Simon - Thank you for the question. To engage PCC mode, you'll need to create a custom program. To create a custom program, use the ‘< P >’ buttons on the lower right of the screen to toggle between programs P1 through P20. You can create up to 20 custom programs on this unit. The create a custom program with PCC mode, you'll need to set your microamp setting at 10 or below. Let us know if you have any more questions, and we’ll be happy to help.

Great question! You can find the step-by-step instructions to change your OptiFlex Pro’s application on page 33-34 of the corresponding manual found here: www.gemapowdercoating.com/fileadmin/documents/User_Manuals/English/Equipment_and_Controls/Gun_Controls/OptiStar-CG21-en.pdf?hash=1715870895 Basically, after moving the powder pump from the box feeder to the top of your hopper, you’ll hold the lower left button on the controls screen for 5 seconds until the screen changes to display the P00 system parameters. Next, you’ll toggle the application to ‘0’ / ‘F’ for fluidized hopper. Hope this helps!
