 Common Safety Instructions for Vacuum Generator VG and VK Series

 Warning

Before selecting or using PISCO products, read the following instructions. Read the 
detailed instructions for individual series.

1.  For the operation of the valve, make sure that the leakage current is less than 

1mA. Leakage current larger than that may cause malfunction.

2.  The Vacuum Generator with retention function or check valve function permits 

some vacuum leakage, so provide an appropriate safety measure when vacuum 

retention for long period of time is required.

3.  Long continuous power supply to the valve may raise the temperature of the coil. 

Heat may cause damaging product life, malfunction, and burns or may adversely 

affect the peripherical machines. Consult PISCO about such applications.

 Caution

　1.  Do  not  give  an  excessive  tensile  strength  and  bending  on  a  lead  wire. 

Otherwise, breaking wire or damage on connector may be caused.

　2.  When  manifold  type  is  selected,  dropping  the  performance  or  having  an 

effect  to  other  vacuum  ports  can  be  caused  depending  on  number  of 

stations  or  a  combination  of  mounting  units.  Contact  us  for  any  unclear 

points.

　3. Compressed air contains many kinds of drains such as water, oxidized oil, 

tar and other foreign substances. Dehumidify the compressed air by using 

an  after-cooler  or  a  dryer  and  improve  the  air  quality,  since  those  drains 

seriously impair the performance of the vacuum generator.

　4. Do not use lubricators.

　5. Since pipe rust cause malfunctions, a filter finer than 5µm should be placed 

right before the air supply port.

　6. Do not use the vacuum generator under the condition of corrosive and/or 

flammable gases. Also do not use these gasses as a fluid medium.

　7. Do not operate blow-off solenoid valve during vacuum generating.

　8.  When  replacing  vacuum  port  cartridge,  first  remove  any  foreign  matter 

clinging  to  them  and  the  surrounding  areas,  then  firmly  insert  pins  into 

cartridges.

　9.  For handling and setting of vacuum switch, please read instruction manual 

carefully.

　10.  For  adjustment  of  vacuum  blow-off  air  flow  or  blow-off  time  of  air-timer 

operated blow-off valve on VK Series, read the instructions carefully.
