6. Istruzzjonijiet Operattivi

6.1 Using the LMG-10 Digital Manifold Gauge

1. Qabbad Manek:
   • 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.
2. 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.
3. Qari: 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.
4. Vacuuming:
   • 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.
5. 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.

6.2 Using the LMC-100A+ Refrigerant Scale

1. Place Tank: Place the refrigerant tank securely on the center of the scale platform.
2. Piż tat-tara: Press the "Z/T" button to tare the weight of the tank, setting the display to zero. This allows you to measure only the amount of refrigerant added or removed.
3. Piż tal-monitor: As refrigerant is charged or recovered, the display will show the net change in weight.
4. Funzjoni ta' Żomm: Some models may have a "HOLD" button to freeze the current reading.

2. Agħżel Sensittività: Choose the appropriate sensitivity (H, M, L) based on the suspected leak size and environment. Start with high sensitivity for general scanning.
3. Żona ta' Skennjar: Slowly move the probe tip around suspected leak points (e.g., fittings, valves, coils) at a rate of approximately 1-2 inches per second.
4. Detecting Leaks: When a leak is detected, the device will emit an audible alarm and/or visual indication (e.g., LED bar graph, display reading). The alarm frequency or intensity typically increases with the concentration of refrigerant.
5. Pinpointing Leaks: Once a leak is indicated, move the probe away and then slowly approach the area again to pinpoint the exact source. Reduce sensitivity if the alarm is constant and overwhelming.
6. Irrisettja Funzjoni: Use the "RESET" button to clear the current reading and re-zero the sensor in a clean air environment.
7. Funzjoni Mute: Use the "MUTE" button to silence the audible alarm if desired.
