JURA water-filtering system
ZIf the filter cartridge has been stored below 0 °C, it must be
stored at the ambient temperature of the installation location for
at least 24 hours before installation.
EThe pipes for the supply and discharge lines are not supplied as
standard but can be ordered as accessories. You will find more
information in chapter 7.
4.2.1 Installing the filter head with wall mounting
bracket and filter cartridge
EThe system can be operated in a free-standing position,
wall-mounted in a vertical position or horizontally.
TIf mounting to a wall: Securely fasten the wall mounting bracket
to the wall using suitable screws (not supplied as standard). The
dowels and screws must be selected in accordance with the con-
dition of the wall.
TInstall the water inlet and outlet pipes at the filter head. When
doing so, please note the following points:
ZNote the direction of flow (see markings on the filter head)
ZMax. torque when using genuine CLARIS connection pipes
(accessory): 10 Nm.
ZFilter heads with 3/8" threaded connections must only use
connectors with flat seals. Do not use pipes or adapters with
conical screw connections, as they damage the connections
and invalidate any warranty claims.
ZOnly use screw adapters of a suitable type and appropriate
length. When unscrewed, they must not rest axially on the
filter head. Unsuitable adapters can damage the connections
and invalidate any warranty claims.
TDirect the flush pipe into a suitable container (e.g. bucket) or
into a drain and open the flush valve (4).
TTurn on the water supply again.
TInsert the filter cartridge into the filter head. Take note of the
insertion marker (8) on the filter head and the marker on the fil-
ter cartridge (9).
TTwist the filter cartridge anti-clockwise until the end position is
reached. The marker on the filter cartridge should now be in line
with the operation marker (10) on the filter head. This vents the
system and flushes the filter cartridge (F2300/F3300 > 10 l,
F5300 > 15 l).
TClose the flush valve.
The water-filtering system is now ready for use.
TAfter installing the system and inserting or replacing a filter
cartridge, check all components for leaks. Water must not
escape from any point.
4.2.2 Replacing a filter cartridge
TPlace a container under the flush pipe.
While the filter cartridge is being replaced, the automatic coffee
machine and the water supply line are hydraulically disconnec-
ted from the filter head and the system depressurises.
Minimum quantities of water may therefore escape from the
flush pipe due to peaks in pressure.
TSlowly unscrew the used filter cartridge in an anti-clockwise
direction.
This will unlock it from the filter head and allow it to be removed.
TDirect the flush pipe into a suitable container (e.g. bucket) or
into a drain and open the flush valve (4).
TRemove the new filter cartridge from its packaging and check it
for damage.
TInsert the filter cartridge into the filter head. Take note of the
insertion marker (8) on the filter head and the marker on the fil-
ter cartridge (9).
TTwist the filter cartridge anti-clockwise until the end position is
reached. The marker on the filter cartridge should now be in line
with the operation marker (10) on the filter head. The flow in the
filter head is reopened and the system is vented and flushed via
the flush system (F2300/F3300 > 10 l, F5300 > 15 l).
EThe flush water will be milky or cloudy at first. This is due to the
dispersing air and will not take long to clear.
EPay attention to the position of the label when inserting the fil-
ter cartridge. The label should face forwards so that all of the
necessary information is visible.
TClose the flush valve.
The water-filtering system is now ready for use again.
TAfter replacing the filter cartridge, check all
components for leaks. Water must not escape from any point.
4.2.3 Setting the bypass level
EWhen using the water-filtering system, we always recommend
bypass level 1.
4.2.4 Determining the filter capacity
Based on the local carbonate hardness of the mains water and of
bypass level 1, use the tables in chapter 8 to identify the resultant
filter cartridge capacity.
Please enter the installation date and time of replacement in the
corresponding fields (on which it is possible to write in pen) on the
filter cartridge label.
5 Service / maintenance
The system will only function safely and reliably if the filter cart-
ridge is replaced on a regular basis. The replacement cycles depend
on the carbonate hardness of the potable water, the application
and the set bypass level (we always recommend bypass level 1).
We recommend replacing the filter cartridge after 6 months and
no later than after 12 months.
The operator must check the system for leaks everyday.
When replacing the filter cartridge, check all parts for impurities
and damage. Damaged parts must be replaced and impurities
removed.
