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.)
On the diagnostic mode screen, change the compressor input to 0 rpm.
Exit the diagnostic mode.
