OPERATION AND MAINTENANCE
WARNING: Always unplug or disconnect all appliances in the pond from the electrical supply before installing,
repairing, maintaining or handling the equipment in the water.
To avoid shortening the life of the pump, follow these simple maintenance procedures:
-Once a week, verify that the pump performance is satisfactory. If you detect a drop in pump performance (such
as a decrease in water ow from the pump or to the waterfall) rst clean the pump’s pre-lter cage and tubing. If
the water ow is still not fully restored to its original performance, clean the impeller and internal pump body.
-The pump impeller includes a high quality ceramic shaft that provides long-lasting, reliable performance when
properly maintained. However, extreme care should be taken when handling the shaft during maintenance.
Avoid dropping or pressing too hard on it to avoid breakage or hairline fractures, which may cause the shaft to
snap while in operation.
-This pump is suitable for use in water temperatures from 32 degrees Fahrenheit (0 degrees Celsius) to 95 degrees
Fahrenheit (35 degrees Celsius).
-To keep the pump in long lasting working conditions, always replace any worn parts.
Pump Pre-Filter Cage
Do not remove the pump’s pre-lter cage while operating the pump. Failure to operate the pump
without the pre-lter cage or operating the pump with a broken cage will allow large debris to enter the pump
causing damage to the pump, thus voiding the warranty.

Pump Pre-Filter Cleaning
We recommend inspecting your pump on a regular basis to ensure it is functioning properly. If you notice
the water ow rate diminish, it may be due to the pump’s pre-lter cage being blocked with debris. In many cases,
the clogged lter cage can be cleaned by reaching into the pond and pulling the pump out of the water to remove
the debris from the lter cage.
Important Note: Always disconnect the power before performing maintenance on the pump. Pull o any debris
stuck to the pump pre-lter cage and/or use a garden hose to spray o any debris stuck to the lter cage.
