Connecting the pressure line
• The pressure outlet of the ZP SPEEDCONTROL has to be
preferably provided with a flat-sealing connecting coupling.
That way, the pump can be easily mounted and dismounted
later (e.g. for maintenance purposes).
• The inside diameter of the pressure line must be at least ¾“
• Seal the construction-side pressure line and connect it with the
connecting coupling of the pressure socket
