Using this Westinghouse motor capacitor is a breeze. First, make sure your appliance is turned off and unplugged. Then, find the old capacitor in your appliance and carefully remove it by detaching the wires from the terminals. Next, connect the wires of the new capacitor to the corresponding terminals on your appliance. The 4.8mm female spade terminals make this connection easy. After that, use the square mounting clip to secure the capacitor in place. When handling the capacitor, be gentle to avoid any damage. As for maintenance, there's not much to do. Just keep it clean and dry. If you notice any signs of damage like cracks or bulges, replace it right away. And always follow the safety instructions of your appliance when working with electrical components.
