Step 1 Open the front door to access the evaporator
compartment. Ice must not be on the evaporator during
the clean/sanitize cycle. Follow one of the methods below:
• Press the power switch at the end of a harvest cycle
after ice falls from the evaporator(s).
• Press the power switch and allow the ice to melt
• Use the touchscreen to initiate a manual harvest cycle.
Notice
Never use anything to force ice from the evaporator.
Damage may result.
Step 2 Remove all ice from the bin/dispenser.
Step 3 Press the Clean button and select “Turn off
when complete”. Water will flow through the water dump
valve and down the drain. Wait approximately 1 minute
until the water trough refills and the display indicates Add
Chemical. Add the proper amount of ice machine cleaner/
descaler to the water trough by pouring between the
water curtain and evaporator, then confirm the chemical
was added.
NOTE: There is a 10 minute time limit to confirm chemical
was added.
• Confirmation is pushed within 10 minutes - The ice
machine will start a 10 minute wash cycle, followed by
6 rinse and flush cycles.
• Confirmation is not pushed within 10 minutes - The ice
machine will skip the 10 minute wash cycle and start 6
rinse and flush cycles.
Model Amount of Cleaner/Descaler
IF0300/IT0300/IT0420/IT0620 3 ounces (90 ml)
IT0450/IF0500/IT0500/IF0600
IT0750/IF0900/IT0900/IT1200
5 ounces (150 ml)
IT1500/IT1900 9 ounces (265 ml)
