FEATURES & OPERATING CONTROLS
2
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. 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.
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.
B. MOUNTING
1. Modular built-in warmers are be equipped with WELLSLOKS,
uniquely designed turnout tabs which help secure the warmer
top flange to the countertop.
2. See the Installation Instructions, supplied with the particular
appliance, for details.
C. DRAINS
1. “D” units (e.g. MOD-100D) have drains for each pan, with
each pan having an individual drain valve.
IMPORTANT:
DO NOT LEAVE ON
“PREHEAT”
Unit may cycle on hi-limit
control, leading to premature
failure of the hi-limit control
device.

OPERATION
6
WET OR DRY OPERATION for WARMERS
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.
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. Infinite Switch Controlled Warmers: Turn temperature control to
PREHEAT.
3. Allow warmer to PREHEAT for approximately 15 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 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.
CAUTION:
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.

MAINTENANCE INSTRUCTIONS

M012C.01 2M-308029 Owners Manual for Single-Well Inf.Sw. MOD-Warmers
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 heat-
ed 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 :
