SG2 Pure Water System Operation and Maintenance Manual - 1
Overview
Thank you for purchasing the Time Saver Series SG2
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. Bringing the latest technology & advancements
to the pure water window cleaning industry, abc &
Waterfed.com have produced the nest pure water
window cleaning system available today. Only the
highest quality parts & materials have been used to
assure you years of system longevity.
The following is provided to help you understand how
your system puries water. The SG2 is an AC powered
multi-stage water purication unit using sediment,
carbon, reverse osmosis, and de-ionization to remove
impurities from water before delivery to surfaces for
cleaning. Most water sources will have some amount
of minerals and chemicals dissolved in the water.
General life span of the lters will vary depending on
feed water TDS (Total Dissolved Solids). Based on an
average TDS of 100 ppm (parts per million) in your water,
approximately 10,000 gallons of water can be passed
through the sediment/carbon and DI lters before
replacement lters are needed. It is recommended
that the sediment/carbon and DI lters be replaced at
the same time. The RO membrane is rated to process

2. Initial Setup
3. Filter Replacement
1. (optional) Attach a hose (not included) to bypass outlet
to control where bypass water will ow.
2. Use the 24” connection hose to connect your Carbon
Sediment lter to the Pump. Attach the female end of
the 24” connection hose to the top of the carbon.
Attach the male end of the 24” connection hose to
the water inow of the pump. Screw on tight enough to
engage the rubber gasket. Do not over tighten, or you
could damage your brass ttings. Normally you want to
tighten the tting to the point where the female side will
no longer swivel.
3. Use the 16” connection hose to connect your pump
to the RO. Attach the female end of the 16” connection
hose to the water outow of the pump. Attach the male
end of the 16” connection hose to the top of the
RO lter housing. Screw on tight enough to engage
the rubber gasket. Do not over tighten, or you could
damage your brass ttings. Normally you want to
tighten the tting to the point where the female side
will not longer swivel.
4. Fully open the bypass valve on the bottom of the RO
lter housing.
5. Attach feed hose to carbon inlet on system and to
source water.
6. Thread inline pressure gauge onto the top of the DI
lter.
7. Thread plastic shut o valve onto the pressure gauge
and connect pole tubing. The push in connector on
the pole tubing goes in easier with the valve rotated to
the o position. Ensure valve is in open position before
proceeding to next step.
8. Turn on source water.
9. Wait for water to begin owing out of the bypass
valve/line.
10. Close bypass valve partially until desired bypass
ow is achieved. Do not close the bypass fully during
operation (some bypass water should always be
owing out).
Unscrew brass tting on top of the Sediment/Carbon
lter (P/N WF2CSC-21). Unscrew the wingnut at the
top of the carbon lter cartridge. Remove the carbon
lter by rst pulling top of the lter away from the frame
removing it from top bolt. Next, lift up to remove the
lter from the clip at the bottom. Discard used lter.
Slide the female end of the new lter into the clip at
the bottom of the frame so that the female inlet tting
is pointed forward. Swing the top so that the bolt is
inserted in the hole on the cap of the lter labeled SG
1&2. Tighten the wingnut on the bolt to secure the lter
(checking to make sure that the lter is seated in the
bottom clip. Attach your 24” connection hose to the
new carbon/sediment lter. Fittings should be tight
enough to avoid leaks, but over tightening could result
in damage to the brass ttings.
Unscrew brass tting from the bottom of the
Deionization (DI) lter (P/N WF2CDI-21) and any hoses
attached to the top of the lter cartridge. Unscrew the
wingnut at the top of the DI lter cartridge. Remove
the DI lter by rst pulling the top of the lter away
from the frame pulling it o of the bolt at the top. Next,
lift up to remove the lter from the clip at the bottom.
