Page 40: Detailed Safety Instructions
Caution 1. In case that not all units generate vacuum at same time, the exhaust air of operating unit flows into the vacuum port of non-operating unit. If such exhaust air causes the problem, please consult with PISCO. - Page 41 Safety Rules for Use ■ Operating temperature range is 5-50℃ . Do not operate the product out of the temperature range. ■ Compressed air contains many kinds of drains such as water, oxidized oil, tar and other foreign substances. Dehumidify and improve the quality of air by using an after-cooler or a dryer, since those drains seriously impair the performance of the vacuum generator.

JIS B 8370：General rules and safety requirements for systems and their components. This safety instructions is classified into “Danger”, “Warning” and “Caution” depending on the degree of danger or damages caused by improper use of PISCO products. Danger Hazardous conditions. It can cause death or serious personal injury. - Page 46 PISCO products, or by combinational use with non-PISCO products and other software systems. 5. The damages caused by the defect of Pisco products shall be covered but limited to the full amount of the PISCO products paid by the customer.
- Page 47 2. Do not disassemble or modify PISCO products, which affect the performance, function, and basic structure of the product. 3. Turn off the power supply, stop the air supply to PISCO products, and make sure there is no residual air pressure in the pipes before maintenance and inspection.
- Page 48 When a fluid medium is liquid or the products are required to be used in harsh environments, contact us for further information. 5. In case of using non-PISCO brand tubes, make sure the tolerance of the outer tube diameter is within the limits of Table 1.

- Page 50 Series Vacuum Generator Common Safety Instructions for Vacuum Series Before selecting or using PISCO products, read the following instructions. Read the detailed instructions for individual series. Warning 1. If there is a risk of dropping work-pieces during vacuum suction, take a safety measure against the falling of them.
- Page 51 2. Effective cross-section area of the air supply side needs to be three times as large as effective cross-section area of the nozzle bore. When arranging piping or selecting PISCO products, secure required effective cross-section area. Insufficient supply pressure may be a cause to impair performance.
