11.1
Cleaning the probe
The probe of the Dumo can be cleaned with compressed air without any disassembly. Should the dust buildup
on the probe be stuck on so hard that cleaning with air does not remove the build-up, the front cover of the
Dumo can be removed allowing for proper access to the probe.
1)
Disconnect power to the Dumo
2)
Remove the 5 screws shown below:
Figure 22 Remove bolts at the front cover
3)
Remove the front cover
Figure 23: Cleaning the probe
4)
The probe can now be cleaned with soft brushes and mild solvents should the dust be stuck on. If the
Dumo is with the optional PTFE coated probe, do not use any abrasive cleaning methods.
5)
Close the cover with the screws removed in section 1. Make sure that the short internal duct section
does not fall of. Tighten the screws to max 7 Nm.
If you have a Teflon coated probe avoid using any other tools than fabrics for cleaning. The
Teflon coating may break.
If the dust build up is impossible to remove, pull off the complete outer Teflon sleeve and
replace it with a new Teflon sleeve.
The black surface under the sleeve is a second layer of very fine Teflon, which represents the
actual protection am may not be scratched.
