naperenterprise,
I have the same unit and you will enjoy it. I had only 45psi at the unit with my supply line where its installed so I ended up adding a booster pump and now spit out 5 gallons every hr. I`m happy with it. Great customer service from them also if ever needed
The air in the last cylinder DI will gradually go away. Its trapped air in the unit from install. Mine does that when I install new filters and gradually will disappear over time.
