Superheat and Subcooling
Your SMAN460 can calculate and display both superheat and
subcooling simultaneously.
1 Select the appropriate refrigerant using the REFRIGERANT button.
2 Connect EPA approved refrigerant hoses to low and high side on
SMAN460. Plug Type K thermocouple pipe clamps to SLT and LLT.
3 Connect your SMAN460 to the system:
Superheat: Hand tighten low side hose to suction line service
port. Place the SLT pipe clamp 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 LLT pipe clamp thermocouple on the liquid line
between the condenser and expansion valve (TXV), as close to the
service port as possible.
4 After turning the system on or making any adjustments to
the system wait 15 minutes before charging by superheat or
subcooling to ensure the system is stabilized.
5 To add or remove refrigerant connect a refrigerant or recovery
cylinder to the REF port on SMAN460. Follow recommneded
charging or recovery practices from equipment manufacturer. Use
the low side, high side, and REF valves on SMAN460 to charge or
recover refrigerant as needed. Let system stabilize for 15 minutes.
Note: When superheat and/or subcooling cannot be calculated an
"OL" or "-OL" will be displayed. Please check the following:
1 The correct refrigerant is selected on the SMAN.
2 The pipe thermocouples are plugged into SLT/LLT ports and are in
good working condition.
3 The pipe thermocouples are attached in the appropriate location on
the system. See step 3 above for details.
Target Superheat
Target Superheat is useful for charging xed orice air conditioning
systems. Your SMAN460 can receive real-time indoor wet bulb (IDWB)
and outdoor dry bulb (ODDB) temperatures wirelessly to calculate real-
time target superheat.The IDWB and ODDB values can also be entered
both manually if measurements are taken by other instruments, or a
combination of one wireless measurement with one manually inputted
measurement.

Additional Evacuation Tips to Reach a Deeper Vacuum:
1 Use shortest vacuum rated hoses with largest diameter available.
2 Remove schrader cores and core depressors. Core removal tools
like the "MegaFlowValve Core Removal Tool" can be purchased
from Appion, Inc. to help with this process.
3 Inspect the rubber seals at both ends of your hoses for damage
that may result in leakage.
4 Do not use hoses with low loss ttings when evacuating or
pulling a vacuum on a system.
5 When the vacuum pump is isolated from the system, a slow rise
in micron levels may signify moisture is still present in the system
but should eventually stablize. A continuous rise in microns levels
to atmosphere may indicate a leak in the hoses, the vacuum
pump connections or the system.

Auto Power O (APO)
To conserve battery life, your SMAN will power down after 30
minutes of inactivity. APO is activated by default and APO displays
above the battery icon. To deactivate, press and hold ENTER while
powering on the SMAN. When deactivated, APO will no longer show
above the battery icon.
Maintenance
Clean the exterior with a dry cloth. Do not
use liquid.
Battery Replacement
The battery must be replaced when the
battery life indicator is empty. SMAN will
display "lo batt" and power o. Remove rear
battery cover and replace with 6 AA batteries.
Cleaning the Micron Sensor
Over time, the vacuum sensor of the SMAN460
may become contaminated with dirt, oil, and
other contaminants from pulling vacuums.
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.
3 Drop enough Isopropyl (rubbing) alcohol into theVAC port using
an eye dropper or funnel so that it can ush out contaminants.
4 Cap VAC port and gently shake your SMAN460 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. Drying usually
takes about an hour.
Using Dierent Refrigerants
You can use your manifold with dierent refrigerants. Be sure to
purge your manifold and hoses before connecting to a system with a
dierent refrigerant.
Calibration
Temperature
To calibrate your SMAN460 temperature
thermocouples, adjust the pot on the front
of the meter labeled SLT Cal or LLT 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 obtained through eld calibration.
1 Stabilize a large cup of ice water by stirring. Pure, distilled water
will be the most accurate.
2 Immerse the temp probe in ice water from SLT and adjust the
SLT Cal pot with a at head screwdriver and let it stabilize, keep
stirring.
3 Repeat Step 2 for temp probe in LLT.
Pressure Zeroing
To calibrate your SMAN460 pressure sensors
to atmospheric pressure, ensure that your
SMAN460 is disconnected from any pressure
source and at equilibrium with the ambient
pressure.
1 Press the CAL Atmospheric Pressure button and your SMAN460
will set the zero point of pressure to the ambient pressure.
Advanced Pressure Calibration
Your SMAN460 has the ability to perform a
linear adjustment of the pressure sensors based
on refrigerant type, temperature, and pressure.
Calibration setup: For best results, rst perform both the
Temperature and Pressure Zeroing procedures. See Calibration
section for details. This will ensure pressure readings are zeroed
and thermocouple is properly calibrated to the SLT port of the
SMAN. Calibration to LLT port is not necessary for this calibration.
The refrigerant cylinder should be stored in a stable ambient
environment for at least 24 hours before calibration.
1 Plug in a Type K thermocouple into SLT. (A bead type
thermocouple, like the ATB1, is recommended.)
2 Connect the SMAN460 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:
Some refrigerant will remain in the hoses which will need to be
recovered.)
3 Press the REFRIGERANT button to match the refrigerant of the
cylinder you are using.
4 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.
5 Open the refrigerant cylinder.The pressure inside cylinder should
now be displayed on both HIGH and LOW side pressure sensors.
6 Press the CAL Test Pressure button. If successful, "Good" will
display for 3 seconds. If failed, "Err" will display for same time.
Your SMAN checks with its built-in P-T charts to compare the
temperature of the refrigerant in the tank to the vapor saturation
temperature based on the refrigerant you selected. If the measured
pressures on your SMAN are within ±3psi of the P-T chart pressure
corresponding to the vapor saturation temperature, the SMAN will
adjust the pressure sensor linearity to match the P-T chart.
Possible causes of failed "Err" pressure calibration:
1. Refrigerant tank was not stored in stable ambient conditions for at
least 24 hours.
2. Thermocouple attached to refrigerant tank was not properly
calibrated to SLT port of SMAN.
3. Thermocouple was plugged into wrong port LLT instead of SLT.
4. Incorrect refrigerant was selected on the SMAN.
Refrigerants
The P-T charts of the following 45 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.
Periodically we program new refrigerants in SMAN™ Manifold, go to
www.eldpiece.com/support/downloads for newly added refrigerants
