I emailed Jobo about this weeks ago, but no response yet (other than an immediate "auto-reply" saying they got the question).
indicates that recent CPA/CPP processors have the same rotation motor as ATLs. The instruction manual for ATLs specifies a maximum of 1.5 liter can be used in Expert Drums. Manual processor instructions limit chemistry to 1 liter in Expert Drums.
Since the CPA/CPP manual appears out of date with respect to rotation speeds (see this thread)
I wondered if it is also obsolete concerning ability to rotate larger quantities of chemistry. I asked Jobo whether it would be safe to use 1.5 liter with my post-22000 serial number CPA-2 and an Expert drum, or was there some limiting mechanical factor other than the stronger motor. I noted that I always "help" the lift by supporting most of the drum's weight from below when emptying it.
In the absence of a response from Jobo, has anyone with a newer CPA/CPP-2 used it this way, and have you experienced reliability impacts? Thanks in advance.
