Hold the capacitor in place with one hand. Affix the metal strap bracket around the capacitor with the other hand. Screw the metal strap bracket down over the capacitor on both sides.
Connect the FAN, COM and HERM wires to the top of the capacitor. If your capacitor does not come labeled for wiring, check the wiring diagram in your air conditioning manual to ensure that you connect each wire in the correct slot.
Close the condenser's electrical access panel. Screw the unit lid closed.
Turn on the circuit breakers. Turn the thermostat's temperature lower than the current temperature. This turns on the air conditioning system and the new capacitor.
