Hoshizaki Ice Machine DCM-270BAH(-OS): Cleaning and Sanitizing Checklist

Cleaning Prep:

• 1. Close the water supply line shut-off valve and dispense all the ice from the storage bin.

• 2. Move the power switch to OFF. Remove the Louver & Air Filter. Move the control switch to DRAIN.

• 3. Move the power switch to ON. Allow the icemaker to drain completely. Move the power switch to OFF. ATTENTION! WAIT 1 MINUTE AFTER POWERING OFF, to allow control board to de-energize. Otherwise there will be a long delay before ICE or DRAIN will activate.

• 4. Unplug the icemaker from the electrical outlet. Dilute Hoshizaki Scale Away with warm water (see Table below). Remove the Front Panel*, Top Panel, Bin Top, Agitator, Drip Ring, Grille, and Spouts A & B**. Pour cleaning solution over the Extruding Head until the Evaporator Assembly and the Reservoir are full and the solution overflows into the Drain Pan. Allow to soak for 10 minutes. *Push-button models: Take care in disconnecting the button connector. **Use a 15mm socket with an extension to easily remove recessed thumb screws.

• 5. In bad water conditions, a more thorough soaking may be required. Follow Step 4, then place a clamp on the Reservoir hose that will block the flow to the evaporator assembly. Pour additional cleaning solution over the Extruding Head until the Evaporator Assembly is full. Allow to soak. Otherwise, continue to Step 6.

• 6. Using a nylon scouring pad, nylon brushes, and cleaning solution scrub the Storage Bin, Bin Top†, Agitator, Drip Ring, Grille, Spouts A & B, Ice Chute, and Drain Pan. † Be sure to keep the microswitch mounted on the Bin Top dry.

• 7. Remove the clamp (if installed in Step 5) from the Reservoir hose. Rinse all parts thoroughly with clean water before reassembling the Drip Ring, Agitator, Bin Top, and Front & Top Panels.

• 8. Move the control switch to ICE. Plug the icemaker into the electrical outlet. Move the power switch to ON. Make ice using the cleaning solution until it stops, dispose of ice. Move the power switch to OFF. ATTENTION! Icemaker might make noise/squealing when first started due to scale being removed from auger/evaporator. This is normal in bad water conditions and will subside after 20 min
