Model

Amount of Cleaner

IF0600C/IBF0620C/IBF0820C

IF0900C/IBT1020C/IT1200C

4. Close and secure the front door. The ice machine will

automatically start ice making after the descale cycle

is complete (approximately 24 minutes).

NOTE: Once the cycle has started it must complete before

the ice machine can make ice again. Returning it to ice

making mode will not cancel a clean cycle
