I. Presentation of the magnetic filter

The magnetic filter MG1 by RBM has been designed to efficiently extend the lifetime of your boiler.

Composed of a bidirectional magnet which pulls and holds all the impurities, and a cartridge inox (filter), this magnetic filter allows to fight against the corrosion.

If you can isolate the installation area of the MG1, follow the procedure below.

The magnetic filter RBM does not require a big maintenance. Find the magnetic filter MG1 on our website under the reference 110010.

Before proceeding with the installation of the MG1, there are 3 possible situations :

• Your installation is new. You can install the MG1
• You have an old installation (> 10 years) but you recently demisted your heating. You can install the MG1
• Your installation is old (> 10 years) and you have never demisted your heating circuit. Before installing the MG1, we suggest to demist your heating circuit and to insert an anti-corrosion product. For more information, read our tip-sheet.
