After the new filter cartridge is installed, discard the first full bucket of ice 
produced. This will help clean the water system and clear air from the line. Allow 
24 hours before discarding the first bucket of ice. 
For dispenser models, the water line is typically purged before connecting to the 
unit, however the first several glasses of water should be discarded after replacing 
the filter.
