Your SMAN allows you to input indoor wet bulb (IDWB) and outdoor dry bulb (ODDB) temperatures manually, in real-time using K-type thermocouples, or a combination of both to calculate the Target Superheat. Your SMAN will detect if a thermocouple is plugged in or not. Unplugging the thermocouple lead(s), at any time, sends the SMAN into manual input mode and plugging them in, at any time, automatically sends the SMAN to input directly from the thermocouples. Saturation Shows vapor (VSAT) and liquid (LSAT) saturation temperatures calculated from the pressures measured and the refrigerant selected. 07 CAL CAL CAL Test Pressure Test Pressure Test Pressure Test Pressure AUTO OFF CAL 1 Press circular button to cycle through temperature modes until SH and SC are shown. The SMAN can show superheat and subcooling simultaneously. 2 Choose the appropriate refrigerant using the REFRIGERANT button. 3 Connect the K-type thermocouple and EPA approved refrigerant hoses to your SMAN. 4 Connect your SMAN to the system: Superheat: Hand tighten low side hose to suction line service port. Place the thermocouple on the suction line between the evaporator and compressor, no closer than 6 inches to compressor. Subcooling: Hand tighten high side hose to liquid line service port. Attach the thermocouple on the liquid line between the condenser and expansion valve (TXV), as close to the service port as possible. 5 After turning the system on or making any adjustments to the system wait 15 minutes before charging by superheat or subcooling to ensure that the system is stable and running normally. Add or remove refrigerant using the low and high side valves as needed. Let system stabilize again for 15 minutes. HIGH CAL CAL Superheat and Subcooling Saturation LOW 1 Press circular button until T1 and T2 are shown. 2 Plug in any K-type thermocouple into T1 and/or T2. 3 Read the temperature directly from the display. 1 Connect your SMAN to the system using EPA approved 1/4in refrigerant hoses. 2 Read pressures directly from the upper display. 14 CAL T1 T1 T1 T2 Direct Standard Pressure 1 7 11 T1 T2 Direct LOW 03 08 Input temperatures with K-type thermocouples 1 Press circular button until Target SH is shown in the bottom, center of display. 2 Plug ATWB1 Wet bulb K-type thermocouple into T1 and ATA1 Dry bulb K-type thermocouple into T2. 3 Press ENTER. The IDWB will display the real-time temperature measured from T1. Use the ARROW button to select the temperature you want to input first, either IDWB or ODDB. 4 For IDWB input, wet the sock of the ATWB1. Clip it to the return of the evaporator between the filter and coil. When the wet bulb temperature reaches its lowest point and stabilizes, press ENTER to lock the reading. If the inputted temperature is below the wet bulb range, “-OL” will blink. If the inputted temperature is above the wet bulb range, “OL” will blink. Retake the measurement if “OL” or “-OL” is displayed.

