Instructions For Use:
A complete list of installation, set up guide and important safety instructions is included with your purchase. Be sure to read and follow all safety precautions and keep instructions on hand for future reference. Remove cover from filter. Remove used cartridge from bio-holster by pushing down gently on the holster and pulling the tab on the cartridge upwards. Discard used filter cartridge. Bio-holster should not be removed or cleaned, as it contains living beneficial bacteria. Rinse new cartridge under cold water to remove carbon dust. Insert new cartridge into bio-holster by aligning the key slot on the cartridge with the key slot on the biological grid. Replace cover on filter. NOTE: Cover will not fit properly if the filter cartridge is installed incorrectly. Cartridges should be replaced when water begins to enter the filter bypass and/or the cartridge becomes clogged. Cartridges should be replaced every 4-6 weeks.
