The MaxCap
®
RODI system comes equipped with two Dual Inline TDS
monitors. The two TDS meters monitor every step in the purification
process. The IN probe of the left side meter shows the tap water TDS. The
OUT probe of the left-side meter shows the RO water TDS. The IN probe
of the right-side meter shows the TDS coming out of the MaxCap DI and
the OUT probe of the right-side meter shows the TDS of the final product
water (out of the SilicaBuster DI).
A pressure - operated Shutoff Valve and a Float Valve are provided for
convenient filling of a storage reservoir.
A Manual Flush Valve may be used to periodically rinse the accumulated
impurities and concentrated waste water from the surface of the RO
membrane to help increase the life of the membrane. If increased pressure
is needed or desired, use the BPHF-MF-115 Booster Pump Kit. This kit has
a 24VDC, 2.5A Power Supply.

FLOW RESTRICTORS AND TEST STRIPS:
These systems are supplied with TWO Flow Restrictors (FR) - RED and
GREEN. 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 removed FR and install the new FR with the same
orientation. (Refer to Page 9 for location of Flow Restrictor.)
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.
