High quality time saver

Installed on a Gree Flexx 36k

This line set is a bit expensive but very well made. It does come with the adapters needed to connect to standard flare fittings but no thread lubricant is supplied. I recommend Nylog.

Other than the inherent difficulty of bending 3/4" copper pipe, it was a breeze to install. Product is 10/10 but I can see where a premade line set would not be appropriate for a lot of installs and the length calculation is absolutely critical.

Both lines come individually insulated and the insulation is high quality. I did not need the liquid line insulation for my application so it was been removed.

What size clearance is needed to run the line set through the wall

Premium Home Source

Hi,

To run the MRCOOL No-Vac line set through a wall, you’ll need a hole clearance of approximately 3 to 3.5 inches in diameter. This allows enough room for both the 3/8" liquid line, 3/4" suction line, insulation, and quick connect fittings to pass through without damage.

Be sure to seal around the opening after installation to prevent air or moisture infiltration.

Hope this helps!
