1. Introduction
1.1 Purpose of This Manual
The purpose of the Installation, Operation & Maintenance Manual is
to give users a reference for Technical Specifications, Connection
Diagrams, Installation Procedures, System Operation and System
Maintenance of their Osmio D7 Direct Flow Reverse Osmosis System.
The essential information contained in this manual will allow the
user to make full use of the system. For special situations, it is
recommended that the user contact their authorized dealer or
Osmio Water Technology (www.osmiowater.co.uk).
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.

2. Specifications
2.1 Technical Requirements
The technical requirements for this system can be found in the table
below.
2.2 Supply Water Requirements
The supply water requirements for this system can be found on page
9. If the water supply does not meet these requirements, the filter
lifetime and output water quality of the system can be affected.
Please see the table on the next page for the recommend filter
lifetime of this system. This duration will be reduced depending on
how much the water quality exceeds the limits.
Electricity 220 VAC/50 Hz*
Feed Water Pressure 1Bar Min. -4Bar Max.**
Feed Water Temperature 5-38
o
C
Feed Water Connection 1/2" NPT
System Weight (no water) 14 KG
If the feed water is supplied with raw well water, laboratory test of
the water should be done before installing the system. If there is a
significant exceeding of these limits, a well water treatment system
at the source should be considered to correct the water quality.
