MAINTENANCE INSTRUCTIONS
Never use metal implements, wire brushes, abrasive scratch pads or steel
wool to clean stainless steel.
Warmer pans, insets and other vessels are subject to a harsher environment. Wells
Manufacturing uses an very high quality stainless steel (#304DDQ) for our food warmer
pans. Even the highest quality stainless steel, however, is mostly iron, and will rust, pit
and corrode under the following conditions:
• Poor Water Quality: Hard water (water with a high content of dissolved minerals)
will leave mineral deposits when allowed to dry. Calcium (lime) can buildup on
heated surfaces, even under water. If left unattended, hard water spots and lime
buildup can lead to rusting, corrosion and pitting.
M021B 2M-308086 Owners Manual for Autofill Built-In Bain Marie Warmers
Keep your stainless steel warmers clean and free from calcium buildup.
Use alkaline, alkaline chlorinated or non-chloride cleanser.
Use citric acid-based cleaners to remove calcium deposits.
For additional information, please read the NAFEM Stainless Steel Equipment and
Cleaning Guide. Contact NAFEM at :

CLEANING INSTRUCTIONS
CAUTION: 1. Wipe entire unit down using a clean cloth or sponge and mild
BURN HAZARD detergent. Carefully wipe any debris and residue from the water
level sensor.
Allow warmer to cool
completely before cleaning. 2. Use a plastic scouring pad to remove any hardened food particles
or mineral deposits. IMPORTANT: DO NOT use steel wool for
cleaning.
4. Inspect warmer tank for damage. Damage to the tank may allow
grease and water to leak into insulation and heating element,
causing a potential fire and/or electric shock hazard. Contact your
Authorized Wells Service Agency to inspect warmer if water or
grease contamination is suspected.
M021B 2M-308086 Owners Manual for Autofill Built-In Bain Marie Warmers
5. Add proper amount of warm water. Turn control knob ON and
