The Solo Pure Water System Operation and Maintenance Manual - 3
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 off 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 filters has left the bypass line, adjust
valve to desired flow rate. Open the shut-off valve
between the hose and the pole to allow water to flow
through the pole and wash glass. Do not drink pure
water made from your system. If using a pump, wait
for water to flow 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 filters use the bypass flow to remove
concentrated dissolved solids from the filter. There
should always be water flowing out of the bypass
hose. Inadequate bypass flow will result in fouling and
possibly damage the RO filter.
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 filter housing
through the bypass line.
The bypass valve on your Solo System is drilled out so
that enough bypass flow 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 flow should be
roughly equal to the flow of pure water leaving the
system.
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 you run your system with the
bypass valve fully open for 3-5 minutes each time
you finish 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
filter may be required, after the system, to polish off 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 specifically
to operate on municipal water sources. Sediment or
other special filters can be added before the system to
minimise the effects 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.
