The following preventive maintenance checks will help keep Hoshizaki KM-series cubers dependable and serviceable for many years. Clean the removable air filter. Service the water filter and check the water valve screen. Visually inspect the loose wires, oil spots, water drips, etcetera. Clean the exterior with a soft cloth and neutral cleaner. Clean and sanitize the water system and bin. Annual cleaning and sanitizing of the water system is recommended. More frequent cleaning may be required depending on local water conditions. Cleaning the water system is an easy procedure with the KM cuber. The complete cleaning instructions are listed on the reverse side of the front panel. First, drain the reservoir by removing the stand pipe on M-models or drain plug on S-series models. Mix the cleaning solution according to directions on the panel and then pour it into the reservoir. Hoshizaki recommends Hoshizaki Scale Away or Economics Lab’s Lime Away. However, the durable stainless steel evaporator plate will not be harmed by any commercialized machine cleaner. Set the control switch to wash and turn the evaporator cleaning valve to the “open” or “wash” position. With these controls set, the pump circulates cleaner inside and outside of the evaporator plates. Since the inside pass does not collect heavy mineral deposits, allow the cleaner to circulate through the cleaning valve for about 5 minutes. Then, turn the cleaning valve back to the horizontal position. This allows all the cleaner to flow on the outside of the plates where more cleaning is needed. Once the flat surface is clean, pull the distributor tubes out 3/8” to allow the cleaner to flow down the evaporator ribs. When cleaning is completed, flush the rudder system thoroughly with clean, fresh water. Turn the control switch to the “ice” position. The ice maker will restart in the normal sequence of operation. The same procedure should be used to sanitize the water system. Mix the commercial ice machine sanitizer as per directions on the panel or a 5 1/4 percent sodium chloride solution. Circulate this solution for 5-10 minutes over the evaporator surface and ribs. Flush the solution from the machine with clean, fresh water before restarting the ice maker.
