Execution
Perform the installation as follows:
•
Preferably install the device in the return side of the plant system. In this manner, you ensure that the device is operated within the
permissible pressure and temperature ranges.
•
In the case of a plant system with return flow admixture or hydraulic switching points, install the device upstream of the mixing
point. In this way, it is ensured that the degassing of water from the main volume flow takes place within the permissible
temperature range.
CAUTION – damage due to improper connection! Bear in mind that the device may be subject to additional stresses through the
connection of piping or hose connections to the plant system. Ensure that all connections to the plant system are free from stresses. If
necessary, provide support structures for the pipes.
CAUTION – Property damage caused by leaks! Leaks in the connection lines to the device can cause material damage to the plant system.
Use only connection lines with appropriate resistance against the plant system temperature.
The device is pre-wired and must be adapted for the local system conditions. Complete the water-side connection to the system and the
electric connection as shown in the terminal diagram, see chapter 6.5 "Electrical connection" on page 30 .
Note!
During installation, pay attention to the operability of the valves and the inlet options for the connecting lines.
