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 pressu-
re 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 2.2.
no later than 6 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
5.1 Unpacking the filter system
Remove the filter system from the packaging. Inspect the delivery for completeness and
transport 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.
5.2 Fitting the filter bracket
I
CAUTION!
f Before installation, read Technical data (Chapter 2) and Operating/Safety instructions
(Chapter 4).
f To connect the filter system to the appliances only use hoses according to DVGW W 543 or
NSF 42/53.
f When installing accessories (hoses, connection sets), observe the installation dimensions and
bending radii.
To install the filter system, choose a location that enables simple connection to the water
mains.
The bracket has to be aligned and mounted to allow a convenient access and replacement of
the filter cartridge.
The filter system must be securely bolted to a wall using the bracket.
The filter system should be operated in a vertical position.
