Read the warning mark before start-up.
Note: Do not start the pump until it has been fi lled with liquid and vented. If the pump runs dry, the
pump bearing and the shaft seal may be damaged.
Pay attention to the direction of the vent hole and take care to ensure that the escaping water
does not cause injury to persons or damage to the motor or other components. In hot-water insta-
llation, special attention should be paid to the risk of injury caused by scalding hot water.

For these pumps, it is advisable to open the by pass valve during start-up. The bypass valve con-
nects the suction and discharge sides of the pump, thus making the fi lling procedure easier. When
the operation is stable, the bypass valve can be closed. When pumping liquids containing air, it is
advisable to leave the bypass valve open if the operating pressure is lower than 6 bar.
If the operating pressure constantly exceeds 6 bar, the bypass valve must be closed. Otherwise
the material at the opening will be worn because of the high liquid velocity.
