i) The products have been specifically designed for use on steam, water and other
non-hazardous fluids 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 before installation.
