A. INFINITE SWITCH
1. On INFINITE SWITCH CONTROLLED warmers, power is applied to the heating element based on the control knob position and the amount of energy consumed.
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: Since the infinite switch is basically a timing device, no temperature sensing component is required.
1. Countertop warmers may be equipped with adjustable legs.
These legs allow for: a. leveling the warmer b. ventilation around the warmer, and c. cleaning under the warmer.
2. Adjustable legs are supplied with the warmer, these legs
MUST be properly installed before the warmer is placed into operation. See page 11 for alternate legs.

OPERATION
WET OR DRY OPERATION
1. Carefully read the description of the warmer operation on the specification sheet.
2. 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.
3. a. Most warmers are designed for WET OR DRY operation. b. Warmers may be used wet, or may be used dry. However 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.
4. Damage caused by allowing a wet-operation warmer to run dry, 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.
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

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:
• 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.

Cleaning Guide. Contact NAFEM at :
