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. The
products listed below comply with the requirements of the European Pressure Equipment
Directive 97/23/EC. The products fall within the following Pressure Equipment Directive
categories:
1. Safety Information
* SEP= not subjected to CE marking as per paragraph 3.3 of Directive 97/23/EC.
i) The products have been specifically designed for use on compressed air or condensate
which are in Group 2 of the above mentioned Pressure Equipment Directive. The products’
use on other gas within Group 2 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.
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?
