206. An air-cooled refrigerated container unit using R-134a as a refrigerant has a box temperature set point of 32°F, but it is currently operating with a stable supply air temperature of 35°F. The fresh air makeup vent is closed, the unit is operating at 460 VAC/60 Hz, and the unit is in full capacity cool (modulating valve 100% open). Using the illustrated troubleshooting guide, what would be the normal range of expected discharge pressures if the ambient air temperature is 90°F
