The Solo Pure Water System Operation and Maintenance Manual - 1
Overview
Thank you for purchasing the Solo Pure Water System!
With proper care, this unit will provide you with years
of trouble free service. This system was designed with
professional window cleaners in mind. The Solo will
help you clean faster, safer, and better than ever before,
leaving spot free results that you and your customers
will love!
The Solo contains an RO membrane that will remove
over 90% of the dissolved solids from source water.
It also has enough pre-lter media inside the same
housing to protect the RO from chlorine and biological
fouling for the duration of its lifespan. With proper care
and maintenance the Solo System should be able
to process 100,000 gallons on most water sources.
Failure to follow the instructions in this manual will
reduce the lifespan of the system.
Congratulations on your purchase.

3. Initial Setup
1. Attach bypass hose to the tting on the side of
The Solo system.
2. Open valve on bpass hose fully.
3. Attach shut-o valve to The Solo system outlet.
4. Attach pole tubing to quick connect shut o and
turn to open position.
5. Attach source hose to water source and the other
end inlet of The Solo system.
6. Turn on source water.
7. Elevate the outlet side of the unit and rotate so
bypass is facing upward until air has been purged
from the RO housing through the bypass line.
Failure to bleed the air out of the system can result
in lower production and possible damage to the
lter housings. Trapped air may also result in the
plastic overheating and pressure rating of the RO
housing dropping. Setting up your system up out
of direct sunlight on hot days will also help protect
the plastic RO housing from heat damage.
8. Once the air has been purged out of the lters,
close the bypass valve partially to begin producing
pure water. Do not close o ow through the
bypass line while usingthe system (some bypass
water should always be owing out). Your bypass
hose assembly (WF2200-BHA) is manufactured so
that it can’t be completely closed. Never plug the
end of your bypass while in operation. See Bypass
Valve Operation section below for more information.
9. Start cleaning windows.
2. TDS (Total Dissolved Solids) Meter
Total Dissolved Solids (TDS) 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 the system to
determine how it is performing. TDS levels are measured
in parts per million (ppm).
Remove the cap from the TDS meter and ll 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 specic conditions and
results may vary.
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.
Your TDS meter also has a thermometer which reads
temperature. This can allow you to monitor the
temperature of your feed water. Running your system at
feed water temperatures of less than 10 °C (50 °F) will
result in low ow exiting the system. RO membranes
require more pressure to create the same amount
of clean water as the temperature of the water gets
colder. A pump can help to compensate for low source
water temperatures. Do not let the system freeze when
operating in lower temperatures.

5. Hooking Up To Water Source
Locate an external water source. Attach one end of
the feed hose (not supplied) to the water source. Open
the faucet at the building and make sure all air is out
of your source hose. Turn o water and attach to inlet
of The Solo System. A 1/2” garden hose is preferred.
Open bypass valve fully and turn on source water.
Once the air in the lters has left the bypass line, adjust
valve to desired ow rate. Open the shut-o valve
between the hose and the pole to allow water to ow
through the pole and wash glass. Do not drink pure
water made from your system. If using a pump, wait
for water to ow from brush before turning the pump
on. Do not exceed 120 PSI.
6. Bypass Valve Operation
The system comes with a bypass hose and valve that
control the amount of water leaving The Solo System.
RO membrane lters use the bypass ow to remove
concentrated dissolved solids from the lter. There
should always be water owing out of the bypass
hose. Inadequate bypass ow will result in fouling and
possibly damage the RO lter.
The water coming out of the bypass hose may initially
appear milky. This milky appearance is actually small
air bubbles being pushed out of the lter housing
through the bypass line.
The bypass valve on your Solo System is drilled out so
that enough bypass ow should still exit your system
when the valve is fully closed. On some high TDS
source water or when operating with a pump, you may
want to open the valve to allow more water to exit the
system as bypass water. Your bypass ow should be
roughly equal to the ow of pure water leaving the
system.
When using a pump, open the bypass valve fully to
start then reduce ow for optimal pressure. Do not
exceed 120 PSI on your lters.
Flushing water through the RO lter after use will
remove excess minerals from the membrane. It is
recommended that you run your system with the
bypass valve fully open for 3-5 minutes each time
you nish using your system to help clean out your
RO membrane and extend its life. See Shutdown
section of this manual for more details.
4. Adding Optional Filters
The Solo System is designed to have everything
needed to purify most municipal water sources to
acceptable levels for window cleaning, all in one sealed
housing. For very hard water sources, an external DI
lter may be required, after the system, to polish o the
pure water exiting the system in cases of source water
with a high content of total dissolved solids (TDS) or
for jobs which require 0 part per million pure water to
clean.
The Solo system is not designed to be run using well or
reclaimed water. This system was designed specically
to operate on municipal water sources. Sediment or
other special lters can be added before the system to
minimise the eects of well or reclaimed water. Using
microbially unsafe source water will reduce the lifespan
of the system and may cause biologic fouling of the
membrane.

