Take away any flammable supplies from the neighborhood, as depressurizing the system can launch refrigerant fuel.
Depressurization Process
- Find the service ports on the A/C unit, usually labeled “low” and “excessive”.
- Join the vacuum pump to the “low” service port utilizing a refrigerant-specific hose.
- Safe the connection between the hose and the service port tightly.
- Activate the vacuum pump and monitor the strain gauge to watch the system’s depressurization.
- Enable the pump to function till the strain gauge reads under 15 inches of mercury (inHg), indicating ample depressurization.
- Shut the valve on the vacuum pump to stop air from re-entering the system.
- Disconnect the vacuum pump and take away the hoses.
Suggestions for Efficient Depressurization
| Tip | Description |
|---|---|
| Use a high-quality vacuum pump | Ensures environment friendly and thorough depressurization. |
| Monitor the strain gauge fastidiously | Prevents over-depressurization, which might injury the system. |
| Join the hoses securely | Prevents refrigerant loss and air leakage. |
