Using this 450Volt 6.3uF motor start capacitor is quite straightforward. First, make sure your appliance is unplugged. Then, find the old capacitor and carefully remove it. Connect the new capacitor in the same way as the old one, using the 3/8' bolt and nut on the base for mounting. When handling the capacitor, avoid touching the metal parts directly. Also, don't try to use it in appliances with different voltage or capacitance requirements. To keep it in good condition, keep it in a dry and cool place. If you notice any signs of damage, like swelling or leakage, replace it right away. And if you have any doubts during installation, feel free to consult a professional.
