Dosage Instructions
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.
