Maintenance; Preparing The Icemaker For Long Storage - Hoshizaki KM-590DJE-R452 Instruction Manual

B. Maintenance
The maintenance schedule below is a guideline. More
frequent maintenance may be required depending on water
quality, the icemaker's environment, and local sanitation
regulations.
WARNING
1. Except as specified below, only qualified service
technicians should attempt to service this icemaker.
2. Move the power switch to the "OFF" position and
disconnect power before servicing.
1. Stainless Steel Exterior - Performed by Qualified
Service Technician or Owner/Manager
To prevent corrosion, wipe the exterior occasionally with
a clean, soft cloth. Use a damp cloth containing a neutral
cleaner to wipe off oil or dirt buildup.
2. Storage Bin and Scoop - Performed by Qualified Service
Technician or Owner/Manager
Clean the scoop and the storage bin liner using a neutral
cleaner. Rinse thoroughly after cleaning.
3. Air Filters - Performed by Qualified Service Technician
or Owner/Manager
Plastic mesh air filters remove dirt and dust from the air and
keep the condenser from getting clogged. As the filters get
clogged, the icemaker's performance will be reduced. Check
the filters at least twice a month. When clogged, use warm
water and a neutral cleaner to wash the filters.
4. Condenser - Performed by Qualified Service Technician
The condenser should be checked and cleaned once a year.
Instructions for the service technician can be found in the
Installation Manual supplied with this icemaker.

5) Attach a compressed air or carbon dioxide supply to the
icemaker water supply line drain valve.
6) Move the control switch to the "ICE" position.
7) Replace the front panel in its correct position, then turn on
the power supply.
8) Blow the icemaker water supply line out using the
