Chapter 3 - Installation instructions / Operation

3.1 User information on the closing mechanism

The container is closed by means of a construction
consisting of a cover, the sealing o-ring and a bracket.
Before closing, ensure that the filter fabric is attached
to the ventilation valve.
To close the container, the o-ring must first be
attached to the cover. The cover is turned laterally into
the tank, brought into a horizontal position and then
pulled straight up so that the o-ring is pressed from
the inside against the curve in the wall of the opening
of the tank. The retaining bracket is then folded over
so that the o-ring is pressed on the inside of the tank.
Please note that the o-ring and the contact pressure
from the inside ensure the seal of the tank.
Filter fabric on the ventilation valve.
The cleanliness of the sealing surfaces is very
important for the tightness of the o-ring seal. In
particular when the tank is filled with filter media,
such as ion-exchange resins, the sealing surfaces
can become dirty. Clean the sealing surfaces and
the o-ring every time you reassemble the cover
construction.

3.2 User note - safety valve and flow limiter

Whenever the ion-exchange tank is connected to the
tab water supply, an approved backflow preventer
valve must be installed in the inlet of the water filter
system for compliance with the regulation DIN EN 1717,

3.3 User note - nylon fabric on the water inlet and water drain pipe

As soon as the tank is opened, a visual inspection of the nylon fabric should always be carried out. It
should be replaced if damaged. Otherwise the filter medium can be rinsed out of the filter tank.

3.4 Installation note - fine filter

When using the filter system with a liquid that is contaminated by undissolved substances, a fine filter
with a filter sharpness of at least 50 μm should be installed in the inlet of the filter system to prevent
contamination of the nylon fabric.
