    12. TROUBLESHOOTING WARNING!!! When Power Up – the whole outdoor unit controller, including the wiring, is under HIGH VOLTAGE!!! Never open the Outdoor unit before turning off the Power!!! When turned off, the system is still charged (400V)!!! It takes about 3 Min. to discharge the system. Touching the controller before discharging may cause an electrical shock!!! For safe handling of the controller please refer to section 1.6 below.
