B850-W and B850-P Boiler House Energy Monitor
The product may be exposed to interference above the limits of EN 61326 if:
-
The product or its wiring is located near a radio transmitter.
-
Excessive electrical noise occurs on the mains supply. Power line
protectors (ac) should be installed if mains supply noise is likely.
Protectors can combine filtering, suppression, surge and spike arrestors.
-
Cellular telephones and mobile radios may cause interference if used
within approximately 1 metre (39") of the product or its wiring. The actual
separation distance necessary will vary according to the surroundings
of the installation and the power of the transmitter.
2.1 Intended use
i) Check that the product is suitable for use with the application.
ii) Determine the correct installation situation and direction of fluid flow.
iii) 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.
2.2 Access
Ensure safe access and if necessary a safe working platform (suitably
guarded) before attempting to work on the product.
2.3 Lighting
Ensure adequate lighting, particularly where detailed or intricate work is
required.
2.4 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.
2.5 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.
2.6 Tools and consumables
Before starting work ensure that you have suitable tools and
/
or consumables
available.
