6. Setup sareng Sambungan Awal

Before operating the digital manifold gauge, ensure all connections are secure and appropriate for the refrigeration system you are working on.

1. Daya Hurung: Pencét tombol daya pikeun ngaktipkeun alat.
2. Sambungkeun hoses:
   • Connect the blue hose to the low side pressure port on the manifold and to the low-pressure service port of the refrigeration system.
   • Connect the red hose to the high side pressure port on the manifold and to the high-pressure service port of the refrigeration system.
   • Connect the yellow hose to the filling/recycling/vacuuming port on the manifold. This hose will be connected to a vacuum pump, refrigerant tank, or recovery unit as needed.
3. Attach Temperature Clamps: Securely attach the wired temperature clamps to the refrigerant lines (e.g., suction line for low side temperature, liquid line for high side temperature) to measure pipe temperatures accurately. Plug the clamps into the designated temperature sensor inputs on the manifold.
4. (LMG-10W Only) Bluetooth Connection: If using the LMG-10W model, ensure Bluetooth is enabled on your mobile device and pair it with the manifold gauge via the Elitech app for extended refrigerant libraries and data logging.

7. Operasi

The Elitech Digital Manifold Gauge offers various modes and functions to assist with HVAC/R diagnostics and servicing.

7.1 Dual Channel Pressure and Temperature Measurement

The device accurately measures and displays real-time pressure and temperature values from both the high and low sides of the refrigeration system. This data is crucial for assessing the system's operating status.

7.2 Refrigerant Type Selection and Saturation Temperature

The manifold gauge has 88 refrigerant types built-in. The LMG-10W model, when connected to the app, can access over 140 refrigerant types. This allows for quick model switching and real-time display of the corresponding saturation temperature.

7.3 Superheat and Subcooling Measurement

The device automatically calculates and displays superheat and subcooling values. These measurements are critical for diagnosing the operating status of air conditioning and refrigeration systems and ensuring optimal efficiency and equipment security.

7.4 Modeu operasi

The manifold gauge supports multiple operating modes, which can be switched as needed:

7.5 Pressure Holding and Leakage Testing Mode

This mode allows for scientific determination of the system's operating status by testing for pressure leaks.

1. Daya Hurung: Ensure the equipment is powered on.
2. Sistim Sambungkeun: Connect the manifold to the inline refrigeration system.
3. Buka klep: Ensure the black valve on the manifold is open.
4. Lebetkeun Mode: Press the designated key combination (refer to your device's specific button layout) to enter the "hold" pressure holding mode.
5. Mimitian Test: Press the start/stop button to begin holding the pressure. The display will show the timer, initial pressure, current pressure, and pressure difference value.
6. Réngsé Tés: Press the start/stop button again to end the test.
