2.To clean the Impeller Cover and Impeller: A clogged or dirty Impeller Cover or Impeller (28) will greatly reduce performance of the Pump. To clean the Impel- ler Cover (31), spray the Cover with clean water. To clean the Impeller, remove the nine Screws (32) at the bottom of the Base (25). Then, remove the Base to expose the Impeller Cover and Impeller. Use a stream of clean water to clean the Impeller and Impeller area inside the Pump. Then, replace the Base. (See Assy.

Diagram.)

3.When finished, store the Pump in a clean, dry and safe location out of reach of children. 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.

CAUTION! All maintenance, service, or repairs not mentioned in this manual must only be performed by a qualified service technician.
