Have you checked out Kodak Z-119? It is located in here:

You will see that you will need tempered wash between the first and color developer steps. The wash water needs to be 38 +/- 1.0 degree C. This is the difficult part for your ATL-2300. I have not figured out how to economically achieve this for my ATL-2300. I have considered to install a smallest electrical water heater available from Home Depot for about $150. I have hesitated for quite a while. I know such a water heater will do the job quite well if I want 50 - 75 degree C water. But I am not sure if it can be set to 38 degree C. I am not sure if the temperature of the water will be stable even within +/- 5 degree C when the process is started.
