     Note) The display window of the element service indicator of semi standard products is made of nylon.

4. For air blow applications, prevent airborne particles from the operating environment entering into the compressed air stream, or foreign matter may adhere to the workpiece during the air blow.

5. If the air equipment is mounted on the outlet of the product, particles will be generated from the equipment and required cleanliness may not be obtained. Instead, install the air equipment at the inlet.

Caution

1. Applications in which the difference between the inlet and outlet pressure exceeds 0.1MPa must be avoided. Or the element is broken.

Selection

Warning

1. Grease is used on the internal sliding parts and seals. The grease may flow to the outlet side. If this is not acceptable, please consult SMC.
2. Select the model so that the maximum discharge value (instantaneous) of the flow rate will not exceed the rated air capacity. If the flowrate exceeds the maximum air flow capacity, it may cause spillage of drainage and oil to the outlet side, and damage equipment downstream.
3. N.O. type auto drain should be operated under the following conditions to avoid operating failure. Operating compressor: 0.75kW or more. Discharged flow rate: 100L/min (ANR) or more. When using 2 or more auto drains, multiply the value above by the number of auto drains to find the capacity of the compressors you will need. For example, when using 2 auto drains, 1.5kW (200L/min (ANR)) of the compressor capacity is required. The operating pressure should be 0.1 MPa or more.
4. Use the N.C. type auto drain at the operating pressure of 0.15MPa or higher to prevent malfunction.

Caution

1. Do not use the product with low air pressure (e.g. for blower). This product is dedicated for compressed air whose minimum operating pressure is specified depending on the equipment. If the product is operated at a pressure lower than the minimum operating pressure, it may cause deterioration in the performance or malfunction.

Installation

Warning

1. Do not drop or apply impact during transportation or installation. It will cause damage to the product and result in operation failure.
2. Do not install in areas of high humidity or high temperature. Operation outside of the product specification range may cause damage to the product or operation failure, or shorten the product life.
3. Connect the product ensuring the direction of arrow or “1”(IN) and “2”(OUT) ports for air direction or an arrow. Incorrect connections may cause malfunction.
4. Install with adequate space for maintenance beneath the product. Refer to [12. Dimensions] (page

19. for necessary space.

5. Install vertically so that outlet of drain is facing downward. It cannot be used in horizontal or upward direction as it may cause operation failure.

Piping

Warning

1. Before piping, perform flushing or cleaning of the piping, etc. to remove any cutting chips, cutting oil, solid foreign matter, etc. from the piping. Contamination of piping may cause damage or malfunction.
2. When screwing together pipes and fittings, etc., be certain that chips from the pipe threads and sealant do not get inside the pipe. When a sealant tape is used, leave 1.5 to 2 thread ridges exposed at the end of the threads.
3. Connect piping/fittings using the recommended torque while holding the female thread side tightly. Insufficient tightening torque can cause loose piping or sealing failure. Excess tightening torque may cause damage to threads. If the female side is not held while tightening, excessive force will be applied to the bracket directly, causing breakage.
   Recommended tightening torque (Unit: N m)Thread size| 3/4| 1
   ---|---|---
   Torque| 28 to 30| 36 to 38
4. Before screwing-in an SMC fitting or S coupler, please refer to “Tightening the threaded portion of the connection thread” section of the Fitting & Tubing Precautions.
5. Do not apply torsion or bending moment other than the weight of the product itself. External piping needs to be supported separately as it may cause damage. Non-flexible piping like steel tube is susceptible to excessive moment load or vibration. Insert flexible tubes to prevent this.
6. Drain guide is not equipped with valve function. Be sure to connect piping for drain. No piping for drain allows the drain and compressed air to exhaust freely. Also, the piping should be performed with drain guide held by spanner to prevent breakage of bowl.
7. To make drain discharge piping for auto drain, connect pipes under the following conditions to avoid malfunction. Tube with a piping internal diameter of ø6.5 (ø1/4″) or above and a length of 5 m (200 inch) or less.
8. Pipework for auto drain discharge which rises higher than the auto drain outlet should be avoided. It may cause the auto drain operation to fail.

Air Source

Warning

1. Use clean air. Do not use compressed air containing chemicals, organic solvent, synthetic oil or corrosive gas as it may be cause of breakage of components or operation failure.
2. Air containing too much moisture may deteriorate the performance. Install the refrigerated air dryer or aftercooler before the line filter.
3. Make sure that the supply pressure is not below the minimum operating pressure. If it is used at the minimum operating pressure or less, pressure resistance increases, leading to the decrease of operation life or operation failure.

Maintenance

Warning

1. Release the pressure in the product to the atmosphere when replacing parts or removing piping.
2. Maintenance and checks should be done by following the procedure in the operation manual. Incorrect handling of the product may cause breakage or operation failure of the equipment or device.
3. Do not touch the product when operating at high temperature (40 to 60 oC). The operators may get burnt. Be sure to confirm that the temperature of the container or operating part is reduced to 40 oC or less to prevent burns.
4. On a product with an element service indicator, perform regular checks to find cracks, scratches, or other deterioration of the indicator window. If any crack, scratch, and other defect is observed, replace the element service indicator with new a one because such a defect may cause the product to be broken. Investigate and/or review the operating conditions if necessary.
5. Check for dirt in the bowl periodically. If any dirt is seen, replace with new bowl.
6. Open and close drain cock by hand. The use of tools can result in damage to the product.
7. Replace the element before 2 years passed from start of use or pressure drop (difference between the inlet pressure and outlet pressure) reaches 0.1MPa. Or if the element is broken.

Caution

1. Check the element periodically and replace it with a new one if necessary. If it is found that outlet pressure drops or the flow is restricted, check the condition of the element.
2. For the N.C. type auto drain, when there is no pressure, condensate which does not operate the auto drain mechanism will remain in the bowl. It is recommended to release the residual condensate manually at the end of the working day.
3. Products with an element service indicator show a red indication as the element clogging progresses. Ensure that the element is replaced before the red indication reaches the upper limit.

Application

This product aims at eliminating excess saturated water and solid foreign matter in the air line.
