The guys on site have installed a Daikin vrv 2 pipe replacement technology system.
Went to pressure test the weekend and wasn't getting a reading back on suction side!
Checked gauges ,lines and valves.
Checked flare nuts on fcu along system to see if nitrogen was present(ALL OK)
I am wondering if the indoor units have solinoid valves in fcu and if power was applied to indoor unit or units they would close ?
Any help would be appreciated.
Regards
