LIMESTONE REMOVAL AND ANTIOXIDISING PRODUCTS<br />
For Limestone Removal <strong>of</strong> Radiators.<br />
Kit for Limestone Removal and Neutralisation.<br />
> CALEX DOSA-NEUTRE Ref. 4095<br />
Description:<br />
The CALEX DOSA-NEUTRE Kit contains 1 l limestone solvent and ½ l neutraliser.<br />
The limestone removal solution is an acid solution dosed for dissolving 150 g limestone in 15 minutes.<br />
The limestone removal solution has colorimetric indicator.<br />
The neutraliser allows the reduction <strong>of</strong> the dissolving solution to a neutral pH-value in order to dispose<br />
it in the canalisation.<br />
Application mode:<br />
1. Connect the inlet and outlet <strong>of</strong> the warm-water heat exchanger at the <strong>pump</strong> (see diagram 1).<br />
2. Fill 3 l <strong>of</strong> water in the <strong>pump</strong> tank TUBNET CLASSIC.<br />
3. Put the valve into an intermediary position.<br />
4. Put the <strong>pump</strong> in function and reverse the circuit direction turning the position <strong>of</strong> the valve from left<br />
to right.<br />
5. Check if the water circulates and if the connection parts are pro<strong>of</strong>ing.<br />
6. Progressively introduce the limestone removal product.<br />
Observation: The limestone removal product hat colorimetric property. When there are no more gas and the colour <strong>of</strong> the removing<br />
solution stays yellow, the limestone removal process can be considered finished.<br />
7. In order to respect the present rules the pH-value <strong>of</strong> the residues must be between 6 and 8,5.<br />
Before disposal we recommend neutralisation.<br />
8. Restart functioning: when the heat exchanger restarts right away, rinse with clean water.<br />
