if you figure out how to do it,
please let me know.....I have always wondered
how the hell it was supposed to be accomplished.
something to do with running vinegar through
the unit to get the lime out.....
I know if you install boiler drains (laundry hose faucets) on
both the inlet and outlet sides of the unit
with ball valves to isolate the unit , it makes it
pretty easy to flush the vinegar through the thing.
and then you are prepaired
for the next time it has to be done.
ya just gotta love high technology.
