Page 3: Planning Considerations And Precautions
If installing S-link products DO NOT connect any other control equipment to the S-link controlled products except Sleipner original S-link products or via a Sleipner supplied interface product made for interfacing with other controls. Any attempt to directly control or at all connect into the S-link control system without the designated and approved interface will render all warranties and responsibilities for the complete line of Sleipner products connected void and null. -

Page 7: Tunnel Length
Do not allow the variable length of the tunnel walls to vary in length excessively. EG. the top tunnel wall is x 4 longer than the bottom wall. Water flow must have space to "straighten" itself for best Cavitation performance. -
