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.

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.

2. Remove the Back-Flush adapter (10) from the Inlet Assembly (9).
3. Remove the Inlet Assembly by turning it counterclockwise until it
releases.
