FEATURES & OPERATING CONTROLS

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 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

1. “D” units (e.g. MOD-100D) have drains for each pan, with each pan having an individual drain valve.

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.
