[. . . ] of R-134a. December 1995 Page 2 CSWE1 Installation: Proper installation is a necessity, because an improper installation will cause operational problems that are NOT covered by any warranty. It is the customer's responsibility to contact a qualified installer. Proper electrical supply, water supply and floor drain must be available. [. . . ] Cut panels, making sure that the wood grain matches the direction of the cabinet wood grain. It is a good idea to cover the edges of a wood panel with moisture resistant sealant. Open the bin door and remove the two screws holding the handle to the top of the door, remove the handle. Remove the three screws that hold the lower panel assembly and the two screws at the top of the lower panel. Slide the metal panel and the spacer panels out of the lower panel assembly. 3. Slide the metal panel back into the lower panel assembly, slide the wood panel in front of the metal panel. Reattach the top of the panel with the two screws and replace the three screws that hold the lower panel assembly. December 1995 Page 6 CSWE1 What to expect: When the machine is on, and making ice the compressor, fan motor and water pump will be on. Periodically, the water pump and fan will stop and ice will be "harvested". Do NOT block the air flow in front of the machine. Water flows over an inclined freezing surface, and gradually freezes into a slab. The ice size thermostat measures the temperature of the freezing surface and the setting of that thermostat determines the thickness of the slab. During the ice release cycle, the ice slab slides down onto a hot wire cutter grid and, after the grid melts thru the ice, the individual cubes fall into the ice storage bin portion of the machine. The ice machine will continue to produce ice until the bin is full. Then the ice machine will shut down until the level of ice in the bin falls below the bin thermostat well. The ice storage bin is not refrigerated, so there will be some melting. This will vary with the temperature of the room where the ice machine is located. December 1995 Page 7 CSWE1 Maintenance: The water system, including the filter screen in the inlet water valve, needs to be cleaned periodically. Remove the two thumb screws, and slide the ice cutter grid forward, out of the two slots near the water pan. Prepare the cleaning solution by thoroughly mixing 2 ounces of Scotsman Ice Machine Cleaner into 2 quarts of hot (95oF - 115oF. ) water. An alternative solution is 6 ounces of powdered citric acid and 2 quarts of hot water. Scotsman ice machine cleaner contains acids. Pour cleaning solution into water pan and turn the switch to "Clean".
