a. Check the water level frequently and add hot water as
necessary to prevent the warmer from running dry.
b. Do not add water to the warmer if it has run dry.
c. If your warmer is allowed to run dry, turn it OFF and allow
to cool to room temperature before adding water.

3. Damage caused by allowing a this warmer to run dry, is NOT

a. Insets are available as accessories in 2½ qt., 4qt., 7 qt.,
and 11 qt. sizes with lids and adapter tops.
b. For dry operation, a 6” deep pan or inset is recommended.

2. Turn temperature control to HI or highest temperature setting.

3. Allow warmer to preheat for approximately 10 minutes, then set
the control for the desired temperature. Be sure to keep the
warmer covered during preheat and operation.

OPERATION

1. Always use an inset. DO NOT place food directly into the
warmer.

2. Check water level in warmer frequently during use. Running
warmers dry will lower the temperature of the food in the insert
pan, and may damage the warmer. DO NOT allow dry
operation of warmer.

3. DO NOT use metal tools, steel wool, or caustic or abrasive
cleanser to clean warmer pan.

CAUTION:

Hot Surface

Exposed surfaces can be hot

MAINTENANCE INSTRUCTIONS

CARE OF STAINLESS STEEL

Stainless steel is a marvelous material: strong, lustrous and low maintenance. With a minimum
of care, it will normally retain its beauty and durability for the life of the equipment. In some
applications, however, special care is required in order to maintain stainless steel’s special prop­erties.

External components, such as cabinets and control panels, are finished with a grain pattern.
This pleasing finish is best maintained by cleaning with a non-abrasive cleanser applied with
a soft cloth. Rub only in the direction of the grain. In the absence of visible grain, rub only along
the longest axis of the appliance.

Restore stainless steel’s luster by applying a polish specifically made for stainless steel. Spray
on, wipe off with a soft cloth, rubbing in the direction of the grain.

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.

• Contact with Chlorides: Chlorides (specific compounds of chlorine) are found in food, ta-

ble salt and many cleansers. Chlorides can attack the surface of stainless steel, resulting in
corrosion and pitting.

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.

Guide. Contact NAFEM at :
