The IK ion exchange cartridge is designed for filling with ion exchange resin. It can be filled with the available ion exchange resins: e.g., for softening, "Ion Exchange Resin GH" (total hardness) or "... KH" (carbonate hardness): Reduces water hardness. For very hard water, approximately 100 liters capacity. For nitrate removal, the "Nitrate" ion exchange resin is available.

The ion exchange resins GH and nitrate can be regenerated using the regeneration adapter IK-NF2 (Art. No. A20-066) and commercially available regeneration salt.

Areas of application

- with GH or KH resin: Water softening for drinking purposes (not for domestic use). Depending on the resin, the total or carbonate hardness is reduced; there is no pH reduction (unlike pitcher filters).

- with resin nitrate: nitrate reduction

The IK-NF2 can be used in the CARBONIT filter units...

• VARIO HP
• CITO QC
• DUO HP

The cartridge is adjusted to the incoming water hardness via bypass holes. A test strip is included with the cartridge to measure the incoming water hardness.

Notes

Flow limitation to D=1 l/min is recommended; higher flows are possible but reduce the extraction capacity.

For technical reasons, use is only permitted with cold water and must be protected from frost.
