Phaser Pure Water System Operation and Maintenance Manual - 3
5. TDS (Total Dissolved Solids) Meter
Total Dissolved Solids are the minerals and salts within
source water that lead to spotting on glass as the water
evaporates. Your TDS meter measures the amount of
dissolved solids using the conductivity of the water. The
meter can test water before and after individual filters or
the entire system to determine how they are performing.
TDS levels are measured in parts per million (ppm).
Remove the cap from the TDS meter and fill with the
sample you wish to test. Push the “On” button on the
handheld TDS meter to get a TDS reading of the water
sample. A TDS reading of 0 – 10 is acceptable for
cleaning most windows, though specific conditions and
results may vary.
When measuring source water before pure water TDS
levels, it is important to rinse out any source water with
pure water to ensure accurate readings. Even a single
drop of source water will cause the pure water TDS
reading to appear higher than it actually is.
6. Using A WaterFed Pole
®
Once your Phaser system is hooked up, and you have
a WaterFed® pole connected to the unit, you’re ready
to clean windows.
Always begin by cleaning the top row or highest
windows first, including scrubbing the frames. Work
the WaterFed® pole up one side of the frames, across
the top, and back down the other side. Scrub the glass
in an up and down motion, moving the pole the entire
length of the glass with each stroke if possible. Return
the pole to the top of the window, and with a side to
side motion, allow rinse water to flow completely down
the surface of the glass.
Frame rinsing may not be required. If the height of the
glass and the weight of the pole allow for it, hold the
brush slightly off of the surface of the glass to rinse. If
this is not possible, move the pole side to side slowly
with the brush on the glass at the top, and let the water
flow down the glass to rinse.
bypass valve more will reduce the amount of pressure
that is used to produce pure water resulting in lower
flow rates at the brush. Closing the bypass valve will
increase the amount of pressure which will lead to
higher flow rates at the brush. Closing your valve so
that the flow of the bypass is roughly equal to the
flow of pure water exiting the system is a good place
to start. This will restrict flow for elevated system
pressure, but also allows waste water to exit your
membranes. When using a pump, open the bypass
valve fully to start then reduce flow for optimal
pressure. Do not exceed 120 PSI on your filters.
Flushing water through the RO filter after use will
remove excess minerals from the membrane. It is
recommended that your run your system with the
bypass valve fully open for a few minutes each time
you finish using your system to help clean out your
RO membranes and extend their life. See Shutdown
section of this manual for more details.
Once you have completed the top row or highest glass
on one side of the building, repeat these steps for each
tier or level of glass, working your way down. A good
initial scrubbing on the glass followed by a complete
rinse will ensure that the glass dries completely spot-
free.
Pure water is a great natural solvent for many soils.
In some cases, such as heavy soils, a pre-soak or
even a double scrub and rinse may be needed to
achieve optimal results. The agitation of the brush,
coupled with the flow of water through the brush when
scrubbing, should break down and suspend most soils,
readying them for complete removal via the rinse step.
As with any new procedure, practicing the use of your
WaterFed® pole is the best way to achieve optimal
results. Learn more about basic technique at www.
