- Attach the red hose (high side) to the high-pressure service port.
- Connect the yellow hose to the vacuum pump.
Make sure all connections are secure to avoid leaks during the vacuuming process.
Step 2: Start the Vacuum Pump
With your connections secured, turn on the vacuum pump. Allow the pump to operate for a minimum of 15-30 minutes. This time will help ensure that all air and moisture are evacuated from the refrigeration system. You may monitor the pressure on the gauges; they should drop to near-zero.
Step 3: Observe the Gauges
Monitor the gauges carefully:
Low Side (Blue Gauge):
If this gauge shows a drop to below 29 inHg (inches of mercury), it indicates a good vacuum.
High Side (Red Gauge):
This gauge typically doesn’t drop as low as the low side and is less critical for vacuuming but should exhibit a negative reading.
Step 4: Hold the Vacuum
Once you achieve the desired vacuum pressure, hold the vacuum for an additional 15-30 minutes. This step is crucial for ensuring that your system is properly evacuated of air and moisture.
Step 5: Turn Off the Vacuum Pump
After ensuring that the gauges are stable, turn off the vacuum pump and detach the yellow hose from the pump. Always use caution when removing hoses to avoid potential bursts of refrigerant escaping.
Step 6: Close Service Ports
After removing the hoses, make sure to securely close the service ports. This step is essential to maintaining the vacuum in your refrigerator.
Step 7: Restart Your Refrigerator
Finally, plug your refrigerator back in and allow it to start cooling. Monitor its performance over the next few days to ensure it operates efficiently.
