Re: Evacuating refrigerator compressor

Top-O-the-Day:
If your refrigeration tech doesn't have a vacuum gauge that is measuring in microns....find another refrigeration tech.

Tip No 2.
If after vacuuming down your system for 30 minutes the tech tells you, "that's good boss, now lets recharge"...find another refrigeration tech.

And as a Bonus:
If your refrigeration tech doesn't know the difference between how to charge a Capillary Tube vs TXV system, yep you guessed it....find another refrigeration tech.

Great advice Rich, simple and to the point but may I add..

Tip No 4. If the refrigeration tech / adviser spends the first 30 minutes (His short version!) telling you how great he is and who he talked with thirty years ago about yada yada ya etc..... find another tech / adviser!

On a serious note, if an R134a compressor is suspected of being contaminated, change the oil, its the best solution.. Also always fit a PROPER filter dryer. Not a spun copper type which have no felt filter, but a Sporlan type 032 or better still a 052 FILTER dryer. Then evacuate over night with a 2 stage pump (with digital vaccustat if possible)
