Warning
Isolate the mains supply before unplugging the controller since hazardous
voltages will be exposed on the controller base. This product complies with
the requirements of Electromagnetic Compatibility Directive 89 / 336 / EEC and
93 / 68 / EEC by meeting the standards of:
- EN 61326 : 1997 A1 + A2 Emissions Class B equipment Table 4.
- EN 61326 : 1997 A1 + A2 Immunity for Industrial Locations Annex A.
The following conditions should be avoided as they may create interference above
the limits specified in EN 61326 (Immunity) 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 vary according to the surroundings of the
installation and the power of the transmitter.
If this product is not used in the manner specified by this IMI, then the protection
provided may be impaired.
1.1 Intended use
i) Check that the product is suitable for use with the intended fluid.
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.
Safe operation of this product can only be guaranteed if it is properly installed,
commissioned, used and maintained by qualified personnel (see Section 1.11)
in compliance with the operating instructions. General installation and safety
instructions for pipeline and plant construction, as well as the proper use of tools
