Question:
Could somebody tell me where I can find description of air conditioner
installation.
I've already mounted split system air conditoner myself, but I'm a little
confused about pipping.
The information I'm searching is how to prevent air from getting into indoor
unit when I connect pipes.
Only solution I can think of is to fold the copper tubes and after
connecting unfolding these tubes, but I'm concerned
about tube damaging.
I need some advice or place on net where I can find that information.
Answer:
You MUST get a PRO to install your A/C
SYSTEM!
Unless you use special quick connect tubing (connection system, -you
don't) there will always be air in the refrigerant lines before
connecting them. I used to add a suction line filter dryer and and one
on the liquid line if the condenser didn't have one. The copper lines
need a low flow of nitrogen through them while brazing the connections.
Then you can pressurize with nitrogen to NO more than 250-PISG and test
for leaks. No leaks purge the lines of and evacuate the lines to
400-microns. These practices will sufficiently eliminate the moisture
and air in the refrigerant lines.
