METERING AND DIAGNOSTICS:
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 prefilters.
USING THE PRESSURE GAUGE
The pressure gauge is used to monitor the condition of the Sediment and Carbon
Prefilters
(not the RO Membrane)
. When the filters are new, the gauge will
indicate the actual available house water pressure. As the filters collect particulates,
the pressure will begin to drop. A 15 -20% (or more) drop in pressure would
indicate that the prefilters are in need of replacement.
USING THE THREE-PROBE TDS METER (TRM-1 METER)
The digital TDS meter (three probe) will provide a reliable means of evaluating the
performance of the RO membrane and the Deionization Cartridge. The numbers
from the three probe readings can be used to calculate the percentage of rejection
of the RO membrane and the exhaustion point of the DI Cartridge.
Procedure for testing the RO Membrane:
1. Follow the instructions on page 11.
Procedure for testing the Deionization Cartridge:
1. When the reading on the probe (set to “Line 3”) displays “001”, it is time to replace
the DI cartridge. The system must be running when taking this reading.
Warning!!
The TRM -1 TDS Meter does not detect the presence of CO
2
, silica, organic
contaminants or microorganisms, 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.
