5.2
Qualified personnel
Installation, operation and maintenance of the filter system is only to be carried out by trained
persons and skilled personnel.
Trained persons
Have been trained regarding the tasks assigned to them and the potential hazards
resulting from improper operation.
Skilled personnel
Are capable, by virtue of their technical training, knowledge and experience, as well as
their knowledge of the relevant provisions, to operate and maintain the filter system.
5.3
Procedure after breaks in operation
In the event of prolonged breaks in operation, close the check valve in the filter system intake.
After a break in operation exceeding two days (weekend, holiday, etc.), the filter system
must be flushed with 4–5 litres of water before being reused.
After a shutdown of 4 weeks or more, the filter cartridge must be replaced by a new one.
5.4
Replacement intervals
The filter cartridge must be replaced on reaching the capacity stated in Section 2.2. The filter
cartridge must be replaced on a regular basis and no later than 12 months after installation.
The filter must also be replaced after a shutdown period of 4 weeks or more.
5.5
Disposal
Dispose of exhausted filter cartridges, surplus parts and packaging in accordance with
the local regulations. If local collection points are available, take all product components
for recycling. This will help protect the environment.
6 Installing the filter
6.1
Water quality
The filter system may only be supplied with cold water that meets the legal requirements
for drinking water quality.
I
WARNING!
Hazard caused by improper use!
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.
6.2
Pressure
I
CAUTION!
The maximum nominal pressure must not exceed 8 bar. If it is higher, a pressure reducer
must be installed upstream of the filter system.
INFORMATION!
f DInstalling a pressure reducer can reduce the flow.
f For the filter system to function correctly, the intake pressure must not fall below 1.2 bar.
Pressure surges are to be avoided. If they do occur, the sum of pressure surge and idling
pressure must not exceed the nominal pressure of 8 bar. The positive pressure surge must
not exceed 2 bar and the negative pressure shock must not fall below 50% of the settling
flow pressure (see DIN 1988 Part 2.2.4).
