TROUBLESHOOTING WATER PURITY MONITOR
Some FAQs
Q
:Does monitor read “good” or “bad” when it is unplugged ?
A:The monitor reads “bad-RED” when it is unplugged.
Q:
What if the light switches between “green” and “red” between
successive depressions of the “push-to-test” water purity monitor?
A: Do not press the “push-to-test” button rapidly in quick
succession. Wait at least 5 minutes between two successive
depressions of the button for an accurate reading.
Q
:How should the probe be mounted for an accurate reading?
A:The probe should be mounted VERTICALLY, at the bottom of
the T.
Q
:How long does the battery last ?
A:1 year approx.
Q
:How do you determine if the battery needs replacement ?
A:Depressing “push-to-test” button does not give any light.
Q
: If the monitor shows a red light, what does it mean?
A: It means that either the membrane is bad OR either the probe
or monitor is faulty.
Q
:How do you determine if the probe or monitor is faulty?
A:Refer to the troubleshooting guide.
IMPORTANT NOTE: ONLY USE ALKALINE BATTERIES.
Other Batteries will cause erroneous readings.

SYSTEM DESCRIPTION
The SpectraPlus 2000™ system is a five stage reverse osmosis de-ionization
system.
1. First, the incoming feed water is passed through a 0.5 micron
Micro-Tec sediment pre-filter. This filter is required to remove
excess turbidity (particulate matter) that may cause the carbon
block filter to plug.
2. The second stage of filtration is a 0.5 micron carbon block pre-
filter. This filter removes organics and chlorine from the feed
water that can damage the membrane.
3. The third filtration stage of the system is a high rejection thin
film composite (TFC) reverse osmosis membrane. It removes over
98% of most inorganic salts, all micro-organisms and organics
above 100 diatoms molecular weight.
4. The fourth stage filter is a color changing, strong base anion
cartridge. The anion exchange resin removes all negative ions
and replaces them with hydroxyl ions.
5. The fifth stage of the system is a Dual Layer Deionization
cartridge. This cartridge removes almost all minerals and
organics that may pass through the membrane, producing
laboratory grade water with >18 Mohm / cm resistivity. The
result of processing water through all five stages is ultra-high
purity “mineral-free water”. This System is also available with a
semi-conductor-grade mixed-bed resin cartridge for more critical
applications.
The SpectraPlus 2000™ system comes equipped with a water purity monitor that
indicates when the final DI stage(housing position #4) is exhausted.
This super-capacity RO/DI system consists of newly developed color-indicating DI
resin cartridges with twice as much phosphates/silica removal resin as in previous
designs.
Maintenance and trouble-shooting procedures have been made easy and effec-
tive with a combination of the DI purity monitor, color-indicating DI resins, and a
built-in pressure gauge. It is recommended that you keep replacement cartridges
on hand, ready to install as soon as the monitor indicates that the cartridge in use
is exhausted.
