RO/DI installation

[ToX]

I just bought a aquasafe ro/di unit. First of all, I was wondering if i could use a faucet adapter for the IN and just trow the drain line in the sink. I really dont want to drill holes (1 im afraid i'll cause a flood and 2 its my parents house and i'll be moving next fall).
Secondly, the RO I bought differs slightly from the one in the picture of the "installation emailed" lol . I would really appreciat if someone could post a picture of where all the tubes go. ( i have a round four way connector)
