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. 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.

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, for details.

C. DRAINS

1. Sufx “D” units (e.g. MOD-300TD) have drains for each pan,

with each pan having an individual drain valve.

OPERATION

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.

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

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.

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.

Stir thick food items frequently
to keep food heated uniformly.

WET OR DRY OPERATION for WARMERS

1. Carefully read the description of the warmer operation on the

specication 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. 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.

Keep insets covered to
maintain food quality and
temperature.

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.

E-MOD 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.

Food temperature will vary from
the control set temperature
based on the moisture content
and consistency of the food
product.

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 specically 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 (specic 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 :
