DILLING-HARRIS - Spot free rinse

[ready2go]

Hi I recently bought a carwash oilchange business and my spot free rinse from dilling-harris seems to have no pressure and i cannot find any documentation online. does anyone have any ideas of what my problem is or where i can get materials to figure out whats going on.

thanks

Where are you located

The pumps they use need to be primed. Try that first, make sure the tank is as full as possible, disconnect the outlet and let the water flow until there's no more air, then turn the pump on for a couple seconds at a time until it's flowing as strong as it will get, might take three or four tries. If that doesn't work, good luck, their RO systems are a nightmare of plumbing and valves because they have them flush the membrane with clean product water. Rather than trying to fix it I'd recommend unplumbing everything and redoing it as simple as possible. I usually pull about ten pounds of brass off of them when I replumb.

There's an old Dilling and Harris RO Machine not being used . If you should need any parts it's not far from me .

I have all the DH factory manuals for the system. My issue is its been turned off for three years and the previous owner passed away and never told me how to operate it. Picture below. If anyone knows how work it and get it started back up it would be much appreciated. I assume it uses salt as well. Feel free to PM too.Thanks David

It doesn't use salt, just turn it on and it should do what it's supposed to.
