In cold weather, when the Pump is not in use, protect the interior of the Pump from freezing by draining the water and pumping a permanent type automo- bile anti-freeze containing a rust inhibitor through the system. A 50% mixture with water is recommended. Be sure to flush the system with a neutralizing liquid prior to re-use of the Pump. Note: Always properly dispose of all used anti-freeze.
