5. Installation
5.1.
General installation information
During the entire process of installation, the device must not be connected to the
electrical mains.
The pump and the entire connection system have to be protected from frost.
All connection lines have to be perfectly tight since leaking lines may affect the performance of the
pump and cause considerable damage. If required, please use a suitable sealant to make the
installation airtight.
Avoid excessive force when tightening the screwed connections, which can lead to damage. When
laying the connection pipes, you should make sure that the pump is not exposed to any form of
weight, vibration or tension. Moreover, the connection lines must not contain any kinks or an adverse
slope.
Please observe the illustrations, too, which are contained as an attachment at the end of the present
operating instructions. The numeric and other details included in brackets below refer to these
illustrations.
