Level 2 Cleaning - DCL MINE-X SOOTFILTER Accompaniment To The Installation, Operation And Maintenance Manual

4.4 Level 2 Cleaning

1. Remove the DPF from the application. If it is a standard design, simply remove the quick-release
clamps. If it is a custom designed DPF muffler such as Figure 4.1 or Figure 4.2 above, remove the
DPF muffler in the same manner as the original equipment muffler. For removal of other custom
designed filters, contact DCL as necessary.
2. Place the DPF centrebody, inside an oven or kiln ensuring that the inlet and outlet of the DPF are
exposed. i.e. Do not sit the DPF vertically in the oven so that the DPF inlet or outlet filter faces are
against the surface on which the DPF is resting.
3. Increase the temperature of the oven to 500°C over a period of 1.5 – 2 hours.
4. Retain an oven temperature of 500°C for a continuous period of 4 hours to allow complete combustion
of accumulated soot in the DPF.
5. Decrease the temperature back down to a temperature that will allow for safe removal of the DPF by
hand.
6. Remove the DPF from the oven and perform a Level 1 Cleaning to remove the noncombustible ash
content.
7. For standard DPF designs, reinstall DPF centrebody into position on the application. For custom
designs, either reassemble muffler by placing the DPF centrebody into muffler and clamping or bolting
it into place, or reinstall the muffler end-disc by bolting it to the muffler.
8. For custom design muffler replacements, reinstall the DPF muffler back into the application in the same
manner as installing the original equipment muffler.
