• How long is the warranty for my SMAN refrigerant manifold?

  • All of our products have a 1-year warranty from date of purchase.

• Why do my microns jump up when I turn off my vacuum pump?

  • A number of effects may be affecting the vacuum pressure reading immediately after closing the VAC valve (on a 4-port manifold) and turning off the vacuum pump

    • Vacuum pressure is equalizing across the system from the manifold vacuum sensor to the farthest point from the vacuum sensor.
    • Dissolved moisture or refrigerant are outgassing from the compressor oil or other areas of the system
    • There is a small leak somewhere downstream from the vacuum sensor in the manifold.  This may be in the manifold, hose connections, or HVAC system.

• Why do my microns jump up when I close my High Side and Low Side valves?

  • You have isolated the micron gauge from the system, you are now only reading what is inside your manifold and the hose to the vacuum pump.

• Why is my vacuum measurement inaccurate?

  • When comparing your integrated vacuum sensor in your manifold to an external vacuum gauge, you may see a difference in the measurement.  Each vacuum sensor (internal or external gauge) will have some accuracy tolerance.  Additionally, depending on the location of each vacuum sensor relative to the vacuum pump, the observed vacuum pressures may be different.  After taking these into account, check the following:

    • The vacuum sensor is dirty – Clean sensor periodically with isopropyl alcohol
    • The manifold block has trapped non-condensables – Flush & clean the manifold block
    • The attached hoses are dirty – Flush & clean the hoses

• How do I manually set my IDWB and ODDB?

  • • From the main screen, press the MENU button, use the arrow buttons to navigate to the TOOL SET menu option, press the SELECT button

    • Use the arrow buttons to navigate to the Return option for IDWB or Outdoor option for ODDB.

    • Press the SELECT button.

    • Use the arrow buttons to select “Manual” for manual entry and press the SELECT button.

    • Use the arrow buttons to adjust the set temperature by 0.1 degree increments and press SELECT to lock in the desired setting. The SMAN will return to the main screen.

• How do I update my manifold firmware?

  • Visit http://www.fieldpiece.com/support/downloads to download the latest firmware for your SMAN product. After downloading the firmware update, run the .exe file and follow the instructions on your PC.

• Why does my superheat/subcooling read -O/L?

  • • Verify you have the correct refrigerant selected.
    • Verify you have the Low side hose connected to the Suction line and High side hose connected to the Liquid line.
    • Verify you have the correct pipe clamps (SLT & LLT) connected to the correct system pipes.
    • You may have a negative degree of superheat or subcooling.

    To verify Subcooling is calculating properly:
    • Plug in thermocouple into LLT port and change refrigerant to R113. Verify the manifold calculates a correct subcooling value at the indicated LLT.

    Superheat is not working-
    • Plug in thermocouple into SLT port and change refrigerant to R407F. Verify the manifold calculates a correct superheat value at the indicated SLT.

• How do I clean my manifold?

  • Over time, the vacuum sensor of the SMAN may become contaminated with dirt, oil, and other contaminants.  If you are frequently flowing refrigerant through the manifold and exposing the vacuum sensor to this flow, we recommend that users should flush or clean their manifold every 2 to 4 weeks to extend the life of the SMAN by avoiding contaminants from building up on the sensor components.

    1. Never use an object such as a cotton swab to clean the sensor, you may cause damage to the sensor.
    2. Open all valves and cap all the ports except for the VAC port on a 4-port manifold or the center port on a 3-port manifold. Turn the manifold over such that the manifold ports (not hose holders) are facing up.
    3. Drop enough Isopropyl (rubbing) alcohol (minimum 70% alcohol content) into the VAC/center port using an eye dropper or funnel so that it can flush out contaminants. (Roughly 7mL)
    4. Cap off the VAC/center port and gently shake your SMAN while upside down to clean sensor. (Approximately 30 to 60 seconds.)
    5. Turn right side up. Uncap one of the ports and pour out the rubbing alcohol. Uncap and open all ports to allow sensors to dry out. Drying usually takes about an hour.

• How do I calibrate my temp?

  • • Using an Ice bath approximately 70% ice 30% water, place the pipe clamp in the ice water and stir for approx. 15-20 seconds.

    • Press the MENU button and toggle with the arrow buttons to the “CalTemp” option and press the SELECT button.

    • Use the arrow buttons to select the desired temperature to calibration and press the SELECT button.

    • The selected temperature value will flash on the screen, use the arrow buttons to adjust the temperature to match 32.0 °F (0.0 C).

    • Press the SELECT button to save the updated value and return to the list of temperatures.

    • Repeat this process for any additional clamps that require calibration or press the MENU button to return to the main screen.

• Why does my manifold shock me?

  • When charging a system, recovering or discharging your hoses, ESD (electrostatic discharge) is created and can give out enough electricity to shock you. Proper grounding will avoid this issue.

• How do I perform advance pressure calibration?

  • The Advanced Pressure Calibration procedure is detailed in the SM382V and SM482V user manual.

• How do I link my JL3RH to capture ODDB?

  • Automated Linking:
    • From the main screen, press the LINK TOOL button.
    • When prompted with “Search?” select YES and press the SELECT button.
    • The SMAN will detect and display the available JL3RH tools for linking. Use the up and down arrow buttons until the desired “ID-####” is displayed with the ODDB measurement.
    • Press the SELECT button. The SMAN will display “Linked” and return to the main screen.

    Manual Linking:
    • From the main screen, press the MENU button, use the arrow buttons to navigate to the TOOL SET menu option, press the SELECT button
    • Use the arrow buttons to navigate to the “Outdoor” option for ODDB.
    • Press the SELECT button.
    • Use the arrow buttons to select the desired “ID-####” for the JL3RH.
    • Press the SELECT button. The SMAN will display “Linked” and return to the main screen.
