Impurities are separated by the combined action of water centrifugal force, a magnet and a metal filter. They can be then discarded by the drain cock. The special adjustable fitting enables to install the dirt separator under-boiler, on horizontal, vertical, angled and also 90°-angled pipes.

A metal filter below the cyclonic chamber holds the impurities decanting from the chamber itself on the bottom of the separator. The dirt separator features a screw on top which releases air upon initial operation (see “Installation” paragraph). The separator can be cleaned without being disassembled and/or switching off the system by opening the drain cock on the bottom of the separator (see “Maintenance” paragraph).

Connect one inlet and the outlet of the inlet/outlet fitting to the heating system and screw the cap included with the dirt separator (only for 3/4” and 1” versions), on the unused inlet. The main body should always be in vertical position with the drain facing down.  WARNING. The dirt separator is equipped with a magnet that causes magnetic fields , which may damage electronic devices (pacemakers included ) near the circuit.  Installation In order to protect the boiler from the impurities in the heating system, the dirt separator must be installed on the heating return circuit. The 3/ 4” and 1” versions, thanks to their compact size enable to install them right under a wall-mount boiler. The 1-1/ 4” version, thanks to the greater water flow, is used in heat pump systems. Leave a free space on the upper side of the separator, at least 50 mm, to easily remove the magnet.  NOTE. To facilitate maintenance operations, it is recommended to install a shut-off valve upstream and downstream of the R146C dirt separator. Heating system return Heating system delivery Domestic cold water Domestic hot water Gas supply Air vent screw On top of the dirt separator is a screw to vent air from the system during the start-up (Components - Ref.6). Release the air by turning the screw in counterclockwise direction with a 5 mm Allen wrench. Tighten the screw clockwise once the air has been removed. 5 mm

The dirt separator requires no shutting off and disassembling to be cleaned; however we recommend carrying out these operations with no flow inside the dirt separator. To clean the separator and remove impurities, follow the steps below: 1) close the shut-off ball valves upstream and downstream the dirt separator; 2) pull out the magnet from its housing by unscrewing it in counterclockwise direction with a 5 mm Allen wrench; the impurities collected on the housing surface will deposit on the bottom of the separator; 3) after a few minutes, take the cap from the drain cock, and place it on the bottom of the cock, then rotate counterclockwise to open the drain cock and discharge the impurities in the dirt separator; 4) once the impurities have been removed, close the drain cock and reinsert the magnet in its housing, screwing it in clockwise direction; 5) open the shut-off ball valves upstream and downstream the dirt separator and restore the normal operation. 5 mm CLOSE CLOSE CLOSE CLOSE OPEN OPEN 5 mm CLOSE CLOSE CLOSE CLOSE 1 2 3 4 5 How to clean the metal filer (Components - Ref.3) For a more thorough cleansing, proceed as follows: 1) turn off the system and close the shut-off ball valves upstream and downstream the dirt separator; 2) unscrew the dirt separator base in counterclockwise direction; 3) remove the filter from the dirt separator and wash it under running water; 4) fit the filter back in and screw the separator back on its base. 5) open the shut-off ball valves upstream and downstream the dirt separator and restore the normal operation.
