Before start-up:
The pump can be connected to any shock-proof plug
which has been installed according to regulations.
The plug must have a supply voltage of 120 V~ at 60 Hz.
7. The pump must be protected from frost.
8. The pump must be protected from running dry.
9. Access by children should also be
prevented with appropriate measures.
CAUTION:
This pump has been evaluated for use with clear water
only. Do not use in or around swimming pools.
WARNING:
IMPORTANT! For your own safety – before
starting to run the pump, please have the
following items checked by an expert:
1. To reduce the risk of electric shock, use
only on portable self-contained fountains
no larger than 5 feet in any dimension.
2. Risk of electric shock – This pump is supplied with a
grounding conductor and grounding-type attachment
plug. To reduce the risk of electric shock, connect only
to a properly grounded, grounding-type receptacle.
3. Risk of electric shock – This pump has not been
investigated for use in swimming pool areas.
4. The electrical connections must be
protected from moisture.
5. If there is danger of ooding, the electrical
connections must be taken to higher ground.
6. Circulation of caustic uids, as well as the circulation
of abrasive materials, must be avoided at all costs.
10. To avoid the possibility of the pump plug or receptacle
getting wet, position pump to one side of a wall
mounted receptacle to prevent water from dripping
onto the receptacle or plug. The user should arrange
a “drip loop” in the cord connecting the pump to a
receptacle. The “drip loop” is that part of the cord
below the level of the receptacle, or the connector if an
extension cord is used, to prevent water traveling along
the cord and coming in contact with the receptacle.

will expose you to lead, a chemical known to the State
of California to cause cancer, and birth defects or
other reproductive harm. Wash hands after handling.
