Defrost Cycle – Automatic

• The system has an automatic defrost system which improves the energy efficiency of the unit and minimises temperature fluctuations
• After the unit is first switched ON, the first defrost cycle will occur automatically after 6 hours. If the unit is NOT turned OFF, the unit will defrost automatically 4 times per day or every 6 hours
• If air is not circulating properly, a manual defrost cycle can be made. Normal automatic defrost cycles will still occur every 6 hours even if a manual cycle has been run in between cycles. Check the electronic controller section for more information
• The defrost cycle terminates when the temperature of the evaporator coil rises to 6°C or after 30 minutes. Products will remain refrigerated during defrost cycle if the doors remain closed
• For changing of defrost cycle settings, contact Stoddart or an approved service technician

Corrosion Protection

• Stainless steel exhibits good resistance to corrosion however, if not properly maintained stainless steel can rust and/or corrode
• Any sign of mild rust and/or corrosion should be thoroughly cleaned with warm soapy water and dried as soon as possible
• NEVER use abrasive pads or cleaners for cleaning
• All metal surfaces should be checked while cleaning for damage, scuffs or scrapes as these can lead to rust and further damage to the product
• Mild rust and/or corrosion can be treated with a commercial cleaning agent that contains citric/oxalic/nitric/phosphoric acid. DO NOT use cleaning agents with chlorides or other harsh chemicals as this can cause corrosion. After treatment, wash with warm (not hot) soapy water and dry thoroughly
• Thoroughly wipe the surfaces dry after cleaning. DO NOT let water pool on the unit. Check crevices and folds for pooling
• When using, ensure all liquids and moisture is cleaned up straight away. Food liquids such as juices from vegetables and fruits should not be left on preparation surfaces
• DO NOT leave items on the stainless steel such as cutting boards, rubber mats and bottles

Surface Finish

• To protect the polished surface of the stainless steel, it should be dried using a clean dry soft cloth. A light oil can be applied to enhance the stainless steel surface, using a clean cloth apply the oil in the same direction as grained polished finish
• Some commercial stainless steel cleaners can leave residue or film on the metal; this may trap fine particles of food on the surface, thus deeming the surfaces not food safe

| IMPORTANT
