PREVENTATIVE MAINTENANCE CLEANING
This cleaning procedure can be performed between the bi-
annual cleaning and sanitizing cycles. This procedure does 
not require removing the ice from the bin.
Step 1  Press the On/Off button after ice falls from the 
evaporator at the end of a Harvest cycle. Or, press the On/
Off button and allow the ice to melt off the evaporator.
,
Caution
Never use anything to force ice from the evaporator. 
Damage may result.
Step 2  To start a cleaning cycle, press the Clean button. 
Water will flow through the water dump valve and down 
the drain. Wait until the water trough refills, then add the 
proper amount of ice machine cleaner to the water trough.
Model Amount of Cleaner
U0140 2 ounce (60 ml)
U0190 5 ounces (150 ml)
U0240 5 ounces (150 ml)
U0310 5 ounces (150 ml)
Wait until the clean cycle is complete (approximately 22 
minutes) then press the On/Off button.
ICE MACHINE INSPECTION
Check all water fittings and lines for leaks. Also, make sure 
the refrigeration tubing is not rubbing or vibrating against 
other tubing, panels, etc.
Do not put anything (boxes, etc.) in front of the ice machine. 
There must be adequate airflow through and around the 
ice machine to maximize ice production and ensure long 
component life.
EXTERIOR CLEANING
Clean the area around the ice machine as often as necessary 
to maintain cleanliness and efficient operation.
Sponge any dust and dirt off the outside of the ice machine 
with mild soap and water. Wipe dry with a clean, soft cloth.
Clean up any fallen ice or water spills as they occur.
CLEANING THE CONDENSER
A dirty condenser restricts airflow, resulting in excessively 
high operating temperatures. This reduces ice production 
and shortens component life.
•  Clean the condenser at least every six months.
•  Shine a flashlight through the condenser to check for 
dirt between the fins.
•  Blow compressed air from the inside out (opposite 
direction of airflow).
•  If dirt still remains, call a service agent to clean the 
condenser.
Removal from Service/Winterization
Step 1  Clean and sanitize the ice machine.
Step 2  Press the On/Off button to turn off the ice 
machine.
Step 3  Turn off the water supply, disconnect and drain 
the incoming ice-making water line at the rear of the ice 
machine, and drain the water trough.
Step 4  Energize the ice machine, wait one minute for the 
water inlet valve to open, and blow compressed air in both 
the incoming water and the drain openings in the rear of 
the ice machine to remove all water.
Step 5  Press the On/Off button and disconnect the 
electric power at the circuit breaker or the electric service 
switch.
Step 6  Fill spray bottle with sanitizer and spray all interior 
food zone surfaces. Do not rinse and allow to air dry.
Step 7  Replace all panels.
