9. FROST PROTECTION

Pumps which are not being used during periods of frost should be drained to avoid damage.
Drain the pump by loosening the vent screw in the pump head and by removing the drain plug
from the base. Care must be taken to ensure that the escaping water does not cause injury to
persons of damage to the motor or other components. In hot-water installations, special attention
should be paid to the risk of injury caused by scalding hot water. Do not tighten the vent screw and
replace the drain plug until the pump is to be used again.
