➔ Connect the calble.

(see Figs. under Connection Configuration)

➔➔

➔ Put on the lid of the control unit.

➔➔

➔ Plug the controller (flow, pressure or temperature) onto the

valve.

➔➔

➔ Screw the controller tight.

When screwing the controller to the proportional valve,

ensure that the seal is properly seated!
