1.2 Purpose of This Product

Reverse Osmosis is the most advanced technology of water
purification in use today. The technique uses a nanotechnology
enabled semipermeable membrane which can reduce or remove
most harmful impurities found in tap and well water including:
microorganisms, nitrates, heavy metals, insecticides and much more.
The table below lists the performance of specific contaminants. This
is only a partial list of the virtually hundreds of thousands of
contaminants that Reverse Osmosis can filter.

1.3 Filters

The most essential part of any Reverse Osmosis system is its filters.
It is a misconception that all filters remove materials from the
incoming water, some filters actually add materials into water to
improve the taste, increase the mineral content and for other health
benefits. Although a Reverse Osmosis system can consist of many
filters, they all fall into one of three categories:

• Pre-Filters

• Reverse Osmosis Membrane Filter (RO membrane)

• Post-Filters

This Osmio D7 System will consist of five filters, which we will detail

below.

1.4 Pre-Filtration

The main purpose of pre-filters is to protect the more expensive
RO membrane from specific contaminants. Traditional RO systems
have pre-filters which only target sediment down to 5 microns and
chlorine as they can damage the RO filter and cause it to fail early.
The Osmio D7 Direct Flow system has the following 3 pre-filters:

• 5 Micron Sediment Filter

• GranularActivated Carbon (GAC)

• 1 Micron Sediment Filter

The Osmio D7 Direct Flow System uses High performance
pre-filters which are not only capable of removing Chlorine and
Sediments, but also reduce heavy meatals as well as other impurities
before the water goes into the RO membrane. Heavy metals
detrimental to the membranes life-span and performance

1.5 Reverse Osmosis Membrane

At the heart of every Reverse Osmosis system is the membrane
filter. The membrane filter consists of microporous, semipermeable
membrane sheets. The average pore sizes on the RO membrane is in
the range of 0.0005 mm (0.5 nanometers). The sheets are glued to
each other around three edges with a thin spacer in between
(this prevents the sheets from sticking to each other) to form a “leaf”.
Next, depending on the desired capacity of the membrane filter,
multiple leafs with mesh spacers in between (to allow the water to
pass between leafs) are stacked on top of each other. The stack is
then spirally wound with the open end of the leafs adhered to a
perforated tube that runs up and down the center.

The membrane filter has one water inlet and two exits. The feed
water first travels through the pre-filters and then to the membrane
filter. At the exit of the membrane filter one of the ports is the waste
water which is connected to the drain, while the other port is the
purified water which is plumbed to the post-filters. The figures on the
next two pages will help to better understand the RO membrane filter.

1.6 Post-Filtration

Contrary to including the word “filters” in their name, the post-filters
do not actually remove or “filter” anything from the water
(exception of coconut shell carbon based final polishing filters). Their
purpose is actually the opposite, to add health and aesthetic benefits
to the purified water. More specifically for tank-based systems, a final
polishing step is needed in order to remove any remaining odours or
flavours that may come from the system hoses or the holding tank.
Also, for residential systems additional minerals can be added to the
purified water to increase it’s health benefits.

4. Installation and Start-up

4.1 How to Use Quick Connect Fittings

Quick connect fittings (push fittings) are used in a wide variety of
plumbing, heating, electrical and fire suppression systems. Quick
connect works by inserting the tubing into a connection mechanism
that deploys fastening teeth onto the tubing surface. When opposing
force is applied to the union, the teeth are forced deeper into the
tubing, preventing separation of the union. The advantages of using
quick connect fittings are:

• They offer a significant time saving benefit over traditional connectors

• They tend to have less user failures compared to traditional connectors

• They require little skill or strength for their usage

• They do not require any tools to use and maintain them

Exploded Diagram of a Quick Connect Fitting

Osmio D7 Direct

All

systems take advantage of quick connect
fittings. To make a connection, the tubing is simply pushed into the
fitting. The unique locking system holds the tubing firmly in place
without deforming it or restricting flow. Use the steps in the figure on
the next page in reference to quick connect tubing connections for

this system.

Step 1: It is essential that the outside diameter of the tubing being
inserted into the fitting is completely free of scratch marks, dirt and
any other material. Inspect the outside of the tubing carefully.

