Pneumatic Clean Series

Clean One-touch Fittings KP537Specific Product Precautions 2Refer to pages 7 to 16 of Front matter for safety instructions and common precautions for clean series and pages512 and 513 for common precautions for fittings.wRemoval of tubing1) Push the release button deeply while also pushing in theflange equally.2) Pull out the tube while holding the release button so that itwill not pop out. If the release button is not pressedsufficiently, there will be increased biting force that willhinder the tube removal.3) When a disconnected tubing is used again, first cut off thebitten portion of the tubing. Use of a bitten portion of tubingwith no changes will result in air leakage or difficulty inremoving the tubing.Operating EnvironmentWarningqDo not use in environments or locations where there is adanger of damage to fittings and tubing. For fitting and tubingmaterials, refer to specifications and construction drawings,etc.wProvide shade in locations which receive direct sunlight.eDo not operate in locations where vibration or impact occurs.Since this can cause leakage and fitting damage, etc., contactSMC regarding use in this kind of environment.rBlock off heat radiation from a heat source in the proximity.If a heat source is located nearby, the temperature of theproduct may rise to exceed the operating temperature rangedue to heat radiation. Block off the heat source with a cover.tDo not use in locations where static electrical charges will be aproblem. Consult SMC regarding use in this kind ofenvironment.yDo not use in locations where spatter occurs. There is adanger of spatter causing a fire. Consult SMC regarding use inthis kind of environment.CautionqSeries KP is a line of special one-touch fittings for use in cleanroom blowing and washing lines. Consult SMC regarding othertypes of applications.Series KP is a line of special one-touch fittings for use in clean roomblowing and washing lines. Consult SMC regarding other types ofapplications.Use Series KPQ and KPG for piping to general pneumatic equipment.CautionqPre-maintenance inspectionWhen the product is to be removed, turn off the electric power,cut off the supply pressure without fail and confirm that fluid inthe piping has been discharged.wPost maintenance inspectionAfter remounting and connection of piping, restore the fluidand electric power, and perform suitable function and leaktests. If leakage occurs or the equipment does not operateproperly, stop operation immediately and confirm whether it ismounted correctly.eFurther tightening of blow fittings (resin taper threads for piping)Since Series KP taper threads are made of resin, minuteleakage may gradually occur due to stress relaxation. Performperiodic inspections, and if leakage is detected correct theproblem by further tightening. If additional tightening becomesineffective, replace the fitting with a new product.rConfirm the following items in periodic inspections and replacethe fittings or tubing as required.a)Scratches, gouge, wear, corrosionb)Consult SMC regarding fluids other than air, water orNitrogen gas.c)Twisting, twining and flattening of tubingd)Hardening, deterioration and softening of tubingtDo not use damaged or replaced fittings or tubing byreworking.Precautions on Use of Other BrandsCautionMaintenanceqWhen using tube brands other than SMC, confirm that theoutside diameter tolerances of the tubing satisfy the followingspecifications.1)Polyolefin tubing Within ±0.1mm2)Polyurethane tubing Within +0.15mmWithin –0.2mm3)Nylon tubingWithin ±0.1mm4)Soft nylon tubing Within ±0.1mmDo not use tubing if the outside diameter tolerance is notsatisfied. It may not be possible to connect the tubing, orleakage or disconnection may occur after connection.Polyolefine tubing is recommended for use with clean roomfittings. Note that while other types of tubing will satisfyperformance standards for leakage and tubing pull-outstrength, etc., the degree of cleanliness will deteriorate.518
