PLUGS
OPERATING INSTRUCTIONS
Plug Coldwell in and turn on the power switch. The unit has been calibrated at the factory for 35°
F-39° F at sea level. Wait about 45 to 60 minutes for the unit to cool. If the product is too cold or
too warm, adjust the thermostat. The thermostat adjustment is located above the power switch on
the compressor housing. To access the thermostat adjustment, remove the hole cover to reveal
the at screw driver adjust shaft. Turning the screw 1/4 turn clockwise will lower the temperature
approximately 6° F. Conversely, turning the screw 1/4 turn counterclockwise will raise the temperature
5° F. If you are unable to set your Coldwell to the desired temperature, contact your factory authorized
service agent for adjustment.
To avoid product in container from freezing, make sure the container is not touching the wall of the
cold well.
1. All food service equipment should be operated by trained personnel.
2. Never hold food below 150°F or above 40°F.
MAINTENANCE
Once a week or more often if necessary clean the unit thoroughly. Turn o the unit and allow it to cool.
Pan supports are to be removed for cleaning. Machine washing is preferred but hand washing is
acceptable. Follow all state and local codes for sanitation when cleaning the pan supports.
STAINLESS STEEL: To remove normal dirt or product residue from stainless steel, use ordinary soap
and water (with or without detergent) applied with a sponge or cloth. Dry thoroughly with a clean cloth.
Never use vinegar or corrosive cleaner. Do not use chorine based cleaners.
6
To remove grease and food splatter or condensed vapors that have baked on the equipment, apply
cleaners to a damp cloth or sponge and rub cleanser on the metal in the direction of the polished lines
on the metal. Rubbing cleanser as gently as possible in the direction of the polished lines will not mar
the nish of the stainless steel. NEVER RUB WITH A CIRCULAR MOTION. Soil and burnt deposits
which do not respond to the above procedure can usually be removed by rubbing the surface with
SCOTCH-BRITE scouring pads or STAINLESS scouring pads.
CAUTION: Do not use ordinary steel wool as any particles left on the surface will
rust.
NEVER USE a wire brush, steel or abrasive scouring pads (except stainless), scraper, le or other steel
tools. Surfaces which are marred collect dirt more rapidly and become more dicult to clean. Marring
also increases the possibility of corrosive attack.
NEVER use any corrosive cleaner. Use only cleaners approved for stainless steel.
NEVER use cleaning solvents with a hydrocarbon base.
WARNING: Never clean any electrical unit by immersing it in water. Turn o before
cleaning surface.
WARNING: SHOCK HAZARD - De-energize all power to equipment before cleaning
the equipment.
