GUIDELINE ON VALVE INSTALLATION

In the case of suction problems during installation, place the valves on a firm surface and tap the
PTFE ball seat disk lightly with a brass rod and a hammer weighing about 300 g. Let the valves
operate in the wet state.

NOTE

• If suction problems with the pump or leakage at the overcurrent valve are encountered,

first clean the ball and the ball seat disc.

• For media containing particles larger than 0.3 mm it is absolutely essential to install a

filter in the suction line.