Discard used lter Slide the bottom of the new lter
into the clip at the bottom of the frame and swing the
top so that the bolt is inserted in the hole on the top
cap of the lter. Tighten the wingnut on the bolt to
secure the lter, checking to make sure that the lter is
seated in the bottom clip. Attach your brass tting to
the bottom DI lter. Fittings should be tight enough to
avoid leaks, but over tightening could result in damage
to the brass ttings.

4. Hooking Up To Water Source
Your SG2 is designed to be operated while standing up.
Locate an external water source. Attach one end of the
feed hose (not supplied) to the water source. ¾” garden
hose is preferred. Open the faucet at the building
and make sure all air is out of your source hose. Turn
o water and attach to the female connection on the
Carbon/Sediment lter. Turn water back on fully and
adjust bypass valve to desired ow rate.
Ensure the system is unpressurized by fully opening
the bypass valve and the RO only valve. Failure to do
so could result in injury as the pressure is released or
create a vacuum that will hold the old RO membrane
in place. Remove the yellow wedge piece from the top
of the RO housing with a phillip’s screwdriver, then
remove the white retaining ring by pulling it out of the
groove around the inside of the housing. Remove the
black cap from the top of the lter housing using the
“T” wrench. Insert the wrench into the threads on the
top of the housing and lift up to remove the cap. There
is an o-ring underneath the black cap, remove and
inspect this for any cracks or signs of wear. Replace if
necessary (part number FW7000-COR). Using a pair
of needle nosed pliers, remove the old RO membrane
from the housing by lifting it up. Apply a small amount
of Molykote 111, or similar silicone grease, to the top
and bottom protrusions on the new RO membrane.
Also apply Molykote 111 to the white rubber sealing
ring on the new membrane - this white ring will be on
the upper end of the lter when it is properly installed
in the housing. Insert the new RO membrane into the
housing by pushing it down and into the o-rings on the
bottom of the assembly. Coat the o-ring with molykote
and insert into shelf on the top of the RO housing.
Insert the black cap on the top of the housing by
pushing it down below the retaining groove. Insert the
white retaining ring in the retaining groove. Ensure the
white retaining ring is properly seated and reinstall
the yellow retaining wedge. Both of these keep your
pressure vessel top from shooting o.
RO Filter 5. Bypass Valve Operation
The system comes with a Bypass/Pressure Regulator
valve. The bypass valve is the primary way you can
control the pressure of your system. It also controls
the amount of water that your RO membranes lose
as bypass discharge during normal operation. There
should always be water owing out of the bypass
valve. Opening the bypass valve more will reduce the
amount of pressure that is used to produce pure water,
resulting in lower ow rates at the brush. Closing the
bypass valve will increase the amount of pressure
which can lead to higher ow rates at the brush, but
can diminish the life of the lter. RO membrane lters
use the bypass ow to remove concentrated dissolved
solids from the lter. Operating the system with the
bypass open (until the bypass ow is approximately
the same as the pure water ow) is one of the best
ways to ensure maximum life from the RO membrane
lters. Closing your valve so that the ow of the bypass
is roughly equal to the ow of pure water is a good
place to start. This will restrict ow for elevated system
pressure, but also allows some brine to exit your
membranes. It is recommended that you run your
system with the bypass valve fully open for a few
minutes each time you nish using your system to
help clean out your RO membranes and help extend
their life.

8. Operating Without Power
If your tap pressure is sucient to run the system
or electricity is not available, you can run your SG2
without power. A minimum tap pressure of 50 psi
is needed to push the water through the system,
but 80 is preferred. Water should ow freely through
the pump, but the position of the vanes in the pump
could block the free ow of water while not running.
After checking to ensure that water is reaching the
pump, quickly turning the pump on and o will move
the vane and allow water to ow freely through the
pump again.
Alternately you can bypass the pump by
disconnecting the 16” connection hose from the
top of the RO and the 24” connection hose from the
pump. Use the 24” connection hose to connect the
top of the RO housing with the top of the Carbon
Sediment lter. This eectively plumbs your SG2 like
an SG1.
