I'm building a new darkroom next summer and as I got an odd chance to purchase a second-hand Agfa Pro processing machine for RA-4, I thought to ask if there's anything very important to know about operating this type of machine. I have no prior experience with processing machines. How much will the estimated water consumption be, for example, with these machines? Is there something else that I need to take into account when planning the arrangement of the facilities in the darkroom? Extra ventilation, etc? It will be a single room of approx 10x8 feet, used for enlarging and developing mainly BW prints on RC paper. Also for developing films (35mm and 120) and maybe also drying them. Prints will be viewed and dried in a separate room (a smaller room or porch with natural light). My enlarger is a Durst AC800 that takes some 2x2 feet of tablespace. Additionally there will be a small sink and a glass-top table for the wet side work.
