General notes 4/26
1 General notes
Note: In the following text, the term meter refers to heat meter and
cooling meter, unless they are otherwise differentiated.
The meter is used as a meter for heating or cooling consumption measurement in systems with water.
The meter consists of a volume measurement unit, two fixed temperature sensors and an electronic unit that calculates the energy consumption from the
volume and temperature difference.

2 Safety information
The meter may only be used in building service engineering
systems and only for the applications described.
The local regulations (installation etc.) must be adhered to.
Adhere to the operating conditions according to the dial plate
during use. Non-adherence can cause hazards and the guarantee will expire.
The meter is only suitable for circulating water in heating systems.
The meter is not suitable for drinking water.
Be aware of sharp edges on thread and measuring tube.
The meter is suitable for circulating water in heating systems.
Adhere to the AGFW requirements regarding circulating water
(FW510).
Do not lift the meter by the electronic unit or by the adapter
plate.
Only personnel, trained in the installation and operation of meters in heating and cooling systems, may install and remove the
meter.
Only install or remove the meter when the pipes are pressureless.
After installing the meter, check the leak-tightness of the system.
Guarantee and calibration validity will lapse if the calibration
relevant security seal is broken.
Only clean the meter from outside with a soft, lightly wetted
cloth. Do not use any spirit or cleaning solvent.
As far as disposal is concerned, the meter is a waste electronic
appliance in the sense of European Directive 2012/19/EU
(WEEE) and it must not be disposed of as domestic waste. The
relevant national, legal regulations must be observed as the
appliance must be disposed of via the channels provided for this
purpose. The local and currently valid legislation must be observed.
The meter contains lithium batteries. Do not dispose of the
meter and the batteries with domestic waste. Observe the local
stipulations and laws on disposal.
Safety information 6/26
You can return the lithium batteries to the manufacturer for
appropriate disposal following use. When shipping please observe legal regulations, in particular, those governing the labelling and packaging of hazardous goods.
Do not open the batteries. Do not bring batteries into contact
with water or expose to temperatures above 80 °C.
The meter does not have any lightning protection. Ensure lightning protection by the house installation.
