1.0 Introduction 

 
1.1 General 

This installation guide is intended for trained personnel and does not contain any basic working steps. 

 
Important! 

The seal on the energy meter must not be damaged! A damaged seal will result in immediate invalidation of the 
factory warranty and verification. The cables supplied with the meter must not be shortened or changed in any other 
way. 

 
Notes! 

The regulations on the use of energy meters must be observed! 
The meter installation is only to be performed by an installation and/or electrical contractor using personnel trained in 
the installation and use of electrical equipment and familiar with the Low Voltage Directive. 
 
Medium: Water without additives. 
The specified medium temperature is 5...130 °C (150 °C). 

The temperature range depends on variant and nominal size. 

The encapsulated variant is to be used if condensation is expected. 

The specified operating/ambient conditions are 5 … 55 °C; IP54; 93 % rel. humidity. 

 
Further details about the variants can be obtained from the comprehensive Installation and User Guide. Compliance 
with this guide is essential. 

 
1.2 Installation of energy meter 

The energy meter should be installed, as indicated in loop 3 in the display, either in the hot or cold line of the system 
depending on the design and application (heat, air conditioning or cooling meter). 
 
The meter may only be installed in dry and frost-free areas in buildings. 
 
The flow sensor must be installed so that the direction of flow corresponds to the direction of the arrow on the 
sensor. 
 
Ensure that the flow sensor is always filled with liquid during installation. 
 
Calming sections before and after the flow sensor is not necessary. 
 
The meter can be installed in both horizontal and vertical pipe sections, provided air bubbles cannot collect in the 
meter. We recommend installing the flow sensor in a tilted position.
