Context
The startup wizard allows for commissioning of components such as the indoor fan, spray
system, exhaust fan, and cooling system. It also supports component automatic operation and
automatic device checking, and can output commissioning report.
After you power on the smart cooling product for the first time, the screen displays the
Wizard Startup screen. If the smart cooling product is not started for the first time, choose
Maint > Wizard Startup to enter the Wizard Startup screen.
Tapping No or Exit, submission timeout, and system exception all result in commissioning
failures. Choose Maint > Wizard Startup to enter the Wizard Startup screen for new
commissioning.

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.)
