repaired. Remember to share your observations. If the pulse transmitter is not working, notify the
supplier. If after the consultation with the supplier the fault cannot be removed, the water meter should
be left at a service.
11. Safety requirements and environmental aspects
11.1. The water meter is a measurement device which is safe to use if installation and operation
requirements adequate for the intended use are observed.
11.2. During installation, handling and operation there may be threats relating to the water meter itself:
a) mechanical threats:
if carried improperly, it may fall.
water leaks and flooding due to installation of the product which does not agree with
installation requirements or excessive water pressure;
b) thermal threats:
scalding due to contact with the used water meter or a hot water leak.
11.3. To counteract the mechanical threats, the devices have handy grips which enable them to be
conveniently grabbed. In order to counteract the thermal threats, special shields may be used
11.4. In order to install and use the device, choose a well lit, easily accessible place with a hardened
floor surface which prevents fall.
11.5 Water meter components do not contain substances harmful for health and the environment.
All cold water meters are hygienically approved for potable water contact.
11.6 Counter seals and other design solutions protect the water meter from negative influence of steam
condensation on correct reading of indication or transmitter operation.
11.7 Classification of environmental requirements
Classification of mechanical environmental requirements - class M1 acc. to Ordinance of
the Minister of Economy as of 18.12.2006.
Classification of climatic and mechanical environmental requirements - class B - acc. to
PN-EN-14154-3:2005+A1
Classification of environmental electromagnetic requirements - class E1 acc. to Ordinance
of the Minister of Economy as of 18.12.2006.
