Mechanical Installation

1. Make sure there is sufficient space for the connecting cable and tubing connections.
Ä This will prevent kinks from forming in the connecting cables and the tubing.
2. Place the valve as close to the consumer as possible.
Ä This leads to improved control precision and shorter response times.
