Figure 27. Condenser and Filter

Thecondenserandcondenserfilterrequireperiodiccleaning. To clean, refer to the following procedures.

WARNING

DISCONNECT FREEZER FROM ELECTRICAL SUPPLY SOURCE BEFORE SERVICING.

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.

3.Visually inspect the condenser for dirt by shining a light through the coil from the back (inside) of the condenser (Figure 28).

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

5.Using compressed air or a CO2 tank, blow out the dirt from the back (inside) of the condenser. Most of the dirt will cling to the wet towel.

NOTE

This procedure will result in a very loud noise.

6.An alternative method of cleaning the condenser is to use a condenser brush and vacuum.

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.

3.14 EXTENDED STORAGE

Refer to the following steps for storage of the freezer over any long period of shutdown time:

A.Turn the CLEAN-OFF-ON switch to the OFF posi- tion.

B.Disconnect (unplug) from the electrical supply source.

C.Clean thoroughly with a warm water detergent all parts that come in contact with the mix. Rinse in clear water and dry all parts. Do not sanitize.

NOTE

Do not let the cleaning solution stand in the hopper or in the freezer barrel during the shutdown period.

D.Remove, disassemble and clean the front door, mix inlet regulator and auger parts. Place the auger flights in a plastic bag with a moist paper towel to prevent them from becoming brittle.

E.On water cooled freezers, shut off and disconnect water supply at rear of freezer; run compressor for 2-3 minutes to open water valve, and blow out all water first through inlet then outlet line, using air or carbon dioxide.
