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.
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
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. Innite
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 innite 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 innite switch controls temperature by varying the ratio of “on”
time to “o󰀨” time. Thus, no temperature sensing devise is required.
B. MOUNTING
1. Built-in warmers are equipped with E-Z Lock, 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 with a “D” have drains for each pan, with each pan having an
individual drain valve.
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.

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 o󰀨 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. APW
Wyott 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.

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 o󰀨 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. APW
Wyott 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 :
