Which way does my Watts Pure Water RO auto shutoff valve go?

[Xr280Xr]

I can't figure out which direction the auto shutoff valve for my Watts Premier Pure Water RO system is supposed to attach. Here is the diagram they provide:

and here is the actual part:

I've been reading conflicting information on whether the tank and inlet line belong on the "In" side or the "Out" side of the valve, and on each of those, I'm not sure which tube goes in the top or bottom connection. If I had it connected incorrectly, did I destroy the valve?

call the 800 # for tech assistance

I found another diagram. The green tube (from adapt-a-valve and to filters) goes on the labled side of the auto shutoff valve and the blue tube (to/from tank/filters) goes on the unlabled side with the screws. The adapt-a-valve and tank tubes go on the "In" side and the tubes to the filters on the "Out" side.

Initially I had In and Out correct, but the blue and the green reversed so I'm not sure if that damaged it.

I'm going to guess that it wouldn't matter....UNLESS there are arrow indicators on the part. Looking closely at the first pic showing the shut off valve, it appears there is a difference from the left to the right sides. Yeah, a phone call to the manufacturer may be in order.

the drain on this thing, is a total health hazard.

it calls for the drain to DIRECTLY hook to the waste system.

these are my thoughts on that.

your sink backs up. sewage water WiLL back up into the drain line connected to the faucet.

lets say, your plumber or the city turns off the water meter outside to preform maintaince

you walk in the kitchen and turn on the faucet.

BINGO....you just caused a negative pressure condition, the sewage water will be back syphoned into the filters.

when the water meter is turned back on, your first drink will be

sewage..mmm....yum yum....

excuse me dear, would you like a refreshing glass of pee ?
how about a cup of hot poo poo cocoa ?

I could be wrong >>>IF<<< it is equipped with an air gap fitting

I just installed one last week and it is equipped with a built in air gap.
