Charge refrigerant on the basis of the precharging.
Step 5 On the home screen, choose Running > Device Details > Compressor, and view
Suction pressure and Discharge pressure to determine whether they are within
normal ranges. Choose Running > Device Details > EEV and view EEV suction
superheat degree to determine whether it is within the normal range.

If the suction pressure, discharge pressure, and suction superheat degree are not within the
normal range, check the following items:
1. Refrigerant is charged to the standard amount. (If the refrigerant is overfilled, the discharge
pressure will be high. If the refrigerant is underfilled, the suction and discharge pressures will
be low, and the suction superheat degree will be high.)
2. The air intake vent and air exhaust vent of the outdoor unit are not blocked. (If the air
intake vent and air exhaust vent are blocked, the discharge pressure will be high.)
Step 6 After charging refrigerant, close all valves.
