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. In addition to the included thermocouples, you can connect wirelessly to psychrometers, pipe clamps, and even a refrigerant scale. For example, assign one psychrometer (model JL3RH) to return air and another to supply air to view live temperature split across the evaporator directly.

View all your measurements and live calculations on the extra large LCD or from a distance on your mobile device. A rolling list of your 10 most recently used refrigerants is stored at the top of the main refrigerant list for quick selection.

Verify proper charge by comparing actual superheat (SH) with target superheat (TSH). Use the outdoor dry bulb thermocouple and an optional indoor psychrometer for live TSH calculations.

Pressure sensors automatically compensate for altitude and weather changes. Use the internal vacuum gauge for fast and convenient monitoring of your evacuations.

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. Fully plug pipe clamp thermocouples into SLT and LLT rear jacks.

5. Hand tighten both the LOW side hose to 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 system has stabilized before using superheat or subcooling to

adjust the charge of the system.

• To add or remove refrigerant connect the tank/cylinder/machine to

the center refrigerant port. Use manifold valves to precisely charge

or recover refrigerant as needed. Follow recommended charging or

recovery practices from equipment manufacturer 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 (page 26). ODDB: By default, this is the live measurement of the ODDB

thermocouple jack. If you prefer a static measurement, assign a

manual value (page 27).

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. Press VIEW until ODDB is displayed to verify the measurement.

If you changed ODDB to a manually set value, it will be used to

calculate TSH but will not be displayed.

3. Measure IDWB after the ﬁlter, just in front of the indoor coil. If

a psychrometer is assigned, you can press AIR until wet bulb is

displayed to verify the measurement.

4. Press VIEW until TSH is displayed.

1716

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. Open shutoﬀ valve between pump and manifold.

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 ALARM to activate the low alarm.

The stopwatch starts. The rate of change is displayed in units

per minute. The smaller the rate of change, the closer you are to

stabilization. You may need to improve your setup if rate slows well

before reaching your desired vacuum (see Tips for Better Evacuations).

7. Once the the low alarm level is reached, the backlight blinks and

alarm sounds. Press any button (other than ENTER) to silence alarm.

8. Close shutoﬀ valve 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 ALARM to activate the high alarm and start the stopwatch.

11. Once the high alarm level is reached, the backlight blinks, alarm

sounds, and the stopwatch stops. Press any button (other than

ENTER) to silence alarm.

12. Close HIGH and LOW manifold valves.

The vacuum sensor is now blocked from the system (page 39).

Tips for Better Evacauations

• Remove schrader cores and depressors with a core removal tool.

• Use shortest vacuum rated hoses with largest diameter available.

• Do not evacuate through hoses with low loss ﬁttings.

• Inspect the rubber seals at both ends of your hoses for damage.

• Change pump oil before and during the job. Change pump oil onthe-ﬂy without losing 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 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.

1918

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. 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 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.

To deactivate temperature compensation, unplug or unassign SLT

before starting the test; SLT will not be shown or used.

4. Press TEST TIGHTNESS to prepare test.

5. Press ENTER to start the test.

The stopwatch starts.

Real-time compensated pressure change is labeled P.diF.

Real-time temperature is labeled SLT.

Real-time temperature change is labeled ΔT.

6. Press ENTER to stop the test.

The stopwatch, P.diF, and ΔT freeze.

If P.diF is negative, there may be a leak in the system.

If P.diF 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 ENTER to exit the test.

Test for Noncondensables

If head pressure seems high even after cleaning coils, optimizing airflow, and other routine maintenance, you may have noncondensables trapped in the system. Noncondensables can reduce eﬃciency, performance, and put extra stress on system components. Noncondensables can enter the system in many ways, and your initial system service may be following years of poor service that introduced the noncondensables.

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 noncondensables are trapped.

Depending on the system, a negative SC may suggest a need to

recover, evacuate, and charge with virgin refrigerant.

• 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.

Temperature Calibration

Thermocouples (T/C) are not calibrated directly. Instead, each T/C jack (ODDB, SLT, LLT) must be calibrated to the particular T/C that is plugged into it. Though it’s possible for a calibration to 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 probably the most accurate and readily available known temperature (32.0°F, 0.0°C) in the ﬁeld.

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 (SLT,

LLT, or ODDB).

4. Press ENTER 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) in order to help prevent mistakes.

6. Press ENTER 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 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. Leaving the cylinder in the same place it was left to stabilize,

connect the cylinder to either the HIGH or LOW side port.

4. Cap the 2 unused ports.

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 VIEW if ODDB is not shown.

8. Open both HIGH and LOW side manifold valves.

9. Open the refrigerant cylinder valve.

The pressure inside cylinder should now be displayed on both HIGH

and LOW side pressure sensors.

10. Allow the pressure readings and ODDB temperature to stabilize.

11. Press MENU.

12. Use ARROWS to show Adv Pressure Cal.

13. Press ENTER to initiate calibration of the pressure sensors.

14. Each pressure sensor will brieﬂy display “Good” if successful or “Err”

if unsuccessful, then return to normal operating mode.

Troubleshooting an “Err” message

1. Measured pressure was less than 10 psig.

• Refrigerant cylinder may be nearly empty.

• Valves may be closed.

2. Measured pressure was not within ±3psig of VSAT pressure on the P-T chart.

• Thermocouple may not have been calibrated properly.

• Thermocouple may not have been attached properly to cylinder.

• Thermocouple may have not been connected to ODDB jack.

• Refrigerant cylinder pressure was unstable.

• Refrigerant cylinder temperature was unstable.

• Refrigerant selected did not match refrigerant in cylinder.
