Need help installing a new a/c system
Hi . I have too install a new A/C system and between the outdoor unit and the building it's a side walk and I have to go with the piping (7/8 inch) underground for 6 feet .`
My question is if I have too put a trap for the oil ? I am 95% sure that I have too , but it's better to have others opinion too .
Thanks

You don't need to put trap. Speed and density of refrigerant is enough to return oil, and inverters have function to recover oil in prolonged operation on low revolutions.

Check the manufacturers installation manual. On some units you have trap every 10m if the outdoor unit is below the indoor as your diagram shows.

Always follow the installation manual, always.
As you haven't said what kit you are installing, nobody will be able to give you the "right" advice but the install manual that comes with the kit will always be right.
