GB-75™ AND GB-152™ OPERATION AND MAINTENANCE MANUAL 

©1998-2008 DH Instruments, a Fluke Company 

 

  This equipment described in this manual is designed and manufactured for the intended purpose of 

generating high pressure gas.  Certain precautions need to be followed during installation and operation of this 
device.  Reading and understanding the material is essential to the safe and correct operation of the unit. 

 

  Pressurized equipment is potentially dangerous.  The equipment described in this manual generates and 

controls very high gas pressures.  It should not be operated by anyone who has not become thoroughly familiar 
with this manual.  Additional training in general and pressure specific safety procedures will help assure 
protection from harm or damage to personnel or property.  Responsibility for the proper and safe operation of 
this instrument rests with the user. 

 

 

High pressure liquids and gases are potentially hazardous.  Energy stored in these liquids and gases can 

be released unexpectedly and with extreme force.  High pressure systems should be assembled and operated 
only by personnel who have been instructed in proper safety practices.