7. Pump Operation
Your SG2 system comes with a direct drive rotary vane
pump. This pump has graphite vanes which push the
water through your system. Do not run the pump dry.
Running the pump without water could result in damage
to these vanes and a loss of pump function.
When running the pump, abc recommends that you
don’t shut o the valve on the pole tubing quick
connect or the outow of water anywhere on the
pole. This also includes restricting ow of the outgoing
pure water. A restriction or shuto can allow more of
the pressure before the RO housing to travel through
the membrane and into the DI lter. The RO housing is
able to handle more pressure than the DI lter and the
resulting pressure transfer can damage the DI lter. If
you wish to shut o the ow of water out of your pole
while the motor is running, make certain to set your
bypass valve so that the max system pressure doesn’t
exceed 120 psi.
6. Inline Pressure Gauge
The SG2 comes with an inline pressure gauge. You can
move the inline to any of the garden hose connections
on the system to take readings. We recommend you
attach the pressure gauge to the inlet of the DI lter
cartridge. This pressure should be between 90 and 110
psi while the motor is running. Do not run system with
the DI lter pressure above 120 PSI.
Your tap pressure can be measured anywhere in
the system. Do not attempt to measure the tap
pressure with the motor running. With the source
water owing, close the bypass valve and the shuto
valve on the pole tubing quick connect. The resulting
pressure is your tap pressure.
abc recommends that for normal use, you should leave
the gauge attached to the system outlet on top of the
DI as instructed by the Initial Setup. This will allow you
to monitor the pressure of your DI lter and ensure that
it doesn’t go above 120 psi. We do not recommend
using the shuto valve with the pump running as
this can cause the pressure to build up in the DI lter
cartridge. Check the pressure throughout the day to
ensure that it does not exceed 120 psi. To reduce
pressure on the DI, remove restrictions downstream
(kinked pole tubing for example) and open the bypass
valve.

SG2 Pure Water System Operation and Maintenance Manual - 5
10. RO Only Valve Operation
There is a 2 way wye located on the bottom of your RO
housing. This can be used in several ways.
First, it allows you access to the clean water coming
out of the RO membrane before it is run through the DI
lter. You should periodically test the TDS of this RO
water to assess the health of your RO membrane.
Depending on the TDS of your source water, your RO
membrane may purify the water suciently for your
cleaning application (abc recommends that TDS be
at least 10 ppm or below for most window cleaning
applications). If you, as the window cleaner, decide the
RO only water is clean enough for your application,
you can attach your pole tubing directly to the RO only
valve and shut o the ow of water to the DI lter to
preserve the life of your DI resin.
When using a RO membrane, there is a spike of higher
TDS water that passes through the membrane each
time you start using it. Users that wish to avoid passing
this higher TDS water through their DI resin can shut o
the DI side of the wye. Open the RO only side, turn on
the source water, run it for about 10-30 seconds, open
the DI side again and then shut o the RO only side.
Do not shut o both sides of the RO only wye if you are
running a pump, as that could damage the system.
9. Producing Pure Water
Connect your WaterFed® pole to the end of the
production water hose. 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.
11. TDS (Total Dissolved Solids) Meter
Total Dissolved Solids are the particles dissolved within
water that can lead to spotting on glass as the water
evaporates. Your TDS meter measured the amount of
dissolved solids by measuring the conductivity of the
water.
Push the “On” button on the TDS meter (included) –
capture a small amount of your production water in
the cap of the TDS meter to get a reading of the water.
A TDS reading of 0 – 10 is acceptable for cleaning
windows, specic 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’s TDS
reading to be higher than it actually is. Read all sections
before continuing for optimal system performance.
Your TDS meter also has a thermometer which reads
temperature. This can allow you to monitor the
temperature of your feed water. RO membranes require
more pressure to create the same amount of clean water
as the temperature of the water gets colder. Running
your system at feed water temperatures of less than 10
degrees celsius (50 degrees fahrenheit) could result in
low ow exiting the system.

