The NAVAC NX4 Nexus Digital Manifold Gauge is an advanced tool designed for HVAC diagnostics. It features a 4-valve configuration, including a 3/8" vacuum port, allowing for efficient multi-task operations and fast evacuations. The device offers wireless connectivity to Bluetooth-enabled temperature probes and micron gauges, providing comprehensive remote insights directly on its digital screen. The NX4 is built with a robust aluminum body and an impact-resistant rubber cover for durability in field conditions, ensuring precise readings with Class 0.4 accuracy.
זיכערקייַט אינפֿאָרמאַציע
- Always wear appropriate personal protective equipment (PPE), including safety glasses and gloves, when working with refrigerants.
- Ensure proper ventilation in the work area to prevent accumulation of refrigerant gases.
- Do not expose the manifold gauge to extreme temperatures or direct sunlight for prolonged periods.
- Verify that all connections are secure before pressurizing the system.
- Refer to local regulations and industry standards for safe handling of refrigerants.

סעטאַפּ
- טשאַרדזשינג די אַפּאַראַט: Connect the provided USB-A to USB-C charging cable to the NX4 unit and a suitable USB power adapter. Ensure the unit is fully charged before first use. A full charge typically takes several hours.
- מאַכט אויף: Press and hold the power button on the manifold gauge until the digital display illuminates.
- Connecting Temperature Clamps:
- Ensure the Bluetooth temperature clamps (NST1 and NST2) are powered on.
- The NX4 will automatically attempt to pair with nearby NAVAC Bluetooth devices. Follow on-screen prompts if any pairing confirmation is required.
- Attach the NST1 (Low Side) clamp to the suction line and the NST2 (High Side) clamp to the liquid line of the HVAC system.
- קישקע קאַנעקשאַנז:
- Connect the appropriate refrigerant hoses to the 1/4" SAE ports for suction line, liquid line, and refrigerant recovery/charging.
- Utilize the dedicated 3/8" SAE vacuum port for fast evacuation procedures.
- App Integration (Optional): Download the MyNAVAC App from your device's app store. Connect the NX4 to the app via Bluetooth for advanced features, data logging, and firmware updates.
אַפּערייטינג מאָדעס
The NAVAC NX4 offers four distinct operational modes to cover various HVAC diagnostic and service needs. Use the מאָדע button to cycle through them and the אַרייַן קנעפּל צו באַשטעטיקן סאַלעקשאַנז.
- Manifold Mode:
This is the primary mode for real-time pressure and temperature readings. It displays high-side and low-side pressures, saturation temperatures, superheat, and subcooling values. Ideal for general system analysis and charging.
- Leak Test Mode:
Used to detect leaks in a system. The manifold gauge monitors pressure changes over a set period. If the pressure drops beyond a configurable threshold, it indicates a potential leak.
- עוואַקואַציע מאָדע:
Designed for monitoring the vacuum level during system evacuation. It displays the current vacuum pressure, helping technicians ensure the system reaches the desired deep vacuum level before charging.
- Decay Test Mode:
After evacuation, this mode helps confirm the integrity of the vacuum. It monitors for any pressure rise over time, which would indicate moisture or non-condensable gases remaining in the system, or a leak.

- רייניקונג: ווישן די אַפּאַראַט מיט אַ ווייך, דamp cloth. Do not use abrasive cleaners or solvents. Ensure no liquid enters the ports or display.
- סטאָרידזש: Store the manifold gauge and accessories in the provided carry case in a cool, dry place away from direct sunlight and extreme temperatures.
- באַטערי זאָרגן: For optimal battery life, charge the unit regularly, even if not in frequent use. Avoid completely draining the battery for extended periods.
- Firmware דערהייַנטיקונגען: Periodically check the NAVAC website or the MyNAVAC App for available firmware updates to ensure optimal performance and access to new features.
