Hi guys iv got a fdc335kxe6r that has 8 evap units on it,168 meter pipe run and shows on the trim charge it’s had about 18.3kg added and total charge is 30.3kg. When all indoor units are turned on and are running it works fine,when all indoors are put into test cooling it drops down on the suction to around 10psi and cuts out,no faults show on any of the controllers. Could this be possible it’s been miscalculated on trim charge,it works fine on standard running but as soon as all indoors go in test cooling it lasts about 5 mins then just drops out and all controllers turn off. Any help appreciated
