User manual SCOTSMAN CM500

[. . . ] CM500 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 CM500 is an ice machine that produces cubed ice on 2 vertical cube freezing surfaces. The cubes fall as vertical strips of cubes into the ice storage bin where they break up into individual cubes. The CM500 automatically maintains the level of ice by turning on when the ice level falls, and switches off when the bin is full. [. . . ] If in an area of high mineral concentration in the water supply, clean water system 4 times a year. This ice machine will perform at its best when kept clean. There are two areas to keep clean: The water system including the water reservoir, distributor tube and evaporator surface; and the air cooled condenser filter and the condenser itself. Inlet Water Valve Screens If a restriction of incoming water is suspected, the screen on the inlet side of the water valve should be inspected & cleaned. Some models also have a strainer in the water line; the strainer screen should also be inspected for restricting minerals. 1. Remove the grill on the right side of the unit. Remove the filter pad from in front of the condenser. 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. Return the filter to its installed position. Do not operate the unit without the filter in place. 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. These will have to be dissolved by acid or the condenser replaced. Only a qualified service agent should attempt this type of service. Inlet Screen May Be Removed For Cleaning C, D and Early E Series Valve Later E Series Valve Inlet Screen Air Filter (air cooled only): December, 1992 Page 12 CM500 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. Once a week cleaning with soap and water, a hot water rinse and an air dry is a basic procedure. Every 90 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 two ounces of bleach to two gallons of water. Wipe all interior surfaces of the ice storage bin with the bleach and water. Mix a cleaning solution of 4 ounces of Scotsman Ice Machine Cleaner to 4 pints of hot (950F. -1100F. ) water. [. . . ] The low side pressure is much more important on an ice machine than is the high side. · If gauges must be used, use very short hoses. Minimal refrigerant discharged into the hoses equals minimal refrigerant discharged into the air. · If hi side pressure must be checked, use a quick connect at the end of the discharge hose to minimize the release of refrigerant, J/B Industries part number A33000 works well.
