User manual SCOTSMAN CME500

[. . . ] CME500 Introduction To the owner or user: This service manual is intended to provide you, and the maintenance or service technician, with the information needed to install, start up, clean, maintain and repair this product. The CME500 is an ice machine that produces cubed ice on 4 vertical cube freezing surfaces. The ice falls as vertical strips of cubes into the ice storage bin where they break up into individual cubes. The CME500 automatically maintains the level of ice by turning on when the ice level falls, and switches off when the bin is full. [. . . ] Some models also have a strainer in the water line; the strainer screen should also be inspected for restricting minerals. Wash the surface of the filter off with cold water, or, if torn or so dirty it can't be cleaned, replace with a new filter. Note: If the unit has been operated without the filter in place, the fins of the condenser will become fouled with dirt, and must be cleaned. A vacuum cleaner with a soft brush attachment will extract most loose dust stuck to the surface of the condenser fins. If there is any doubt about dirt inside the fins of the condenser, the cabinet should be removed and a qualified service agent should clean the condenser. Water cooled units: The water cooled condenser may, over time and under certain water conditions, become internally restricted by minerals. Only a qualified service agent should attempt this type of service. Inlet Water Valve Inlet Screen August 1994 Page 12 CME500 Cleaning: Ice Storage Bin The interior liner of the bin is in contact with a food product: ice. The storage bin must be cleaned regularly to maintain a sanitary environment. Every 30 days, the liner should be sanitized with a commercial ice machine sanitizer, according to the directions of the sanitizer, or with a solution of household bleach and water: 1. Mix the bleach and water using the ratio of one ounce of bleach to two gallons of water. Wipe all interior surfaces of the ice storage bin with the bleach and water. Note: If the ice baffle was removed from the bin during cleaning it must be reinstalled in the bin. Mix a cleaning solution of 4 ounces of Scotsman Ice Machine Cleaner to 4 pints of hot (950F. -1100F. ) water. Using rubber gloves, dip a nylon scouring pad into the cleaning solution and scrub the scale off the liner. After the scale has been removed, rinse all surfaces inside the bin with clean, potable water. Stainless Steel Components Inside Bin The stainless steel parts in the bin also require periodic cleaning. Chemicals in the water supply, such as chlorine, cause brown stains to appear on the surface of the stainless steel parts. General Cleaning - staining is usually removed by washing the parts with ordinary cleaning powder such as Bon-Ami or Copper-Glo and water. It can be removed from the water supply by using a charcoal or activated carbon water filter to treat the water to the ice machine. Exterior Cabinet Cleaning: The exterior cabinet may be cleaned by scrubbing with soap and water. A nylon type brush may be used to scrub stubborn deposits.
