- Kältemittelauswahl: Press the refrigerant selection button (if available, or cycle through modes) to choose the appropriate refrigerant type for your system.
- Zeroing Pressure: With all hoses disconnected and valves closed, press the "ZERO" button to zero the pressure readings.
5.2 Initial Setup of LMC-100A+ Refrigerant Scale
- Einlegen der Batterie: Install batteries into the scale's remote display unit.
- Platzierung: Stellen Sie die Waage auf eine ebene, stabile Oberfläche.
- Einschalten: Press the "POWER" button on the remote display.
- Einheitenauswahl: Press the "UNIT" button to select the desired weight unit (Kg, Lb, or Oz).
- Zeroing Scale: Ensure nothing is on the scale platform, then press the "Z/T" (Zero/Tare) button to zero the reading.
5.3 Initial Setup of ILD-200 Infrared Leak Detector
- Einlegen der Batterie: Open the battery compartment and insert the specified battery (e.g., 3.7V 3000mAh).

- Empfindlichkeitseinstellung: Use the "SENS" button to cycle through sensitivity levels (e.g., H for High, M for Medium, L for Low) based on the expected leak size.
6. Bedienungsanleitung
6.1 Using the LMG-10 Digital Manifold Gauge
- Schläuche anschließen:
- 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.
- Lesungen: 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.
- Staubsaugen:
- 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.
- Laden/Wiederherstellung:
- 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
- Platzieren Sie den Panzer: Place the refrigerant tank securely on the center of the scale platform.
- Eigengewicht: 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.
- Gewicht des Monitors: As refrigerant is charged or recovered, the display will show the net change in weight.
- Hold-Funktion: Some models may have a "HOLD" button to freeze the current reading.
6.3 Using the ILD-200 Infrared Leak Detector
- Einschalten und Aufwärmen: Turn on the ILD-200 and allow it to warm up as indicated by the device (usually a few seconds).
- Empfindlichkeit auswählen: Choose the appropriate sensitivity (H, M, L) based on the suspected leak size and environment. Start with high sensitivity for general scanning.
- Scanbereich: Slowly move the probe tip around suspected leak points (e.g., fittings, valves, coils) at a rate of approximately 1-2 inches per second.
- 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.
- Lecks aufspüren: 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.
- Reset-Funktion: Use the "RESET" button to clear the current reading and re-zero the sensor in a clean air environment.
- Mute-Funktion: Use the "MUTE" button to silence the audible alarm if desired.
