Series Specific roduct recautions Be sure to read this before handling the products. Refer to back page 5 for Safety Instructions and pages 49 to 51 for acuum Equipment recautions. Operation of Ejector alves Caution 1. When the air supply valve is turned ON, vacuum is generated by the flow of compressed air from the nozzle to the diffuser. When the vacuum release valve is turned ON, the vacuum is quickly released as air passes through the release flow adjustment needle and flows to the vacuum port. Caution Caution Operating Environment 1. void use exposed to direct sunlight. Solenoid alves (112 Series) 1. For specific product precuations on solenoid valves, refer to the Best neumatics No. 1-2.
