PRO 48 Use & Care 10 Water Filtration System The PRO 48 features a water filtration system that supplies filtered water to the ice maker to produce greattasting ice. The water filter has been factory installed behind the grille assembly. It is important that the operation, maintenance and filter replacement requirements be carried out as scheduled. Refer to the following information on the water filter cartridge monitor. IMPORTANT NOTE: If the unit has been turned off or the ice maker disabled for one month or longer, the water filter cartridge should be replaced once the unit and ice maker are back in operation. IMPORTANT NOTE: Do not use with water that is microbiologically unsafe or of unknown water quality without adequate disinfection before or after the system. Systems certified for cyst reduction may be used on disinfected waters that may contain filterable cysts. Refer to the performance data on page 25 for additional information regarding the water filtration system. WATER FILTER CARTRIDGE MONITOR The water filter cartridge is designed to last for up to one year of continuous use of the ice maker. The electronic control system monitors the life of the water filter cartridge and indicates when it needs to be replaced. An indicator that reads 'REPLACE FILTER' will be visible in the left side exterior temperature display. Follow steps to replace the water filter cartridge on the following page. Once the filter cartridge has been replaced, the control automatically resets the water filter life monitor and the 'REPLACE FILTER' indicator will no longer be displayed. Although it is designed to last for up to one year of use, the actual life of the filter cartridge may vary with water supply conditions. Therefore, it is recommended that the filter cartridge be replaced when the 'REPLACE FILTER' indicator is displayed or if the ice cubes become hollow or smaller. IMPORTANT NOTE: The warranty for the water filter cartridge supplied with the unit only covers defects in materials or workmanship and not replacement due to normal use.
