4 Function of the filter

4.1

Use

Bestmax filter cartridges are used to decarbonise cold water so that it meets the legal requirements
for drinking water quality. They reduce the scale content and carbonate hardness of drinking wa-
ter, thus protecting catering equipment such as coffee machines, espresso machines, hot and cold
drink vending machines, steamers, combi steamers, ice cube machines from harmful limescale
deposits. What's more, the taste of food and the aroma of drinks are improved by removing
unpleasant odours and tastes, e.g. chlorine. Particles are also filtered out of the water.
4.2

Design

The natural water (A) flows to the filter cartridge (Fig. 2). In area (E), particles are removed by me-
ans of a pre-filter while unpleasant odours and tastes, e.g. chorine, are removed by active carbon.
The water is then decarbonised by ion exchangers (F), treated with active carbon (G) and then filte-
red (H).
Integrated into the filter system is the bypass setting mechanism, which prevents a specified
amount of the natural water from being decarbonised. This amount of water is only filtered by
active carbon (G) and the particle filters (H). In the outlet (D), the decarbonised water and the
bypass water merge again.
Depending on the hardness and usage of the natural water, setting a defined
amount of bypass water on the filter head supplies the connected appliance
with an optimal water quality.
A Natural water intake
B Bypass water flow

G Active carbon filtration; also filters the bypass water
H Particle filtration; also filters the bypass water

5 Operating and safety instructions

This section provides an overview of all the important operating and safety aspects to ensure safe,
trouble-free operation. Despite every safety precaution having been taken, every product harbours
residual risks, especially if handled incorrectly. The warranty will only be valid if the instructions in
these installation and operating instructions are observed and followed.
5.1

Proper use

The filter system is used solely to decarbonise (reduce the limescale content of) cold water of
drinking water quality and to remove unpleasant odours, tastes and particles that can be contained
in drinking water. The filter is designed and constructed exclusively for its proper use described wi-
thin these instructions. Any other use is deemed improper.

WARNING!
f The filter system may be only be supplied with cold water of drinking water quality.
Improper use, e.g. using the filter to treat water other than that of drinking quality, poses a health
hazard if you were to drink said water. This can be a microbiological hazard if the natural water is
contaminated by microbes. The hazard can also be caused by high concentrations of heavy
metals or organic impurities in the water.
