how long can a drier be exposed to the atmosphere? situation is we replaced the condenser and drier on a 2002 saturn l200 due to front end damage. a week later we took it to a dealer for a charge and they discovered a broken hose at the compressor. hence the drier has been exposed to the atmosphere for about week, will vacuuming the system take out the moisture in the drier? we removed the compressor, there was about a ounce of very clean oil left in it. we purged new oil thru the compressor and all seems fine. the system calls for 7.50 oz of pag 100 oil. assuming 1/2 oz of oil left in compressor, and 2 oz of oil left in the rest of the system (evaporator lines etc) we plan to add 5 oz of oil. 2.5 oz in the suction side of the compressor and 2.5 oz in the discharge line coming from the compressor. does this sound correct? thanks for the input in advance. thanks again
Depending on how humid it was a good evacuation with a good dual stage vacuum pump should remove any excess moisture in this case.
hummm.......i just ordered a 3cfm 75 micron pump from ackits. this is a single stage pump, might i ask what a 2 stage pump does over the single stage. i called ackits and they recommended this pump based on my future usage and applications. did they steer me wrong? thanks again for the input.
Dual stage pump will just pull a vacuum quicker and for large applications may pull a deeper vacuum. I do not believe my staff would ever intentionally mislead our customers! If I were doing general a/c at home. I would have no issue using the 3cfm single stage pump or any Mastercool pump we offer. But I would not try and use the 1.5 CFM pump to pull down a 3 unit Bus system!
the sales person i talked with was extremely courteous and knowledgeable about the products. i had the upmost confidence in his recommendations. hence why i purchased gages and a pump. i could have bought for a lessor price elsewhere but the support of this forum and the sales persons advice was well worth the price difference along with the fact that i hope the quality of the gages and pump is better. thanks again for the reply i do feel better this pump will work for the present application.
Mastercool makes a very good product and I think you will be happy you choose that route. Thanks for supporting us and the forum. It is only with sales that we can keep this forum running in the long run.
