CAUTION! FILTER FLUSH REQUIRED.
WL250's Water Treatment Systems are not supplied with filters. Filters should be
configured to optimize your system. Filters need to be configured and specified to do the job
given the local water conditions, usage, maintenance schedule, and placement restrictions.
In order for our filters to perform as represented and to provide the best quality water
possible, it is essential that filters be replaced periodically. The frequency of filter changes
depends upon your water quality and your water usage. For example, if there is a lot of
sediment and/or particles in your water, then you will have to change your filters more
frequently than a location with little to no sediment. Be sure to replace your filters whenever
