Dosage instructions
Maintain peak performance
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 BS
7593 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.
