units..
b. Warmers may be used wet, or may be used dry. However warmers may NOT be
used wet-to-dry or dry-to-wet unless they have been allowed to cool to room
temperature between the change in wet or dry operation.
c. Wells Manufacturing recommends operating WET for consistent food heating.
d. If your wet-operation warmer is allowed to run dry, turn it OFF and allow
to cool to room temperature before adding water.
3. If the warmer is to be used for WET operation, add approximately 1″ of hot
tap water before turning the warmer on. Use of hot water will allow a faster
preheat.
a. Check the water level frequently and add hot water as necessary to prevent
the warmer from running dry. Do not add water to the warmer if it has run dry.
b. If your wet-operation warmer is allowed to run dry, turn it OFF and allow
to cool to room temperature before adding water.
4. Damage caused by allowing a wet-operation warmer to run dry, is NOT
covered by warranty. Damage caused by adding water to a dry warmer when hot is
NOT covered by warranty.
PRE-HEATING THE WARMER
1. Place desired pan(s) or inset(s) with appropriate adapter top on warmer.
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 30 minutes, then set the control
for the desired temperature. Be sure to keep the warmer covered during preheat
and operation.

AUTOFILL WARMERS 1. Autofill warmers sense water level by a sensor placed at
the proper
level. For manifolded autofill warmers, the water level sensor / fill tube is
in one pan only.
2. Water fills the pan through an inlet tube. All other sections if
manifolded, fill at the same time through the drain manifold.
3. The autofill function is active only when the thermostat for the pan with
the water level sensor is turned ON .
4. Make sure the drain valve is fully closed before turning any t-stats ON.
5. DO NOT use autofill warmers in the dry mode. This may damage the
water level sensor probe. NEVER turn the thermostat ON for the pan with the
probe and fill tube unless the entire warmer unit is to be used in the wet
mode.
6. Clean water level sensor daily to maintain water level in warmer.
OPERATION 1. Always use an inset. DO NOT place food directly into the
warmer.
2. Check water level in wet-operation warmer frequently during use. Running
warmers dry will lower the temperature of the food in the insert pan, and may
damage the warmer.
3. Alternating between wet and dry operation in any individual warmer is NOT
recommended.
4. DO NOT use metal tools, steel wool, or caustic or abrasive cleanser to
clean warmer pan.
WARMERS WITH MANIFOLDED DRAIN 1. Water poured into any one section will seek
the same water level with
all sections on the manifold.
2. Make sure the drain valve is fully closed before filling warmer. 3. All
units that are manifolded with the AUTOFILL unit, MUST be on
the same elevation and completely level with each other to operate correctly.
Stir thick food items frequently to keep food heated uniformly.
Keep insets covered to maintain food quality and temperature.

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, table
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.
