If the suction pressure, discharge pressure, and suction overheating degree is without normal
ranges, check and make sure that:
1. Charge refrigerant in an amount exactly as standard charge required. (Refrigerant charging
too much would result in high discharge pressure. Refrigerant charging too little would result
in low suction pressure, low discharge pressure, and high suction overheating degree.)
2. The air inlet and outlet of outdoor unit are without block. (The air inlet and outlet blockage
would result in high discharge pressure.)
Step 5 After charging refrigerant, close all valves.
Step 6 Tap
Step 7 Tap Shutdown on the home screen and confirm it.
