Vacuum Operation
ـ Operation to facilitate vacuum to open the valve after the Outdoor Unit repair.
غ
Piping Inspection Operation
ـ Operation mode to check the status of the piping between the MCU and the indoor unit.
ـ Heat Pump Model : Outdoor temperature is more than 15°C / Cooling commissioning start
Outdoor temperature is less than 15°C / Heating commissioning start
غ
Discharge Mode Operation
ـ Outdoor power is turned off, the Inverter PCB and Fan PCB charging a high DC voltage, so dangerous to touch.

- In particular, E 464, E364, power devices may be damaged, therefore do not use the discharge mode.
ـ Block the Inverter PCB 3-phase relay after connected the power, and through compressor, DC voltage is discharging.
- INV1 and INV2 DC voltage during discharge mode are displayed alternately.
