Maintaining the Pre-Filter Cartridge

Back-Flushing
You should back-flush the Pre-Filter (up to three times) when a significant reduction
in flow occurs. The disposable EM Media Insert should be replaced if back-flushing the
Pre-Filter fails to restore acceptable flow.
IMPORTANT: NEVER BACK-FLUSH THE NANOCERAM® CARTRIDGE.
Back-flushing the NanoCeram® Cartridge will damage its internal structure, causing
the filter to become ineffective. Back-flushing can also contaminate the downstream
media of the NanoCeram® so that it will no longer filter properly.
Note: The back-flushing process requires two people.
1. Make sure the water is turned off.
2. Remove the back-flow adapter from the Inlet Assembly.
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-Flow 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
