PREVENTIVE MAINTENANCE

4.1 ROUTINE CLEANING

To remove spilled or dried mix from the freezer exterior, simply wash in the direction of the finish with warm soapy water and wipe dry. Do not use highly abrasive materials as they will mar the finish.

4.2PREVENTATIVE MAINTENANCE

It is recommended that a maintenance schedule be followed to keep the freezer clean and operating prop- erly.

WARNING

NEVER ATTEMPT TO REPAIR OR PERFORM MAINTENANCE ON FREEZER UNTIL THE MAIN ELECTRICAL POWER HAS BEEN DISCON- NECTED.

A. Daily

1.The exterior should be kept clean at all times to preserve the lustre of the stainless steel. A mild alkaline cleaner is recommended. Use a soft cloth or sponge to apply the cleaner.

2.Remove the drip tray and insert. Clean the drip tray and insert and front of the freezer with a soap solution.

B. Weekly

1.Check “O” Rings and rear seal for excessive wear and replace if necessary.

2.Clean filter. To remove lift up and pull bottom out and down, then wash, dry and reinstall.

C. Monthly

CAUTION

THE FREEZER HAS AN AIR COOLED CONDENSER AND MUST HAVE PROPERAIR CIRCU- LATION. FAILURE TO CLEAN THE CONDENSER ON A REGULAR BASIS MAY RESULT IN SERIOUS FREEZER DAMAGE AND COULD VOID FREEZER WARRANTY.

1.Visually inspect the condenser for dirt by shining a light through the coil from the fan side of the con- denser.

2.If the condenser is dirty, using compressed air or CO2 tank, blow out the dirt from the fan side of the condenser.

3.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.

4.3 EXTENDED STORAGE

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

A.Turn CLEAN/OFF/SERVE switch to the OFF position.

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

C.Clean thoroughly with a warm 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 or sanitizing solution stand in the hopper or in the freezer barrel during the shutdown period.

D.Remove, disassemble, and clean the front door, and agitator parts. Place the agitator blades and the front agitator support bearing in a plastic bag with a moist paper towel to prevent them from becoming brittle.

4.4 CONSISTENCY ADJUSTMENT
