NOTE: Use care when cleaning around thermowell sensing tube; the small capillary is easily broken. Rinse all parts in clean water.

7.In a 5 gallon bucket, mix a sanitizing solution of 1/2 oz. of sanitizer to 1 gallon of warm water (100° to 120° F).

8.Place all small, loose parts into the sanitizing solution and allow them to soak for 10 minutes.

9.Using a clean cloth and the sanitizing solution, wipe down the interior of the ice chute, thermowell door tracks, ice bin top, and around bin opening. Allow to air dry.

10.Reassemble the float chamber cover, ice chute gasket and cover, and bin door.

11.Turn unit switch on and allow machine to make ice for at least 1/2 hour then discard all of the ice.

DO NOT ALLOW ICE WITH SANITIZER IN IT TO BE USED.

NOTE: APPROVED SANITIZER: Household bleach such as Hi-Lex or Clorox.

WATER TREATMENT

During the freezing process, the impurities in the water have a tendency to be rejected.

However, the more dissolved solids in the water, the more troublesome the freezing operation will be. Bicarbonates in the water are the most troublesome of the impurities. These impurities will cause scaling on the evaporator, clogging of the float valve mechanism and other parts in the water system. If the concentration of impurities is high, wet mushy ice may be the result.

Parts of the ice maker, that are in contact with the water or ice, may corrode if the water is high in acidity. In some areas, water may have to be treated in order to overcome some of the problems that arise because of the mineral content.

IMI Cornelius has water filter/treatment systems available to control impurities found in your water supply. Contact your local dealer for more information.

WINTER STORAGE

If the unit is to be stored in an area where the temperature will drop below freezing, it is most important that all water lines be drained to prevent them from freezing and possible rupture.

To blow out the water line, disconnect the water supply at the cabinet inlet and use air pressure to force the water into the water reservoir pan. This can then be removed from the water pan.

WATER COOLED CONDENSER - To remove water from condenser unhook water supply and attach compressed air hose. Start machine. As head pressure reaches the appropriate level opening the water regulating valve, the compressed air will force the water out. Do not let the machine operate longer than necessary.

CLEANING THE CONDENSER (AIR COOLED)

In order to produce at full capacity, the refrigeration condenser must be kept clean. The frequency of cleaning will be determined by surrounding condition. A good maintenance plan calls for an inspection at least every two months.

Remove the unit compartment grill at the front. With a vacuum cleaner, remove all accumulated dust and lint that has adhered to the finned condenser.

CAUTION: Condenser cooling fins are sharp. Use care when cleaning.
