water to initially have some carbon fines (tiny black particles). It is also normal for the water to appear cloudy for
the first few days and is safe to drink. The cloudiness is caused by small air bubbles that get displaced from the filters. If
you leave the water standing for a few seconds, the cloudiness will disappear. Running the unit for extended periods of
time will NOT help.

*Note: Cartridge life is directly dependant on water conditions and volume of water filtered. Excessive sediment may cause
more frequent replacement. Contaminants reduced by these filters/cartridges are not necessarily in your water.
** Caution: It is highly recommended to replace sumps at least once every 5 years to prevent costly repairs or
possible water damage. Record date of installation of new sump at the bottom.
(a) Cleaning or replacing 1M Ceramic Cartridge
This cartridge is cleanable and reusable. The flow rate will gradually slow during use as
contaminants build up on the ceramic surface. The flow is restored by scrubbing the surface of
the cartridge as required using the abrasive cleaning pad (811-0) enclosed.

in palm of hand with nozzle up and gently scrub entire surface with
abrasive screen cleaner (811-0) provided under running water. Do not allow water to enter nozzle opening. DO
NOT USE SOAP OR DETERGENTS. Scrubbing removes trapped particulates along with part of the ceramic.
