Safety

 

 
Instrutech has designed and tested this product to provide safe and reliable service, provided it is installed and 
operated within the 

strict safety guidelines provided in this manual

.

  Please read and follow all warnings and 

instructions.   Failure to comply with these safety procedures may result in serious bodily harm, including 
death, and or property damage.

  Failure to comply with these warnings violates the safety standards of the 

installation and intended use of the instrument.  Instrutech, Inc. disclaims all liability for the customer’s failure to 
comply with these requirements. 
 
Although every attempt has been made to consider most possible installations, Instrutech cannot anticipate every 
contingency that arises from various installations, operation, or maintenance of the module.  If you have any 
questions about the safe installation and use of this product, please contact Instrutech at the address shown on 
page 1 of this manual.    
 
Service and operation: 
 
Do not modify this product or substitute any parts without authorization of a qualified Instrutech technician.  
Return the product to an Instrutech qualified service and repair center to ensure that all safety features are 
maintained.  Do not use this product if unauthorized modifications have been made.  
 
After servicing this product, ensure that all safety checks are made by a qualified service person. 
Replacement Parts:  When replacement parts are required, ensure that the parts are specified by Instrutech Inc.  
Unauthorized substitutions or non-qualified parts may result in fire, electric shock, or other hazards. 
 
To reduce the risk of fire or electric shock, do not expose this product to rain or moisture.   This product is not 
waterproof and careful attention must be paid to not spill any type of liquid onto this product. 
 
Due to the possibility of corrosion under certain environmental conditions, it is possible that the product’s safety 
could be compromised over time.  It is important that the product be periodically inspected for sound electrical 
connections and grounding.  Do not use if the grounding or electrical insulation has been compromised. 
 
Electrical conditions:

 

 
Danger:  When high voltage is present in any vacuum system, a life threatening electrical shock hazard may exist 
unless all exposed conductors are maintained at earth ground.  This applies to all products that come in contact 
with the gas. 
 
Danger:  An electrical discharge through a gas may couple dangerous high voltage directly to any ungrounded 
conductor.  A person may be seriously injured or killed by coming in contact with an exposed ungrounded 
conductor at a high voltage potential.  This applies to all products that may come in contact with the gas. 
 
Proper Grounding:   
 
Verify that the vacuum port on which the module is mounted is electrically grounded.  This is essential for safety 
as well as proper operation.  The gauge and/or case of the module must be connected to earth ground.  Use a 
ground lug on the flange if necessary. 
 
Overpressure: 
 
Warning:  Install suitable protective devices that will limit the level of the pressure to less than what the vacuum 
system can withstand.  The gauge should not be used above 1000 Torr absolute pressure.