Step 2: It is also very important that the sliced edge of the tubing is
cut cleanly. If the tubing needs to be cut, use a sharp knife or scissors.
Make sure to remove all burrs or sharp edges before inserting the
tubing into the fitting.

Step 3: The fitting grips the tubing before it seals. Lightly push the
tubing into the fitting until the grip is felt.

Step 4: Now push the tubing into the fitting harder until the tube
stop is felt. The collet has stainless steel teeth which hold the tubing
in position while the O-ring provides a permanent leak proof seal.

Step 5: Pull on the tubing away from the fitting and make sure it is
stays firmly in place. It is good practice to test the connection with
pressurized water before finishing installation.

Step 6: To disconnect the tubing from the fitting, ensure that the
system is depressurized first. Push in the collet squarely against
the face of the fitting. With the collet held in this position, the tubing
can be removed by pulling. The fitting and tubing can be reused.

4.4 Feed Water Connection

The purpose of the feed water connection is to feed the system with
water which is to be purified by tapping the cold water supply which is

usually

located under the kitchen counter. Please see the figure below for

instructions on how to make the feed water connection.

Feed Water Connection Diagram

4.5 Drain Saddle Connection

The purpose of the drain saddle is to prevent the tubing connected
to drain from popping out of place and potentially leaking where the
system is installed. Please see the figure below for instructions on
how to make the drain saddle connection.

Step 1: Select a location for the drain hole based on the design of

1

the plumbing. The drain saddle should be installed above the u-bend
if possible, on a vertical tail piece. Locate the drain saddle away from
the garbage disposal to prevent potential contamination and system
fouling. Please see figure below for a more detailed explanation. Use
a 7 mm (1/4”) drill bit to drill a small hole in the drain pipe for the
drain to pass through. Clean the debris from the plumbing and hold
before continuing.

Step 2: Remove the backing from the foam gasket and stick that half

2

of the drain saddle on the drain pipe so that the holes line up (a small
drill bit or other long narrow object can be used to help align
correctly). Place the other half of the drain saddle on the opposite
side of the drain pipe. Clamp and loosely tighten the drain saddle
using the nuts and bolts included. Use a Phillips screwdriver to
tighten the drain saddle. Connect the tubing from the drain saddle
quick connection to the “Drain” connection on the system.

4.6 Faucet Connection

The purpose of the faucet connection is to have access to water
on-demand. A proper location needs to be selected on the sink.
Special attention needs to be given to the stem on the faucet which
will be under the counter, it will need to be accessed in order to
fix the tubing nut with a wrench. Once the faucet location is picked,
a pilot hole of 5 mm should be made, followed by a 12 mm hole.

Important: Choose the correct type of drill bit for counter type.
Hammer Drill Bit: Cement, Tile, Granite, Marble and Marmoreal.
HSS Drill Bit: Steel, Wood, Chrome, Metal and Aluminum.

3. Connect the tubing to the stem of the faucet

4.7 Pre-filter Installation

The pre-filters are packaged in hygienically sealed bags. Do not break
the seal of the bags until right before their installation. Wash the
hands with soap before handling the pre-filters. Any bacteria that is
passed to the pre-filters can limit their lifetime and performance.

4.8 Membrane Installation

The RO membrane is packaged in a hygienically sealed bag. Do not
break the seal of the bag until right before its installation. Wash the
hands with soap before handling the filter. Any bacteria that is
passed to the RO membrane can limit its lifetime and performance.

1. When changing any filter, open the systems cover to reveal the
filters.

2. Open the sealed filters in order of the filter replaced and push and twist
into place as according to the corrosponding labels on the system

3. Use the filter housing wrench to tighten up the filters.

4. Recover the system with the cover previously removed

5. When installing a brand new set of filters make sure to run
the faucet for 5-10 minutes to clear the carbon fines
(allow for 3-4 days if any milky look to the water as this is trapped air)

4.11 Verifying the Installation

To begin please plug the power cord of the Osmio D7 into a
well maintained electrical socket. bringing the faucet handle down so
that it is perpendicular to the faucet stem.

