i)  This product has been specifically designed for use on steam, air or water/

condensate which are in Group 2 of the above mentioned Pressure Equipment 

Directive. The products’ use on other fluids may be possible but, if this is 

contemplated, Spirax Sarco should be contacted to confirm the suitability of              

the product for the application being considered.

ii)  Check material suitability, pressure and temperature and their maximum and 

minimum values. If the maximum operating limits of the product are lower than 

those of the system in which it is being fitted, or if malfunction of the product 

could result in a dangerous overpressure or overtemperature occurrence, ensure 

a safety device is included in the system to prevent such over-limit situations.

iii)  Determine the correct installation situation and direction of fluid flow. 

iv)  Spirax Sarco products are not intended to withstand external stresses that may 

be induced by any system to which they are fitted. It is the responsibility of the 

installer to consider these stresses and take adequate precautions to minimise 

them.

v)  Remove protection covers from all connections and  protective  film  from  all                  

name-plates, where appropriate, before installation on steam or other high 

temperature applications.

1.2 Access

Ensure safe access and if necessary a safe working platform (suitably guarded)          

before attempting to work on the product. Arrange suitable lifting gear if required.

1.3 Lighting

Ensure adequate lighting, particularly where detailed or intricate work is required.
