Scotsman HID Service manual
HID Ice Maker-Dispenser PM
Planned Maintenance:
Ice Machines require periodic maintenance to be able to deliver like-new reliable performance. That
maintenance will be in ve areas:
• Drip tray and drain system
• Air cooled condenser lter and condenser
• Ice dispense bin and rotor
• Photo eye ice level control
• Ice making water system
The maintenance includes:
• Scale removal
• Sanitization
• Filter cleaning or change
Schedule:
Typically twice per year for scale removal and sanitizing. At some sites the water supply to the ice machine
will contain signicant quantities of minerals, and that will result in a water system becoming coated with these
minerals, requiring more frequent maintenance than twice per year.
Drip Tray and Drain:
• Weekly ush out recommended
Air Filter Cleaning:
• Monthly and every 6 months with the ice machine scale removal
Ice Dispense Bin and Rotor Cleaning and Sanitizing:
• At the same time of scale removal and ice machine sanitization, more frequently if needed
Photo Eye Ice Level Control
• At the same time of scale removal
Ice Machine Water System, including water lters:
• Remove scale from water system and change lters a minimum of every 6 months
• Sanitize the water system whenever the scale has been removed
For the Owner or Operator - several items can be “do it yourself” procedures:
• Water lter change - estimated time 5 minutes
• Air lter cleaning or change - estimated time 10 minutes
Ice Dispense Bin and Rotor Cleaning and Sanitizing
Necessary Materials
Hand tools, cleaning supplies including scale remover and sanitizer, plus hand protection are recommended.
Frequency and Background:
Recommended minimum time between cleanings is 6 months. To aid in determining if the machine has not
been cleaned in 6 months, a Time To Clean light will glow after 6 months of power up time. Cleaning the
machine with the following process will reset that light and the timer that controls it. More frequent cleanings
may be required based on the mineral content of the water, run time and potential airborne contamination.
