3.5 CLEANING DISASSEMBLED PARTS
Disassembled freezer parts require complete cleaning,
sanitizing and air drying before assembling. Local and
state health codes will dictate the procedure required.
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.
A. To clean the freezer parts, disassemble all parts.
(Refer to section 3.4 for the disassembly of freezer
parts.)
B. Place all front door and auger parts in clean 90° to
110°F (32°C to 43°C) water and wash thoroughly
(four sink procedure only).
C. Place all parts in 90° to 110°F (32°C to 43°C) , mild
detergent water and wash thoroughly.
D. Rinse all parts with clean 90° to 110°F (32°C to
43°C) water.
F. Sanitize all freezer parts following procedures out
lined below.
