Operating Instructions HYGROPHIL® H 4230-12 BA 060207

6.12

Replacing the proportional valve



First dismount the display-/ profibus-board and the electronics board (fol-

low the instructions according to section 6.10 and 6.11).



Disconnect the two blue hoses from the proportional valve



For this press in hose catch at the nipple and pull out the hose at the

same time.



Unscrew the two allen screws and take the valve out.



Insert the new proportional valve and fix it with the two screws.



Connect the two hoses to their nipples.



Reassemble the display-/ profibus board and the electronics board.



Connect the plug of the proportional valve to the electronics board (see

page 84).
