FLOW RESTRICTORS AND TEST STRIPS:
These systems are supplied with TWO Flow Restrictors (FR) - RED and
GREEN. See Pages 10 and 11. The RED FR (pre-installed) produces a preset
waste-to-product ratio of 3:1 and the optional GREEN FR has a 2:1 ratio.
Two Test Strips are provided to determine the Total Hardness (this is NOT
TDS) of your tap water. To test: Dip the colored end into a small tap water
sample for 3 seconds. Remove and do not shake. Wait for 20 seconds and
then match with the closest color block on the back of the package. Color
is stable for 1 minute.
If the Total Hardness is 180 or greater, you should keep the RED FR installed.
If the Total Hardness is less than 180, you may replace the RED FR with
the GREEN FR (see “Working with Push Fittings”). Be sure to note the
orientation of the small “plug” in the end of the removed FR and install the
new FR with the same orientation.
The RED FR has a waste-to-product ratio of 3:1, which will increase the
amount of water used, but also increase the lifetime of the RO membrane.
In hard water conditions, you may use the GREEN FR to save water, but
the RO membrane will not last as long, as it will plug up with hardness
much more quickly.
