CLARIS ULTRA 1500
Adjustable ion-selective filters to tailor carbonate hardness levels in potable water. Part number: 4339-83
The Claris series filter cartridges are only compatible with the CLARIS heads designed for them. In all cases, the cartridges can be connected to the water network with the help of the Claris heads. They cannot be used on their own! You can find more information about the heads on the CLARIS HEADS page.

FEATURES • BENEFITS
Removes harmful
contaminants and unpleasant
odors and tastes
Removes particles down to
five (5) micron for highest
equipment protection
Operation in vertical or
horizontal position
Unique water conditioning technology combines mineral adaptation, mineral stabilization and corrosion inhibition
Features a 5-stage filtration process that includes:
- Prefiltration
- Carbonate hardness adjustment
- Fine filtration
- Highly efficient carbon block
- Solid membrane filter
The contaminants or other substances removed or reduced by this drinking water system are not necessarily in your water. Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.
Specially selected filter fleeces hold back dirt and particles, thus providing lasting filter protection even when water quality is poor.

INSTALLATION TIPS
- The system can be operated freestanding, lying horizonally or mounted vertically.
- If mounting vertically to a wall, securely connect the mounting backet to the wall using suitable screws.
- Water pressure at the filter system inlet must not exceed 8 bar (116 psi). A pressure reducer valve must be installed on the water supply side of the filter system if the inlet pressure exceeds 8 bar (116 psi).
- Shutoff valve must be installed upstream of the filter.
- Refer to Installation, Operation & Maintenance Manual for cartridge flushing and startup.
OPERATION TIPS
- Change Claris Ultra Cartridges when its pre-calculated water volume has been reached or at least once per year.
- Change cartridges when capacity is reached.
- Always flush the filter cartridge at time of installation and cartridge change.
- Do not use hardness test strips to check for hardness reduction. Please use the Claris Titration Kit to check for hardness reduction.
