3. Applications
The filter systems are typically used to feed the following appliances:
3.1
Claris ULTRA 170, 250, 500, 1000, 1500, 2000 cartridges:
•
Coffee and espresso machines
•
Drinks vending machines (also cold & hot combination machines)
•
Ice machines
3.2
Claris S, M, L, XL, XXL and Claris PRIME:
•
Combi - Steamers and Self-Cooking Systems with direct water injection
•
Steam Cookers and Steam Ovens with boiler system
•
Coffee and espresso machines
•
Hot drinks vending machines
4. Function
The filter cartridges use ion-selective filter medium to reduce the carbonate hardness and the TDS of potable water.
The DuoBlend® bypass valve in the filter head can be used to precisely adjust the carbonate hardness of the filtered
water (with Claris PRIME cartridge to additionally adjust the Chloride, Fluoride, Sulphate and Sodium levels) to adapt it
to the application and type of machinery.
The filter material also reduces heavy metal ions like lead*, copper* and cadmium*.
The integrated active carbon block reduces undesirable cloudiness*, organic impurities*, odour and taste and chlorine
residue from the filtrate and bypass water.
* not performance tested or certified by NSF
5. Installation and Bypass level adjustment
5.1
Determining feed water quality parameters
5.1.1 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.
For Claris S to XXL and Claris ULTRA 170 to 2000 we recommend to add 2° KH / 2° Clarke / 30 PPM / 3° FH to the
value determined in order to compensate measuring errors of the test kit and for fluctuations in the quality of feed water.
For Claris PRIME use the exact measured carbonate hardness level. Use this value to determine the recommended
bypass level setting according to chapter 5.2 and for the determination of the filter capacity according to chapter 5.3.
5.1.2
Determining the chloride concentration and TDS level
Only required for the bypass level setting and capacity determination of the Claris PRIME cartridge!
Use a corresponding test kit to determine the chloride level in the feed water or contact your local water supply
company and ask for the chloride level in their supplied water.
Use a TDS or conductivity meter to determine the TDS in mg/l or the conductivity in µS/cm.
Use the chloride and the TDS/conductivity values in combination with the carbonate hardness level information to
determine the recommended bypass level adjustment according to chapter 5.2 and for the determination of the filter
capacity according to chapter 5.3
5.2
Bypass level setting
The unique DuoBlend® bypass valve technology enables precise adjustment of carbonate hardness and TDS (with
Claris PRIME to additionally adjust chloride, fluoride, sulphate or sodium levels) in the filtered water. It is possible
to adjust the bypass level to best suit the appliance type and application, i.e. hot drinks with steam (COFFEE-
ESPRESSO), without steam (VENDING), Ice machines, as well as Combi Steamers or Steam Cookers.
The DuoBlend® bypass valve in the Everpure Claris Head Gen2 is preset to level 5 for the easy use in combination
with Claris ULTRA filter cartridges for hot drinks applications. If used with the Claris ULTRA cartridge series for hot
drinks applications, the bypass level 5 already fits to the carbonate hardness range of most common available feed
water. Check appropriate level in chapter 9.
For Claris and Claris ULTRA only the carbonate hardness level is required to determine the specific bypass setting
level and the capacity for specific appliances and applications.
For Claris PRIME the following 3 paramaters are required to determine the bypass setting level and the capacity:
TDS/conductivity, carbonate hardness and chloride levels for specific appliances and applications.
