MAINTENANCE
1. Regularly check to ensure that the RO system is operating correctly, all connections are
tight and secure and there are no leaks in the installation.
2. To prolong the life expectancy of the RO membrane,
the RO membrane should be regularly flushed to clear
any residue that may have settled inside the membrane.
We advise that the membrane is flushed out at least
every 1-2 weeks and this is simply achieved by turning
the flow restrictor/manual flush valve (19) to the open
position (see photo 12) for approximately 15–20 minutes
which will allow a greater flow of water to pass through
the RO membrane and flush out any residue and
particles that may have settled.
3. Following a manual flush of the membrane, the flow restrictor/manual flush valve (19) must
be returned to the fully closed position (see photo 2). Please Note: Failure to do so
could result in operating problems and/or damage to the RO membrane.
Please Note: During a manual flush of the RO membrane there will be a higher
percentage of reject water created so ensure that this water can be suitably collected or
drained to waste without any problems.
Please Note: All pure water collected during a flush of the RO membrane should also be
disposed of and not used because the pure water may contain contaminants due to the
flushing process.
4. Periodically check and replace the 5 micron sediment pre-filter, the active carbon block
filter and the RO membrane, as they will gradually become blocked and the RO water
production capacity and performance will be reduced.
USEFUL TIP: The 5 micron sediment pre-filter is enclosed inside a transparent filter housing
which provides a good visual indicator of when the filter is dirty and needs to be changed,
so at this stage it is also advisable to check the active carbon filter.
5. The following provides a simple guideline to when the components should ideally be
replaced:-
5 micron sediment pre filter Every 6 months*
Active carbon block filter Every 6 months*
RO membrane Every 2-3 years*
Flow restrictor/manual flush valve Replace periodically according to functionality
*Please Note: The lifespan of the 5 micron sediment filter, the active carbon block filter and the
RO membrane is dependent on several variables such as the levels of contamination (Total
Dissolved Solids) in the mains water supply and how frequently the RO system is used. To ensure
optimum results the filter components must be regularly checked and replaced as required.
USEFUL TIP: The V
2
Pure RO System incorporates an integral pressure gauge which is fitted
in-line after the RO membrane. The pressure gauge provides a good visual indicator of
when the RO membrane needs to be flushed or replaced. It is good practice to note the
pressure reading on the pressure gauge when the RO system is first installed because as
the filters and/or RO membrane start to become blocked, the reading on the pressure
gauge will start to drop, indicating that the filters need replacing and/or the RO membrane
need to be flushed or replaced.
