NOTE: The fl ush water will be milky or cloudy at fi rst. This is due to the dispersing air and will clear up
quickly. Now check that the cartridge position is correct by ensuring the marks on the wall mounting bracket and fi lter
cartridge are aligned (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.
5.2.3 Determining the carbonate hardness
Use the corresponding test kit to determine the carbonate hardness in the water supply. A test kit for determining
water hardness is available as an accessory.
In order to compensate for fluctuations in the quality of feed water and measuring errors of the test kit we
recommend to add 2° KH / 2° Clarke / 30 PPM / 3° FH to the value determined.
Use this value to determine the recommended bypass level setting according to chapter 5.2.4 and for the
determination of the filter capacity according to chapter 5.2.5.
5.2.4 Bypass level adjustment
NOTE: Adjust the bypass level only with the cartridge assembled to the head.
To adjust the bypass level for your application, lift up the bypass adjustment cap (see page 3, position 4) and set
the bypass level specified in the table in chapter 10. Then push down the bypass adjustment cap back onto the filter
head to lock the cap in position.
5.2.5 Determining the fi lter capacity
Based on the carbonate hardness level of the water supply and your application, use the tables in chapter 10 to
identify the recommended bypass setting and the resultant filter cartridge capacity.
Please mark the installation and replacement dates in the corresponding boxes on the cartridge label.

6. Settings / Capacities

The unique DuoBlend bypass valve technology enables precise adjustment of carbonate hardness in the filtered
®
water. It is possible to adjust the bypass level to best suit the appliance type, i.e. hot drinks with steam (COFFEE-
ESPRESSO), without steam (VENDING), as well as for Combi Steamers, Self - Cooking Systems, Steam Cookers
and Ovens whether using direct injection or boiler systems, in order to maximise cartridge capacity taking into
consideration local water quality.

7. 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 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.
