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 Spirax Sarco
EasiHeatTM DHW potable and process water heating compact heat transfer unit complies with the
requirements of the
Pressure Equipment Directive (PED) - F
or any product specific PED
catagorisation that is required for this unit or products used in the make-up of the unit p
lease
contact
Spirax Sarco directly.
i) The product has been specifically designed for use on steam or water/condensate
which are in Group 2 of the above mentioned Pressure Equipment Directive (PED).
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.
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.
