Brush Cleaning
Step 1
Prepare a sink with an approved 100 PPM cleaning/
sanitizing solution (examples: Kay-5® or Stera-
Sheen®). USE WARM WATER AND FOLLOW THE
MANUFACTURER'S SPECIFICATIONS. Make sure
all brushes provided with the freezer are available
for brush cleaning.
Step 2
Thoroughly brush clean all disassembled parts in the
cleaning solution, making sure all lubricant and mix
film is removed. Be sure to brush all surfaces and
holes, especially the holes in the pump components
and the draw valve holes in the freezer door.
Rinse all parts with clean, warm water. Place the
parts on a clean, dry surface to air dry overnight.
