Dosage instructions
Maintain peak performance
500ml of MC1+ Protector treats 125 litres of heating system water, the equivalent of 15 single panel radiators.
To introduce MC1+ into the system we recommend using the MagnaClean® filter canister already installed on the system. If no filter is present, 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 a flush prior to adding the recommended amount of MC1+. Do not use in single-feed indirect cylinders.
