4 - Phaser Pure Water System Operation and Maintenance Manual
9. Maintenance
1. Close the shut off valve to the pole. Open bypass
valve to fully open position and flush out the system
for 3-5 minutes.
2. Turn supply water off.
3. Disconnect water line and tip system on end if
draining is desired.
8. Shutdown
7. 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.
The Carbon/Sediment Filter should be replaced every
6 months with frequent use and should not be kept
in service for more than a year. Failure to replace the
carbon filter regularly can lead to chlorine reaching
your RO filter and result in damage to the membrane.
We often recommend that users should replace both
their Carbon/Sediment and DI filters at the same time
as this usually ensures that the Carbon/sediment filter
is kept fresh without having to track service dates.
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 RO filter. For example, 100 TDS
source water with 10 TDS leaving the RO indicates
90% rejection. When RO rejection rates drop below
80% it is generally time to replace the RO filter
canister. As stated above, bleeding the RO at the
beginning of each use and flushing the RO at the end
of each use are essential to achieving maximum RO
lifespan. Trapped air can result in the plastic overheating
and pressure rating of the RO housing dropping. Setting
up your system out of direct sunlight on hot days will
also help protect the plastic RO housing from heat
damage.
The lifespan of your DI filter depends on the TDS of
the water entering the filter. Periodically check the
TDS of the purified water leaving the DI filter 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) the DI filter is completely
exhausted and should be replaced. See troubleshooting
section below for more information on high TDS levels
coming from the system.
10. Filter Replacement
1. Unscrew the Carbon/Sediment filter housing
(P/N WF2CSC-6) from the inlet side of the unit.
2. Screw the Carbon/Sediment filter housing back
onto the inlet of of the RO filter. Do not overtighten.

Carbon/Sediment Filter
1. Remove quick connect shut off valve.
2. Unscrew the DI filter housing (P/N WF2CDI-6)
from the outlet side of the unit.
3. Screw the DI filter housing back onto the outlet of
the RO filter. Do not overtighten.
4. Replace quick connect shut off valve.
DI Filter
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 flow 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 or
any filter freeze when operating in lower temperatures.
