Cleaning The Condenser

!Warning

Disconnect electric power to the ice machine at the electric service switch before 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. Follow the steps below.

!Warning

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

1.The washable aluminum filter on self-contained 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: Blow compressed air through the condenser fins from the inside. Be careful not to bend the fan blades.

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

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

6.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.

!Caution

If you are cleaning the condenser fan blades with water, cover the fan motor to prevent water damage.

Removal from Service/Winterization

Special precautions must be taken if the ice machine is to be removed from service for an extended period of time or exposed to ambient temperatures of 0°C (32°F) or below.

!Caution

If water is allowed to remain in the ice machine in freezing temperatures, severe damage to some components could result. Damage of this nature is not covered by the warranty.

1.Disconnect the electric power at the circuit breaker or the electric service switch.

2.Turn off the water supply.

3.Remove the water from the water trough.

4.Disconnect the drain and the incoming ice-making water line at the rear of the ice machine.

5.Make sure no water is trapped inside the ice machine incoming water lines, drain lines, distribution tubes, etc. Blow compressed air through the line if necessary.
