ATTENTION:
Pumps which are not in use during freezing periods should be drained to
avoid damage. Drain the pump by loosening the vent screw in the pump
head and removing the drain plug from the base.
DANGER:
Pay attention to the direction of the vent hole and make sure that the
water coming out of the pump does not cause injuries to people or any
damage to the motor or other components. In the case of hot-water
installations, pay special attention to the risk of injuries from scalding hot
water.
Do not tighten the vent screw and place the drain plug until the pumps is
