Lippert Hydraulic Purge - How To Do It?

2005 MS 5er - Symptom: "Off Door" slide drifts out when raising front of 5er. Also, "Rear level" stands raises when moving "bedroom" slide. Lippert says I have dirt in my fluid that is keeping valves cracked open and I need to purge the system. Lippert says they have "How To Document" they can send to a RV Service Center. Does anyone have a copy of a "How To Document" or can describe the step by step process? (I searched the forum with no results) I want to understand the process before I find and book the Service. (Maybe even do it myself)

    The link provided the air purge .pdf document which is great. Thanks! Since I am also trying to remove the contaminated fluid (containing dirt/particles that may be keeping the control pistons opened), I need a "how to" document to completely remove the existing fluid, flush and then refill the system. During the process I will also dismantle and clean the control valves, check o-rings and springs, reassemble and then fill and perform the purge process on the system to remove any air. Any feedback on a process to remove and flush the old fluid? Thanks again!
