Preheating

Preheat the Thermodyne cabinet when first used for the day or whenever the unit is cold. Preheating takes approximately 30 minutes at which time the temperature set point and the actual temperature will display the same temperature. If the cabinet has door(s), keep the doors closed during the preheat cycle.

FLUID REPLENISHMENT

CAUTION: Use only supplied Thermodyne

Heat Transfer Fluid.

: Disconnect the electrical power to the hot well and perform

LOCKOUT/TAGOUT procedure.

: Drain the hot water for the hot wells before beginning any procedure that requires lifting the hot wells to gain access to the power head.

CAUTION: The cabinet and the hot well may be hot, allow them to cool before beginning this procedure.

1. Move the Hot Well power ON/OFF switch to its OFF position. DO NOT turn the oven off.

2. Drain all water from the hot wells.

CLEANING AND MAINTENANCE

ELECTRICAL LOCKOUT/TAGOUT

PROCEDURE

STAINLESS STEEL CARE

Cleaning

: Before performing any cleaning or maintenance that involves electrical connection or disconnection and/or exposure to electrical components, always follow the Electrical LOCKOUT/

TAGOUT Procedure. Disconnect all circuits.

Failure to comply can cause property damage, injury or death.

The Electrical LOCKOUT/TAGOUT Procedure is used to protect personnel working on an electrical appliance. Before performing any maintenance or service that requires exposure to electrical components, follow these steps:

1. In electrical box, place appliance circuit breaker into OFF position.

2. Place a lock or other device on electrical box cover to prevent someone from placing circuit breaker ON.

3. Place a tag on electrical box cover to indicate that appliance has been disconnected for service and power should not be restored until tag is removed by maintenance personnel.

4. Disconnect appliance power cord from electrical outlet.

5. Place a tag on the cord to indicate that unit has been disconnected for service and power should not be restored until tag is removed by maintenance personnel.

Stainless steel contains 70-80% iron, which will rust if not properly maintained. It also contains 12-

30% chromium, which forms an invisible passive, protective film that shields against corrosion. If the film remains intact, the stainless steel will remain intact. However, if the film is damaged, the stainless steel can break down and rust. To prevent stainless steel breakdown, follow these steps:

CAUTION: Never use any metal tools.

Scrapers, files, wire brushes or scouring pads (except for stainless steel scouring pads) will mar the surface.

CAUTION: Never use steel wool, which will leave behind particles that rust.

CAUTION: Never use acid-based or chloridecontaining cleaning solutions, which will break down the protective film.

CAUTION: Never rub in a circular motion.

CAUTION: Never leave any food products or salt on the surface. Many foods are acidic.

Salt contains chloride.

For routine cleaning, use warm water, mild soap or detergent and a sponge or soft cloth.

For heavy-duty cleaning, use warm water, a degreaser and a plastic, stainless steel or Scotch-

Brite pad.

Always rinse thoroughly. Always rub gently in the direction of the steel grain.

WHEN TO CLEAN

It is recommended that all stainless steel equipment be cleaned on a regular basis. Any piece of stainless steel equipment that is soiled should be cleaned daily to ensure the long life of the equipment. Routine cleaning will also lessen stainless steel abrasion.

Preserving & Restoring

Special stainless steel polishing cleaners can preserve and restore the protective film.

Preserve the life of stainless steel with a regular application of a high quality stainless steel polishing cleaner as a final step to daily cleaning.

— 12 —

If signs of breakdown appear, restore the stainless steel surface. First, thoroughly clean, rinse and dry the surface. Then, on a daily basis, apply a high-quality stainless steel polish according to manufacturer’s instructions.

Heat Tint

Darkened areas, called heat tint, may appear on stainless steel exposed to excessive heat, which causes the protective film to thicken. It is unsightly but is not a sign of permanent damage.

To remove heat tint, follow the routine cleaning procedure. S tubborn heat tint will require heavyduty cleaning.

To reduce heat tint, limit the exposure of equipment to excessive heat.

product deposits. In the event heavy deposits occur that are difficult to remove with ordinary cleaning procedures, stronger chemical cleaning agents may be applied if the products are intended for food service use and are also compatible with hard coat anodized aluminum surfaces. When using these stronger solvents, it is very important that heat transfer shelves are rinsed thoroughly with clean potable water after cleaning. Be sure to remove all traces of the cleaning agent. Between the regular scheduled cleaning, wipe off the anodized aluminum surfaces periodically with a clean damp cloth.

CLEANING HEAT TRANSFER PLATES

The Thermodyne unit operates on the principle of conduction, rather than convection. Therefore, it is very important to keep the heat transfer shelves clean, so heat transfer may take place with maximum efficiency. It is also very important to keep the bottom contact surfaces of pots and pans as clean as possible to ensure even and complete heat transfer. The surface and flat coating of the thermal heat transfer shelf is extremely hard, but will react with strong caustic cleaning solutions and deteriorate.

CAUTION: Most concentrated soaps and ammonia cleaners are too caustic to be used on the Thermodyne unit.

If the coating is destroyed, the heat transfer shelves will lose their non-stick properties and their surface hardness.

The cleaners should always be used at the recommended concentrations. In the case of dry powders, the powders must not be placed directly on the surface of the heat transfer plate. Care must be taken not to scratch the shelf surfaces when using brushes or pads. If harsh scouring is needed, use a nylon type scouring pad. NEVER use steel wool.

It is recommended that a weekly cleaning schedule be followed to avoid the buildup of heavy food

— 13 —

CLEANING DOOR GASKETS

Clean the gasket-sealing surface of the Thermodyne doors to remove food product acids for maximum gasket life. Do not use any solvents or sharp instruments as these will damage the gasket.

Wash with a cloth moistened in a solution of mild detergent and warm water. Rinse with a fresh cloth moistened with warm water to remove all traces of detergent. Wipe dry with a clean cloth. Never apply food product oils or petroleum lubricants directly to the door gasket as these will reduce gasket life.

CHANGING FLUID

NOTICE: The Thermodyne Heat Transfer Fluid has lubricating additives, anticorrosion additives, and heat transfer properties that may decrease with the passing of time. Thermodyne Heat Transfer

Fluid will protect the unit indefinitely if the fluid is changed on an annual basis.

CAUTION: The following procedure is to be performed by a qualified service technician only.

: Before removing any sheet metal panels or servicing this equipment, always perform the Electrical LOCKOUT/

TAGOUT Procedure. Be sure all circuits are disconnected. Failure to comply with this procedure can cause property damage, injury or death.

1. Move Power ON/OFF switches to the OFF position and perform LOCKOUT/TAGOUT procedures.

2. Drain all water from the hot wells.
