Scotsman AFE424 User manual

Preventive Maintenance:
Ice Machines require periodic maintenance to be able to deliver like-new
reliable performance.
The maintenance will be in three areas:
·The ice machine’s water system
·The ice storage bin.
·Air cooled models need their condenser cleaned.
Schedule:
Note: In some areas the water supply to the ice maker will have a great
deal of minerals in it, and that will result in an evaporator and auger
becoming coated with these minerals, requiring more frequent
maintenance than twice per year.
Ice Machine Water System, including water filters:
·Clean water system and change filters a minimum of every 6 months.
Auger and Top Bearing Inspection:
·Every 12 months.
Remote or Air Cooled Condenser Coil Cleaning:
·Every 6 months.
Bin Liner Cleaning and Sanitizing:
·Every Month.
For the Owner or Operator:
Several items can be “do it yourself” procedures:
·Water filter change - estimated time 5 minutes
·Air filter cleaning or change - estimated time 10 minutes
·Storage bin cleaning & sanitizing - estimated time 25 minutes
·De-scaling of the ice machine water system - estimated time 60 minutes
The following items will require a technician:
·Condenser coil cleaning
·Top bearing inspection
