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 environ- ment 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. PM kit #W0890157 con- tains the standard replacement parts needed for preventative maintenance including o-rings, standard seal kit stator bearings and drive belt. Units with a coconut oil product seal should order all parts separately. Units with scraper blade dasher will require the scraper blades be ordered separately.

•Verify ventilation is adequate (Air-cooled units: 6” minimum on both sides, open at top, and as far as possible from

dust sources; Water-cooled units: 0” on both sides, 3 -6” at rear of unit and open at top).

•Verify adequate water flow and drain connections on water-cooled versions.

•Check product temperature and consistency for proper setting (refer to product manufacturer’s recommendation) - adjust if necessary. Where equipped be sure to check the temperature in both the hopper and cylinder.

•Ensure product is being mixed properly and is within specification (check brix - most products should be around 13% - refer to product manufacturer’s recommendations for exact recommended brix).

•Check for any leaks.

•Empty product from the unit. Disassemble unit completely (as if for cleaning).

•Clean and sanitize all disassembled parts following the cleaning instructions in the manual.

•Clean and sanitize hopper, freezing cylinder and splash zones on the machine.

•Check condition of all panels and lids - replace if necessary.

•Check dasher scraper blades for wear if equipped - replace once per year minimum.

•Check dasher for signs of wear - replace if necessary. Verify alignment when replacing.

•Check valve body gasket for wear - replace once per year minimum.

•Check valve body knobs (used to hold valve body in place) - replace if necessary.

•Check condition of shaft seals and stator bearings - replace once per year minimum.

•Inspect drip cup at back end of freezing cylinder for signs of seal leakage.

•Replace o-rings on hopper float (where necessary), dispense valves and carb tubes (lubricate).

•Lubricate parts where appropriate (dispense valve o-rings, carb tube o-rings, rubber boot of stationary shaft seal).

•Re-assemble unit and sanitize hopper and freezing cylinder by running CLEAN cycle.

•Clean and sanitize spinner if equipped.

•Check operation of merchandiser and mode lights - replace light bulbs if necessary.

•Clean reusable filter if equipped. Check condition of filter and replace if necessary.

•Clean condenser.

•Inspect the drive shaft and motor shaft bearings for excessive wear (drive shaft hole rounding out) - replace if necessary. Verify alignment when replacing.

•Check V-belt tension (should be 1/2” - 5/8”) and verify all set screws are tightened - adjust if out of range. Replace belt once per year minimum.

•Verify compressor operation and freezer controller operation.

•Check electrical connections (outlet should be properly grounded with amperage capacity equal to or over the amperage specified on the serial tag).

•Check fan operation (condenser fan) and clean fan blades if necessary.

•Review proper periodic care and cleaning instructions (disassembly, cleaning, sanitizing, lubrication, and re-assembly) with store personnel. Train store personnel to follow proper procedures (stress importance of store level maintenance ie. lubrication, filter cleaning, etc.).

•Make sure store personnel have appropriate supplies (lubricant, cleaning brushes and sanitizer) to care for machine.
