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 sucient using a pressure
gauge (P/N TA-PG). Trying a dierent source may lead to
better performance. Also check all hoses (incoming and
outowing) for kinks or blockages, especially hose reels
that are wound too tight. Trying a larger diameter hose
(½” or more) or a shorter hose length between the system
and the tap can also improve ow. Adding a pump, such
as the abc boost pump, 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. 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
Do not allow the lters or system to freeze. Failure to
do so could result in damage to your lters and Phaser
system. 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. RO and DI lters need to stay moist
but do not need to be full of water. 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. Do not allow DI
or RO lters to dry out. Dry DI resin will lose its charge

1. Remove Carbon/Sediment and DI Filters.
2. Using a 7/16” wrench, remove the clamps from the
RO Membrane lter (P/N WF2CRO-40) that doubles
as the stabilization base for the unit. Retain for
future use.
3. Remove fabric handle and install onto new RO
membrane.
4. Remove bypass hose.
5. Attach handle and clamps to new RO lter.
6. Attach bypass hose to new RO Filter.
7. Attach Carbon/Sediment and DI Filters.
Do not overtighten.
RO Filter 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. RO and DI lters need to stay moist but do
not need to be full of water.
Store lters indoors over the winter. Do not allow the
lters or system to freeze. Failure to do so could result
in damage to your lters and Phaser system. 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.
