Frequently asked questions

What other Fieldpiece wireless products connect wirelessly to the manifold?

The SM482VINT and SM382VINT are compatible and can connect wirelessly to the following: - JL3RH Psychrometer - JL3PC Pipe Clamp - JL3LC Large Pipe Clamp - SRS3 Weighing Scales - MG44 Vacuum Gauge - SR47 Weighing Scales

How do I clean my manifold?

Cleaning the Sensors in the manifold over time is required, the pressure sensors inside the manifold may become contaminated with dirt, oil, and other contaminants in normal operational use. To do so, please follow the guide below:

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 on the SM482VINT, or the central port on the SM382VINT.
3. Drop enough Isopropyl (rubbing) alcohol into the VAC/middle port using an eye dropper or funnel so that it can flush out contaminants.
4. Cap VAC/middle port and gently shake your Manifold 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. Repeat if necessary if issues persist.

Can I use the SM382VINT/SM482VINT with A2L and A3 refrigerants?

The manifold has a list of over 70 common refrigerants used in refrigeration and air conditioning, and this includes A2L and A3 refrigerants. For the full list of refrigerants visit the product page.

Why does my vacuum pressure jump up when I turn off my vacuum pump?

The moisture inside the system is still boiling off and is no longer being taken out or compensated for by the vacuum pump. There could be oil that is holding moisture inside either the hose leading to the manifold or inside the block of the manifold.

Why does my vacuum pressure jump up when I close my high side & low side?

You have isolated the micron gauge from the system, you are now only reading what is inside your manifold and the hose connected to vacuum pump.

What is the operating pressure range?

29" HgV to 870 psig/ 60 bar. 1-10.000 microns.

Why does my superheat/subcooling read -o/l?

You may have a negative degree of superheat or subcooling. To check this see below: ...................................................................................................................................................................................................................................................................................................................................................... 1. Plug in thermocouple into LLT port and change refrigerant to R113 to check to see if the manifold calculates subcooling. ...................................................................................................................................................................................................................................................................................................................................................... 2. Plug in thermocouple into LLT port and change refrigerant to R407F to check to see if the manifold calculates superheat.

Why is my vacuum pressure inaccurate?

Vacuum pressure being inaccurate is a sign of oil holding moisture either inside the block of the manifold or in the hoses. The oil in your vacuum pump may also need to be changed. Clean sensor periodically with rubbing alcohol.

How to perform advance pressure calibration?

Advanced Calibration: ...................................................................................................................................................................................................................................................................................................................................................... 1. Plug in thermocouple into SLT port. ...................................................................................................................................................................................................................................................................................................................................................... 2. Calibrate Thermocouple to Ice water 0°C. ...................................................................................................................................................................................................................................................................................................................................................... 3. Tape thermocouple to side of refrigerant tank that has been sitting at a constant temperature for 24-48 hours. ...................................................................................................................................................................................................................................................................................................................................................... 4. Put a brass cap on SLT and another one on LLT and open up both valves. ...................................................................................................................................................................................................................................................................................................................................................... 5. Hook up refrigerant tank to manifold and open the tank. (Ensure that the Vac valve is closed on manifold before opening refrigerant tank. 4 port manifold only.) ...................................................................................................................................................................................................................................................................................................................................................... 6. Open refrigerant tank. ...................................................................................................................................................................................................................................................................................................................................................... 7. Select the type of refrigerant being used for this on the manifold. ...................................................................................................................................................................................................................................................................................................................................................... 8. Open up the Ref port on manifold (4 port manifold only). Both high and low pressures should read the same. ...................................................................................................................................................................................................................................................................................................................................................... 9. Press “Test Cal” button. Both pressure sensors should read “GOOD”."

What is the wireless range?

300 meters line of sight.

Which refrigerants are compatible with the SM382VINT & SM482VINT manifolds?

A full list of refrigerants can be found in our user manual, under specifications. Additional refrigerants can be uploaded to the manifold via regular software updates. Check our Software Update page on the website.

How many wireless tool can I connect to my Digital Manifold at the same time?

The SMAN® refrigerant manifold can connect to multiple Job Link® tools and display those values on the screen of the manifold. The number of tools that can be connected at the same time are: 3 x JL3RH Psychrometer 2 x JL3PC Pip Temperature Clamps 2 x JL3LC Large Pipe Temperature Clamps 1 x MG44 Vacuum Gauge 1 x SRS3 or SR47
