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. The pressure will drop as the prefilters become clogged by dirt [turbidity]
from the tap water.
The digital TDS meter (left side) will provide a reliable means of evaluating the efficiency
of the RO membrane. This meter will indicate the tap water conductivity (“IN”) and the RO
water conductivity (“OUT”).
The difference between the two meter readings will be used to calculate the percentage of
rejection of the (TFC) RO membrane.
The Digital TDS meter (right side) will be used to determine the condition of the two stages
of the DI system. As the reading on the meter begin to rise above zero, the operator will be
alerted to the possibility that the DI system may have deteriorated past the exhaustion point
and that the DI cartridge(s) may need to be replaced.
Warning!!:
The DM1 TDS Meter does not detect the presence of CO2, 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.
USING THE PRESSURE GAUGE
The pressure gauge is used to monitor the condition of the Sediment and Carbon
Prefilters. With the Sediment and Carbon filters removed, the gauge will indicate
the “actual” tap water input pressure. When the prefilters are “new”, the pressure
shown on the gauge will be slightly less than the actual tap water pressure and as
the filters age, the pressure will drop due to the dirt that will collect in the prefilters.
When the pressure on the gauge drops below 40-PSI or as the filters collect
particulates and the pressure drop is greater than 15% to 20% of the normal water
pressure, the prefilters are in need of replacement.
NOTE: When the pressure on the pressure gauge drops below the normal
readings; do not assume that the sediment filter is the only cause. In some
geographical areas where the input water contains a high percentage
of very small micron particulates, the carbon filter may become clogged
before the sediment filter. (The filters may look new but still cause the
water pressure to drop). Do not judge the condition of the prefilters by
their color, always use the pressure gauge to determine the condition of
the prefilters.
