On the right, you see the Permeate side of the Permeatepump. You need to get the line coming from your membrane permeate out port directly  connected to the permeate in port of your Permeatepump. From the permeate out port you go to your tank. Make sure, that your hydraulic shutoff valve senses the pressure of your tank, not the pressure before your permeatepump.

There is always a way of finding the outlet ports by touching the area going from the center close to the ports. There is a small pin sticking out that indicates the outlets. This allows you to find out if the pump is installed right even if you can´t directly see it.
