i)  These products have been specifically designed for use on steam, air or condensate/water, 

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

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, where appropriate, before installation on 

steam or other high temperature applications.
