The bryant web site has no info. Init not cooling well and freezing top and bottom of evap.
This is an R410a unit with a speed controler that controls the compressor and the condenser fan.
OAT 75 degrees F
Suction 88.1 PSI @ 707 degrees F
Liquid line going into evap at service port 280.6 PSI @ 91.4
It has been awhile since I had to use a charging chart so I am rusty but it looks like the suction pressure should be closer to 130 PSI. Based on my experience with 410a that sounds right. 280 sounds low on the high side to me but since it has variable speed on the condenser fan and compressor I don't know what effect that would have on the pressures and temps.
