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 a maximum of 7 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.

How to use
500ml of MC3+ treats 125 litres or 15 single panel radiators. Introduce
MC3+ to the system via the filling loop or radiator using a suitable
injector, or via a MagnaClean® filter. For open vented systems MC3+ can
be added via the F&E tank, remembering to remove sufficient water
via the drain-point to ensure MC3+ enters the system circuit. By increasing the system water temperature, performance of MC3+ is enhanced.
Clean system as recommended in BS7593
using ADEY MagnaCleanse® and MC3+. For heavily sludged systems, ADEY MC5
RapidFlush System Cleaner is recommended. Cleanse, drain and flush
thoroughly until the water runs clear. Refill the system and add the
correct dosage of MC1+ for the optimum protection against the build-up
of corrosion and limescale.
Also available in the following sizes: 300ml, 5L, 10L, 25L, 200L and 1,000L.
Do not use in single feed indirect cylinders.
