Maintenance

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.
,
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.

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.
