Warning (1) Type of fluids

The operating fluid must be compressed air. Contact SMC if using the product with other fluids.

(2) When there is a large amount of condensate

Compressed air containing a large amount of condensate can cause malfunction of pneumatic equipment. An air dryer or water droplet separator should be installed upstream from filters.

(3) Drain flushing 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. This 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.

For compressed air quality, refer to SMC catalog "Compressed Air Purification System". (4) Types of air

Do not use compressed air which contains chemicals, synthetic oils containing organic solvents, salts or corrosive gases, etc., as this can cause damage or malfunction.

Caution (1) Install an air filter.

Install an air filter close to the upstream side of the valve. A filtration degree of 5mm or less should be selected.

(2) Install an aftercooler, air dryer or water separator etc.

Do not use compressed air containing a lot of condensate, which can cause failure of the flow control or other pneumatic equipment. Install an aftercooler, air dryer or water droplet separator.

(3) Use the product within the specified fluid and ambient temperature range.

When operating at temperatures 5oC or lower, water in the circuit may freeze and cause breakage of seals or malfunction. Measures should be taken to prevent freezing.

For the details of compressed air mentioned above, refer to SMC catalog "Compressed Air Purification System".

Warning (1) Do not use in an environment where

corrosive gases, chemicals, sea water, water or steam are present.

For materials of the flow control equipment, refer to their construction drawings.

(2) Do not expose the product to direct sunlight for an extended period of time.

(3) Do not operate in a location subject to vibration or impact.

(4) Do not mount the product in locations where it is exposed to radiant heat.

Warning

(1)Maintenance should be performed according to the procedure indicated in the Operation Manual. Improper handling can cause damage and

malfunction of equipment and machinery. (2) Maintenance operations If handled improperly, compressed air can be

dangerous. A knowledgeable and experienced person should perform assembly, handling, repair and element replacement of pneumatic systems.

(3) Draining Remove condensate from air filters regularly. (4) Removal of equipment, and supply/exhaust

of compressed air When components are removed, first confirm that measures are in place to prevent workpieces from dropping and/or equipment running away, etc. Cut the supply pressure and electric power and exhaust all compressed air from the system. Before restarting the equipment, confirm that measures are taken to prevent sudden movement.

Caution

(1) Connection and disconnection of tube from one-touch fitting

Insertion of tube

1) Cut the tube perpendicularly, being careful not to damage the external surface. Use SMC's tube cuter TK-1, 2 or 3 for cutting. Do not cut the tube with pliers, nippers, scissors, etc. This may flatten the tube and connection to the fitting may fail, causing disconnection of the tube and air leakage.

2) The outside diameter of polyurethane tubing swells when internal pressure is applied, so it may not be possible to re-insert used tubing into One-touch fittings. Confirm the outside diameter of the tubing. If the accuracy of the outside diameter is +0.07mm or more for 2, and +0.15mm or more for other sizes, insert into the one-touch fitting again without cutting it. When tubing is re-inserted into a One-touch fitting, confirm that the tubing is able to go through the release button smoothly.

3) Hold the tube and push it in slowly, inserting it securely all the way into the fitting.

4) After inserting the tubing, pull on it gently to confirm that it will not come out. If it is not installed securely all the way into the fitting, problems such as leakage or disconnection of the tube can occur.

Removal of the tube 1) Press the release button firmly. Push the collar

evenly around its circumference. 2) Hold down the release button while pulling out

the tube. If the release button is not held down fully, it will be more difficult to pull out the tube.

3) If the removed tubing is to be used again, cut off the section of the tubing which has been gripped. Re-using the gripped portion of the tube can cause problems such as air leakage or difficulty in removing the tube.

(2) Connection of the metal rod accessories Do not use tube, resin plug, reducer, etc. after connecting a fitting with a metal rod (KC series, etc.) to a One-touch fitting. This can cause the tube to disconnect.

(3) When mounting the tube, resin plug or metal rod, do not press the release button. Do not press the release button unnecessarily before mounting tubing, resin plugs and metal rods. This can cause the tube to disconnect.

Caution

(4) When using tubing from a manufacturer other than SMC, be careful of the tolerance of the tubing O.D. and tubing material.

1) Nylon tubing Within 0.1 mm 2) Soft nylon tubing Within 0.1 mm 3) Polyurethane tubing Within +0.15 mm,

Within -0.2 mm Do not use tubing which does not satisfy the specified tubing O.D. accuracy, or tubing with an I.D., material, hardness, or surface roughness that differs from SMC's tubing. Please consult SMC if anything is unclear. It may cause difficulty in connecting the tubing, leakage, disconnection of the tubing, or fitting damage.

(5)Tubing O.D.2

Tubing other than that from SMC cannot be used because it may result in the inability to connect the tube, air leakage after connecting the tube, or disconnection of the tube.

(1) When connecting piping to the One-touch fitting, use a pipe length with sufficient margin, in accordance with the piping conditions shown in Figure 1. Also, when using a tying band, etc., to bind the piping together, make sure that external force does not come to bear on the fitting.
