Damage due to improper installation
Additional device stresses may arise due to the connection of pipes or system equipment.
• Ensure that pipes are connected from the device to the system without stresses being induced.
• If necessary, provide support structures for the pipes or equipment.
Device damage resulting from dry running of the pump
If the pump is incorrectly connected, there is a risk of dry-running.
• Ensure that the connections for the overflow collector and the pump are not interchanged.
• Ensure correct connection of the pump to the primary tank.
Comply with the following notes regarding the
installation of
the primary tank and the secondary tanks:
All flange openings at the tanks are viewing and
maintenance openings. Install the primary tank and the
secondary tanks, if provided, with sufficient spaces at the
sides and the top.
Install the tanks on a level surface.
Ensure rectangular and free-standing position of the tanks.
If you use secondary tanks in addition to the primary tank,
ensure that all tanks are of the same type and dimensions.
Do not attach the tanks to the flooring to ensure the
functioning of the "LIS" level sensor.
Install the control unit on the same level as the tanks.
