Replacing a filter cartridge
1) Slowly unscrew the used cartridge by turning counter-clockwise. This will unlock it from the filter head and enable it
to be removed. During this process, incoming tapwater supply and outgoing filtered water valves in the filter head
shut-off automatically.
The system will expand and a small amount of expansion water may escape from the flush hose due to peaks in
pressure. Please keep this in mind and place a suitable container underneath the flush hose.
2) Open the flush/pressure release valve (see page 3, A 6) and lead the rinsing hose into a suitable container (e.g.
bucket) or to the drain.
3) Remove the new filter cartridge from its packaging and check for any damage.
4) Insert the filter cartridge into the filter head and turn the cartridge clockwise until it stops and end position is reached
(see page 3, position 8). The flow in the filter head is reopened and the system vented and flushed via the flush/
pressure release valve. Flush filter type S,M > 5 l / 1.5 US gal; filter type L,XL > 10 l / 3.0 US gal; filter type XXL >
15 l / 4.0 US gal).
Flush filter type ULTRA 170, 250, 500 > 10 l / 3 US gal; type ULTRA 1000, 1500 > 20 l / 6.0 US gal; type ULTRA
2000 / Claris PRIME > 30 l / 8.0 US gal).
5) Close the flush/pressure release valve (see page 3, A 5) - the system is now ready for use.
6) After replacing the filter cartridge, check all components for seal integrity, water must not escape from any point.
NOTE: The flush water will be milky or cloudy at first. This is due to the dispersing air and will clear up quickly after
flushing the cartridges with appropriate volume of water. Now check that the cartridge position is correct by ensuring the
mark on the filter cartridge aligns with the larger recession of the wall mounting bracket (see page 3, position 8). When
inserting the cartridge, check the position of the cartridge label. This should face forwards once in the end position so
that all of the necessary information is visible.
6. Service / Maintenance
Reliable system function can only be achieved if the filter cartridge is replaced on a regular basis.
The replacement cycle depends on the carbonate hardness (for Claris PRIME on carbonate hardness and TDS/
conductivity) of the water supply, the application and the bypass level.
We would recommend replacing the filter cartridge after 6 months and no later than 12 months depending on usage.
The operator undertakes to check the system for leaks every day.
When the filter cartridge is replaced, all parts must be checked for impurities and damage. Damaged parts must be
replaced and impurities remedied.
