R407C to R404a

[MaDiNfO]

i've buyed a A/c unit and the manufacture says that i've need to fill it with 560grams of R407C is it possible to put instead R404a ?

wath should be the working pressure of the R407C in the suction line ? (psi)

and if i use 404 ?

tanks in advance

[NoNickName]

No, you can't. R404a has a higher oil dilution and carry over, and higher condensing pressure.

and only for 2 or 3 days ? wath should be the presure on the gaugs for the original gas ?

[NoNickName]

No, you can't even for three minutes.

Capillary is also calculated for r407c.
Like NoNickName said, no, you can't.

But I should give it a try if I was you, and post here how long your compressor ran.

Sorry I have to say, but I read many of your posts of the last 24 hours - there were a lot of it - and I bet you'r not a HVAC/R tech at all.
You bought an AC somewhere - perhaps on Ebay - not willing to pay the proper price to a qualified tech.

who said that i was one ?

Don't worry, no one has accused you of being competant.

Be careful you don't let the smoke out of the compressor. They work on smoke and they never work again once the smoke comes out.

Didn't you know thats how electronics work as well? The majic blue smoke, once it escaps from the CPu it never works again, so you have to be care full not to let the smoke out!
