Instruction Manual

1. Introduction

This manual provides essential information for the safe and effective use of the UpStart Components 80/5 MFD 370 Volt Dual Round Run Capacitor. This component is designed as a direct replacement for Rheem/Ruud RAMB-060JAZ and similar applications requiring an 80/5 MFD 370 Volt dual run capacitor. Please read this manual thoroughly before installation or maintenance.

2. Safety Information

WARNING: Risk of Electric Shock and Injury!

• Always disconnect power to the equipment before attempting any installation, removal, or maintenance of the capacitor.
• Capacitors can store a dangerous electrical charge even after power is disconnected. Always discharge the capacitor safely before handling. Consult a qualified technician if you are unsure how to do this.
• Wear appropriate personal protective equipment (PPE), including insulated gloves and safety glasses.
• Installation should only be performed by a qualified and licensed HVAC technician or electrician. Improper installation can lead to serious injury, property damage, or equipment failure.
• Ensure the replacement capacitor's voltage rating is equal to or higher than the original. The microfarad (MFD/uF) rating must match the original exactly.

3. Product Features

• Replacement Dual Round Run Capacitor for Rheem / Ruud RAMB-060JAZ; 80 / 5 MFD 370 Volt.
• Designed for use in a wide variety of applications to maintain optimum performance.
• Essential component for starting and running electric motors in HVAC systems.
• Constructed with durable materials for reliable operation.

4. Setup and Installation

Note: Installation should only be performed by a qualified professional.

1. Power Disconnection: Turn off all power to the HVAC unit at the circuit breaker or disconnect switch. Verify power is off using a voltage meter.
2. Access Capacitor: Locate and open the access panel to the capacitor compartment.
3. Discharge Capacitor: Safely discharge the old capacitor using a properly insulated screwdriver with an insulated handle by shorting the terminals. Wait at least 5 minutes for any residual charge to dissipate.
4. Note Wiring: Take a clear photo or draw a diagram of the existing wiring connections to the capacitor terminals (Herm, Fan, Common).
5. Remove Old Capacitor: Disconnect the wires and carefully remove the old capacitor from its mounting bracket.
6. Install New Capacitor: Place the new UpStart Components capacitor into the mounting bracket.
7. Connect Wiring: Reconnect the wires to the corresponding terminals on the new capacitor according to your diagram. Ensure connections are secure.
8. Secure and Restore Power: Close the access panel. Restore power to the unit and test its operation.

5. Operating Principles

A dual run capacitor, like the UpStart Components 80/5 MFD 370 Volt model, is a critical electrical component in many HVAC (Heating, Ventilation, and Air Conditioning) systems. It serves two primary functions:

• Start Function: It provides a temporary boost of electricity to the compressor and fan motor to help them overcome initial inertia and start rotating.
• Run Function: Once the motors are running, the capacitor continues to provide a phase shift to the motor windings, improving efficiency and ensuring smooth, continuous operation.

The "80/5 MFD" rating indicates two separate capacitance values within one unit: 80 microfarads (MFD) for the compressor (Herm) and 5 microfarads (MFD) for the fan motor. The "370 Volt" rating specifies the maximum voltage the capacitor can safely handle.

6. Maintenance

Capacitors are wear-and-tear components and will eventually degrade. Regular inspection can help identify issues before they lead to system failure. Replace your capacitor if you observe any of the following:

• Bulging Top: The top of the capacitor appears swollen or domed. This is a clear sign of internal failure.
• Leaking: Any signs of oil or residue leaking from the capacitor casing.
• No Continuity: When tested with a multimeter, the capacitor shows no continuity across its terminals, indicating an open circuit.
• Reduced Capacitance: A professional test reveals the capacitance (MFD/uF) has significantly dropped below its rated value.

It is recommended to have your HVAC system, including the capacitor, inspected annually by a qualified technician.

7. Troubleshooting

If your HVAC system is experiencing issues, a failing capacitor could be the cause. Common symptoms include:

• Outdoor Unit Not Starting: The fan or compressor in the outdoor unit does not start, but you might hear a humming sound from the unit.
• Fan Not Spinning: The outdoor fan motor is not spinning, even though the compressor might be running (or vice versa).
• System Blowing Warm Air: The compressor is not engaging, leading to the system only circulating air without cooling.
• Tripping Breaker: While less common for a failing capacitor, a shorted capacitor can cause the circuit breaker to trip.

If you suspect a capacitor issue, always consult a qualified HVAC technician for diagnosis and replacement. Do not attempt to troubleshoot or repair electrical components without proper training and safety equipment.
