Información de seguridade

Always wear appropriate personal protective equipment (PPE), including safety glasses and gloves, when handling refrigerants.
Ensure all hose connections are secure and leak-free before applying pressure or vacuum to a system.
Do not exceed the maximum working pressure of the hoses (500 PSI) or the gauge (800 PSI). Exceeding these limits can cause equipment damage or personal injury.
Use the device in a well-ventilated area to prevent the accumulation of refrigerant vapors.
Refer to local and national regulations for proper refrigerant handling, recovery, and disposal procedures.
Keep the device away from moisture, direct sunlight, and extreme temperatures to prevent damage to electronic components.
Non intente desmontar nin modificar o dispositivo. Encargue calquera mantemento a persoal cualificado.

Configuración

Instalación da batería: Open the battery compartment located on the back of the unit. Insert two AAA batteries, ensuring correct polarity (+/-). Close the compartment securely.
Encendido inicial: Preme o botón de acendido (U symbol) to turn on the device. The LCD screen will illuminate.
Selección de unidades: Use the "MODE" button to cycle through available measurement units (psi, kg/cm², kPa, MPa, bar, inHg for pressure; °C/°F for temperature). Select your preferred units by stopping on the desired option.
Selección de refrixerante: Press the "MODE" button repeatedly until the refrigerant type (e.g., R134a) flashes on the display. Use the up/down arrow buttons to scroll through the list of supported refrigerants. Confirm your selection by pressing "MODE" again or by waiting a few seconds for the selection to auto-confirm.
Zeroing the Pressure: Before connecting the gauge to any system, ensure it is at atmospheric pressure (not connected to any pressure source). Press the "ZERO" button to calibrate the pressure reading to zero. This ensures accurate measurements.

Instrucións de funcionamento

Conexión das mangueiras

Conecta o mangueira azul to the low-pressure service port of the HVAC/R system.
Conecta o mangueira vermella to the high-pressure service port of the HVAC/R system.
Conecta o mangueira amarela to the service port of your vacuum pump, refrigerant tank, or recovery machine.
Ensure all connections are hand-tightened, then slightly snugged with a wrench to prevent refrigerant leaks.

Medición de presión e temperatura

With the hoses connected to the system, slowly open the appropriate valve knobs on the manifold gauge to allow system pressure to reach the internal sensors.
The LCD will display real-time pressure readings for both the high and low sides of the system.
Simultaneously, the display will show the corresponding saturation temperatures (evaporation and condensation temperatures) for the currently selected refrigerant.
The "PT" (Pressure-Temperature) mode shows pressure and saturation temperature. "Ev" (Evaporation) and "Co" (Condensation) indicate the saturation temperatures, while "PL" (Low Pressure) and "PH" (High Pressure) indicate the actual system pressures.

Refrigerant Charging/Recovery

The DMG-2SE provides accurate pressure readings essential for refrigerant charging and recovery processes. Always follow industry best practices and local regulations for these operations.

Para cargar: Connect the yellow hose to the refrigerant tank. Purge any air from the yellow hose before opening the manifold valve to the system. Monitor the pressure readings on the DMG-2SE to ensure the correct charge is added.
For Recovery: Connect the yellow hose to a certified refrigerant recovery machine. Follow the recovery unit's instructions and monitor system pressures on the DMG-2SE during the recovery process.

Mantemento

Limpeza: Limpe o dispositivo cun suave, damp pano. Non empregue produtos de limpeza abrasivos nin solventes, nin mergulle a unidade en auga.
Substitución da batería: Replace batteries when the low battery indicator appears on the display. Ensure the device is powered off before opening the battery compartment and replacing the two AAA batteries.
Inspección da mangueira: Regularly inspect all refrigerant hoses for signs of wear, cracks, cuts, or damage. Replace damaged hoses immediately to prevent refrigerant leaks and ensure safety.
Almacenamento: Store the manifold gauge set in a clean, dry place, away from direct sunlight, extreme temperatures, and corrosive environments.
