<Operation> 

(14)   This  pump  is  not  designed  for  explosion-proof  construction.  Do  not  use  the  pump  near 

inflammables such as flammable solvent and in explosive atmosphere.    There is a risk of injury 

or fire. 

(15)   Do not insert a finger and substances into opening of the motor. There is a risk of electric shock, 

injury and a fire. 

(16)   There is a risk of rupture. Do not operate the pump in the status that exhaust vent is blocked or 

mounting  equipment  that  hinder  gas  passage  in  the  exhaust  vent  side.  Increased  internal 

pressure of the pump may cause rupture of the main unit of the pump or overload to the motor. 

This  pump  is  not  designed  for  pressure  withstanding  construction.  Threshold  value  of  pump 

internal pressure is 0.03 MPa (gauge pressure). 

<Maintenance / repair>

 

(17)   Do not allow other personnel than 

repair engineers

 

*

to disassemble or repair the pump. 

* 1 Repair engineers: Those who are trained by ULVAC technical training. 

(18)   Wear  dust  mask  and  gloves  when  conducting  replacement  work.  A  minute  abrasive  particle 

suspends in the air, and there is a risk to go into the human body when breathing.

 

 

 

 

<Installation> 

(1)    This  pump  is  a  machine  having  precise  clearance.  Satisfy  the  following  requirements  when 

conducting storing, installation and operation 

 

1.    Operation temperature and the humidity 

0

 to 40

 in temperature, Lower than 85% 

(relative humidity) in humidity 

2.    Others (applicable both storing and operation) 

a.   

Level location where enough floor strength. 

b.   

No condensation. 

c.   

No dust. 

d.   

Well ventilated indoor. 

e.   

No explosive gas. 

f.   

No direct sun rays. 

g.   

No flammability risk. 

h.   

When  Equipment  is  installed,  temperature  in  pump  circumference  shall  not  exceed 
40

   

(2)    There  is  a  risk  of  hurting  lower  back.  Lift  the  pump  with  both  hands  definitely  to  move  and     

conduct work. 

(3)    Abrasive particles of diaphragm may drain from the exhaust vent and pollute the room. Exhaust 

it to out of the chamber by connecting pipes if necessary. 

<Operation> 

(4)    Please do not use it to application coming in contact with human body transplant and body fluid / 

a living body organization. 

(5)    Definitely do not touch the rotating section such as a motor, main spindle, coupling, cooling fan 

while driving the pump. There is a risk of injury.
