4.3 Qualified personnel
Only authorised, trained persons and professionals shall install, commission and maintain the
filter system.
Authorised, trained persons have obtained instructions regarding the assigned tasks and
possible risks in case of misuse or improper operation.
Professionals are in a position to install, commission and maintain the device, as a result
of their technical training, knowledge and experience, as well as knowledge of applicable
regulations.
4.4 Pressure
I
CAUTION!
f
If the maximum nominal pressure exceeds 8 bar (116 psi) a pressure reducer must be installed
upstream of the filter system.
NOTE!
f
Installing a pressure reducer can reduce the flow.
f
The inlet pressure of the filter system should be higher than 1.2 bar (17.4 psi).
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 (116 psi). The positive pressure surge
must not exceed 2 bar (29 psi) and the negative pressure shock must not fall below 50% of the
settling flow pressure (see DIN 1988 Part 2.2.4).
4.5 Operation after a break or shutdown / Replacement intervals
In the event of longer breaks in operation, close the shut-off valve in the inlet of the filter system.
After a break in operation exceeding two days (weekends, vacation, ...), rinse the filter system
with 4-5 litres (1.1-1.3 gallons) of water before reuse.
Replace the filter cartridge ...
on reaching the capacity stated in Section 3.2.
no later than 12 months after installation.
after a shutdown of 4 weeks or more.
4.6 Disposal
Dispose of exhausted filter cartridges, surplus parts and packaging according to local
regulations. If local collection points are available, recycle all product components to protect the
environment.
5 Installing the filter system
NOTE!
f
Decarbonized water contains free carbonic acid. Only appropiate materials are to be used
for installation. Original BWT accessoiries are recommended.
5.1 Unpacking the filter system
Remove the filter system from the packaging. Inspect the delivery for completeness and trans-
port damage. Defective parts must be replaced immediately.
I
CAUTION!
f
Faulty or defect parts must be replaced immediately.
f
Always ensure a safe and clean working environment.
