• Temperature controller : After turning on for the delay time(2 minute), the compressor starts when cold room temperature ≥set temperature + hysteresis, and will be off when cold room temperature≤set temperature. To protect the compressor, it can re-start unless the time when the compressor stops every time is longer than the delay time.(3 minute)
  CAUTION—Setting the temperature control to the coldest setting may cause the eventually result in a warmer cabinet temperature.

• Maintenance: Please clean the cabinet with soft clothes timely. Before cleaning, MUST pull out the power plug. When the cabinet will not be used for a long time, disconnect the power cord then clean it. Please examine the wiring circuit before reusing it.Restart:

STAINLESS STEEL CARE AND CLEANING

•  Recommended cleaners for stainless steel
•  Soap, ammonia and detergent medallion applied with a soft cloth or sponge for routine cleaning.
•  Cameo,Talc,Zud First lmpression is for stubborn stains and discoloration. Rub in direction of polish lines.
•  Easy-off and De-Grease It oven aid are excellent for removals on all finishes for grease-fatty acides,blood and burnt-on foods.
•  Any good commercial detergent can be applied with a sponge or soft cloth to remove grease and oil.
• Benefit,Super Sheen,Sheila Shine are good for restoration/passivation.
  CAUTION: Do not use any steel wool, abrasive or chlorine based products to clean stainless steel surfaces.

STAINLESS STEEL ENEMIES

There are three basic items that can break down stainless steel’s passivity layer and allow corrosion to occur.

• Scratches from wire brushes, metal scrapers and steel pads are just a few examples of items that can be abrasive to stainless steel’s surface.
•  Deposits left on stainless steel can leave spots. Hard water can leave spots. Hard water that is heated can leave deposits if left to sit for too long. These deposits can cause the passive layer to break down and rust stainless steel. All deposits left from food prep or service should be removed as quickly as possible.
• Chlorides are present in table salt, food and water. Household and industrial cleaners are the worst type of chlorides to use.

8 Steps that can help prevent rust on stainless steel

• Use the correct cleaning tools. Use non-abrasive tools when cleaning your stainless steel products. The stainless steel’s passive layer will not be harmed by soft cloths and plastic scouring pads.

• Clean along the polish lines. Polish lines or grain are visible on some stainless steel.
  Always scrub parallel to visible lines. Use a plastic scouring pad or soft cloth when grain is not visible.

• Use alkaline, alkaline chlorinated or non-chloride containing cleaners. While many traditional cleaners are loaded with chlorides, the industry is providing an ever increasing choice of non-chloride cleaners. If unsure of chloride content contact the cleaner supplier.
  If present cleaner contains chlorides, ask for an alternative. Avoid cleaners containing quaternary salts as they can attack stainless steel causing pitting and rusting.

• Water treatment. To reduce deposits, use soft water whenever possible. Installation of certain filters can be an advantage. Contact a treatment specialist about proper water treatment.

• Maintain cleanliness of food equipment. Use cleaners at recommended strength(alkaline, alkaline chlorinated or non-chloride). Avoid buildup of hard stains by cleaning frequently.

• When using chlorinated cleaners you must rinse and wipe dry immediately. It is better to wipe standing cleaning agents and water as soon as possible. All stainless steel
  equipment to air dry. Oxygen helps maintain the passivity film on stainless steel.

•  Hydrochloric acid (muriatic acid) should never be used on stainless steel.

•  Regularly restore/passivate stainless steel.
