General safety precautions ▪ Charge the refrigerant in liquid form. Adding it in gas form may prevent normal operation. CAUTION When the refrigerant charging procedure is done or when pausing, close the valve of the refrigerant tank immediately. If the valve is NOT closed immediately, remaining pressure might charge additional refrigerant. - Page 11 General safety precautions CAUTION ▪ When connecting the power supply: connect the earth cable first, before making the current-carrying connections. ▪ When disconnecting the power supply: disconnect the current-carrying cables first, before separating the earth connection. ▪ The length of the conductors between the power supply stress relief and the terminal block itself MUST be as such that the current-carrying wires are tautened before the earth wire is in case the power supply is pulled loose from the stress relief.
