Hello... I have one of these in my system - trying to decipher the dial
markings. It is gradated from "90 deg./closed" to "0 deg/open" and then
around to another instance of "90 deg/closed" - if anyone is familiar with
this particular unit and could say whether "closed" or "open" is the setting
for maximum aeration, I'd appreciate it.
This links to a small pic of the unit...
The manufacturer is the www.clackcorp.com but I don't know if they have
anything on their web site about it. I don't know when you get the most air
(suction) but I don't think it's when it's fully open. Call the dealer you
bought it from or find one that uses air injection and ask them.
