AIR-COOLED 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. Follow the steps below.

WARNING

The condenser fins are sharp. Use care when cleaning them.

1.The washable aluminum filter on self-contained air-cooled ice machines is designed to catch dust, dirt, lint and grease. This helps keep the condenser clean. Clean the filter with a mild soap and water solution.

2.Clean the outside of the condenser with a soft brush or a vacuum with a brush attachment. Clean from top to bottom, not side to side. Be careful not to bend the condenser fins.

3.Shine a flashlight through the condenser to check for dirt between the fins. If dirt remains:

a)Blow compressed air through the condenser fins from the inside. Be careful not to bend the fan blades.

b)Use a commercial condenser coil cleaner. Follow the directions and cautions supplied with the cleaner.

4.Straighten any bent condenser fins with a fin comb.

5.Carefully wipe off the fan blades and motor with a soft cloth. Do not bend the fan blades. If the fan blades are excessively dirty, wash with warm, soapy water and rinse thoroughly.
