WARNING

High voltage will shock, burn or cause death. Turn off and lock out main power disconnect before servicing. Do not operate machine with cabinet panels removed.

The air-cooled condenser is a copper tube and aluminum fin type. Condensing is totally dependent upon airflow. A plugged condenser filter, condenser, or restrictions in the louvered panel will restrict airflow. This will lower the capacity of the system and damage the compressor.

The condenser must be kept clean of dirt and grease. The freezer must have a minimum of 3” (7.5 cm) of ventilation on the right and left sides of the unit for free flow of air (Figure 29). Make sure the freezer is not pulling over 100° F (37° C) air from other equipment in the area.

The water-cooled condenser is a tube and shell type. The condenser needs a cool, clean supply of water to properly cool the freezer, inlet and discharge lines must be 3/8” I.D. minimum.

The condenser and condenser filter require periodic cleaning. To clean, refer to the following procedures.

1.Remove the Phillips head screw from the bottom of the right side panel, and then slide the panels down and out.

2.To remove the condenser filter, grasp the top and pull off. Visually inspect for dirt. If the filter is dirty, shake or brush excess dirt off the filter and wash in warm, soapy water. Once the filter is clean rinse thoroughly in warm, clear water and shake dry, taking care not to damage the filter in any way (Figure 28).

3.Visually inspect the condenser for dirt by shining a light through the coil from the back (inside) of the condenser.

4.If the condenser is dirty, place a wet towel over the front (outside) of the condenser.

Figure 28. Condenser and Filter

5.Using a vacuum, carefully clean the condenser coil from the inside and outside of the freezer. A stiff bristled brush may help in releasing debris from between the condenser coils (Figure 29).

NOTE

If the condenser is not kept clean, loss of refrigeration efficiency will result; causing extended run time or soft product consistency.

Water-cooled condensers need an unrestricted supply of cold, clean water.
