Installation Instructions
Standard Installation (Forward Flush only)
A standard installation clears the membrane periodically by opening a drain port, and allowing the feed stream
flow in its normal direction, but at a faster rate. The flow goes in and out of the end of the fiber instead of through
the membrane, and the foulant is cleaned off the membrane and out of the unit to drain.
Connect the FreshPoint™ to the household plumbing supply as shown in Figure 1. It is recommended that the
plumbing include a system bypass for future service. A 200 um sediment pre-filter is recommended. For ease of
membrane element replacement, unions are recommended as indicated on Figure 1.
NOTE: Installations without a pressure tank may experience drops in pressure/flow to the home during a
flush cycle.
