Replacement cartridge for both 15mm and 22mm Combi-Care dosing system. Food grade polyphosphate needs to be replaced every 12 months. Recyclable can, where facilities exist. 

Care should be taken when replacing the cartridge. The water supply must be switched off and any residual pressure relieved before starting work. Once the new cartridge is fitted the date ring should be reset and the installation checked for leaks. Max working temperature 30 c. Please note: These units will be affected by hot water transfer back down the system, therefore they must be installed as far away from the boiler as possible (minimum 1m). Do not install where ambient temperature is likely to exceed 35c. Notes: Please do not over tighten fitting or use a pipe wrench on body of the canister. Unit must continue to be adequately supported on both sides of the installation and correctly aligned to avoid stress to the unit or joint. Protect form freezing.
