WARNINGS

Do not apply more than 800 psig to any port of the manifold.

Ground properly when testing A2L/A2/A3 (hydrocarbon) refrigerants.

Do not use in the vicinity of explosive substances.

Inhalation of high concentrations of refrigerant vapor can block oxygen to

the brain causing injury or death.

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 SM480V 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.

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 REF port. Use the 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.

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.

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 VAC port to vacuum pump.

3. Turn on your vacuum pump.

4. Open VAC 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 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 VAC 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 on-

the-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.
