Dosage instructions
Maintain peak performance
500ml of MC5 will provide effective treatment for a typical 100
litre/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.
By increasing the system water temperature, the performance of MC5 is enhanced.
MC5
can be left in the system for up to seven days. When using MC5 in
conjunction with MagnaCleanse, the addition of heat 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.
Do not use in single feed indirect cylinders.
