    I had one like that. Took 60LBS out of a 20lb sack. LLFD was clogged and so was the inlet txv screens.

    Yeah, the store owner was pissed as he paid for all that refrigerant that was pumped in by a previous company. And then he didn't want to pay me after i fixed it. He thought a couple ice creams out of the case would be suffecIent payment!

    No!!! I can't remeber exactly. But, i do know it's pretty much a now obsoleted blend. Even back then it was too!! Mp66 maybe? I started a thread here when i was working on this system. But, i can't find it anymore. Maybe, the archives do not go back that far.

    Right on. I wasn't aware of this. the temperature at the inlet and the out let of this filter dryer is the same. what a bummer.

    Thanks for the advice.
