Question about LG LW5200ER Air Conditioner
Depending on your indoor and outdoor air temp is, a cooling system will condition the air by 15-20°f. So if it is pulling in 80°f air, it should be supplying 60-65°f. The amount of gas cannot be answered here, without more info. That answer should be on the name plate/tag on the unit, "R410-A = 32oz." Or something like that.

SOURCE: regarding gas pressure
ok lets see how i can help you. If the units low on gas, suspect a refrigerant leak!! 2nd, what refrigerant it's using? I can't tell you operating pressures if you don't know the refrigerant. (usually the label on the indoor unit right side says refrigerant charge and type.) 3rd desired temperature for cooling is about 68-72 F that's about 20-22 Celsius.
id keep it on 21 C

SOURCE: recharge gas
The pressures are based on ambient temperature outdoors and temps indoors. Also, it is based on the seer rating for this unit. You have to use a chart so you can do the calculations. Unless you have this chart, you can't charge they system. I would not recommend doing it yourself. Have a professional do this as it can be very dangerous for the inexperienced.

Sorry to sat but the tech has no idea what he is doing. The metering device is in the discharge valve, making that line a low pressure, not high. If the "suction" line is hotthen it is running in heat mode.

I think the more likely problem is that the unit is slightly short of gas\ refrigerant, which is a common cause of icing up evaporator coils and this sound you describe. First check that the air filter is clean. Another cause could be the defrost sensor is faulty, but I would think not. Some ice isn't actually a bad thing, but quite common as long as it doesn't form over too much of the coil, or get too thick.

the fact that it is not draining could be the problem with it freezing up. you might have to pull it out of the window, pop the cover off and clean the drain pan so it will drain properly. also make sure the unit is level . if it still freezes up once draining properly it is probably low on charge.
