3.5 CLEANING DISASSEMBLED PARTS
Disassembled freezer parts require complete cleaning,
sanitizing and air drying before assembling. Local and

Some state health codes require a four sink process (pre-
wash, wash, rinse, sanitize, air dry), while others require
a three sink process (without the pre-wash step). The
following procedures are a general guideline only. Consult
your local and state health codes for procedures required
in your location.
