PRO 48 Use & Care
Water Filtration System
The PRO 48 features a water filtration system that
supplies filtered water to the ice maker to produce great-
tasting 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 microbi-
ologically 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.
