Recent Refrigerants ( )
A rolling list of your 10 most recent refrigerants, indicated by a ****, is stored above the main list. When you power off your manifold, the current refrigerant is added automatically to this dynamic list of 10.

LINK TOOL
Assign wireless Job Link® System tools to core manifold measurements such as pipe temperature or to broader measurements such as refrigerant weights and psychrometrics.

1. Press LINK TOOL to search for supported Fieldpiece wireless tools.

2. Turn on any wireless sources you want to assign.
   If your Job Link® System tool has a selector switch, ensure it’s set to match the measurement.

3. Use ARROWS to auto-search yes or no.
   Job Link® System tools are displayed by their 4-digit ID, usually found on the back of the tool.

4. Press SELECT to select and return to the list of measurements.

   • Press MENU to exit at any time. If changes were made, choose whether or not you want to save changes.
   • Most Job Link® System tools have a switch that selects a side of the system. Set it to match the measurement you’re assigning it to.
   • A wireless Return psychrometer is assigned to both Return air and IDWB (page 23) when selected.
     NOTE: When adding JL3PC or JL3LC pipe clamps, you will need to disconnect the TC24 Type-K pipe clamps from the manifold.

N2 TEST (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. You can connect the high side (liquid line) as well to help monitor stability, but the pressure differential (P.diF) calculation is only using the low side sensor.
3. Attach the SLT clamp to the pipe you’re going to pressurize.
   • This temperature is used to compensate for any temperature changes between the start and end of the test.
   • Select “Comp. OFF” in MENU to deactivate temperature compensation.
4. Press N2 TEST to prepare the test.
5. Press N2 TEST to start the test.
   • The stopwatch starts.
   • Real-time compensated pressure change is labeled Δ.
   • Real-time temperature is labeled SLT.
   • Real-time temperature change is labeled ΔT.
6. Press N2 TEST to stop the test.
   • The stopwatch, Δ, and ΔT freeze.
   • If Δ is negative, there may be a leak in the system.
   • If Δ is positive, SLT or nitrogen temperature may be unstable. High and low side pressures and SLT continue to display, but they are no longer being used.
7. Press N2 TEST to exit the test.
   • To save battery life, the screen will turn off after 3 hours of testing but will continue to test. Press any button to turn the screen on.

PIPE/AIR
Press PIPE / AIR to display various calculations and measurements from the Job Link® System psychrometers you’ve assigned (page 19). The parameter is briefly shown when pressed, then shown at the top of the LCD.

Press PIPE / AIR for >1 second to view SLT/LLT.

• SLT: Live reading of suction line temperature.
• LLT: Live reading of liquid line temperature.
• RET: Live reading from return air psychrometer.
• SUP: Live reading from supply air psychrometer.
• TΔT: Live target dry bulb split from psychrometers.
• ΔT: Live actual dry bulb split from psychrometers.

T1-T2/TSH/ODDB
Press T1-T2 / TSH / ODDB to cycle through ODDB (outdoor dry bulb), TSH (target superheat), and T1-T2 (middle display – bottom display).

• ODDB: Live reading of the rear ODDB thermocouple jack. ODDB does not show if set to manual value (page 23).
• TSH: Live target superheat calculated from ODDB and IDWB. Each of these measurements can be live or manually entered (page 21).
• T1-T2: Live simple subtraction of the bottom display (T2) from the middle display (T1). With SLT and LLT showing, you can check for a temperature drop across a filter drier. With RET and SUP showing, you can check the effect of the indoor unit. With TΔT and ΔT showing, you can see how close the actual ΔT is to the target.

