Hi, Thanks so much 4 replying reefer mechanic, phil Landon.
I've checked this unit in this morning, problem i think that's WATER inside, have amount of water inside reefer container, maybe water pipe's choed up & 4 drains hose can't open. So the time to pretrip is long. Tommorow, my coworker will clean inside then try to PTI it again, then i'll report to u.

@ phil Landon, i'll pay attention to ur ideas. Thanks

Thanks again 4 reply,
Goodluck all.
