8. Periodically inspect the pump and system components.
Keep free of debris and foreign objects. Perform routine
maintenance as required.
9. Provide a means of pressure relief for pumps whose dis-
charge line can be shut-off or obstructed.
10. Personal Safety:
a. Wear safety glasses at all times when working with
the pumps.
b. Keep work area clean, uncluttered and properly light-
ed – replace all unused tools and equipment.
c. Keep visitors at a safe distance from the work area.
d. Make the workshop child-proof – with padlocks, mas-
ter switches, and by removing starter keys.
11. When wiring an electrically driven pump, follow all of the
electrical and safety codes that apply.
12. This equipment is only for use on 120 volt (single
phase) and is equipped with an approved 3-conduc-
tor cord and 3-prong, grounding-type plug.
Hazardous voltage. Can shock, burn or
cause death. To reduce the risk of electric shock, pull
the plug before servicing. This pump has not been inves-
tigated for use in swimming pool areas. The pump is
supplied with a grounding conductor and grounding-type
attachment plug. Be sure it is connected only to a prop-
erly grounded grounding-type receptacle.
Where a 2-prong wall receptacle is encountered, it must
be replaced with properly grounded 3-prong receptacle
installed in accordance with the codes and ordinances
that apply.
Do not walk on wet area until all power has been
turned off. If the shut-off box is in the basement, call
the electric company or hydro authority to shutoff the
service to house, or call your local fire department for
instructions. Failure to follow this warning can result in a
fatal electrical shock.
Do not lift the pump by the power cord.
13. All wiring should be performed by a qualified
electrician.
14. Make certain the power source conforms to the require-
ments of your equipment.
15. Protect the electrical cord from sharp objects, hot sur-
faces, oil, and chemicals. Avoid kinking the cord.
Replace or repair damaged or worn cords immediately.
16. Do not touch an operating motor. Modern motors are
designed to operate at high temperatures.
17. Do not handle the pump or pump motor, or change
fuses with wet hands or when standing on a wet or
damp surface, or in water.
INSTALLATION
1. Set the pump on a hard surface in at least 2" of water.
2. Connect the discharge line with the fittings provided.
3. The pump should not be installed on clay, dirt, mud or
sand surfaces. Although the pump will usually pass
small particles suspended in water, clean the area to be
pumped of small stones and gravel which could clog the
pump.
*NOTICE: Grass, mud, sand or pea gravel can clog the
pump and reduce it's performance. Keep the pump inlet
screen clean.
4. To reduce motor noise and vibrations when using rigid
pipe, a short length of rubber hose (e.g. radiator hose)
can be connected into the discharge line near the pump
using suitable clamps.
5. Power Supply: These pumps are designed for 120 V., 60
Hz., operation and requires a minimum 15 amp individ-
ual branch circuit. Pump is supplied with a 3-wire cord
with grounding-type plug.
Hazardous voltage. Can shock, burn or
cause death. Pump should always be electrically
grounded to a suitable electrical ground such as a
grounded water pipe or a properly grounded metallic
raceway, or ground wire system. Do not cut off round
ground pin.
6. If the pump discharge line is exposed to an outside sub-
freezing atmosphere, the line exposed must be installed
so any water remaining in pipe will drain to the outfall by
gravity. Failure to do this can cause water trapped in the
discharge line to freeze which could result in damage to
pump.
7. Check the operation of pump by observing through one
complete cycle.
Risk of flooding. Failure to make this
operational check may lead to improper operation, pre-
mature failure, and flooding.
OPERATION
Hazardous voltage. Can shock, burn or
cause death. Do not handle a pump or pump motor with
wet hands or when standing on wet or damp surface, or in
water.
Before attempting to check why a unit has stopped operat-
ing, disconnect power from the unit.
1. The shaft seal depends on water for lubrication and for
cooling. Do not operate the pump unless it is submerged
in water as the seal may be damaged if allowed to run
dry.
2. The pump will not remove all water. On a flat surface
these pumps will pump down to within 1/8" of the pump-
ing surface.
NOTICE: For continuous operation, the pump must be
submerged to prevent the motor from overheating. A
fully submerged pump is preferred for proper cooling
when a pump runs continuously.
AIRLOCKS
When a pump airlocks, it runs but does not move any water.
An airlock will cause the pump to overheat and fail. Pump
model number US42518M-01 has a built in anti-airlock hole.
See the exploded view on the repair parts page for the loca-
tion of the hole. Leakage from the anti-airlock hole is normal.
If you suspect an airlock, unplug the pump, clean out the
anti-airlock hole with a paper clip or a piece of wire, and
restart the pump.