13. Soap Residue
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 will be seen on the glass after drying. Most
often this is soap and or detergent residue actually left
behind by previous cleanings and brought out of the
pores of the glass and out from under the side gaskets
and seals of the glass on commercial installations
by the pure water cleaning process. This condition is
generally rectied by repeating the pure water cleaning
process until it is eliminated.
14. Shutdown
1. Turn o pump, disconnect from power supply.
2. Shut o ow to the pole tubing, then fully open
the bypass valve and let the system ush source
water through the carbon and the RO lter housing
for 3-5 minutes.
3. Turn supply water o. Disconnect source water hose.
4. Optional – Open RO only valve to drain water from
housings for transport.
15. Maintenance
Your SG2 system requires little maintenance to
operate at peak performance. As stated above, a
forward ush of your system after each use will help
the ROs remain free of contaminants.
Periodically check the TDS of the puried water with
the provided hand held meter. When the TDS levels
reach unacceptable levels for your application (ABC
suggests 10ppm or less for window cleaning and
40ppm or less for cleaning opaque surfaces) you
should replace both your carbon/sediment lter and
your DI lter together.
abc also recommends that you lubricate your wheels
several times a year (or as necessary) to ensure
proper mobility for your system.
Periodically check the electrical wiring and system for
damage. Test your GFCI by pushing the white button
to test the shut o and the red button to reset the
system.
12. Using A WaterFed Pole
®
Once your SG2 system is hooked up, and you have a
WaterFed® pole connected to the hose, 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. Providing
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 where there are 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.

17. Troubleshooting16. Storage
1. Ensure feed water is open and has water to it.
2. Check all hoses for kinks or blockage.
3. Connect to alternate water source.
4. Replace Sediment Filter (P/N WF2CSC-21).
5. Replace DI Cartridge (P/N WF2CDI-21).
1. Damaged RO membrane – replace (P/N WF2440-RO).
1. This is normal during system operation. This water
is the discharge water and it contains a very high
TDS. This water is not potable but is not harmful
to plants or surrounding areas. DO NOT DRINK
DISCHARGE WATER.
1. Remove DI Cartridge & Re-test system –
replace if ow increases (P/N WF2CDI-21).
2. RO Membrane is plugged –
replace RO membrane (P/N WF2440-RO).
3. Feed water temperature too cold for system
to process.
4. Replace Sediment Filter (P/N WF2CSC-21).
1. Verify supply water has acceptable ow & pressure.
2. Replace Sediment Filter (P/N WF2CSC-21).
3. Replace DI Cartridge (P/N WF2CDI-21).
DO NOT ALLOW DI or RO lters to DRY OUT. Dry DI
resin will lose its charge and therefore become unable
to remove dissolved solids from the water. Dry RO
membranes will develop cracks which allow more
dissolved solids to pass through the membrane. This
will deplete the downstream DI lters at a faster rate.
abc recommends that you run water through your
carbon and RO membrane lters 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. Always run your source water
through the carbon lter before the RO membrane
when ushing the lter.
abc strongly recommends ushing out the RO
membrane lter once every 2-4 weeks to ensure
the maximum lifespan of the lters. When ushing
the RO membrane lter, the source water should be
passing through the Carbon/Sediment lter before
the RO membrane. This will prevent damage to the
membranes from Chlorine and Chloramine. Periodic
ushing 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 wrap lters tightly in plastic wrap or plastic bags
and then seal with tape. This will reduce the chance
that the lter dries out when in storage. Store lters
and any unit with a pump indoors over the winter. Do
not allow the lters or pump to freeze. Failure to
do so will destroy your lters and pump. After lters
have been stored this way, they will need to be ushed
thoroughly before use. Leaving lters wrapped for
extended periods of time can lead to biological fouling,
which is why we recommend periodic ushing over
wrapping them for storage.
