i)  The product has been specifically designed for use on steam, air or condensate 

which is 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.