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. Use ARROWS to select the system refrigerant.
2. Close all manifold valves.
3. Connect EPA-approved refrigerant hoses to LOW and HIGH side ports.
4. Connect your supported wireless pipe clamps, or fully plug pipe clamp thermocouples into SLT and LLT rear jacks. See LINK TOOL on page 19.
5. Hand tightens both the LOW side hose to the suction line service port and the HIGH side hose to the liquid line service port.
6. Clamp the SLT thermocouple to the suction line between the evaporator and compressor, at least 6 inches from the compressor.
7. Clamp the LLT thermocouple to the liquid line between the condenser and metering device, as close to the service port as possible.
8. Purge hoses as you open HIGH and LOW manifold valves.
9. View superheat and subcooling in real-time.
   • Ensure the system has stabilized before using superheating or subcooling to adjust the charge of the system.
   • To add or remove refrigerant connect the tank/cylinder/machine to the REF port. Use the manifold valves to precisely charge or recover refrigerant as needed. Follow recommended charging or recovery practices from equipment manufacturers and training.
   • When superheat and/or subcooling cannot be calculated, “- – – – ” will be displayed. If superheat and/or subcooling is negative, “Below Typical Range” will show. In rare cases this is normal, but usually, a thermocouple is disconnected or the selected refrigerant is incorrect.

Target Superheat (TSH)
Compare target superheat (TSH) to actual superheat (SH) when charging fixed orifice air conditioning systems. TSH is continually calculated from indoor wet bulb (IDWB) and outdoor dry bulb (ODDB) temperatures.

• IDWB: By default, this is a manually set value of 60.0°F.
  For a live measurement, assign the optional model JL3RH wireless psychrometer. See LINK TOOL on page 19.

• ODDB: By default, this is the live measurement of the ODDB thermocouple jack. If you prefer a static measurement, assign a manual value. NOTE: Use your wireless psychrometer (JL3RH or PRH3) by pressing MENU > ToolSet > Outdoor (ODDB flashing) > SELECT > Arrows between Type K / Manual / ID-#### > SELECT.

1. Connect the included type K bead thermocouple to the ODDB thermocouple jack. Use the alligator clip to locate the bead in a shaded area of the condenser to measure the temperature of air entering the condenser.

2. Use ARROWS to scroll through detected measurement sources.
   Job Link® System tools are displayed by their 4-digit ID, usually found on the back of the tool.

3. Turn on any wireless sources you want to assign.
   If your Job Link® System tool has a selector switch, ensure it’s set to match the measurement.

4. Press SELECT to select and exit or go to next until complete.

5. Press T1-T2 / TSH / ODDB until ODDB is displayed.
   If you changed ODDB to a manually set value, it will be used to calculate TSH but will not be displayed.

6. Measure IDWB after the filter, just in front of the indoor coil. If a psychrometer is assigned, you can press AIR PARAMETER until the wet bulb is displayed to verify the measurement.

7. Press T1-T2 / TSH / ODDB until TSH is displayed.

Deep Vacuum – Model SM382V
Follow recommended evacuation practices from equipment manufacturers and training. Alarms can be adjusted in the MENU (page 34).

1. Close all manifold valves.

2. Set up your tools and equipment (see diagram).

   • Connect manifold 1/4” HIGH port to liquid line service port.
   • Connect manifold 1/4” LOW port to suction line service port.
   • Connect the manifold 1/4” middle port to a vacuum pump with a shutoff valve in between.

3. Turn on your vacuum pump.

4. Open shutoff valve.
   The vacuum sensor is now exposed to your pump, but it will not display until HIGH/LOW manifold valves are opened. This ensures the measurement is of the system and not just the manifold.

5. Open HIGH and LOW manifold valves.

6. Press the VAC ALARM to activate the low alarm. See details on page 34. The stopwatch starts. The rate of change is displayed in units per minute. Press ARROWS to switch between Rate Meter and Bar Graph views. The smaller the rate of change, the closer you are to stabilization. You may need to improve your setup if the rate slows well before reaching your desired vacuum (see Tips for Better Evacuations). Note: The Rate Meter shows vacuum progress and eliminates uncertainty with a dynamic view. Bars displayed on the left side show a decreasing vacuum, bars in the center show a stable vacuum and bars on the right side show an increasing vacuum. The Bar Graph is static and nonlinear for increased resolution at deeper vacuums.

