Auto Tank Drains

by Air Shops / Il.
(Elgin , il. )

I'm trying to install a Kingston 621-4-4 , but the ATD came with NO directions . I assume the 3/8" end should be connected to the bottom of the tank . I have run a copper tube from the port on the check valve ( at the top of the tank ) down to the bottom of the tank and screwed it into the Kingston ATD .


Not knowing if I did this correctly , I stopped . I'm awaiting further instructions !
