Product Specific Precautions 1 - SMC Networks XLF-2 Series Operation Manual

1. Product Specific Precautions 1

Precautions 1
Piping
Caution
1. Refer to the Fittings and Tubing Precautions on the SMC website for handling One-touch
fittings.
2. Before piping is connected, it should be thoroughly blown out with air (flushing) or washed to
remove chips, cutting oil and other debris from inside the pipe.
3. When connecting pipes, fittings, etc., be sure that chips from the
pipe threads and sealing material do not enter the valve.
Furthermore, when sealant tape is used, leave 1.5 to 2 thread
ridges exposed at the end of the threads.
Air Supply
Warning
1. Please consult with SMC when using the product in applications other than compressed air.
2. Compressed air containing a large amount of drainage can cause malfunction of pneumatic
equipment. An air dryer or water separator should be installed upstream from filters.
3. If condensation in the drain bowl is not emptied on a regular basis, the bowl will overflow and
allow the condensation to enter the compressed air lines. It causes malfunction of pneumatic
equipment. If the drain bowl is difficult to check and remove, installation of a drain bowl with
an auto drain option is recommended.
4. Do not use compressed air that contains chemicals, synthetic oils including organic solvents,
salt or corrosive gases, etc., as it can cause damage or malfunction.
Caution
1. When extremely dry air is used as the fluid, degradation of the lubrication properties inside
the equipment may occur, resulting in reduced reliability (or reduced service life) of the
equipment. Please consult with SMC.
2. Install an air filter at the upstream side of valve. Select an air filter with a filtration degree of
5 μm or finer.
3. Com pressed air that contains a large amount of drainage can cause malfunction of
pneumatic equipment such as valves. Therefore, take appropriate measures to ensure air
quality, such as by providing an aftercooler, air dryer, or water separator.
4. Ensure that the fluid and ambient temperature are within the specified range. If the fluid
temperature is 5
seals and equipment malfunction. Therefore, take appropriate measures to prevent freezing.
5. Moisture condensation can occur inside pneumatic systems due to a drop in temperature
caused by the piping or operating conditions. This can degrade or wash away grease,
resulting in shortened service life or malfunctions. For details, refer to the catalog
"Precautionary measures against condensation in a pneumatic system" (CAT.P-E01-11).
For compressed air quality, refer to the SMC catalog "Air preparation system".
Be sure to read before handling.
