Essential Instructions

 

Read this page before proceeding

 

Rosemount designs, manufactures, and tests its products to meet many national and international 

standards. Because these instruments are sophisticated technical products, you must properly install, use, 

and maintain them to ensure they continue to operate within their normal specifications. The following 

instructions must be adhered to and integrated into your safety program when installing, using, and 

maintaining Rosemount products. Failure to follow the proper/ instructions may cause any one of the 

following situations to occur: Loss of life; personal injury; property damage; damage to this instrument; and 

warranty invalidation.

 

 

Read all instructions prior to installing, operating, and servicing the product. If this Instruction Manual is 

not the correct manual, telephone 1-800-654-7768 and the requested manual will be provided. Save this 

Instruction Manual for future reference.

 

 

If you do not understand any of the instructions, contact your Rosemount representative for clarification.

 

 

Follow all warnings, cautions, and instructions marked on and supplied with the product.

 

 

Inform and educate your personnel in the proper installation, operation, and maintenance of the product.

 

 

Install your equipment as specified in the Installation Instructions of the appropriate Instruction Manual 

and per applicable local and national codes, for example, ANSI B16.5. Connect all products to the proper 

electrical and pressure sources.

 

 

To ensure proper performance, qualified personnel should install, operate, and maintain the product.

 

 

When replacement parts are required, ensure that qualified people use replacement parts specified by 

Rosemount Analytical. Replacement of original components with those constructed from alternative 

materials will void any CSA, FM, and BASEEFA/CENELEC agency approvals that were applicable to the original 

device. Furthermore, replacement of original components with those constructed from alternative materials 

might change the pressure, temperature, and/or performance specifications from those of the original 

configuration. Ensure replacement parts are compatible with process requirements. Unauthorized parts and 

procedures can affect the product’s performance, place the safe operation of your process at risk, and may 

result in fire, electrical hazards, or improper operation.

 

 

Ensure that all equipment doors are closed and protective covers are in place, except when maintenance is 

being performed by qualified persons, to prevent electrical shock and personal injury.

 

 

DANGER

 

HAZARDOUS AREA INSTALLATION

 

Installations near flammable liquids or in hazardous area locations must be carefully evaluated by qualified 

on site safety personnel. This sensor is not Intrinsically Safe or Explosion Proof.

 

To secure and maintain an intrinsically safe installation, the certified safety barrier, transmitter, and sensor 

combination must be used. The installation system must comply with the governing approval agency (FM, 

CSA, BASEEFA/CENELEC, or ATEX) hazardous area classification requirements. Consult your analyzer/ 

transmitter instruction manual for details.

 

Replacement of original components with those constructed from alternative materials will void any CSA,

 

FM, and BASEEFA/CENELEC agency approvals that were applicable to the original device.

 

Proper installation, operation and servicing of this sensor in a Hazardous Area Installation is entirely the

 

responsibility of the user.

 

 

  

CAUTION: SENSOR/PROCESS APPLICATION COMPATIBILITY 

 

The wetted sensor materials may not be compatible with process com position and operating conditions. 

Replacement of original components with those constructed from alternative materials might change the 

pressure, temperature, and/or performance specifications from those of the original sensor configuration. 

Application compatibility is entirely the responsibility of the user.
