WATER LEVEL
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.
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.
IMPORTANT:
DO NOT LEAVE ON
“PREHEAT”
Unit may cycle on hi-limit
control, leading to premature
failure of the hi-limit controls
device.
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
1. On INFINITE SWITCH CONTROLLED warmers, power is applied to
the heating element based on the control knob position, which varies
the duty cycle of the heating element.
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. Innite
switch controlled warmers are equipped with a hi-limit device to prevent
overheating. The hi-limit will self-reset after the warmer has cooled.
3.
On warmers equipped with an INDICATOR LIGHT, the light will glow
when the innite 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 innite switch controls temperature by varying the ratio of “on”
time to “off” time. Thus, no temperature sensing devise is required.
B. MOUNTING
1. MOD-series built-in warmers may are equipped with wellsloks, uniquely
designed turnout tabs which help secure the warmer top ange to the
countertop.
2. See the Installation Instructions, supplied with the particular appliance.
C. DRAINS
1. Models wih a “D” (e.g. M200TD) have drains for each pan, with each
pan having an individual drain valve.
2. Models with a “DM” units (e.g. M200TDM) have the individual drain lines
manifolded together, with a single drain valve for the entire manifold.
D. AUTOFILL
1. On AUTOFILL units, water level is automatically fed into the
“master” pan whenever that pan’s thermostat is ON .
2.
Water level is sensed by a WATER LEVEL PROBE in the “master” pan.

unless the entire warmer unit
is to be used in the wet mode.
WET OR DRY OPERATION for WARMERS
1. Carefully read the description of the warmer operation on the
specication 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.
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
to a dry warmer when hot is NOT covered by warranty.
. Damage caused by adding water
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. Autoll warmers sense water level by a sensor placed at the proper
level. For manifolded autoll warmers, the water level sensor / ll tube
is in one pan only, normally in the far left pan.
2. Water lls the pan through an inlet tube. For manifolded autoll
warmers, the ll tube is normally in the far left pan. All other sections ll
at the same time through the drain manifold.
3.
The autoll 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. The autoll function is only activated when the far left thermostat is
turned ON. For manifolded autoll warmers, be sure to turn far left
thermostats ON before turning any other control ON, to avoid heating a
dry pan.

6. DO NOT use autoll 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 ll 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.
3.
Make sure the drain valve is fully closed before lling 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 ll 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 nished with a grain
pattern. This pleasing nish 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 specically 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 (specic 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.
For additional information, please read the NAFEM Stainless Steel Equipment and
Cleaning Guide. Contact NAFEM at :
