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.

5. Loosen the hinges on the unit.

CAUTION

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

CAUTION

Never use acid-based or chloride-containing cleaning solutions, which will break down the protective film.

CAUTION

Never rub in a circular motion.

Hinge

Screws

Figure 29: Location of Hinge Screws

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 heavyduty 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.

Preserving & Restoring

6. Reattach the door/s to the loosened hinges.

7. Close the door/s and align them in the closed position.

8. Tighten the hinge screws.

9. Make sure the doors open and close properly.

10. Attach the Side Panels.

11. Restore the unit to its power source.

Cleaning

STAINLESS STEEL CARE

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.

— 26 —

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.

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. Stubborn heat tint will require heavyduty cleaning.

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