Disassembly, Defrost & Cleaning

IMPORTANT! These cleaning instructions are intended as a guide. Refer to your local, state, and federal regulations for any additional instructions and for cleaning frequency requirements.

Remove all Baskets from the dispense area. Open the Cabinet Door and remove the left and right Hopper Assemblies by lifting the front of the Hopper up slightly and pulling forward on assembly.

Remove any unused product from the Hoppers and Accumulator Housings by emptying the product into an approved storage container. Place the storage container immediately into a freezer to maintain frozen product.

Defrost

Because the dispenser employs a cold wall design, it will be necessary to manually defrost the cabinet daily. After removing the product, using the On/Off Switch turn the power OFF and unplug the dispenser power cord. Open the Cabinet Door and allow 1 hour to defrost.

Note: Failure to turn the dispenser power off prior to defrosting the cabinet may result in a cabinet over-temperature error. (Error -5-).

Caution: Never use a sharp object to remove frost build-up. Never drill or otherwise puncture cabinet walls or top.

Lift and remove the Accumulator Housings.

For dispensers with removable accumulator doors: remove the Accumulator Doors by rotating the chucks Counter-Clockwise until unlocked, then pull the accumulator doors forward.

Take the removable components from the Dispenser to the washing area. Wash them with a hot solution of detergent and water. Rinse each component with clear water and sanitize (wash/rinse/sanitize) (HCS). Allow components to air dry,.

NOTE: The removable components are NOT dishwasher safe.

Move the Dispenser out from the wall to clean behind and underneath it.

Do NOT roll the dispenser to the back sink for cleaning, this will cause unnecessary wear on the dispenser.

Once the cabinet is free of frost, wipe down the internal and external cabinet with a hot solution of detergent and water. Rinse with clear water and repeat wipe down with sanitizing solution (HCS) and allow to air dry.

Warning: Do not spray the Dispenser with Liquid or Solvents. The Dispenser does not provide a water tight seal. Contaminants and moisture may get into sensitive components.

Dry all components and reassemble the Dispenser (page 6-11). Move Dispenser back into place.

Notice: The dispenser must be accessible from all sides for routine cleaning and maintenance. A minimum of 0.5” (13 mm) clearance on both sides and 2” (50 mm) behind the dispenser is recommended.

Lift and remove left and right Flap door assemblies.

Remove left and right Basket Guide assemblies from the Dispenser by lifting up on the front of the guide until it unlatches, then pull outward and upward. Remove Drip Tray by lifting, tilting and sliding forward.
