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. Charge refrigerant in an amount exactly as standard charge required. (If the refrigerant is
overfilled, the discharge pressure is high. If the refrigerant is underfilled, the suction and
discharge pressures are low, and the suction superheat degree is high.)
2. The air intake and exhaust vents 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.
Step 7 Tap
to exit the diagnostic mode.
Step 8 Tap Shutdown on the home screen and confirm it.

6.8 Wizard Startup
Prerequisites
Check that refrigerant is fully charged before performing the wizard startup.
Context
The startup wizard allows for commissioning of components such as the indoor
fan, electric heater, humidifier, condensate pump, and cooling system. It also
supports component automatic operation and automatic device checking.
