used for an extended period of time, it is a good idea to cycle your brewer before brewing a serving of coffee or tea.
CAUTION: Water is hot!
STORING THE BREWER
NOTE: Water will remain in the internal tank. If stored for an extended period of time, refer to “Cycling The Brewer” section before using.
