1.1 Intended use
Referring to the Installation and Maintenance Instructions, name-plate and Technical
Information Sheet, check that the product is suitable for the intended use/application.
i) The product has been specifically designed for use on steam or water/condensate. 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
over-pressure or over-temperature 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.
1.4 Hazardous liquids or gases in the pipeline
Consider what is in the pipeline or what may have been in the pipeline at some previous
time. Consider: flammable materials, substances hazardous to health, extremes of
temperature.
1.5 Hazardous environment around the product
Consider: explosion risk areas, lack of oxygen (e.g. tanks, pits), dangerous gases, extremes
of temperature, hot surfaces, fire hazard (e.g. during welding), excessive noise, moving
machinery.
1.6 The system
Consider the effect on the complete system of the work proposed. Will any proposed
action (e.g. closing isolation valves, electrical isolation) put any other part of the system
or any personnel at risk?
Dangers might include isolation of vents or protective devices or the rendering ineffective
of controls or alarms. Ensure isolation valves are turned on and off in a gradual way to
avoid system shocks.