7. Once the low alarm level is reached, the backlight blinks and the alarm sounds. Press any button (other than SELECT) to silence the alarm.

8. Close your shutoff valve between the middle port and pump to block the pump.
   Do not close HIGH and LOW valves or you’ll block the system and measure just the manifold!

9. Turn off your vacuum pump.

10. Press VAC ALARM to activate the high alarm and start the stopwatch.

11. Once the high alarm level is reached, the backlight blinks, an alarm sounds, and the stopwatch stops. Press any button (other than SELECT) to silence the alarm.

12. Close HIGH and LOW manifold valves.
    The vacuum sensor is now blocked from the system (page 44).

Tips for Better Evacuations

• Remove Schrader valve cores & depressors with a core removal tool.
• Use the shortest vacuum-rated hoses with the largest diameter available.
• Do not evacuate through hoses with low-loss fittings.
• Inspect the rubber seals at both ends of your hoses for damage.
• Apply a light amount of vacuum oil to the service port fittings before attaching hoses to help maintain a vacuum-tight seal.
• Change pump oil before and during the job. Change pump oil on the fly without losing the vacuum with Fieldpiece vacuum pumps.
• When the vacuum pump is blocked, a slow rise that stabilizes may signify moisture is still present in the system. A continuous rise to the atmosphere indicates a leak. Check hoses, tools, or the system itself.
• Measurements are less representative of the entire system when the vacuum pump is on because pumping creates a pressure gradient. Block the pump and allow the system to stabilize before assuming the measurement is of the entire system.

Deep Vacuum – Model SM482V

Test for Non-Condensables
If head pressure seems high even after cleaning coils, optimizing airflow, and other routine maintenance, you may have non-condensable trapped in the system or a low refrigerant charge. Non-condensables can reduce efficiency, and performance, and put extra stress on system components. Non-condensable can enter the system in many ways, and your initial system service may follow years of poor service that introduced the non-condensable.

1. Use ARROWS to select the system refrigerant.
2. Unpower the compressor, but allow the condenser fan to run.
3. Connect high side port to the system to view system pressure.
4. Clamp one thermocouple to the discharge line.
5. Clamp the other thermocouple to the liquid line.
6. Clip the ODDB thermocouple to measure the air entering the condenser.
7. Monitor all three temperatures until they all stabilize and show the same value.
8. View the subcooling (SC) calculation on the display.
   The closer SC is to 0.0°, the fewer non-condensable are trapped.
   Depending on the system, a negative SC may suggest a need to recover, evacuate, and charge with virgin refrigerant.

Temperature Calibration (CalTemp)

• Thermocouples (T/C) are not calibrated directly. Instead, each T/C jack (LLT, ODDB, SLT) must be calibrated to the particular T/C that is plugged into it. Though a calibration can hold for years, it’s best practice to calibrate regularly if only to verify accuracy.
• Calibration is quick and easy, requiring just a known temperature to calibrate to. Ice water is the recommended medium for in-field calibration due to known temperature (32.0 F, 0.0 C) and ready availability.

MENU/CalTemp

1. Stabilize a large cup of ice water by stirring. Pure, distilled water will be the most accurate.
2. Immerse the sensing end of the thermocouple in the ice water.
3. Use ARROWS to select the temperature you want to calibrate (ODDB, SLT, or LLT).
4. Press SELECT to select.
5. Use ARROWS to adjust the temperature to match 32.0°F (0.0°C) making sure the ice water is continually stirred. The calibration range is limited to ±7°F (±3.8°C) to help prevent mistakes.
6. Press SELECT to save and return to the list of temperatures.
   • Press MENU to exit at any time. If changes were made, choose whether or not you want to save changes.
   • If you have a wireless thermocouple (model JL3PC) assigned and wireless is on, calibration is for the wireless thermocouple.
   • Calibration of a wireless thermocouple (model JL3PC) does not override a wired thermocouple calibration. You can switch between wired and wireless without having to recalibrate.

