If the suction pressure, discharge pressure, and suction superheat degree are not
within the normal ranges, check the following items:
1. Refrigerant has been charged as required. If the refrigerant is
overlled, the
discharge pressure is high. If the refrigerant is underlled, the discharge and
suction 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 5 After charging refrigerant, close all valves.
Step 6 On the home screen, choose Maint > Diagnostic Mode > Exit and
conrm the
operation.
Step 7 Tap Shutdown on the home screen.

● Wizard Startup allows you to commission the indoor and outdoor fans, electric
heater,
humidier, condensate pump, and cooling system, and supports
automatic running and judgment of components.
● After you power on the smart cooling product for the
rst time, the Wizard
Startup screen is displayed. If the smart cooling product is not started for the
rst time, choose Maint > Wizard Startup to enter the Wizard Startup screen.
● Tapping No or Exit, a submission timeout, and a system exception all result in
commissioning failures. Choose Maint > Wizard Startup to enter the Wizard
Startup screen and start the commissioning again.
