Just when I think I have seen all of the failed attempts at building a 21st century self serve system, along comes this thing. My customer has one. Everything is controlled by computers (so you know it's smart) and the high pressure pumps deliver all products except the spot free. The owner has flat given up on D/H (thank you Harry Bauge for taking another company down the drain). Their tech support simply cannot figure this out. It was sold and installed by the former PDQ distributor who now runs Coleman. Their techs are still around but have had no success in getting two of the five bays running. Other companies have also been left in the dust. So now it's my turn. There are no manuals left from the installation. It was, and may still be, common practice to NOT leave any manuals for the equipment just installed new. That way, don't you know, most operators have to call foe service. So my question is, is there anyone out there who knows how this stuff is supposed to operate? Also are there any manuals or electrical schematics? Am not asking for free advice or manuals. Will pay if you have them. My only option at this time is simply to rip out the D/H crap are rebuild it as normal self serve stuff.
