Been installing Generacs since 1997.Yours was a replacement?
New unit installed last fall.He might be talking about an H panel
I took air cooled in 2009 because my clients wanted me, not someone else doing their service, commercial 1 in 2011, and Protector Diesel in 2013.I just took the liquid cooled class this summer and bought the parts kit a couple weeks ago. It is a learning process for sure. More parts to contend with on the liquid cooled. More service than installs, supply house referrals.
