Friedrich Ductless Unit Install

EASports · 07-07-12, 10:30 AM

I have the unit mounted high pressure and suction lines run and flared.
This unit uses r410a freon, when I try to connect my gauges to the outdoor unit, they will not fit. The fittings on the unit are not the same as my other units on the house.
The suction side does not even have a schrader valve.
What connector do I need to pull vacuum on this unit? Should I add a scrhader to this unit?

Get an adapter from a refrig. supply store... around $7.
