There are two ways Note: Slope-front bins must have an internal baffle. water carries the impurities: suspended and Scotsman HTB555 and BH550 have the required dissolved. Suspended solids can be filtered out. baffle. Baffle must be approximately in the position Dissolved solids must be diluted or treated. Water shown in the diagram below. filters are recommended to remove suspended Baffle solids. Some filters also have treatment in them for dissolved solids. Check with a water treatment service for a recommendation. 4.0" 12.0" Cube Ice machines use more water than what ends up in the bin as ice. While most water is used during ice making, a portion is designed to "rinse" out the water system to keep hard water scale from clogging up the machine. That water rinse, combined with water filters, prolongs the times between needed water system cleaning. Service Technicians: All models covered here come set from the factory with at a "Standard" water rinse. Standard water rinse is designed to be compatible with typical water conditions. The machine may be adjusted to a different water rinse after start up. If the prior ice machine worked acceptably well with the local water conditions, leave the machine at the factory setting. If severe water conditions are present, and water filters do not solve the problem acceptably, adjust the machine to use more water. If water conditions are excellent, adjust the machine to use less water. See the Adjustments section. Side View Electrical: Check the nameplate for electrical requirements. The nameplate is located on the back of the ice machine. If the information on the nameplate is different from other published information, go by the nameplate data. While the model and serial number are on Note: Water use adjustments are customer the nameplate, a serial number plate convenience adjustments; they are NOT factory defects and are NOT covered by warranty. is located at the front of the machine, behind the front panel and to the right of the purge valve.

See page 11 for details. 2. Lift up at the front edge and push the top panel Unpacking and Assembly: back until it releases from the tabs connecting it to the back panel. Begin with unpacking the ice storage bin. Remove the carton, and using part of the carton as a cushion, tip the bin on its back to remove the skid and attach the legs or casters. Note: Stacked applications may not use casters. Return the bin to an upright position. Check the bin top gasket for gaps and tears, fill any in with food grade sealant prior to placing the ice machine on the bin. Note: If recycling a prior bin, be sure that the bin top gasket is in good condition or seal the ice machine to the bin with food grade sealant. Level the top edge of the bin front to back and left to right. If the ice machine has not been unpacked, do so now. Remove the carton from the skid. Remove shipping straps. Remove the front panels and all packaging materials. After all packing materials have been removed from the ice machine, lift or hoist the machine onto the bin. Align the sides and back of the machine with the sides and back of the bin. Secure the ice machine to the bin with the two metal straps and 4 bolts provided. 3. Remove two screws at the front of each side panel, and pull them forward until they release from the tabs connecting them to the back panel.
