FEATURES & OPERATING CONTROLS
A. INFINITE SWITCH
IMPORTANT:
DO NOT LEAVE ON
“PREHEAT”
Unit may cycle on hi-limit
control, leading to premature
failure of the hi-limit control
device.
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
2
M012C.05 2M-308033 Owners Manual for Five-Well Inf.Sw. MOD-Warmers
1. “D” units (e.g. MOD-500D) have drains for each pan, with
each pan having an individual drain valve.
2. “DM” units (e.g. MOD-500DM) have the individual drain lines
manifolded together, with a single drain valve for the entire
manifold.

WET OR DRY OPERATION for WARMERS
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.
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:
M012C.05 2M-308033 Owners Manual for Five-Well Inf.Sw. MOD-Warmers
•
•
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.
