Introduction
Thank you for purchasing this quality product.
To minimize the risk of injury we urge that our clients
take some basic safety precautions when using this device. Please read the operation instruc-
tions carefully and make sure you have understood its content.
Keep these operation instructions safe.
General instructions
•
This manual describes the Usage of all our RO systems.
•
Note that some parts of this manual are intended for certain systems. Usually, the arrangement
of the filter stages is always the same. The number of filter stages depends on the model that
you have bought, between 1 and 6.
•
For RO-Systems without pump: If you use a pressure tank, the input water pressure should be
higher than 5.8 bar (85 psi).
Operation principle
The RO system adopts U. S. high-tech reverse osmosis technology. This automatic reverse osmosis
system is composed of five to seven filtration stages:
•
The
first stage:
The PPF cartridge removes suspended substance and other substances up to
5 µ in raw water.
•
The
second stage:
granular activated carbon cartridge.
•
The
third stage:
filter block of activated carbon.
•
The
fourth stage
is the actual reverse osmosis membrane. The pre-cleaned water passes
through the RO membrane, the pores of which are so small that organic contaminants (pesti-
cides, insecticides, medicine, hormones, etc.), bacteria, and viruses are retained. The water
flowing out of the membrane is stored in a pressure tank. When the gooseneck tap is opened,
the pure water passes through the
fifth stage,
the highly active activated carbon cartridge
“Gourmet,” which gives the water a pleasant taste.
•
If necessary, you can install a
sixth
and
seventh stage,
i.e., a mineral enrichment cartridge
“Santé,” which adds the desired minerals to the water. It is also possible to use a UV lamp that
kills bacteria and viruses.
•
The system controls the water purification process automatically. If the water pressure is too
low or the water tank is full, the system stops automatically. When the water pressure returns
to normal, the system switches on automatically.
The different filter stages
In order to maintain the pure-water quality, the filters must be replaced regularly depending on the quality
of the raw water. With a daily consumption of 10
ℓ pure water and the use of public tap water, the fol-
lowing idle times can be expected:
