Setup

Before operating the Elitech HVAC/R service kit, ensure all components are properly set up and charged.

1. Unpacking: Carefully remove all items from the packaging. Verify that all components listed in the packing list are present and undamaged.
2. Battery Installation/Charging:
   • LMG-10W: Ensure the manifold gauge is charged or has sufficient battery life. Refer to the individual LMG-10W manual for specific battery type and charging instructions.
   • LMC-100A+: Install batteries as per the scale's instructions.
   • ILD-200: Charge the leak detector using the provided charger until the battery indicator shows full.
3. App Installation (Optional but Recommended): Download the "Elitech Tools" app from your device's app store (iOS and Android). This app allows for integrated management of Elitech tools.
4. Initial Calibration/Zeroing:
   • LMG-10W: Power on the manifold gauge. Perform a zero calibration as instructed in its specific manual to ensure accurate pressure readings.
   • LMC-100A+: Place the scale on a flat, stable surface. Power it on and press the "Z/T" button to zero the scale before placing any refrigerant cylinders on it.
   • ILD-200: Allow the leak detector to warm up as per its instructions. Ensure it is in a clean air environment when powered on to establish a baseline.
5. Hose Connection (LMG-10W): Connect the appropriate refrigerant hoses to the LMG-10W manifold gauge and to the HVAC/R system service ports as required for your specific task (e.g., charging, recovery, evacuation).

Operating Instructions

This section provides general operating guidelines for using the Elitech HVAC/R service kit. Always refer to the specific manuals for each device for detailed operational procedures.

Refrigerant Charging/Recovery (Using LMG-10W and LMC-100A+)

1. Connect Hoses: Connect the LMG-10W to the HVAC/R system's high and low-pressure service ports using the appropriate hoses. Connect the center hose to the refrigerant cylinder or recovery machine.
2. Place Cylinder on Scale: Place the refrigerant cylinder on the LMC-100A+ scale. Ensure the scale is zeroed before placing the cylinder.
3. Monitor Readings: Use the LMG-10W to monitor system pressures and temperatures. The LMC-100A+ will display the refrigerant weight.
4. Charge/Recover: Open the manifold valves as required for charging or recovery. Monitor the LMC-100A+ to ensure the correct amount of refrigerant is transferred.
5. Disconnect: Once the process is complete, close all valves and carefully disconnect the hoses.

Leak Detection (Using ILD-200)

1. Power On: Turn on the ILD-200 leak detector. Allow it to warm up and self-calibrate in a clean air environment.
2. Adjust Sensitivity: Adjust the sensitivity setting (Low, Medium, High) based on the suspected leak size and environment. Start with a higher sensitivity for general scanning.
3. Scan System: Slowly move the probe tip around suspected leak areas (e.g., joints, fittings, valves, coils). The detector will alarm and indicate the presence of refrigerant.
4. Pinpoint Leak: Once a leak is detected, move the probe slowly back and forth to pinpoint the exact source. The alarm intensity will typically increase as you get closer to the leak.
5. Verify: After identifying a leak, ventilate the area and re-scan to confirm the leak location.

Maintenance

Proper maintenance ensures the longevity and accuracy of your Elitech HVAC/R service kit.

• Cleaning:
  • Wipe down all devices with a soft, damp cloth after each use.
  • Do not use abrasive cleaners or solvents.
  • Keep the manifold gauge ports and scale platform free of debris.
• Storage:
  • Store all components in their original carrying cases or a protective environment when not in use.
  • Store in a cool, dry place away from direct sunlight and extreme temperatures.
• Battery Care:
  • For rechargeable devices (LMG-10W, ILD-200), charge regularly, especially before long periods of storage.
  • Remove batteries from the LMC-100A+ if storing for extended periods to prevent leakage.
• Sensor/Probe Care (ILD-200):
  • Keep the sensor tip clean and free from contaminants.
  • Avoid exposing the sensor to excessive moisture or oil.
• Hose Inspection (LMG-10W):
  • Regularly inspect refrigerant hoses for cracks, wear, or damage. Replace if necessary to prevent leaks.
