Regulatory information
1The flow rate is tested at 25 °C; lower water temperatures will reduce the flow rate.
2The device is influenced by feedwater conditions such as pressure, temperature, TDS levels, and hardness.
The better these incoming conditions, the better performance. Depending on local water quality and use
environment, the lifetime of the filters, flow rate, recovery rate and salt rejection will vary.
3The device complies with European legislation regarding health, safety, and environmental protection, and
can be sold in Europe.

claims are void unless the provisions in this
manual are observed and followed.
Proper use
The device is suitable for filtration of drinking
water quality at up to max. 25 °C and an inlet
pressure of max. 6 bar.
Observe: The feedwater must not
exceed the limit values given in the
technical data sheet – page 5.
The device shall only be used for its intended
purpose as designed and as described here
in this manual. Any other use is considered
“improper”.
Warning! The device must be fed
only with cold drinking water.
Permissible operation method
Observe: To protect the drinking
water, observe the country-specific
guidelines for drinking water
installations in any work on the
device.
-The device must be disconnected prior
to performing any maintenance work on
the drinking water supply. Rinse the water
pipe sufficiently before reconnecting the
device.
Observe: Improper installation of the
device may cause damage to it.
-Observe any country-specific installation
regulations (such as DIN 1988, EN 1717),
general hygienic conditions and technical
data for protecting the drinking water.
-Unauthorized modifications to the device
and technical alterations are not permitted.
-Avoid mechanical damage to the device.
Otherwise, the warranty is void.
-Install a stop valve upstream of the device.

How to install
Before you start, please be sure to clean your
hands thoroughly as well as any tools used
during the installation of your purifier.
The installation will take approximately 1 hour.
Before installation, ensure that the cold water
valve is turned off/closed.
TURN
OFF
Note that the length of the 1/4″PE pipe is
3 meters. This length is to be used for
multiple connections so use only what you
need for each connection and save the
remaining for later installation steps.
When you cut the PE pipes be aware that the
pipe is not compressed when you insert it into
connections.
Before installation, remove the grey IN and
OUT plugs as well as the DRAIN plug. Keep
the plugs as they will be reused if the device
is relocated.
How to remove the plugs
1. Use a flat device, e.g. a screwdriver to push
down the white release collar.
2. You can now pull the plug upwards with
your fingers.
Note that there might be a release of air when
removing the plugs.

Complete the
installation
The filter life indicator on the top panel will
flash and you will hear a sound. Now you can
hear water flowing into the A2O Pure.
Once the lights stop flashing, open your
faucet and check for leakages.
After installing your A2O Pure or replacing
filters, the device must be flushed before
consuming the water. Note that the first water
coming out will be black since some of the
activated carbon is washed out. The device
is flushed by leaving the faucet open for
15 minutes.
Now you are ready to drink naturally purified
water.
Enjoy.
