OPTIONAL BOOSTER PUMP (BPHF-MF-115):
An optional Booster Pump is necessary for installations with less than 40
psi tap water pressure.
RO production is directly dependent upon water pressure, so the
production rate may be dramatically increased by adding a Booster
Pump Kit. When installed between the Carbon Block filter and the RO
Membrane, the pressure may be increased up to 80 psi.This would double
the production rate if the starting household water pressure is 40 psi.
Higher water pressure not only increases the rate of production, it also
results in higher rejection rates for the RO Membrane. Higher rejection
rates mean less contaminants reach the DI stages, thereby extending the
life of your DI Cartridges which are a more expensive way to filter water
when compared to Reverse Osmosis Membranes.
If you are interested in installing a Booster Pump Kit on your RO/DI system
or if you have any questions regarding a Booster Pump Kit, please contact
SpectraPure Support.
FLOW RESTRICTORS AND TEST STRIPS:
These systems are supplied with TWO Flow Restrictors (FR) - RED and
GREEN. (See images on Page 9.) 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” on Page 18.) 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.
