Jobo ATL-1000 rinsing water supply

[Martin Gorczakowski]

Hi everybody,
so I finally got myself a jobo atl 1000 processor, although I overpaid I am looking forward to finally developping my color 4x5" by myself. Anyway - I have some serious problems figuring out how to provide tempered rinsing water. The jobo water mixing panels etc, are no longer available, and are pricey none the less. However completing such a setup http://www.jobo.com/jobo_service_analog/us_analog/instructions/instructions_4167_water_heater_kit.htm is none of a problem. Will this be enough for tempering the water bath? I am thinking rather of using a water heater, which only heats the current water flow with a thermostat.
Another option would be just using a setup consisting of a mixing valve and a temperature display, I think it's called a water mixing panel (see http://www.picvault.info/images/537086993_463a_1.JPG).

How did you guys handle it?

Also - are you able to reuse chemicals from the c41 and e6 tetenal processes?

Thanks for all your answers in advance!

I have Hass Intellifaucet D250 mixing valve and it work great. A little pricey, but compensates for fluctuation in water temperature and pressure very well.

I have already seen the Hass intellifaucet, but it's just too expensive, almost as expensive, as the whole processor. I am looking for something more decently priced. Yet, thanks for your answer!

I use a faucet which was designed for a bathtub. It has one temperature knob on the top and two valves. One is connected to my ATL 1000 and I open up the other one a little so that there is an even (but slow) flow of tempered water. (I dont know what the faucet costs, as it came with a second hand wet bench with all the plumbing already done. Anyhow, these faucets should be available new or used at decent prices.)
It's definitely not an Hass, but it's good enough. Besides, the 2500 tanks are always tempered through both the chemicals and the tempered water inside the processor. For E-6 Jobo themselves say that +-2 deg C is OK for the rinse water (for C41 +-5 deg C) and I recon that at least my bathtub faucet is within E-6 range.

It's a bit messy to reuse the chemicals but it can be done. Maybe you should use a somewhat better hose (with smoother inside) for the chemical drains, so that there is less chance of chemical mixup., even though there is a rinse in between the dev.steps. (With my ATL 1000 I choose to use the chems one-shot. My next round of color processing will be done with a CPP2, where it's easier to take care of the used chemicals without any mixup, so maybe I will reuse the chems then, if there is much to be saved from it.)

Hi Bjorn,
This seems very reasonable. Although I will have to check the temperature every single time I run the machine I have estimated such an installation to be under 100$. I just think of installing two additional water filters in the system, just to eliminate calc etc in the rinsing water. I have already found the proper valves and thermometers.
All the best,
Martin

My domestic hot water supply is based on a gas instant water heater that takes time (30secs) to achieve a stable temperature. Although it is possible for me to stand in the shower waiting for the water to get hot, if I were to close and open the hot tap, the water would first cool then regain its temperature. How could I run off the cool water before allowing the thermostatic tap to take over at the start of each rinse cycle?

Or is there an inexpensive "instant" heater that would work?

This is the reason why I like my faucet which has two outlets. One coupled to the Jobo and the other is set to a slight flow, which keeps the temperature correct. (Nothing much, just enough to keep the temp stable, but not to drain the hot water supply.)

I concur Björn!

I run an ATL1000 and all I do is attach this type of adapter (http://www.compactappliance.com/ADAPTER-Standard-Quick-Connect-Faucet-Adapter/ADAPTER,default,pd.html?mtcpromotion=Become%3EAppliances%3ELaundry%3ELaundry_Accessories%3EADAPTER&src=BECOME) to my kitchen faucet, then to that I connect a dual valve (http://www.alwaysbrilliant.com/aa/aspx-products/1-7910/2-58285/SC-Froogle/kw-151101/bb/Garden-Hose-Shut-Off-Valves.htm) (mine is actually green plastic with brass insides) and connect the ATL hose on one side and allow a slow stream of water at required temp on the other. I have processed E-6 like this for many years with much success.

Actually the valves and thermostatic controls are still available. Omega Satter just decided not to sell them, but other companies do. You may even be able to get similar stuff through Calumet.

Nice and simple. That's what I should do if I didn't have that fancy chromed faucet already. (I got one of these Y-splitters outside for my garden hoses.)

I had a PM from a member that wanted to see my setup. I forgot to mention in my original post that I do use an inexpensive temp gauge (http://www.calumetphoto.com/item/DT2021/) connected to the apparatus.

that's a great solution darr, I will certainly use this kind of setup, at least until I get a decent place for my whole darkroom.
thanks a lot!

I have a jobo 2300, I found a mixing panel on EBAY, attached the hoses and was set.
it cost me like 55.00.

might check EBAY

So I just tried the machine, but as always something went wrong. First of all, I have just now realised that the ATL-1000 doesn't have a C41 2 bath programme, but I figure I can just use the regular one, whilst pouring water in the third bath container.

However, I ran the whole C41 process through, without any problems - I mean, the machine didn't beep or something. Now I figured something went wrong, because during the pour out, no solution was poured out at all. After the programme finished, I opened the tank, just to realise that none of the baths were actually POURED IN!!! and indeed it stayed in the containers. I have launched the cleaning programme, and now pouring in and out worked without a glitch...

anybody has any idea what the problem could be? I am currently rerunning the C41 process, but with water instead of the solution, just to figure if it could be a problem of the programme selected...

thanks for all your help,

Did you forget to close the lids on the chemical bottles? If they are left open, the chemical will not pump into the film tank. Run a simulated process suing water in the tanks: at each processing step listen for the whining pump noise and try to figure out if the pump is working. Troubleshooting is time-consuming and annoying.

I second this suggestion as I have it happen to me once. :o

Roger,
Would the D250 still have the same problem with the initial cold water from an instant gas hot water service..i.e. as has been mentioned below that it take perhaps half a minute before hot/tempered water to comes through, its cold until then. Or does the d250 not let the water through until it is at correct temp?

Using the second valve opening; I am wondering if it adversely affects the flow rate to the Jobo tanks, just a test it situation until you get it right I suppose. While the valve is open to the Jobo half flow rate to the machine and half down the drain, while the valve is closed to the Jobo (between washes) twice the flow down the drain?

I used a shower valve setup on the shower side of the valve (up) I placed a thermometer from a temp control valve, got it though Calumet. Was fairly accurate, E6 i did in the sink looked very good (never put it on a densitometer though).
