(11) Please connect a pump to a power supply. Please attach an appropriate terminal to an 

installation  terminal  stand  surely  by  all  means.  It  causes  the  electric  shock.  Please 

perform  wiring,  setting  construction  according  to  use  local  laws  and  ordinances,  safety 

requirements. A green insulation coated electric wire is a ground with or without a yellow 

stripe. 

(12) When take off the power supply cord of the pump, turn off a device main power supply 

by  all  means,  and  please  exclude  a  code  from  a  terminal  stand.  It  causes  the  electric 

shock. 

(13) Touching the power cord with wet hands may result in electric shock. 

(14)   Touching electrical wiring etc while inserting the power cord may result in electric shock. 

(15) Do not remove the cover of capacitor, it causes the electric shock. 

 

Operation 

(16) This pump is not designed to be explosion-proof, and should therefore not be used in the 

vicinity  of  inflammable  substances  (e.g.  inflammable  solvents)  or  in  explosive 

atmospheres. Failure to follow these requirements may result in injury or fire. 

(17) Inserting fingers or objects into the motor inlet may result in electric shock, injury, or fire. 

(18) Operating  the  pump  with  the  discharge  outlet  blocked,  or  with  a  device  which  prevents 

passage  of gas to the  discharge  outlet, may  result  in  rupture  of the  pump.  The  internal 

pressure  of  the  pump  rises  and  the  pump  body  may  rupture  and  the  motor  become 

overloaded. This pump is not designed to be pressure-resistant. The internal pressure of 

the pump is limited to 0.03 MPa (gauge pressure). 

Maintenance and Repair 

(19) The  pump  should  be  dismantled  or  repaired  only  by  a  repair  technician  trained  by  the 

manufacturer.

 

 

(20) To prevent ingestion of microscopic particles resulting from wear of components, 

use a dust mask and gloves when replacing cup packing, inlet and outlet valves, and 

gaskets.

 

 

 

Installation 

(1)   Microscopic particles resulting from wear of components are discharged from the outlet and 

contaminate the room. If necessary, connect a pipe from the discharge outlet to the outside of 

the building. 

  (2) The  fine  clearances  used  in  this  pump  require  that  the  following  conditions  be  satisfied 

during storage, installation, and operation. 

 1.

 

Ambient temperature during operation : Ambient temperature range of product 

specification .(refer to table1-1)                                                        [Continued on next page]