Now slowly open the feed water valve in order to prevent the
hammer effect. At first open it only 10%. After one minute, open the
feed water valve to the half way level. Finally after another minute
fully open the feed water valve. The system will take on water and
slowly push all of the air trapped inside out through the faucet. Once the
feed water is opened 10% of the way, the pump should automatically
begin to vibrate.

Once the water has reached the faucet, at first blackish color water
will flow. This is normal and is caused by the dust that accumulates
from the coconut shell carbon granules banging against each other
during shipment. Only about half of a liter of blackish water should
come out, afterwards followed by clear water.

Next, let the water run like this for 5 minutes and then turn off the
faucet. Let the system pressurize for another five minutes and now
check the system for leaks. Make sure to carefully look at all of the
tubing and fitting connections for any drops. If any leaks are found,
the system should be depressurized and the tubing should be
removed and inserted back into the fitting.

Allow the system to clear out by running the tap for for 5-10 minutes,
At first “cloudy” water can be seen on the purified end. This is normal
and safe. The system is just pushing out all of the air that is trapped
inside (this can last for up to 3-4 days).

5.1 Recommended Filter Change Durations

Filters can run at higher filtration efficiencies with a longer filter
lifetime. There is also a significant amount of added value and
technology that can be incorporated into the filters.

Osmio D7 System takes advantage of water filtration technology to
produce the highest quality water at the lowest cost of ownership.

When compared to other systems in the market. However, it should
be well noted that there are currently no water filtration systems in
the world that are designed to be run until all of the filters clog. In
fact some filters fail by opening of the pores as opposed to clogging.

It can generally be stated that the filter lifetime starts once the filters
touch water. Even if the user goes on prolonged periods of not using
the system (such as vacation) or the water consumption is low, the
filter lifetime does not stop or slow down. This is true because the
filters are made from organic compounds such as paper, coconut
shell, minerals, etc. and they will degrade in water over time.

Additionally, changing of the filters is a “Preventive Maintenance” as
opposed to a “Corrective Maintenance”. This means that filters are
changed in order to prevent future failures whereas corrective
measures are done after a failure has taken place.

The filters for the Osmio D7 Direct Flow system have individual lifespans
which you can see on the table below

)

5.2 Changing the Filters

In order to have a successful filter change for this
Reverse Osmosis System, please follow the steps on the next page
carefully

Filter Change Procedure

1. For pump based systems unplug the electrical cord from the socket.

2. Close the feed water valve so no water can come to the system.

3. Open the faucet and let the system depressurize.

4. Open the system side panel to access the filters and their slots

5. Remove the used filters and throw them away. Be careful to
wash the hands after touching the filters.

6. Proceed to replace the filters with the new set, unpackaging them
one by one and replacing as you go.

7. Push and twist the filters into place and they will not rise back up
and stay in place

8. Use the filter housing wrench to tighten the filters in place if needed

9. Put side panel back on covering the filters

10. Plug the system back into the socket.

11. Open the feed water valve to allow water to the system.

12. Open the faucet, whilst checking for any leaks, ensuring all is well.

13. Run the tap for 3-5 minutes to attempt to clear air and carbon fines
from the water.

5.3 Going on Holiday

The
prolonged periods of time (+2 weeks) when it will not be used. It is
important to note that once the filters touch water the life span of the filter

starts.

This is true because the filters are made from organic compounds such as

paper, coconut shell, minerals, etc. and they will degrade in water

over time.

However, if the system will not be used for prolonged periods of time
there are certain things that can be done in order to prevent
problems arising from not being used for prolonged periods of time.
Please follow the steps below if the user plans to not use the system,
for prolonged periods of time.

1. Unplug the eletrical cord from the socket.

2. Close the feed water valve so no water can come to the system.

3. Open the faucet and let the system depressurize. Wait until the
water running from the faucet is gone.

of not using the system.

5. Upon return, plug the electrical cord back into the socket.

6. Slowly open the feed water valve to only 10%. After one minute,

open it to the half way level. After another minute fully open
the feed water valve.

7. As the faucet remained open from before leaving on holiday,
confirm that water is flowing through the faucet. Run water for
15 - 20 minutes this way.

8. The system will be ready to use after emptying the
water for 3-5 minutes.
