OPERATION

WET OR DRY OPERATION for WARMERS

1. Carefully read the description of the warmer operation on the specification sheet.

2. a. Most warmers are designed for WET OR DRY operation, except AUTOFILL units..
   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. APW Wyott 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.

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.
DO NOT 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.
CAUTION: HOT SURFACE
Exposed surfaces can be hot to the touch and may cause burns.

AUTOFILL WARMERS

1. Autofill warmers sense water level by a sensor placed at the proper level. For manifolded autofill warmers, the water level sensor / fill tube is in one pan only.
2. Water fills the pan through an inlet tube. All other sections if manifolded, fill at the same time through the drain manifold.
3. The autofill function is active only when the thermostat for the pan with the water level sensor is turned ON .
4. Make sure the drain valve is fully closed before turning any t-stats ON.
5. DO NOT use autofill warmers in the dry mode. This may damage the water level sensor probe. NEVER turn the thermostat ON for the pan with the probe and fill tube unless the entire warmer unit is to be used in the wet mode.
6. Clean water level sensor daily to maintain water level in warmer.

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.

WARMERS WITH MANIFOLDED DRAIN

1. Water poured into any one section will seek the same water level with all sections on the manifold.
2. Make sure the drain valve is fully closed before filling warmer.
3. All units that are manifolded with the AUTOFILL unit, MUST be on the same elevation and completely level with each other to operate correctly.

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. 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 (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.
