Important Notice Quick Start Class A2L/A2/A3 Refrigerant Safety Notice What’s Included This is not a consumer product. Only qualified personnel trained in service and installation of A/C and/or refrigeration equipment shall use this product. Read and understand this operator’s manual in its entirety before using your SMAN Refrigerant Manifold to prevent injury or damage to you or equipment.
Description SMAN™ Refrigerant Manifolds give you the trust needed for doing the job right the first time. Your new Fieldpiece manifold has been upgraded for ultimate field protection and long range wireless communication. The fully rubberized case seals and protects from dust, bumps, and light rain. Use the heavy duty hook to hang it in your work vehicle while protected by its large padded soft case. Model SM380V is your testing hub at the jobsite.

Operation Buttons A beep sounds when a button is pressed. A double beep sounds when a button is pressed and the function is not possible at that time. The speaker can be muted altogether (page 22). Press 2 sec to toggle power. Press to toggle backlight. Scroll through refrigerants or change values. ENTER: Confirm a changed value or activate an ALARM (page 18). MENU: Enter the menu (page 22) or exit a mode. VIEW: Display ODDB, TSH, or T1-T2 (page 15).
Superheat (SH) and Subcooling (SC) Superheat is the amount of heat added to refrigerant after changing to a vapor in the evaporator. Subcooling is the amount of heat removed from refrigerant after changing to a liquid in the condenser. View both live at the same time! 1. 2. 3. 4. 5. 6. 7. 8. 9. Use ARROWS to select the system refrigerant. Close all manifold valves. Connect EPA approved refrigerant hoses to LOW and HIGH side ports. Fully plug pipe clamp thermocouples into SLT and LLT rear jacks.
Deep Vacuum Follow recommended evacuation practices from equipment manufacturer and training. Alarms can be adjusted in the MENU (page 28). 1. Close all manifold valves (including shutoff valve to pump). 2. Setup your tools and equipment (see diagram). Connect HIGH port to liquid line service port. Connect LOW port to suction line service port. Connect refrigerant (middle) port to vacuum pump making sure to have a shutoff valve between the pump and manifold. 3. Turn on your vacuum pump. 4.
Test Tightness (Pressure Test) After working on a refrigerant-side component of an emptied system, it’s a good idea to pressurize the system with dry nitrogen and check for pressure drops before evacuation. 1. Pressurize the system with dry nitrogen. Pressure levels vary with the equipment you’re testing. Always check with the manufacturer. 2. Connect the low side (suction line) port to the system and wait for the pressure to stabilize.
Menu Press MENU to enter the menu where most settings are located. Use arrows to scroll through the menu and press ENTER to select one of the below menu items. LogData: Enter data logging setup mode (page 23). (StopLog): If data logging, stop the log (page 23). AutoOff: Enter auto off timer setup mode (page 24). CalTemp: Enter calibration mode for Type K jacks (page 25). Wireless Sources: Enter wireless source setup mode (page 26). TSH Sources: Enter target superheat source setup mode (page 27).
Auto Power Off (APO) To save battery life, your SMAN manifold automatically powers off after a set time of no button presses. MENU/AutoOff 1. Use ARROWS to scroll through times (default is 30 min). 2. Press ENTER to select and exit. If changes were made, choose whether or not you want to save changes. • Press MENU to exit at any time. If changes were made, choose whether or not you want to save changes. • APO is automatically disabled when data logging.
Wireless Measurement Sources Assign wireless Job Link system tools to core manifold measurements such as pipe temperature or to broader measurements such as refrigerant weights and psychrometrics. Wireless OFF: Line temperatures (SLT and LLT) are automatically assigned to their type K jacks. Wireless ON: SLT and LLT type K jacks DO NOT override an assigned wireless source. MENU/Wireless Sources 1. Use ARROWS to scroll through the list of measurements. 2. Press ENTER to select. 3.
Units Backlight Timer Each measurement can have its own unit of measure. The backlight turns off automatically after a set time of no button presses. MENU/Units MENU/Backlight Timer 1. 2. 3. 4. Use ARROWS to scroll through the list of measurements. Press ENTER to select. Use ARROWS to scroll through units of measure. Press ENTER to select and return to the list of measurements. • Press MENU to exit at any time.
Advanced Pressure Calibration Typical HVACR service does not require this procedure, but you can occassionally calibrate the pressure sensors to maintain highest accuracy. It works by measuring the temperature of virgin refrigerant and applying an offset to match the pressure to that refrigerant’s P-T chart. 1. Calibrate a beaded thermocouple to the ODDB jack (page 25). 2. Store a virgin refrigerant cylinder, upright and untouched, in the stable ambient environment for at least 24 hours. 3.
Firmware View and Update Firmware often becomes available as new refrigerants and features become available. Before entering this mode, download from www.fieldpiece.com and transfer from the computer to the manifold via the micro USB port on the side. Or you can initiate an update over the air from your mobile device running the Job Link system mobile app while the version is displayed. Restore User Settings Restore factory default user settings when you want a fresh start. MENU/Restore Settings 1.
Delete Log File Clear up space by deleting old logs or just view free space available. MENU/Delete Log File 1. Use ARROWS to scroll through Jobs (logs). The display will alternate between the % free space on the drive and the % of space the chosen Job uses. 2. Press ENTER to select a Job to delete. Choose whether or not you want to delete that Job. 3. If you choose to delete, it may take a few seconds to finish. If no more Jobs are found, the manifold returns to standard operation.
