6.1 Using the LMG-10 Digital Manifold Gauge
- గొట్టాలను కనెక్ట్ చేయండి:
- Connect the blue hose to the low-side service port of the HVAC system and the blue port on the LMG-10.
- Connect the red hose to the high-side service port of the HVAC system and the red port on the LMG-10.
- Connect the yellow (service) hose to the center port of the LMG-10. This hose will be used for vacuum pump or refrigerant tank connections.
- Attach Temperature Clamps: Securely attach the temperature clamps to the suction line (low-side) and liquid line (high-side) of the system to measure pipe temperatures for superheat/subcooling calculations.
- రీడింగ్లు: Once connected, the LMG-10 will display real-time pressure and temperature readings. Superheat and subcooling values will be calculated automatically based on the selected refrigerant.
- వాక్యూమింగ్:
- Connect the yellow hose to a vacuum pump.
- Open both high and low-side valves on the LMG-10.
- Start the vacuum pump and monitor the vacuum reading on the LMG-10.
- Once the desired vacuum level is reached, close both valves on the LMG-10 and turn off the vacuum pump.
- Charging/Recovery:
- Connect the yellow hose to the refrigerant tank (for charging) or recovery machine (for recovery).
- Use the LMC-100A+ scale to monitor the refrigerant weight.
- Open the appropriate valve(s) on the LMG-10 to allow refrigerant flow.
- Monitor pressure and temperature readings during the process.
