3 General Information
- Valid standards for the application of heat meters: EN 1434, parts 1 – 6; the Measuring Instruments
Directive 2014/32/EU, Annexes I and MI-004; and the relevant national verification regulations.
- For the selection, installation, commissioning, monitoring and maintenance of the instrument observe the
standard EN 1434 part 6, as well as the verification regulations PTB TR K8 + K9 for Germany (and any
relevant national verification regulations in other countries).
- For combined heat/cooling meters the cooling register has no verification. National regulations for the
consumption measurement of cooling must be observed.
- The technical regulations for electrical installations must be observed.
- This product fulfils the requirements of the European Council Directive on Electromagnetic Compatibility
(EMC Directive) 2014/30/EU.
- The identification plate of the instrument and the seals must not be removed or damaged – otherwise the
guarantee and the approved application of the instrument are no longer valid!
- To achieve measurement stability of the meter it is necessary that the water quality meet the requirements
of the AGFW-recommendation FW-510 and the document VDI (Association of German Engineers) VDI 2035.
- The heat meter left the factory in conformance with all applicable safety regulations. All maintenance and
repair work is to be carried out only by qualified and authorized technical personnel.
- Instruments with activated radio function are not allowed on air freight.
- The correct installation point in the system must be chosen: inlet or outlet flow (see item 3.1 ’Pictograms
installation point’).
- The temperature sensor cables and the cable between the calculator and flow sensor must not be kinked,
rolled up, lengthened or shortened.
- To clean the heat meter (only if necessary) use a slightly moist cloth.
- To protect against damage and dirt the heat meter should only be removed from the packaging directly
before installation.
- If more than one heat meter is installed in one unit, care must be taken to ensure that all the meters have
the same installation conditions.
- All specifications and instructions listed on the data sheet and in the Application Notes must be adhered to.
Further information can be obtained at www.engelmann.de.
- The heat meter has a lithium-metal-battery. Do not open the batteries, do not bring the batteries into
contact with water or expose them to temperatures above 80 °C. Do not charge them or short-circuit them.
