Installation
1. Place the system in the desired location. Ensure adequate
clearance so the the bypass valve can be operated when
necessary. NOTE: System must be operated in a vertical
position. Do not lay it down during operation.

into the bypass valve are intended for a conventional softener
and are, therefore, the OPPOSITE of the correct OneFlow
operating flow.)
