GENERAL SAFETY INFORMATION
Electrically powered sump pumps normally give
many years of trouble-free service when correctly
installed, maintained, and used. However, unusual
circumstances (interruption of power to the pump,
dirt/debris in the sump, flooding that exceeds the
pump’s capacity, electrical or mechanical failure in
the pump, etc.) may prevent your pump from func-
tioning normally. To prevent possible water damage
due to flooding, consult your retailer about a sec-
ondary AC sump pump, a DC backup sump pump,
and/or a high water alarm. See the “Troubleshooting
Chart” in this manual for information about common
sump pump problems and remedies. For more infor-
mation, see your retailer or call customer service at
1-800-468-7867.
1. Know the pump application, limitations, and
potential hazards.
2. Do not use in water with fish present. If any oil
leaks out of the motor it can kill fish.
3. Disconnect power before servicing.
4. Release all pressure within system before servic-
ing any component.
5. Drain all water from system before servicing.
6. Secure discharge line before starting pump. An
unsecured discharge line will whip, possibly
causing personal injury and/or property damage.
7. Check hoses for weak or worn condition before
each use, making certain that all connections are
secure.
8. Periodically inspect sump, pump and system
components. Keep free of debris and foreign
objects. Perform routine maintenance as
required.
9. Provide means of pressure relief for pumps whose
discharge line can be shut-off or obstructed.
10. Personal Safety:
a. Wear safety glasses at all times when working
with pumps.
b. Keep work area clean, uncluttered and prop-
erly lighted – replace all unused tools and
equipment.
c. Keep visitors at a safe distance from work
area.
d. Make workshop child-proof – with padlocks,
master switches, and by removing starter
keys.
11. When wiring an electrically driven pump, follow
all electrical and safety codes that apply.
12. This equipment is only for use on 115 volt
(single phase) and is equipped with an
approved 3-conductor cord and 3-prong,
grounding-type plug.
