-
This product fulfils the requirements of the European Council Directive on Electromagnetic Compatibility
(EMC Directive) 2004/108/EC.
-
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guarantee and the approved application of the instrument are no longer valid!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 is it 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.
-
The instrument must be stored and transported at temperatures above-freezing.
-
Instruments with activated radio function are not allowed on air freight.
-
The correct installation point in the system must be chosen: forward or return flow, as stated on the type
identification label.
-
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 meter should only be removed from the packaging directly before
installation.
-
If more than one meter is installed in one unit, care must be taken to ensure that all the meters have the
same installation conditions.
