FEATURES & OPERATING CONTROLS
A. THERMOSTAT
1. On thermostatically controlled warmers, power is applied to the
heating element according to the control knob position and the actual
temperature at the temperature sensing thermobulb.

CONTROL
KNOB
IL2468
IMPORTANT:
DO NOT LEAVE ON
“PREHEAT”
Unit may cycle on hi-limit
control, leading to premature
failure of the hi-limit controls
device.
2. The desired temperature is controlled by rotating the temperature
control knob. The knob has a numeric scale, where higher numbers
correspond to higher temperature.
3. On warmers equipped with an indicator light, the light will glow when
the thermostat is calling for heat (i.e. the element is energized).
4. The TEMPERATURE CONTROL KNOB will rotate approximately 300º,
and will reach a “stop” at both ends.
The OFF position is marked.
NOTE: The dial position is an indication of the temperature setting. Actual
temperature will vary depending upon the type of product and food
consistency.
A. INFINITE SWITCH
2. The desired temperature is controlled by rotating the TEMPERATURE
CONTROL KNOB. The knob may have a numeric scale, where
higher numbers correspond to higher temperature. LO is the lowest
temperature setting; PREHEAT is a “continuous on” setting. Infinite
switch controlled warmers are equipped with a hi-limit device to prevent
overheating. The hi-limit will self-reset after the warmer has cooled.
WELLSLOKS
IL2469
3. On warmers equipped with an INDICATOR LIGHT, the light will glow
when the infinite switch is in any position other than OFF.
4. The TEMPERATURE CONTROL KNOB will rotate without stopping,
with PREHEAT and OFF having obvious detents.The OFF position is a
“positive” OFF (i.e. the switch is positively held in the open position).
NOTE: An infinite switch controls temperature by varying the ratio of “on”
time to “off” time. Thus, no temperature sensing devise is required.

IMPORTANT: Electrical
installation other than as
specified on the specification
sheet will void the UL listing,
and may void the warranty.
NOTE: Plumb connections
must be made in compliance
with all Federal, State and
Local Plumbing Codes and
Ordinances.
OPERATION
WET OR DRY OPERATION for WARMERS
HOT SURFACE
Exposed surfaces can be hot
to the touch and may cause
burns.
CAUTION:
SHOCK HAZARD
DO NOT splash or pour water
onto control panel or wiring.
Always use an inset.
DO NOT place food directly
into the warmer.
1. Carefully read the description of the warmer operation on the specification sheet.
2. a. Most warmers are designed for WET OR DRY operation.
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.
Always pour hot water into the
warmer before it is preheated.
DO NOT pour water into a
dry, heated warmer. This may
damage the unit.
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.
DO NOT put ice into a
warmer pan. This will cause
condensation on the inside of
the warmer. Damage caused
by condensation is NOT
covered by warranty.
PRE-HEATING THE WARMER
Stir thick food items frequently
to keep food heated uniformly.
Keep insets covered to
maintain food quality and
temperature.
DO NOT use AUTOFILL
warmers in the dry mode.
This may damage the water
level sensor. NEVER turn the
thermostat ON for the pan
with the sensor and fill tube
unless the entire warmer unit
is to be used in the wet mode.
WATER LEVEL
SENSOR
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, normally in the far left pan.
2. Water fills the pan through an inlet tube. For manifolded autofill
warmers, the fill tube is normally in the far left pan. All other sections 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.

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.
5. The autofill function is only activated when the far left thermostat is
turned ON. For manifolded autofill warmers, be sure to turn far left
thermostats ON before turning any other control ON, to avoid heating a
dry pan.

CAUTION:
OPERATION (continued)
AUTOFILL WARMERS continued
6. 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.
7. 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. Manifolded warmers have a single drain valve.
2. Water poured into any one section will seek the same water level with all
sections on the manifold.
M011C.02 2M-Z16298 Owners Manual for Built-In Well Modular Warmers
3. Make sure the drain valve is fully closed before filling warmer.
Digital Control Operation
This control will provide close regulation of the temperature in the basin and
give an indication of the air temperature surrounding the food container. The
temperature is adjustable from 100° to 200°F. Pressing the ON/OFF button of
the temperature control activates the heating circuit. The setpoint is displayed
by pressing and holding the TEMP button. Adjust the regulated temperature
by pressing the + or – buttons while holding the TEMP button down. The
actual basin temperature is displayed when no buttons are pressed and the
control is in the ON mode. The dot in the lower corner of the display indicates
when the control is calling for heat.
When provided the master power switch controls the heating circuit and the
automatic water fill ocntrol. Turn “OFF” the power switch when draining or
cleaning the unit.

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.
M011C.02 2M-Z16298 Owners Manual for Built-In Well Modular Warmers
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.

Cleaning Guide. Contact NAFEM at :
