Page 3: Safety Precautions
Safety precautions The safety information and precautions below must be kept for the safety of users and installers. Before installing an air conditioner, please read this manual thoroughly to ensure that you know how to safely and efficiently install a new appliance. DVM S air conditioner uses R-410A refrigerant. - Page 4 Safety precautions FOR INSTALLATION WARNING Make sure to connect wires thoroughly and fix them firmly so that no outer pressure of the wires would put on the terminal block. If the terminal is loose, it may generate heat and cause a fire. Supplied power should be more or less than 2% of the rated power.
