THANKS
We at Kasco Marine, Inc. would like to both thank and
congratulate you on your purchase of the Submersible
Light Kit. The Submersible Light Kit will illuminate

for choosing Kasco for your fountain and aeration
needs and want you to be completely satisfi ed with
your purchase.
Important Safety
Please read and follow these extremely important
safety and handling instructions for your Kasco equipment. Following these instructions will help ensure
your safety and the quality performance of your equipment.
Under NO circumstances should anyone enter •
the water with the electrical equipment plugged
in and/or in operation. All Kasco equipment is
designed and built to UL and CSA standards for
safety in water and all fountain models include
control panels with GFCI protection. However, it
is NEVER recommended to enter the water with
the equipment in operation.
Kasco’s Submersible Light Kits are intended for •
use with a Listed control panel having a GFCI
protected receptacle or fi eld wiring terminals and
disconnect switch, or a timer with a disconnect for
use with a GFCI receptacle. They are intended
to be mounted on a fl oating fountain or aerator
for use in a natural or man-made body of water to
comply with NEC Article 682.
Kasco’s Submersible Light Kits have not been •
evaluated for use in swimming pools, spas or stationary fountains.
All serviceable parts of the light kit are low volt-•
age (12Vac). The power connection for the light
kit is 120Vac and MUST be plugged into a GFCI
receptacle or GFCI protected fi eld terminal con-
nections.
Caution should be used when dealing with any •
electrical and/or moving equipment.
NEVER run the unit out of water. It could create a •
dangerous situation for the operator.
Extreme caution should be used around water, es-•
pecially cold water, as in Spring, Fall, and Winter,
which poses a hazard itself.
NEVER lift or drag the fountain or light kit by the •
power cords. If you need to pull the unit to the
side of the pond, use the anchoring ropes.
Do not use waders in ponds/lakes that are deep, •
with drop-offs, drastic slopes, or soft bottom material.
Do not use a canoe or boat that tips easily during •
installation
The light kit is supplied with an internal ground-•
ing conductor and a grounding-type attachment
plug. To reduce the risk of electrical shock, be
certain that the light kit is connected to the GFCI
protected lighting circuit of your control panel.
For more information regarding your control
panel instructions, refer to your fountain owners
manual or download control panel wiring diagrams
from http://kascomarine.com/instructions.html. A
control panel must be installed a minimum of 5
feet (3m in Canada) from the body of water 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.
