11.4 - Watersoft N electromagnetic water treatment device
The device for electromagnetic water treatment, Watersoft N, uses no chemicals. It softens water, prevents
scale formation and dissolves existing sediments. It is particularly suitable for use with devices with thermally
stressed spots like heat exchangers and storage water heaters. Among its advantages is a quick and easy
installation, no need for plumber’s intervention and min. operation costs (consumption of el. energy 2W).
11.5 - Additives for heating systems
MR-501/F
Protective liquid made of organic compounds, intended for use in heating and cooling systems, solar collec-
tors and heat pumps. It prevents corrosion of metals (iron, copper, aluminum etc.) and their alloys by creating
a film on the surface that is in touch with the heating liquid. It can be mixed with antifreeze fluids. Recommen-
ded use: after cleaning the system with M 501/R.
MR-501/96P
Liquid agent of balanced efficiency for underfloor heating, solar panels and plastic piping. It creates a prote-
ctive film and prevents growth of algae and gas formation. The system is also protected against calcareous
sediments. This well-balanced mixture of corrosion inhibitors and protective film creating compounds ensures
a max. protection of underfloor heating and solar panel circuits.
MR-501/R (1kg)
Concentrated alkaline anti-corrosion liquid removing scale and calcareous sediments from heating systems.
It dissolves scale and rust and makes it possible to remove them by flushing the system. 2 liters of MR-501/R
shall be added to every 80-100 l of heating water and let to act for 2-3 weeks depending on the degree of sedi-
mentation. Then the heating system shall be drained and flushed. When filling new water, it should be treated
by adding the protective liquid MR 501/F.

11.3 - Tube heat exchangers and their mounting flange
When needed, a finned tube heat exchanger may be installed into the appropriate flange (code 8375), into the
lateral inspection hole instead of a plug.
