We had our sog fitted by the converter of our mhome but there were no instructions on maintenance spare parts etc. We emailed this company asking for some instructions on the maintenance & spares etc. They did reply but with installation instructions. Not quite what we wanted.
Perhaps it was other halfs attempt at speaking German.
Regarding the sog. Much much better. No chemicals to bother with & no chemical smell. Best of all no unpleasant smell from the unit either. We do tend to empty it daily though whenever possible.
