Dosage Instructions
Maintain peak performance
500ml of MC1+ treats 125 litres or 15 single panel radiators. To introduce MC1+ into the system we recommend using the MagnaClean® canister to dose the system. Alternatively dose via a radiator or the F&E tank. MC1+ levels should be checked regularly during annual system service, or following any system maintenance requiring full or partial drain-down. If you are unsure of which chemical is in the system, perform flush prior to adding the recommended amount of MC1+. Do not use in single feed indirect cylinders.
Homeowner benefits

- Maintains heating efficiency
