TEMPERATURE
CONTROL
(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.
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
IL2614
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. Top-mounted drop-in warmers 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. “D” units (e.g. SS-10D) have drains for each well, with each pan
having an individual drain valve.

INSTALLATION
4. For “top-mounted” warmers (i.e. warmers mounted from above
the counter top):
a. Verify that provided sealants are applied to the underside
of the warmer top ange prior to setting the unit into the
cutout.
b. After installation, verify that the tabs on the Wellsloks are
turned out to lock the warmer into the counter
c. Apply a thin bead of food-grade silicone sealant around the
ange to seal it to the counter.
d. Wellslok extension kits are available for installing warmers
in counter tops where the standard Wellslok would not
normally reach. The extension kit will adapt to counter tops
up to 1¾” thick.
ELECTRICAL INSTALLATION
1. Refer to the product nameplate. Verify the electrical service
power. Voltage and phase must match the nameplate
specications. Wiring the warmer to the wrong voltage can
severely damage the unit or cause noticeably decreased
performance.
2. Available electrical service amperage must meet or exceed the
specications listed on the specication sheet provided with the
warmer.
3. Warmer and control unit must be connected to an appropriate
building ground. Ground connection will be marked “GND” or
” “ .
NOTE: Wire gauge, insulation type and temperature rating , as
well as type, size and construction of conduit, must meet or exceed
applicable specications of local codes and of the National
Electrical Code.

jurisdictions may require an approved air gap or other
back-ow prevention device in the drain. It is the responsibility
of the plumber to determine such requirement, to provide and
properly install the required device.
3. For SS4D, SS8D and SS10D drainline units, the drain must be
2M-308034; Drop-In Round Warmer w/Innite Switch Control
attached with a union at the drain line tting. This is necessary
to provide for future maintenance of the heating element.
NOTE: Damage caused by
leaks due to improper
installation is NOT covered by
warranty.
CAUTION:
SHOCK HAZARD
The ground lug of this
appliance must be connected
to a suitable building ground.

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.
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.
Keep insets covered to
maintain food quality and
temperature.
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. 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. Innite 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.

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 miner-
als) 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.

Cleaning Guide. Contact NAFEM at :
