Assembly of the volume measuring section
• The flow direction can be recognised from the arrows on the electronics housing of the
flow measuring section. 
• The meter does not need an inflow or outflow section.
• Preferred installation locations (condition as supplied):
- Heat meter outlet/low temperature
• Optional installation locations (change in configuration required)
- Heat meter inlet/high temperature
• If replacing a meter, be sure to clean the sealing surfaces of the union piece connector.
Use new seals.
• Open the shut-off devices and check their leak-tightness.
• After installation, perform test for function and leaks.
Suitable and unsuitable installation locations 
A, B: OK,
C: not OK
Installation at a high point only if a bleeding option exists.
D: Only OK in closed systems
E: not OK - directly after a restriction or a reducing component
F: not OK - too close on the suction side of a pump
G: not OK - after a bypass loop in two levels
Installation positions
• Horizontal, vertical or at an angle
• Rotated up to 45° upwards to the pipe axle 
• Rotated up to 90° downwards to the pipe axle 
• With low flow volumes, it is recommended that the installation position be tilted by 45°
to the pipe axis.
!
If possible, use the same installation method within one property!
Assembly of the computer unit
The computer unit must be accessible at all times and readable without further aids.
Compact assembly
• Compact assembly is only admissible between 15 °C and 90 °C medium temperature.
• With media temperatures of more than 90 °C, the computer unit must be mounted
separately.
• Assembly directly on the volume measuring section.
Wall assembly, optionally with mounting kit 
Select a dry, easily accessible location.
1
Observe the length of the lines at the computer unit.
2
Mount the computer unit at the wall using the fastening material.
