1. Introduction
This manual provides essential information for the safe and effective use of your BOJACK CBB65 130uF 250V Round Run Start Capacitor. This capacitor is designed for the start-up and continuous operation of AC motors with a frequency of 50Hz/60Hz. It is commonly used in applications such as central air conditioners, heat pumps, condenser fan motors, and compressors. Please read this manual thoroughly before installation and operation.
2. Safety Information
WARNING: Electrical components can cause serious injury or death. Installation and servicing should only be performed by qualified personnel. Always disconnect power before working with electrical systems.
- Power Disconnection: Ensure all power to the appliance is disconnected at the circuit breaker or fuse box before attempting any installation or maintenance.
- Capacitor Discharge: Capacitors can store a dangerous electrical charge even after power is disconnected. Always discharge the capacitor using a properly insulated screwdriver or resistor before handling. Touch the metal shaft of a screwdriver across the capacitor terminals to discharge it.
- Proper Handling: Avoid touching the terminals of the capacitor with bare hands. Use insulated tools.
- Correct Rating: Always replace a capacitor with one of the same microfarad (uF/MFD) and voltage (VAC) ratings. Using an incorrect rating can damage the motor or capacitor and pose a safety hazard.
- Environmental Conditions: Do not expose the capacitor to moisture or extreme temperatures outside its specified operating range.

- Application: Suitable for compressor motors and fan motors in central air conditioners, heat pumps, and other AC motor applications.
4. Setup and Installation
This capacitor is a replacement component and requires careful installation. It is strongly recommended that installation be performed by a qualified HVAC technician or electrician.
- Disconnect Power: Turn off all power to the appliance at the main circuit breaker or fuse box. Verify power is off using a voltage tester.
- Locate Old Capacitor: Open the access panel of the unit (e.g., air conditioner outdoor unit) and locate the existing capacitor.
- Discharge Old Capacitor: Carefully discharge the old capacitor using an insulated screwdriver. Place the metal shaft of the screwdriver across the terminals. A spark may occur. Repeat for all terminals.
- Note Wiring: Take a clear photograph or draw a diagram of the wiring connections to the old capacitor. Note which wires connect to which terminals (e.g., Herm, Fan, C).
- Remove Old Capacitor: Disconnect the wires from the old capacitor and remove it from its mounting bracket.
- Install New Capacitor: Place the new BOJACK CBB65 capacitor into the mounting bracket.
- Connect Wiring: Connect the wires to the new capacitor's terminals exactly as they were connected to the old one, referring to your photograph or diagram. Ensure connections are secure.
- Secure Access Panel: Close and secure the access panel.
- Restore Power: Restore power to the appliance at the circuit breaker.
- Test Operation: Test the appliance to ensure it is functioning correctly.

5. Operating Instructions
The BOJACK CBB65 capacitor operates automatically once installed correctly within an AC motor circuit. Its primary functions are:
- Motor Start-up: Provides the initial electrical boost required to start the motor, overcoming inertia.
- Motor Run: Helps maintain a consistent phase shift in the motor windings, ensuring efficient and continuous operation once the motor is running.
No user interaction is required for the capacitor's operation after proper installation. The capacitor is designed for continuous duty within its specified operating parameters.
6. Maintenance
Capacitors are generally maintenance-free components. However, periodic inspection can help identify potential issues before they lead to failure.
- Visual Inspection: During routine appliance maintenance (e.g., annual HVAC service), visually inspect the capacitor for signs of swelling, leaks, or corrosion. A bulging top or bottom indicates internal failure and requires immediate replacement.
- Cleaning: Ensure the capacitor and its terminals are free from dust, dirt, and debris. Use a dry cloth or brush for cleaning.
- Connection Check: Verify that all wire connections to the capacitor terminals are secure and free from corrosion.
Always disconnect power and discharge the capacitor before performing any inspection or cleaning.
7. Troubleshooting
If your appliance (e.g., air conditioner, compressor) is experiencing issues related to motor start-up or operation, a faulty capacitor may be the cause. Common symptoms include:
- Motor Hums but Doesn't Start: This is a classic symptom of a failed start or run capacitor. The motor receives power but lacks the necessary phase shift to begin rotation.
- Motor Starts Slowly or Intermittently: A weak capacitor may not provide sufficient power for a quick, consistent start.
- Reduced Efficiency or Overheating: A failing run capacitor can cause the motor to draw excessive current, leading to reduced efficiency and overheating.
- Clicking Sounds: Some units may have a relay that clicks repeatedly if the motor attempts to start but fails due to a bad capacitor.
Troubleshooting Steps:
- Safety First: Disconnect all power to the appliance and discharge the capacitor as described in the Safety Information section.
- Visual Inspection: Check the capacitor for any visible signs of damage (bulging, leaks, burns).
- Test with Multimeter: A qualified technician can test the capacitor's capacitance (uF) using a multimeter with a capacitance function. Compare the reading to the rated capacitance on the capacitor label. A reading significantly lower than the rated value indicates a faulty capacitor.
- Professional Assistance: If you are unsure about testing or replacement, contact a qualified technician.
