Parker DSP360 - is there a manual somewhere I can download?

Is there a manual I can download for the Parker DSP360 Spool Gun?
I have one and I'm about to start using it for aluminum work with my 230i.
Can't seem to locate a user manual for it on the everlast website.

Also, is there a difference between the DSP360 and DSP360A ?

Thanks in advance for the assistance.

No manual. They set up basically like all spool guns. Simple, straight forward.
