A sink in between the deeptank and the Wing Lynch. For one thing--you need clearance space around these processors to get at the sides & backs of the machines. You don't want to cram them into a corner that makes it impossible to service them for maintenance--AND--they'll need certain heights for drainage. Then, I guess it depends on what tank size you have in the WL, but you'll be mixing up gallons & gallons of color chemistry. A dedicated sink is really nice for this. The color stuff will be the worst. Having the processors in their own little area, might make it easier from a ventilation design--you might be able to isolate them somehow. You might also be able to gang them up on the same water panel--of course you couldn't use them at the same time probably. You'll need to have vac. breakers on the water line running into the processors--probably at the water panels, and check valves as well. This is for safety. I would make sure you have a free hose on a cold water line at all times for a makeshift eyewash--or get an eyewash or a portable one and put it in on the wall next to the processors.
the other thing is to rethink the batch processing. This will be time consuming(not to mention costly) to mix up fresh for a day and then dump. Those machines are better left with the chem loaded in them, than left dry. Then, each tank is probably--what?-how many gallons? Then, the repl. tanks. It would be better to establish some sort of routine where you can run the machine every other day or something. It's like money down the drain really--a machine is great when you need to print all day long or process film, but they're a money pit when they sit idle.
btw--if you lived in my area, I'd loan you these books--but I'm thinking you oughta be able to find them in a library or maybe get some similar info from an occupational safety agency--like your local labor dept. website--this is basically osha, niosh type stuff. Kodak had a great publication on commercial lab design year ago. "PhotoLab Design", pub. K-13 (here again, we have a copy or two in our library). It has scale drawings of lab layouts and all sorts of specs on their design and construction. Probably out of print now--but they have other tech publications as pdf's on this site:
kreonite might be another place to try for advice--at least on what it would take as far as installation for the hope. you might want to look into how much fix you can legally dump in your area as well....
just a thought--KT
