Debris Management
Some ponds or lakes present challenges for the pump because of debris. The debris can enter the propeller area and quickly
reduce performance of the fountain. For situations such as these, a debris barrier can be constructed to minimize clogging of
the propeller, but is not a guarantee.
Material that should be considered for constructing after-market debris barriers are mesh type configurations, either using
plastic or non-corrosive metal material. The barrier should be installed around the perimeter of the float's inner diameter
(Figure 11). For convenience (8) ¼-20 brass inserts have been molded into the perimeter of the float's inner diameter. Also
note it is important to keep the barrier away from the flow of water around the motor. Placing barrier material across
the flow of water along the motor will significantly affect the motor's ability to cool, especially once the barrier material
becomes blocked with debris, thereby shortening the life of the unit.
Please note once a debris barrier is installed, it will have to be cleaned frequently to remove debris and maintain good water
flow across the motor. If this is not done, performance will be reduced and/or damage could occur. Also remember not to
regard the barrier as a safety device, and warn other workers of the same.

Storage
Place unit in an upright position, and protect from exposure to temperatures below -20 °F (-29 °C) and above 120 °F (49 °C).
The most desired method of storing the unit would be to leave it in the pond or lake, as long as the unit is not allowed to
freeze. The original carton can be used to transport and protect the unit while in storage.
