Metering & Diagnostics - SpectraPure Single 90 Installation And Operating Manual

SpectraPure
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 pre-filters become clogged by dirt [tur-
bidity] 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. (See page 16 for DI exhaustion
details.)
USING THE PRESSURE GAUGE
The pressure gauge is used to monitor the condition of the Sediment and Carbon
Pre-Filters. 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 pre-
filters. 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 pre-filters 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 pre-filters by their color, always use the
pressure gauge to determine the condition of the pre-filters.
