IMPORTANT
Please read this manual carefully and follow the instructions herein for the
guarantee that your reverse osmosis system works properly.
Non-compliance with these instructions will cause the warranty to be made
void.
The manufacturer cannot be held in any way liable for any damage to people
or property caused by a failure to comply with this attached manual, which
is an integral part of the scope of supply.
This manual is valid for the SO3100K versions.
The kit is intended for use in a household environment. In particular, its use
consists of processing and supplying already drinkable water for human
consumption. Any other use is not permitted.

1 - INTRODUCTION
Osmosis is a natural phenomenon for which a solution poor in mineral salts passes
through a semi-permeable membrane then it is diluted in another one that has a greater
saline concentration.
By applying counter pressure, this procedure is inverted and you obtain REVERSE OS-
MOSIS: in fact, by pushing a solution with a high concentration of mineral salts against
a special membrane, PROCESSED WATER is obtained. Due to its structure and prop-
erties, the membrane almost completely retains dissolved salts, heavy metals, pollutant
elements, bacteria and viruses letting the water pass in all its genuine purity.
REVERSE OSMOSIS is therefore the safest and most widespread purication system
around the world; the advantages, other than basic reliability of the system, is represent-
ed by the simplicity of assembly, the very low operating costs and the total absence of
chemical products.
The SO3100K model is capable of eliminating all impurities and harmful pollutants for
health from the water. Treated water is the ideal solution for household use and delivery
since the exclusive ltration system forms a safety barrier against different pollutants in
groundwater.

3 - SAFETY
The electrical safety of this equipment is only ensured when it is connected to an electrical
system with a sufficient ground socket and a differential switch pursuant to law.
Checking this fundamental requirement for safety is compulsory. If in doubt, require
assistance from a qualied technician.
Use of the SO3100K, as with any other equipment connected to an electrical system,
involves compliance with certain fundamental safety rules:
- do not touch the reverse osmosis purifying system with wet or damp hands or feet;
- do not detach or connect the plug in the socket with wet hands;
- do not pull the power supply cable to detach the plug from the socket;
- do not leave the reverse osmosis purifying system exposed to atmospheric agents;
- do not allow the reverse osmosis purifying system to be used by children without su-
pervision;
- before carrying out any cleaning or maintenance operation, disconnect the reverse
osmosis purifying system from the electrical mains by detaching the plug;
- in the event of a fault or poor operation, switch off the reverse osmosis purifying system
and do not tamper with it. Contact an authorised technician for any intervention; in the
event of replacement of parts of the reverse osmosis purifying system for maintenance
or due to a fault by an unauthorised technician, ensure said parts comply with legis-
lation in force.
The manufacturer cannot be held in any way liable for possible inaccuracies in this in-
struction manual due to printing or transcription errors.
The manufacturer also reserves the right to bring all changes to the reverse osmosis
purifying system, as deemed useful or necessary, without altering its basic characteristics.
4 - STORAGE
The packaged equipment must be stored in a dry place (without condensate), protected
against bad weather.The permitted temperature is 0-50°.You should consider that, even if
carefully packaged and protected, the system must be considered and handled as fragile
material. On receipt, the packaging must be opened to check the equipment is intact. If
damaged, immediately notify the carrier.

5 - USE CONDITIONS AND PERIOD OF USE
Reverse osmosis system, processing essentially consists of adjustable reduction in xed
residue in treated water.
The machine is intended for use in a closed and protected environment, not outdoors.
Its use consists of treating and supplying drinking water for human consumption and
for technical use. Any other use is not permitted.
Attention: this equipment requires regular, periodic maintenance to
guarantee the requirements of treated drinking water and to maintain the
improvements as declared by the manufacturer of the reverse osmosis
system for domestic use for the treatment of drinking water. Equipment for
the treatment of drinking water. Input water must be drinkable according to
Ministerial Decree no. 31 of 2 February 2001.

For the maintenance method, see the specic chapter.
To dene the period of use and the maintenance methods, specic tests were carried
out. Furthermore, a water sample was analysed to verify the altered parameters and
compliance with MD 31 on 2 February 2001.
Important: After installation, the machine must be powered for hygiene
reasons (ushing) and to have correct management of the exhausted lter.
Sanitise and replace the pre-lter after periods of disuse longer than 10 days
in the absence of electrical power supply.
The results of drinkability testing of the water taken before and after SO3100K are outlined
below. Both tests, carried out by an accredited institute, conrm the water to be drinkable.
In particular, it is conrmed that treatment efficiently combats various parameters, in
particular conductivity, hardness and various chemical substances.
