• Always wear appropriate personal protective equipment (PPE), including safety glasses and gloves, when working with refrigerants.
• Ensure proper ventilation in your work area to prevent the accumulation of refrigerant gases.
• ຢ່າໃຫ້ອຸປະກອນຖືກອຸນຫະພູມສູງ ຫຼື ແສງແດດໂດຍກົງ ຫຼື ຄວາມຊຸ່ມ.
• Handle refrigerant hoses and connections with care to prevent leaks and accidental discharge.
• ໃຊ້ອຸປະກອນຕາມຈຸດປະສົງຂອງມັນເທົ່ານັ້ນຕາມທີ່ໄດ້ອະທິບາຍໄວ້ໃນຄູ່ມືນີ້.
• ຮັກສາອຸປະກອນໃຫ້ໄກຈາກເດັກນ້ອຍ ແລະບຸກຄະລາກອນທີ່ບໍ່ໄດ້ຮັບອະນຸຍາດ.

• Digital HVAC Gauges Unit
• 3 PCS Reinforced Hoses

4. ຜະລິດຕະພັນເກີນview

The MOTOCOCHE Digital HVAC Gauges feature a robust design with intuitive controls and a clear digital display for accurate readings.

The gauge provides a dual display interface for simultaneous high and low pressure readings, crucial for comprehensive system diagnostics.

5. ການຕິດຕັ້ງແລະການກະກຽມເບື້ອງຕົ້ນ

Before operating the digital gauges, ensure proper connection of the reinforced hoses.

1. ກວດ​ສອບ​ທໍ່: Check the three 5-foot reinforced Freon hoses for any signs of damage or wear. These hoses are designed to withstand pressures up to 600 psi (working) and 3,000 psi (burst).
2. ເຊື່ອມຕໍ່ທໍ່: Attach the appropriate 1/4" male fittings of the hoses to the corresponding ports on the digital manifold gauge. Ensure connections are secure and hand-tightened to prevent leaks. The hose ports are equipped with non-slip gaskets to reduce leakage risk.
3. ເປີດ: Press the power button on the digital manifold gauge to turn it on. The display will illuminate.

6. ຄໍາແນະນໍາການດໍາເນີນງານ

The MOTOCOCHE Digital HVAC Gauges offer three primary working modes for various diagnostic tasks:

6.1. Refrigerant Pressure Mode

This mode is used for measuring the pressure of refrigerants within the system. The gauge has a built-in database of 90 refrigerants (e.g., R11, R134A, R410A) and their corresponding temperature sheet data, compliant with US NIST standards. The real-time pressure detection allows for obtaining the corresponding saturation temperature value, which is convenient for calculating subcooling/superheating.

6.2. Vacuum Percentage ໂຫມດ

This mode displays the current vacuum pressure and the percentage of the vacuum level. When setting the ultimate vacuum, press the "—" key to reset zero. After vacuumizing, the LCD will display percentages like "97%", "98%" after 3-5 minutes, indicating the vacuum degree. A higher percentage signifies a higher vacuum degree.

6.3. Leak Detection Mode

Utilize this mode to identify potential refrigerant leaks within the system. Follow standard leak detection procedures in conjunction with the gauge's readings.

6.4. Full-Featured Functions

• ປິດເຄື່ອງອັດຕະໂນມັດ: The device is equipped with an automatic power-off function to conserve battery life.
• ການປ່ຽນຫົວ ໜ່ວຍ: Easily switch between multiple pressure units (KPa, Bar, PSI, InHg, Kgf/cm) and temperature units (°C, °F).
• ຟັງຊັນ Backlight: The display features a backlight for improved visibility in various lighting conditions.

7. ການບໍາລຸງຮັກສາແລະການດູແລ

Proper maintenance ensures the longevity and accuracy of your digital HVAC gauges.

• ທໍາຄວາມສະອາດ: ເຊັດອຸປະກອນດ້ວຍຜ້າອ່ອນໆ, ແຫ້ງ. ຢ່າໃຊ້ເຄື່ອງເຮັດຄວາມສະອາດຂັດຫຼືສານລະລາຍ.
• ການເກັບຮັກສາ: Store the gauges in a clean, dry place away from direct sunlight and extreme temperatures.
• ການປ່ຽນແບັດເຕີຣີ: When the battery indicator shows low power, replace the batteries promptly to ensure accurate readings. Refer to the battery compartment for specific battery type.
• ການກວດກາທໍ່: Regularly inspect the hoses for cracks, kinks, or damage. Replace them if any wear is detected.
