Disassembly and Cleaning Note: For cleaning and sanitizing before initial start-up remove carb tubes, dispense plungers, handles and springs from parts bag first. 1.
Disassembly and Cleaning (cont.) 8. Remove drip tray and empty contents. 9. Take all components to the cleaning area. 10. Prepare 1 gallon solution of hot tap water and a good grade of dishwashing detergent. 11. Thoroughly wash all components in a warm, mild detergent solution including the inside of the freezing cylinder and the mix storage hopper. DO NOT WASH COMPONENTS IN A DISHWASHER. 12.
Sanitizing and Refilling 1. Reassemble carburetors by installing the two o-rings at the bottom of the carb tubes. 2. Place the carburetor assemblies in the bottom of each hopper. 3. Install the o-rings on each valve plunger and lay plunger assembly on a clean piece of paper towel. 4.

Clean-In-Place Procedure (Daily Cleaning) This equipment has been approved for a Clean-In-Place procedure that does not require complete disassembly on a daily basis. The unit still requires regular complete disassembly for cleaning and sanitizing. To perform the C-I-P procedure follow the instruction below: 1. Empty any product in the machine and turn to OFF. 2. Disassemble the dispensing valve assembly following the instructions in Disassembly and Cleaning. NOTE: Leave the valve block in place.
Preventative Maintenance Procedure (Every 6 to 12 Months) A preventative maintenance visit should be performed every 6 to 12 months depending on the usage and environment where the unit is placed. (Ex. seasonal machines - once before season, year round machines - twice per year). The following procedures should be performed during a preventative maintenance visit. This does not take the place of daily care and cleaning procedures as described by local health codes and the manual.
How to Clean Condenser (Air-Cooled Unit Only) NOTE: Loss of refrigeration efficiency will result if condenser is allowed to become dirty. Excessive compressor run time or loss of capacity are a good indication that the condenser needs to be cleaned. 1. Disconnect electrical power. 2. Remove side panels. 3. Place a damp towel over the side of the condenser opposite the fan motor. 4. Use compressed air or CO2 blow out dirt from the fan side of the condenser.
GENERAL TROUBLESHOOTING Freezer problems typically originate from three sources - improper operation, mix problems or mechanical malfunction. Always check for improper operation and mix problems first, as they are the most common cause of most equipment problems. CAUTION Always disconnect power before attempting any maintenance procedures. Only a qualified service technician should perform electrical and mechanical adjustments or repairs.
