If it's much different than that, then you would want to treat it as contaminated refrigerant when recovering. I assume 5 below would mean 80º in this example to account for the indoor coil being colder, so 236 psi.The liquid pressure should be 385-395 and the suction pressure should be about 138 but will probably be a few psi lower since it's so cool in the space. The sub-cool should be 11 deg. F +/- 1.5 deg. F.