10. Maintenance
1. If using a pump, shut o the pump before turning o
supply water.
2. Close the shut o valve to the pole. Open bypass
valve to fully open position and ush out the system
for 3-5 minutes.
3. Turn supply water o.
4. Disconnect the water line. Make system water right
by connecting bypass hose to inlet and closing the
shut-o valve.
9. Shutdown
8. Soap Residue
Getting spotting when your TDS levels are below 10?
A common issue encountered when transitioning
buildings from traditional window cleaning methods
to pure water cleaning is soap residue. After the initial
cleaning with pure water, small white or gray spots and
runs may be seen on the glass after drying. Most often
this is soap and or detergent residue left behind by
previous traditional cleanings and brought out of the
pores of the glass by the pure water cleaning process.
The soap can take up to 30 minutes to dissolve if it
has been baked on or pushed into seals and frames.
Soaking the glass 15-20 minutes before performing
a normal agitation and rinse cycle will remove soap
spotting. Repeat agitation and rinse if the spots persist.
Your Solo system requires little maintenance to
operate at peak performance. As stated above,
ushing the RO membrane and having sucient
bypass ow is essential to achieving maximum RO
lifespan.
RO membranes have the potential to process 100,000
gallons of water when properly maintained. To test the
health of your RO membrane compare the TDS levels
of the source water to the level of pure water leaving
the system. For example, 100 TDS source water with
10 TDS leaving the system indicates 90% rejection.
When rejection rate climbs above required levels for
your cleaning application it is generally time to buy a
new system. Adding a DI lter after the system can
allow you to keep an older Solo system in service
longer.
7. Using A WaterFed Pole
®
Once your Solo 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 rst, 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 ow 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 o 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
ow down the glass to rinse.
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 ow 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

12. Troubleshooting
11. Storage
1. Low tap pressure is one of the most common causes
of low ow of pure water. Source water pressure is the
primary driver of system performance. Even sources that
appear to have plenty of ow out of the tap may not have
enough PSI to push water through the RO membrane.
Ensure that the tap pressure is sucient using a pressure
gauge ( TA-PG Sold Separately). Trying a dierent
source may lead to better performance. Also check all
hoses (incoming and outowing) for kinks or blockages,
Do not allow the lters or system to freeze. Failure to
do so could result in damage to your Solo system. Do
not allow the RO lter to dry out. A dry RO membrane
will develop cracks which allow more dissolved solids
to pass through. abc recommends that you run water
through your system once every 2 weeks or so, not only
to help keep your lters moist but to also wash out any
microorganisms that might try to grow in your lters. The
Solo needs to stay moist but does not need to be full of
water.
abc strongly recommends ushing out the system once
every 2-4 weeks to ensure the maximum lifespan of the
lter. This will ensure that the lter membrane does not
dry out and will reduce the chance that biological growth
will foul the lter elements while in storage.
If periodic ushing is not feasible, we recommend that
users seal the system by attaching the bypass hose to
the system inlet and then attach a closed shut o valve
to the system outlet. This will reduce the chance that
the lter dries out when in storage. Wrap lters tightly in
plastic wrap or plastic bags and then seal with tape.
Do not allow the system to dry out.
Store system indoors over the winter. Do not allow it to
freeze. Failure to do so could result in damage to your
Solo system. After the system has been stored this way,
it will need to be ushed thoroughly before use. Leaving
the system sealed for extended periods of time can
lead to biological fouling, which is why we recommend
periodic ushing.
Storage - Short Term (2-4 Weeks)
Low Pure Water Flow Out Of The Brush
Storage - Long Term (Winterizing)
especially hose reels that are wound too tight. Trying
a larger diameter hose (½”) or a shorter hose length
between the system and the tap can also improve ow.
Adding a pump, such as the ABC boost pump (WF1000-
BP Sold Separately), can help compensate for low source
pressure. Do not exceed 120 PSI when using a pump.
2. Mineral fouling of the RO membrane will lead to
reduced pure water production from your system.
Processing water through the RO membrane without
enough (or any) bypass ow will lead to increasing
mineral concentration within the RO housing. In minor
cases, this will result in a temporary drop in production
from the RO membrane. Flushing the excess minerals
from the housing will return the lter to normal production
rates if no fouling has occurred. In extreme cases the
mineral buildup will permanently reduce the ow rate of
the lter. These cases can only be xed by replacing the
lter.
3. Biologic fouling is another potential cause of reduced
pure water production from the RO lter. Algae, bacteria
and fungi can land and grow on the surface of the RO
membranes. These organisms eventually block o
pores in the membrane leading to reduced production
levels. Letting lters sit for long periods of time without
running any water through them increases the chances
of biological fouling. After long term storage, running a
series of long ushes will often return the RO membrane
to normal production levels. Fully open the bypass hose
and then shut o your system’s pure water outlet. Run
it like this for 10 minutes and then open your pure water
outlet and restrict your bypass to its normal running
setting. Test the water coming out of the RO (not the
bypass water). If levels are as expected, use the system
like normal. Doing this ushing process 2 or 3 times may
be required to return to normal production levels.
4. Expect decreased production rates when running your
RO with colder source water. The ideal temperature for
source water is 77°F. You can expect around half the ow
for water at 50 degrees that you would get at 75 degrees,
even if both sources are at the same PSI. Use your TDS
meter to measure the temperature of your source water
to determine if this is the cause of lowered ow rates.
5. Leaks in the system and the pole tubing can release
pressure and take ow away from the jets in your brush.
A couple of small leaks in the pure water lines can cut
pressure to the jets in half. Read the “leaks” section
below for more information on eliminating leaks in the
system.

