This SpectraPure purification system has been fully equipped with sufficient
instrumentation to make monitoring and troubleshooting an easy process. The
provided pressure gauge is used to determine the tap water pressure and to
evaluate the condition of the sediment and carbon pre-filters.
USING THE PRESSURE GAUGE
The pressure gauge is used to monitor the condition of the Sediment and Carbon
Pre-Filters
(not the RO Membrane)
. When the filters are new, the gauge will
indicate the actual available house water pressure. As the filters collect particu-
lates, the pressure will begin to drop. A 15-20% (or more) drop in pressure would
indicate that the pre-filters are in need of replacement.
USING THE DUAL PROBE TDS METER (DM1 METER)
The digital TDS meter (dual probe) will provide a reliable means of evaluating the
performance of the RO membrane and the De-Ionization Cartridge. The num-
bers from the two probe readings can be used to calculate the
percentage of rejection of the (TFC) RO membrane and the exhaustion point of
the DI Cartridge(s).
Procedure for testing the RO Membrane:
1. Follow the instructions on page 15 & use the calculations located on
page
19-20.
Procedure for testing the De-Ionized Cartridge:
1. When the reading on the probe (set to “OUT”) displays “001”, it is time to
replace the DI cartridge.
Warning!!:
The DM1 TDS Meter does not detect the presence of CO2, silica, organic
contaminants or micro-organisms, nor should it be used as a medical or scientific
instrument. It should be used as an indicator or guide only, and does not imply
water safe for human consumption. No application other than monitoring the
electrical conductivity of water is expressed or implied.