Why Do I Need to Measure It? 11 Superheat is the difference between the actual temperature of the refrigerant (gas) as it leaves the evaporator and the boiling point of the refrigerant. After boiling, the refrigerant continues to heat up. The number of degrees it “heats up” after boiling is called the superheat. Under worst case conditions (low load for fixed orifice systems), the refrigerant in the evaporator boils off near the end of the evaporator coil. To make sure liquid doesn’t enter the compressor under the worst case condition (low load), the refrigerator or A/C manufacturers publish charts indicating what the superheat should be at a given indoor wet bulb measurement and outdoor air temperature. Measuring superheat is your best indication on a fixed orifice system of the proper refrigerant charge and operating conditions. If everything else is working properly and the actual superheat is too high, add refrigerant. If it’s too low, evacuate refrigerant. Subcooling is the difference between the boiling point of the refrigerant in the condenser and the actual temperature of the refrigerant Low Side High Side 12 Location of Subcooling Test Location of Superheat Test 13 Advanced Pressure Calibration Temperature To calibrate your SMAN temperature thermocouples, adjust the pot on the front of the meter labeled T1 Cal or T2 Cal. The best way to calibrate is to match to a known temperature. Ice water is very close to 32°F and is readily available. Accuracies of one degree or better are easily obtained. Note: If the P1 and P2 pressure readings are not at zero, perform a Pressure Zeroing adjustment before performing this advanced calibration. 1 Press circular button until your SMAN enters T1 T2 Direct mode. 2 Plug in a K-type thermocouple into T1. (A bead type thermocouple, like the ATB1, is recommended.) 3 Connect the SMAN to a refrigerant cylinder of a known, single refrigerant using an EPA approved service hose. Be sure to open both HIGH and LOW side valves on your manifold and cap the unused ports. (If caps are not available you can connect both ends of a refrigerant hose to the two unused caps. Note you will lose some refrigerant into the hose using this method.) 4 Press the REFRIGERANT button to match the refrigerant of the cylinder you are using. 5 Attach bead-type thermocouple to the side of the cylinder using tape. It is recommended to attach in the middle of the cylinder. Important: Let the temperature of the thermocouple stabilize to the refrigerant temperature for 1 to 2 minutes or until stable. Note: For best results, the refrigerant cylinder should have been stored in a stable ambient condition environment for at least 24 hours. 6 Open the refrigerant cylinder. The pressure inside cylinder should now be displayed on both HIGH and LOW side pressure sensors. 7 Press the CAL Test Pressure button. 1 Stabilize a large cup of ice water by stirring. Pure, distilled water will be the most accurate. 2 Press the circular button until your SMAN enters Direct Temperature (T1 T2) mode. 3 Immerse the temp probe in ice water from T1 and adjust the T1 Cal pot with a flathead screwdriver and let it stabilize, keep stirring. 4 Repeat Step 3 for temp probe in T2. Pressure Zeroing To calibrate your SMAN pressure sensors to atmospheric pressure, ensure that your SMAN is disconnected from any pressure source and at equilibrium with the ambient pressure. 1 SMAN must be in Superheat/Subcooling, Saturation, or T1 T2 Direct mode. 2 Press the CAL Atmospheric Pressure button and your SMAN will set the zero point of pressure to the ambient pressure. Cleaning the Sensors (SMAN3) Over time, the vacuum sensor of the SMAN3 may become contaminated with dirt, oil, and other contaminents introduced from pulling vacuums. The P-T charts of the following refrigerants come pre-programmed into your SMAN. In your SMAN the refrigerants are listed in order of most commonly used. Here, they are listed in numerical order for easy reference. R11, R113, R114, R12, R123, R124, R125, R13, R134A, R22, R23, R401A(MP39), R401B, R402A, R402B, R404A, R406A, R407A, R407C, R408A, R409A, R410A, R414B (Hotshot), R416A, R417A, R420A, R421A, R421B, R422A, R422B(NU22B), R422C(Oneshot), R422D, R424A, R434A(RS-45), R438A(MO99), R500, R502, R503, R507A 1 Never use an object such as a cotton swab to clean the sensor, you may cause damage to the sensor. 2 Open all knobs/valves, and cap all the ports except for the center port. 3 Drop enough Isopropyl (rubbing) alcohol into the uncapped port using an eye dropper or funnel so that it can flush out contaminents. 4 Cap central port and gently shake your SMAN upside down to clean sensor. 5 Turn right side up. Open a port to pour out the rubbing alcohol and open all ports to allow sensors to dry out; usually an hour or so. 15 Limited Warranty Obtaining Service This meter is warranted against defects in material or workmanship for one year from date of purchase.

The degrees that the refrigerant “cools down” below the boiling point is the subcooling. Under worst case scenario (low load for TXV) the subcooling will continue to rise. If the subcooling rises too high, liquid may be backed into the compressor causing damage and catastrophic failure. See www. fieldpiece.com for more technical articles.
