How to use

500ml of MC5 will provide effective treatment for a typical 100litre/ten radiator system. For larger systems, use further MC5 as required.

For fast and effective results, we recommend introducing MC5 via the RapidFlush Filter canister during a MagnaCleanse® system flush. Circulate in the system for a minimum of one hour.

MC5 can be left in the system for up to seven days.

When using MC5 in conjunction with MagnaCleanse, the chemical enhances performance making the system cleansing process faster and more efficient. After cleaning, the system should be drained and flushed thoroughly.

Refill and provide long-term protection with ADEY’s MC1+ Protector.

N.B. NOT for use in single feed indirect cylinders.
