Back-Flushing, cleaning & replacing the Pre-Filter EM Media
Cartridge
To properly maintain the Pre-Filter, it should be regularly back-flushed and cleaned (up
to 3 times) whenever an important reduction in the flow occurs. The disposable EM
Media Insert (17) shouldbe replaced when these procedures fail to restore acceptable
flow.
NOTE: The back-flushing process will require two people.
NEVER BACK-FLUSH THE NANOCERAM® CARTRIDGE!
BACK-FLUSHING THE NANOCERAM® CARTRIDGE WILL DAMAGE THE INTERNAL STRUCTURE
CAUSING THE FILTER TO BE INEFFECTIVE. BACK-FLUSHING THE NANOCERAM® CARTRIDGE
CAN ALSO CONTAMINATE THE MEDIA DOWNSTREAM OF NANOCERAM® MEDIA IF
DAMAGED, IT WILL NO LONGER FILTER THE WATER.
1. Make sure the water is turned off.
2. Remove the Back-Flush adapter (10) from the Inlet Assembly (9).
3. Remove the Inlet Assembly by turning it counterclockwise until it releases.
4. Remove the Pre-Filter Cartridge from the NanoCeram® Cartridge by turning it
counterclockwise until it releases.

5. Invert the Pre-Filter cartridge and place the Back-Flush Adaptor on the outlet
nipple of the Pre-Filter.
6. Insert the outlet nipple of the Inlet Assembly into the other end of the Back-Flush
Adapter and keep pressure on it. Hold the inverted Pre-Filter over the sink, a
bucket or some other receptacle that can hold at least 2 gallons (7.5 liters).
7. Have a second person turn on the water. When the water is turned on, there will
be a small amount of back pressure forcing the Inlet Assembly out of the Back-
Flush Adapter so you must hold the Inlet Assembly, Back-Flush Adapter, and Pre-
Filter together to keep pressure on it and keep them from coming apart.
8. Allow the water to run for 5 minutes, shake the cartridge and tap it against the
sink until the flow rate has increased
9. Open the housing by turning the top counterclockwise
