Filter Maintenance During Operation
Filter life will vary greatly based on the turbidity of source water.
Under optimal water conditions, a complete filter set should be
replaced every 6,000 gallons. Optimal water conditions are defined
as micro-biologically contaminated water sources with low levels of
sediment, turbidity or tannins. Increased levels of sediment,
turbidity or tannins will require more frequent changes of the
sediment filter identified by observable drops in water flow. When
you notice the flow rate decrease, follow the steps below to check
filters:
•
Disconnect all power from the unit.
•
Check Silt Screen for debris.
•
Replace the Sediment Filter in housing #1.
•
Restart unit and observe flow rate. If flow rate has not
improved, replace the Virus Media Filters.
