3. Return it to its original position.
Do not operate the machine without the filter in
place except during cleaning.
Air cooled condenser
If the machine has been operated without a filter
the air cooled condenser fins will need to be
cleaned.
They are located under the fan blades. The
services of a refrigeration technician will be
required to clean the condenser.
Exterior Panels
Fingerprints, dust and grease build up on the
panels will require occasional cleaning.
Water filters
If the machine has been connected to water filters,
check the cartridges for the date they were
replaced or for the pressure on the gauge. Change
cartridges if they’ve been installed more than 6
months or if the pressure drops too much when the
ice machine fills with water.
