Activate Vacuum Alarms When Pulling a Vacuum
1 Press ALARM to activate low alarm. Default is 500 microns.
Stopwatch will start. When low alarm value is reached, SMAN460
will beep and the stopwatch will restart from zero. You can
monitor how long the vacuum has been under your target value.
2 Press ALARM again to deactivate low alarm and activate high
alarm. Default is 1000 microns. When high alarm value is
reached, SMAN460 will beep and the stopwatch will pause. You
can see how long it took to reach your target value.
3 Press ALARM again to deactivate high alarm.
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 "MegaFlow Valve 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 fittings 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.
Changing Units
Your SMAN can display pressure and temperature measurements
in English, Metric or combination of both units.
1 Press UNITS to enter unit selection screen.
2 Use ARROW to select your desired pressure units. Press ENTER.
3 Use ARROW to select your desired temperature units. Press ENTER
to return to pressure units.
4 Press UNITS to return to normal SMAN display.
Wireless System Analyzers
Your SMAN460 can connect with the Fieldpiece HVAC Guide® HG3
for deeper diagnosis, data storage and reporting. Send all your line
pressures and temperatures, vapor and liquid saturation temperatures,
superheat and subcooling calculations and micron readings wirelessly
to the Fieldpiece HVAC Guide® HG3.
1 Connect all hoses and pipe clamp thermocouples to the SMAN460
and the HVACR unit to be tested.
2 From main display, hold SYNC for 1 second until a beep is heard.
SMAN460 will begin searching for a Fieldpiece Wireless System
Analyzer.
3 Set your Fieldpiece HVAC Guide® HG3 to connect with the
SMAN460. Refer to your Fieldpiece HVAC Guide® HG3 manual for
more information on how to connect wirelessly.
Wireless Notes
1 The SMAN460 and Fieldpiece HVAC Guide® HG3 must be between
1 to 10 feet for initial sync to occur.
2 Be sure the Fieldpiece HVAC Guide® HG3 has been updated to the
latest firmware version located on our website.
Firmware Updates
Your SMAN460 firmware can be updated in the field to ensure you
always have the most up-to-date features for your manifold. Just go
to www.fieldpiece.com to periodically check for the latest firmware
version. If a newer version is available, follow the download link and
installation instructions on the website. Connect your SMAN460 to the
PC via a mini-USB to USB cable (not included) to install the update on
your SMAN.
To check your current firmware version, power off your SMAN460.
Press and hold the blue power button for about 6 seconds. The SMAN460
firmware version will show in the top right corner of the display (X.XX).

Auto Power Off (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 off. 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 the VAC port using
an eye dropper or funnel so that it can flush 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 Different Refrigerants
You can use your manifold with different refrigerants. Be sure to
purge your manifold and hoses before connecting to a system with a
different 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 field 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 flat 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, first 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.fieldpiece.com/support/downloads for newly added refrigerants
for the SMAN™ Manifolds via firmware update.
