My company has received a deionized water system that at one time was operating. It was delivered completely disassembled with no instructions. We are no water filtration experts, so we don't really know how to go about installing the system as there are many different parts. It would be extremely helpful if someone could provide help on how to arrange these different parts. I have attached pictures. We have 4 tall filtration tanks. 2 of the tanks are labeled as h-18 carbon filters and the other 2 are labeled as h-18 in softener. It appears there is an RO unit as part of the system. Any help would be appreciated!

* disregard the picture of the pump. (belongs to a separate system)
