You're probably like me and you don't want to read the instructions that came with it, do you have the instructions? if not you should probably try to get them from the manufacturer. You may get lucky and someone on this board will know how to hook up your specific model. Maybe you could even get them on the manufacturers website, or you could call the company and I'm sure they'd send em to ya. Sorry I can't be of more help. R/O units can be confusing to hook up sometimes.

All RO filters hook up basically the same way, water first goes into the sediment filter, then the carbon filter, followed by the RO membrane (the long thing on the top), and then to the DI filter (if you have a DI). Some manufacturers are also adding a second carbon filter either one right after the other or another as the last filter the water goes through. If you don't have the hook up instructions then I should also point out that there is a waste line on the RO cartridge that needs to be hooked up to a drain unless the filter is located in a place where the waste water won't cause a problem to run on the floor, this line is usually red in color and the final product line is usually blue. You should also know that there is a flow restrictor on the waste line. If you have any more questions on how to hook the unit up feel free to contact me and I will try to answer them for you. Good luck

Should have already basically come setup here are some pics of my setup maybe it will help understand.







I have alot of addons that you need to consider which will play a large part in your hookup if you have them or not. Like flush valve, gauge, addon DI filter, and boosterpump

I forgot to add

My red line is the input (tap water)
My green line is the clean output
My black line is the waste output

Scuba -

What is the center blue valve for? I have a 4 stage Oceanus, but don't have that. Is it some sort of flush valve? I'm trying to understand my setup, cause I need to reverse flush the RO membrane and can't figure out exactly how.
