Important Safety Instructions
Please read and follow these extremely important 
safety and handling instructions for your Kasco equip-
ment. Following these instructions will help ensure 
your safety and the quality performance of your equip-
ment.
•  Under NO circumstances should anyone enter the 
water with the electrical equipment plugged in 
and/or in operation. All Kasco equipment is ETL 
approved to UL and CSA standards for safety in 
water. However, it is NEVER recommended to 
enter the water with the equipment in operation.
•  Caution should be used when dealing with any 
electrical and/or moving equipment.
•  NEVER run the unit out of water. It will damage 
the seals and create a dangerous situation for the 
operator.
•  Extreme caution should be used around water, 
especially cold water, such as in Spring, Fall, and 
Winter, which poses a hazard in and of itself.
•  NEVER lift or drag the pond aerator or water 
circulator by the power cord. If you need to pull 
the unit to the side of the pond, use the anchoring 
ropes.
•  Do not use waders in deep ponds/lakes or ponds/
lakes with drop-offs, drastic slopes, or soft bottom 
material.
•  Do not use boats that tip easily for aerator installa-
tion, such as a canoe, and follow all boating safety 
rules and regulations, including wearing a PFD 
(Personal Flotation Device).
•  Single phase Pond Aerators or Water Circulators 
are supplied with an internal grounding conductor 
and a grounding-type attachment plug. To reduce 
the risk of electrical shock, be certain that the pond 
aerator or water circulator is plugged into a GFI 
protected circuit.
•  3 phase aerators (2.3, 3.3, 5.3) require a startup 
test after wiring to ensure proper rotation of the 
propeller. If the propeller is rotating in the op-
posite direction, the unit will not perform properly 
and internal damage to the unit may occur. (See 3 
phase startup procedure)
•  Control panels must be installed a minimum of 
5ft(3m in Canada) from the inside wall of the 
pond, unless separated from the body of water by 
a fence wall, or other permanent barrier that will 
make the unit inaccessible to persons in the water.  
•  Control panels must be installed by a qualied 
electrician.
•  Ground Fault Circuit Interrupters (GFCI) should 
be tested upon each installation and every month 
thereafter to ensure proper operation.
