- Refrigerant recovery machine
- Vacuum pump
- Manifold gauge set
- Torque wrench
- Electrical tester
- Safety glasses
- Gloves
Safety Precautions
- Always disconnect the power supply before working on any electrical components.
- Wear gloves and safety glasses when handling refrigerant.
- Follow all manufacturer’s instructions carefully.
- If you are not comfortable performing any of these steps, consult a qualified HVAC technician.
Step 1: Recover the Refrigerant
- Connect the refrigerant recovery machine to the low-pressure service port on the outdoor unit.
- Turn on the recovery machine and allow it to extract the refrigerant from the system.
- Once the refrigerant has been recovered, close the service port.
Step 2: Remove the Outdoor Unit
- Disconnect the electrical wires from the outdoor unit.
- Remove the refrigerant lines from the outdoor unit.
- Carefully lift the outdoor unit and place it in a secure location.
Step 3: Install the New Outdoor Unit
- Position the new outdoor unit in the desired location.
- Connect the refrigerant lines to the outdoor unit.
- Connect the electrical wires to the outdoor unit.
Step 4: Install the Indoor Unit
- Mount the indoor unit on the wall or ceiling.
- Connect the refrigerant lines to the indoor unit.
- Connect the electrical wires to the indoor unit.
Step 5: Connect the Refrigerant Lines
- Verify that the refrigerant lines are connected securely to both the indoor and outdoor units.
- Tighten the flare nuts using a torque wrench according to the manufacturer’s specifications.
Step 6: Vacuum the System
- Connect the vacuum pump to the service port on the indoor unit.
- Turn on the vacuum pump and allow it to evacuate the system for at least 30 minutes.
- Close the service port once the vacuum has been achieved.
Step 7: Charge the System with Refrigerant
- Connect the manifold gauge set to the service ports on the outdoor unit.
- Open the high-pressure service port slightly and slowly charge the system with refrigerant.
- Monitor the pressures on the gauge set and adjust the flow of refrigerant as needed.
- Once the system is fully charged, close the service port.
Step 8: Test the System
- Turn on the air conditioner and allow it to run for at least 30 minutes.
- Check for any leaks or unusual noises.
- Verify that the system is cooling the space effectively.
Troubleshooting
- If the system is not cooling properly, check for leaks in the refrigerant lines or connections.
- If the system is making unusual noises, check for loose components or obstructions in the air flow.
- If the system is tripping the circuit breaker, check for electrical shorts or overloads.
