does not contain chlorine.
2. Rinse with clean water.
3. Dry with a soft cloth.
4. Polish with a soft cloth, wiping with the grain.
5. Wipe weekly with stainless steel cleaner.
Weekly Interior Cleaning

a safe temperature.
2. Disconnect power to the unit (unplug it or switch the
breaker off).
3. Remove all loose food particles from the inside walls,
floor, door liner and ceiling.
4. Scrub all interior surfaces and door gaskets with a
warm (100
o
F to 110
o
F) detergent solution and a soft
scrub brush.
5. Rinse with clean water and allow to air dry.
6. Restore power.
7. Return food to the unit when it has reached a safe
temperature.
Defrosting
ST units must be manually defrosted periodically. “Cold
Wall” units like the SM and ST maintain the air temperature
of the cabinet at the set point by cooling the walls below
the set point to approximately 20°F. Because the walls of
the cooler are below the freezing temperature of water,
ice may build up over time. It is important to occasionally
manually defrost the unit to minimize ice build-up.
To manually defrost your milk cooler:
1. Remove the product from your milk cooler and place it
in another refrigerated storage area.
2. Open the lids and doors of your milk cooler and unplug
the power to the unit.
3. Wait approximately 30 min for the frost to melt and
drain to the floor drain. Times may vary with ambient
temperature in the room and ice build-up.
WARNING: DO NOT SCRAPE THE WALLS TO SPEED UP
DEFROSTING. SCRAPING MAY RUIN SURFACE FINISH OR
PUNCTURE WALL AND DAMAGE REFRIGERATION TUBING
BEHIND THE WALL
4. After manual defrost, Close the lid and doors and power
the unit by plugging it into the outlet. Return product to
the cooler after the air in the cabinet has cooled to the
desired temperature.