6 - The Solo Pure Water System Operation and Maintenance Manual
1. Strong bypass ow is normal during system operation.
This water is the bypass water and it contains a very high
TDS. This water is non-potable but is also not harmful to
plants. Do not drink bypass water.
3. Milky white bypass ow is a common occurrence when
starting up the system or using a new RO membrane. It is
trapped air being pushed out of the lter housing and will
stop once the air is gone.
Water Coming Out Of Bypass Hose
1. With the source water o, check that the tting is
properly tightened. Tighten until you feel the gasket
engage. All ttings are leak free hand tightened.
Do not overtighten.
2. Unscrew the leaky connection. Check the gasket in the
female tting for damage or deformation. Replace
gasket if necessary. Replace gasket before tightening
tting. Wrench can cause damage if over tightened.
3. Check brass ttings for damage or deformation. If
necessary replace brass ttings. Replacement parts
can be ordered from ABC or bought from a local store.
The plastic hole size is ½” national pipe thread (NPT)
and the Brass tting connection is a standard ¾”
Garden hose thread (GHT). Fittings should be attached
with an adhesive to prevent leaks. We recommend
Liquid Nails Perfect Glue from Home Depot.
Leak Between Brass Garden Hose Fittings
1. Unscrew leaky brass tting.
2. Check brass ttings for damage or deformation.
If necessary replace brass ttings. Replacement parts
can be ordered from abc or bought from a local store.
The plastic hole size is ½” national pipe thread (NPT)
and the Brass tting connection are a standard

13. Leaks
1. Retest your water sample. When you get a higher than
expected reading on your handheld TDS meter, it is a
good idea to use the water you are testing to wash out
both the measuring lid and the measuring prongs of the
meter itself. Do not get the body of the meter wet, it is
not waterproof. Minerals can stay in the cup from other
measurements and can make the sample appear to
have a higher TDS than it actually does. Taking multiple
samples ensures maximum accuracy.
2. Elevated TDS levels coming from the RO membrane
can indicate that the RO needs to be replaced. Use your
handheld TDS meter to measure the TDS water coming
out of the RO and compare that to the TDS levels of the
source water. Your RO should have a rejection rate of
over 80%. If the rejection rates are below normal, follow
the step below to ensure that the RO lter needs to be
replaced.
3. Running the Solo system on High TDS source water
will result in higher levels of TDS in the pure water. Adding
a DI lter after the system should remove the rest of the
dissolved solids.
4. If your RO rejection is lower than expected, you can
try running a 10 minute ush. Increasing ow through the
lter housing will help the ushing process. Fully open the
bypass hose and then shut o your system’s pure water
outlet. Run it like this for 10 minutes and then open your
pure water outlet and restrict your bypass to its normal
running setting. Test water coming out of the RO (not the
bypass water) to get the before reading. Check your RO
TDS to see if it is dropping to more acceptable levels.
Repeat the forward ush 2-3 times if necessary to drop
the RO TDS.
5. If your rejection is lower than expected, you can try
running a 10 minute ush. Increasing ow through the
lter housing will help the ushing process. Fully open the
bypass hose and then shut o your system’s pure water
outlet with the provided quick connect valve. Run it like
this for 10 minutes and then open your pure water outlet
and restrict your bypass to its normal running setting.
Check your RO TDS to see if it is dropping to more
acceptable levels. Repeat the forward ush 2-3 times if
necessary to drop the RO TDS.
6. If your TDS does not drop, your system is probably
exhausted. You can continue to use the exhausted
system, as long as the water exiting the system is still
pure enough for your cleaning application. Adding a DI
lter after the system can allow an exhausted system to
still be used longer.
