There are many things to consider when determining the volume requirements for processing.
The 'Minimum Volume' stated in the charts below is just the amount of solution that is required to physically cover the film or paper with a level of solution. Never run a process with less than this volume of solutions. Partially unprocessed film or prints will result when using too low a volume.
These volumes are for rotary processing only.
If these tanks or drums are used in any other fashion, such as inversion (hand) techniques, or any procedure that does not have constant agitation, more volume will be required.
These minimums require accuracy.
Accurately measure your volumes. The tank or drum has to be completely level. If the tank or drum end facing away from the magnet or lift coupling is floating above the rollers, the higher end will not be sufficiently covered in solutions. Adjust the level of the water bath until the end no longer floats.
Place a level on the tank or drum. Adjust the leveling of the processor, if necessary.
The 'Minimum Volume' is not necessarily the volume you need to use for processing.
Consider the requirements of your specific chemicals, in combination with the specific film or paper being processed. Note extended dilution (if used). Be sure that the volume required for the square footage (or meters) is sufficient to properly process the amount of film or paper in your tank or drum.
If you are unsure of these requirements, check with the chemical or film manufacturer for their specifications. In all cases, if this volume required for the amount of film or paper is higher than the 'Minimum Volume', use the chemical manufacturer's requirements as your "minimum".
Always compare these two figures and use the higher one as your "minimum."
When in doubt, use a higher volume of solutions.
The 'Minimum Volume' is just that, a minimum. Using more than a minimum amount will not harm virtually any process. Extra volume of chemicals will not "over develop" your film or paper. (Note, however, the precautions in the next section regarding processor limits.)
If your film or paper is coming out "underdeveloped" it could be caused from too little volume of chemicals. If this is the case, extending the development time will not completely cure the "underdevelopment." Increase the volume of chemicals used. An excess volume of chemicals will not "over develop" your film or paper.
Never use a tank or drum loading that exceeds the processor's specifications.
Do not use any combination of chemicals, tanks, reels, drum, and amount of film or paper, that is going to require more volume of solutions than the maximum recommended volume stated for your processor. Doing so will shorten the life of the processor's rotation motor and other components.
When using extended dilutions of the developer, you may need to limit the number of films put in some of the larger tanks or Expert Drums. This prevents the resultant volume of solution from being more than the recommended maximum safe capacity of the processor.
See the 'Footnotes' for specific warnings about over capacity.

- The CPE-2 and CPE-2 Plus should not be used with more than 600 ml of solution. Excess volumes will limit the useful life of the rotation motor.
- The CPA-2 and CPP-2 processors should not be used with more than 1000 ml of solution. Excess volumes will limit the useful life of the rotation motor. The ATL's 1, 2, 2 Plus and 2000 cannot be used with more than 1000 ml of solution.
- The ATL's 3 and 3000 cannot be used with more than 1500 ml of solution.
- This tank or drum requires a Cog #1505 to be installed before using it on a JOBO Lift or an ATL processor, or a Magnet #1504 for use with a magnet drive processor.
- This tank or drum is too large to fit the CPE-2 or CPE-2 Plus processors.
- All Modules must be used with a tank or drum. They cannot be used alone.
