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
All Osmio D7 Direct 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.

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.
1Step 1: Select a location for the drain hole based on the design of
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.
2Step 2: Remove the backing from the foam gasket and stick that half
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.
HSSDrill Bit: Steel, Wood, Chrome, Metal and Aluminum.
1. Place the faucet stem through the 12 mm hole and mount it per
the pictures above.
2. Connect the remaining faucet installation parts to the tubing per
the diagram above

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)