Advanced Pressure Calibration
Typical HVACR service does not require this procedure, but you can occasionally calibrate the pressure sensors to maintain the highest accuracy. It works by measuring the temperature of virgin refrigerant (not recovered 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 32).

2. Store a virgin refrigerant cylinder, upright and untouched, in a stable ambient environment for at least 24 hours.

3. Leaving the cylinder in the same place it was left to stabilize, connect the cylinder to either the HIGH or LOW side port.

4. Close VAC and REF valves and cap the unused port.
   If you don’t have caps with seals, you can connect both ends of a refrigerant hose to the unused ports or hose seats. Some refrigerant will remain in the hoses which you need to recover after calibration.

5. Use ARROWS to select the refrigerant type in the cylinder.

6. Use tape to attach the ODDB thermocouple bead halfway up the cylinder to measure the temperature of the refrigerant.

7. Press T1-T2 / TSH / ODDB until ODDB is displayed.

Maintenance

Cleaning

• Wipe with a damp cloth to clean the exterior.
• Do not use solvents.

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 7 mL)
4. Cap off the VAC/center port and gently shake your SMAN while upside down to clean the 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.

Battery Replacement

• The batteries must be replaced when the battery life indicator is empty. Once the batteries are drained beyond operating voltage, “Low Bat” briefly appears and the manifold turns off.
• Unscrew the 4 cover screws and pull out the rear battery cover. Replace the 6 AA batteries and properly dispose of the old ones.

Using Different Refrigerants
You can use different refrigerants, but be sure to purge your manifold block and hoses with nitrogen before connecting to a system with a different refrigerant. Contamination can hurt system performance and cause damage.

2. Insert a thin shafted, Phillips screwdriver into the desired hose holder. Turn the screw counterclockwise to loosen and remove the 1/4” (brass color) hose holder. Take care to not damage or strip the screw head.
3. Replace the sealing o-ring with a new o-ring. Ensure that the o-ring does not block the threaded screw hole.
4. Insert the replacement hose holder and align it to the flats in the manifold block so that the bottom of the fitting is flush with the manifold block.
5. Insert a new screw into the replacement hose holder. Do NOT re-use the old screw. Use your screwdriver to securely tighten. The provided screws are pre-coated with a threadlocker. Do NOT overtighten.
6. Store the 1/4” hose holder in a safe and secure place for future use.

Pipe Clamp Storage Arm Replacement
Your pipe clamp storage arms can easily be replaced if they become damaged or capped if unused.

1. Lay your manifold face down on a non-abrasive, flat surface.
2. Using a Phillips screwdriver, loosen the screw by turning it counterclockwise.
3. Discard the damaged storage arm and screw.
4. Select the correct side replacement, or cap (LLT or SLT), and slide in to securely insert. Ensure it is flush with the manifold body.
5. Insert a new screw, use your screwdriver to securely tighten. Do NOT re-use the old screw. Do NOT overtighten.

Valve and Knob Replacement
If you are experiencing vacuum leaks through your valve(s), gauges are inaccurate, or there is physical damage, please complete the following to rebuild.

1. Lay your manifold face up on a non-abrasive, flat surface.
2. On the valve(s) you are replacing, pry, lift, and remove the knob’s label to expose the knob’s screw.
3. With a Phillips screwdriver, turn the screw counterclockwise to loosen and remove the knob. Do NOT re-use the old screw.
4. Using a 20 mm wrench, loosen the old valve by turning it counterclockwise. Once loose, pull straight up to remove.
5. On the replacement valve, apply a thin layer of silicone grease to the O-rings. Push the valve back in, tighten it by hand, and complete it with your wrench until tight. Do NOT overtighten. Use a threadlocker if desired.
6. Put on the new knob and twist until tight. Use the new screw and turn clockwise until tight onto the valve stem. Use a threadlocker if desired.
7. Stick on the correct replacement label depending on which valve you replaced.
8. Depending on how many valves you are replacing, repeat steps 2-7 as needed.
