need instructions(pic) for aqua chiller

[wolfie]

Got my chiller yesterday and was going to set it up now, but the instruction that ame with the chiller only showing me how to program the chiller, but does not said about holes connection and I have no way knowing which inlet is the in and which is the out.

I am stuck as of now since I how no clue which are which and I do not want to redo the plumping after it is set up

thanks

Never mind.
I get to thinking that the reason that there are no inlet nor outlet is because either 1 could be use as in or out.
