Doser 2.1 versions?

AZMSGT · Sep 14, 2019

@Ditto @Vinny@GHLUSA Today I picked up a Doser 2.1 today. It’s an older one. As I understand there where different heads on the older ones. Not sure if that’s true...
Can anyone confirm if this unit is good or do I need to update anything? I’ll get the firmware done soon.

The newer covers have a small raised bump in the right hand corner on the front cover (from memory as I'm not at home to check). Hard to see if the ones in the pictures do.

For good order you should remove and clean the inside of the blue cover and all the rollers. If the age of the doser is unknown, then you should consider buying the head servicing kits and replacing all the rollers/covers.

No raised bump that I can find. Yep, I agree the previous owner said they didn't use it much. I took the heads apart last night and looked everything over. I pulled all the tubing and trashed it. Not sure what they had in them. The parts are cheap enough to replace and not take a chance.
