Prep / process for sending AP to Clearwater?

[Speed]

Hi All

In a prior thread I was advised my 15300 is going to need to go in for repair.

I plan to call AP Monday, but can someone give me the rundown of how to prep my AP for sending off to Service?

Packaging / mailing method / etc.

I am spoiled being near a RSC so I simply drop off there.

Thanks!
