Dosage instructions
Maintain peak performance
For detailed instructions for use, refer to the instruction leaflet
enclosed within the MC40+ Cleaner and Descaler box. The cleaner can be
added slowly in small amounts as a free-flowing powder into the
RapidFlush canister, when completing a MagnaCleanse®, or directly into a
mechanically assisted flushing device. Alternatively, by adding MC40+
to warm water and agitating until the powder is dissolved, the cleaner
can be introduced via the filling loop or radiator using a suitable
injector, or via a MagnaClean® filter. For open vented systems, the
product can also be added via the F&E tank.
High-performance MC40+ is a
concentrated, advanced cleaner, as one container treats 125L. For
larger, more heavily scaled systems, additional MC40+ may be required.
The time needed to complete the clean is dependent on system condition;
however, the product should not be circulated for more than four hours.
Once MC40+ has been adequately circulated, and if the system water
remains red, add the sachets of neutraliser to the system until the
water turns yellow. If the water remains red in colour, a further
neutraliser is required. Following adequate system circulation, dispose
of the system water appropriately, in accordance with local disposal
regulations. Flush the system until the water is clear. Add the correct
dosage of MC1+ Protector for the optimum protection against the build-up
of corrosion and limescale.
NOTE: Product may cause slight
staining to MagnaCleanse® hoses or canisters. Performance of the
MagnaCleanse® will not be affected.
