Cleaning after Disassembly
Inspect auger and check for damage to the following areas:
Top bearing seat
Top shaft seal area
Bottom bearing seat
Bottom seal area
Remove contamination from auger:
Clean the following with 460 grit emery cloths:
Auger
shaft
Auger flights (both sides - top and bottom)
Do not clean the cutting head with sandpaper (flakers only):
The cutting head self-cleans due to ice shear - emery cloth will dull the cutting edge.
Sand the auger with emery cloth until all scale is removed.
Evaporator barrel cleaning:
Assemble wheel stack on mandrel.
Drill and shaft extension are required:
Use speeds less than 200 rpm, slower = better.
Keep moving up and down; do not stop in one spot.
Scotch-Brite disc for cleaning:
Disc must be larger than inside diameter of barrel for even contact:
2" disc used on models QF0400, QC0700, and QF0800
4" disc used on models QF2300
Clean thoroughly with multiple passes of disc and clean cloths.
Thoroughly clean water inlet and ice outlet to complete the cleaning of the barrel.
