What is Reverse Osmosis? At its most basic, it is a water separation
device. Water is passed under pressure over a semi-permeable membrane.
The holes in the membrane are large enough to allow water molecules
through but not large enough to allow other larger molecules
(dissolved solids) through. An RO-MAN system will remove 92 – 98% of
the “Total Dissolved Solids” (TDS) from the water. By adding a
De-ionisation stage we can remove 100% of the TDS from the water until the resin is
depleted.
How does the R.O. Filter work? I’m sure that most people remember
learning about osmosis in school. Just to refresh: It is the process
by which clean water is attracted to dirty water when separated by a
semi-permeable membrane. By applying pressure we can reverse the
process - Hence the name “Reverse Osmosis”.
What are the Stages in an R.O. System? The membrane is the heart of
the system & needs to be protected. This is done by pre-filtration.
Depending on the size of your system RO-MAN systems have two or three
pre filters. For this purpose we are looking at a 3 stage 50 gallon per
day system.
Stage 1: 5 Micron Sediment Filter – for the removal of sediments
such as dirt, sands and rust. We do not use a 1 micron filter as we
find that they block very easily and this affects the performance of
the system.
Stage 2: Carbon Block Filter – This is used for the removal of chlorine, some heavy
metals & other contaminants. RO-MAN use a top quality roasted coconut husk
activated carbon block filter.
Stage 3: The Membrane– As mentioned earlier this is the heart of
the system. An RO-MAN membrane removes 92-98% of the Total Dissolved
Solids in the water by the process described earlier. As it is the
heart of the system it is important to have the best possible
membrane. RO-MAN uses a “Thin Film Composite” membrane made under
licence for us in the USA by a leading membrane manufacturer..
After the water has passed through the membrane you have two
options. 1 – Use the water as it is.
2 – Further polish the water using De-ionization
.
De-ionization – RO-MAN membranes remove 92 – 98% of the TDS in the
water. For some applications, such as drinking water this is perfectly
adequate. For other applications such as Marine fish keeping and
window cleaning a TDS of zero is necessary. To attain a 0 TDS we use
a De-ionization (DI) Resin. This is a granular substance that acts
like a sponge and sucks the remaining TDS out of the water until it
reaches capacity. You should monitor the life of Resin with a TDS
meter.

Preparation
Determine the location for the installation of the system. Avoid locations where the
system might come in contact with hot water pipes, other hazards or is exposed to
extreme cold, an RO membrane will be damaged by frost.
Determine the location for the discharge of the waste water.
Determine the location of the cold water pipe. To assure you are using the cold water
line, turn on both the hot and cold tap. After the water is warm to the touch, feel the
pipes under the sink. It will be easy to identify the hot and cold pipes.
SHUT OFF THE WATER
Locate the water shut-off valve for the cold water feed line of your mains supply.
Accidentally hooking up the system to the hot supply line will permanently damage
the membrane (See Conditions for operation).
Close the cold water valve. Turn on the cold water tap only to assure that the line is
completely shut off and the line is drained… if no shut off valve is located under the
sink, turn off the main supply at the entry to the house.
Before starting to fit the saddle clamp to the cold water supply ensure that the valve
is fully open i.e. when looking down the wing nut is turned anti clockwise as far as it
will go (don’t force it).
Now fit the saddle valve to the 9 or 15mm copper cold water supply pipe ensuring
that the spacer is fitted appropriately, so that the spacer fits snugly to the pipe, then
tighten the lower bolt with a spanner.
You can now connect the red ¼” pipe, which will feed the RO system, by simply
pushing it into the saddle valve as far as it will go and then gently pulling back to
ensure that it is gripped securely.

NOT NOW but when you are ready to feed water to the RO system you turn the
wing nut fully clockwise which will cause a spike to be driven into the copper pipe
and then anti clockwise to start the flow of water.
Please note do not use this valve on a regular basis to turn the system on
and off, a ball valve should be used for this.
NOTE ON PUSH FIT CONNECTIONS:-
PIPE QC FITTING
COLLET
The Push Fit Connectors are opened by pushing down on the Collet ring with two
fingernails and pulling the hose at the same time. If your nails are not user friendly,
then use a pair of pliers, a small spanner or any tool that can apply pressure on both
sides of the Quick Connectors Collet.
The Red Pipe
After cutting the red pipe to an appropriate length connect it to the red capped inlet
of your Sediment Filter housing found at the top right of the RO unit and marked with
an up arrow and the word “IN”. Do NOT turn the water on yet!
The Green Pipe
One end of this to be attached to a suitable waste water discharge point, typically
this will be a 3 mm white plastic domestic pipe.
Should this be the case a mm hole drilled into the top of the pipe will accept the RO
system waste pipe, this can be sealed with silicone.
An alternative is to use the same pipe as the washing machine.
The other end should be run to the vicinity of the CCB filter housing but do not cut
this yet as it will eventually have to be connected to the membrane housing.
The Blue Pipe
RO This can be connected to the outlet of the DI Unit and the other end to your point
of use. Bear in mind that you will have to discard the first 2 gallons from this pipe.

The membrane has a plastic core in the centre of the membrane material. You will
see there are two small black o-rings. It is recommended that both the two small
black o-rings and the large black O ring are given a VERY light smear of petroleum
jelly such as Vaseline to aid insertion. Holding the housing unscrew the housing cap
complete with pressure gauge and insert the membrane with the two small, black o-
rings first, it will stop at the large black gasket seal located on the outer edge of the
membrane material. Push the membrane into the housing sometimes it’s a tight fit so
push with adequate force. You will feel it “seat” into the housing.
Once the membrane is seated properly, make sure the housing “o ring” is fitted and
moist. Then screw the housing cap onto the housing.
(YOU OULD DAMAGE THE MEMBRANE IF YOU DO NOT DO THIS)
Disconnect the pipe from the CCB filter housing (see page 3 or 4) and connect the
supplied green pipe to this connector. The other end to go to where the waste water
will be discharged
Switch the water supply back on by opening the saddle valve (see previous
Installing Supply Feed) by slowly turning the saddle valve wing nut counter clockwise
until fully open. Check seal for leakage, If necessary tighten the bottom nut lightly.
Now allow at least 2 UK Gallons of water to run through the system
Turn the water off.
