Filter Replacement - Sub-Zero 500 series Service Manual

Filter Replacement

How often should I change the Sub-Zero water filter?
You should change the filter cartridge at least once every twelve months. High sediment areas
may require more frequent filter replacements.
Replace the water filter cartridge when the filter indicator is lit or when water flow becomes
low.
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.
This system must be installed, operated, maintained and filters replaced as required in order for
the product to perform as advertised.
