Safety Information
Always read and understand all safety precautions before operating the Fieldpiece SM380V. Failure to follow these instructions may result in injury or damage to the device.
- Personal Protective Equipment: Always wear appropriate personal protective equipment (PPE), such as safety glasses and gloves, when working with refrigerants and HVAC/R systems.
- Refrigerant Handling: Handle refrigerants with extreme care. Refer to local regulations and industry standards for safe handling and disposal.
- Pressure Safety: Never exceed the maximum pressure ratings of the manifold or the system being tested. Ensure all connections are secure before applying pressure.
- Battery Safety: Use only the specified battery type (6 AA batteries). Do not mix old and new batteries, or different types of batteries. Dispose of batteries according to local regulations.
- Environmental Conditions: Operate the device within its specified environmental limits. Avoid exposure to extreme temperatures, moisture, or corrosive substances.
- Servicing: Do not attempt to service the unit beyond routine maintenance. Refer all servicing to qualified personnel.
What's in the Box
Upon opening the package, verify that all the following items are present:
- Fieldpiece SM380V SMAN Manifold
- Micron gauge (integrated)
- 6 AA batteries (pre-installed or included separately)
- User Manual (this document)
Setup
1. Battery Installation
The SM380V requires 6 AA batteries for operation. These are typically included. To install or replace batteries:
- Locate the battery compartment on the rear of the manifold.
- Open the battery cover.
- Insert 6 AA batteries, ensuring correct polarity as indicated inside the compartment.
- Close the battery cover securely.
2. Initial Power On
Press the POWER button to turn on the manifold. The display will illuminate and show the default measurement screen.
3. Unit Selection (Optional)
To customize units of measurement (e.g., pressure, temperature):
- Press the MENU button.
- Navigate to the "Units" or "Settings" option using the arrow buttons.
- Press ENTER to select.
- Adjust individual units as desired and confirm changes.
Operating Instructions
1. Connecting to a System
The SM380V features three ports for connecting to HVAC/R systems:
- Low Side Port: Typically connected to the suction line.
- High Side Port: Typically connected to the liquid line.
- Service Port: Used for vacuum, charging, or recovery.
Ensure all hoses are properly connected and tightened before opening valves or applying pressure.
2. Taking Measurements
Once connected, the SM380V will display real-time pressure and temperature readings. Use the VIEW button to cycle through different display modes, such as superheat, subcooling, and micron readings.
The integrated micron gauge provides precise vacuum measurements, crucial for proper system evacuation.
3. Data Logging
The SM380V can log up to 9 jobs internally, with continuous logging for up to 168 hours (7 days). To initiate data logging:
- Press the MENU button.
- Select "Data Logging" and press ENTER.
- Follow the on-screen prompts to start a new log or view existing logs.
- Logged data can be downloaded via the USB port for further analysis.
4. Tightness Test
Perform a tightness test to check for leaks after repairs or installations:
- Press the TEST TIGHTNESS button.
- The manifold will display the pressure differential over time and track the duration of the test.
- The test is temperature compensated to avoid false positives, especially when using an SL temp probe.
5. Wireless Measurements
The SM380V can receive wireless measurements from compatible Fieldpiece probes (e.g., Joblink probes). Ensure wireless functionality is enabled on both the manifold and the probes. Refer to the specific probe's manual for pairing instructions.
Maintenance
Cleaning
Wipe the manifold with a damp cloth. Do not use abrasive cleaners or solvents. Ensure the ports are free of debris before and after use.
Storage
Store the SM380V in its protective case in a cool, dry place when not in use. Remove batteries if storing for extended periods to prevent leakage.
Calibration
Regular calibration ensures the accuracy of your SM380V. Refer to Fieldpiece's official website or contact customer support for recommended calibration intervals and procedures.
