invite accidents.
2.
3.
Do not operate power tools in explosive atmospheres, such as in the
presence of flammable liquids, gases, or dust. Power tools create sparks
which may ignite the dust or fumes.
Keep bystanders, children, and visitors away while operating a power tool.
Distractions can cause you to lose control.
ELECTRICAL SAFETY
4.
5.
Grounded tools must be plugged into a GFCI (Ground Fault Circuit
Interrupter) outlet, properly installed, and grounded in accordance with all
codes and ordinances. Never remove the grounding prong or modify the
plug in any way. Do not use any adapter plugs. Check with a qualified
electrician if you are in doubt as to whether the outlet is properly grounded.
If the tools should electrically malfunction or break down, grounding provides a
low resistance path to carry electricity away from the user.
Double insulated tools are equipped with a polarized plug (one blade is
wider than the other). This plug will fit in a polarized outlet only one way. If
the plug does not fit fully in the outlet, reverse the plug. If it still does not
fit, contact a qualified electrician to install a polarized outlet. Do not
change the plug in any way. Double insulation
eliminates the need for the
three wire grounded power cord and grounded power supply system.
6.
7.
Avoid body contact with grounded surfaces such as pipes, radiators,
ranges, and refrigerators. There is an increased risk of electric shock if your
body is grounded.
Do not abuse the Power Cord. Never use the Power Cord to carry the tools
or pull the Plug from an outlet. Keep the Power Cord away from heat, oil,
sharp edges, or moving parts. Replace damaged Power Cords immedi-
ately. Damaged Power Cords increase the risk of electric shock.
PERSONAL SAFETY
8.

ating this product. Do not use the Fountain while tired or under the influ-
ence of drugs, alcohol, or medication. A moment of inattention while operat-
ing this product may result in serious personal injury.

GROUNDED TOOLS: TOOLS WITH THREE PRONG PLUGS
1.
Tools marked with “Grounding Required” have a three wire cord and three prong
grounding plug. The plug must be connected to a properly grounded outlet. If
the tool should electrically malfunction or break down, grounding provides a low
resistance path to carry electricity away from the user, reducing the risk of elec-
tric shock. (See Figure B.)
2.
3.
The grounding prong in the plug is connected through the green wire inside the
cord to the grounding system in the tool. The green wire in the cord must be the
only wire connected to the tool’s grounding system and must never be attached
to an electrically “live” terminal. (See Figure B.)
Your tool must be plugged into an appropriate outlet, properly installed and
grounded in accordance with all codes and ordinances. The plug and outlet
should look like those in the following illustration. (See Figure B.)

When unpacking, check to make sure all the parts shown on the Parts List on page 12
are included. If any parts are missing or broken, please call Harbor Freight Tools at the
number shown on the cover of this manual as soon as possible.
ASSEMBLY AND OPERATING INSTRUCTIONS
NOTE:
For additional information regarding the parts listed in the
following pages, refer to the Assembly Diagram on page 13.
1.
2.
3.
WARNING! Always make sure to turn off the electricity powering the
Pump’s electrical outlet and that the Pump is unplugged from its outlet prior to
assembling the unit, unclogging the unit, or making any adjustments to the unit.
If necessary, have a certified electrician install (within 14 feet of where the Pump
will be located) a 120 volt, GFCI electrical outlet that is dedicated only to the
Pump. Any outlet should be well above the water line.
The size of the discharge outlet on the Union (37) is 1-1/2” diameter. Only a
1-1/2” diameter Discharge Pipe (not included) must be used. Do not attempt to
reduce the discharge size below 1-1/2” as this will affect Pump flow and perfor-
mance. (See Figure E, next page.)

4.
Connect the Union (37) to the Coupler (34). Make sure to hand tighten only.
Over-tightening may cause the Union to crack. Then, connect a 1-1/2” diam-
eter Discharge Pipe to the Union. NOTE: Make sure the Discharge Pipe is
secured to a solid surface, with appropriate hardware (not included), to ensure
the stability of the Pump. (See Figure E.)
5.
6.
Install an additional union (not included) or other means of separating the Dis-
charge Pipe just above the floor to facilitate removal of the Pump if necessary.
(See Figure E.)
A check valve (not included) is recommended just above, or in place of, the
Union to prevent the backflow of water after each pump cycle. If a Check Valve
is used, a 1/8” diameter air bleed hole should be drilled through the Discharge
Pipe just above the lower Union (37) to prevent Pump “airlock”. A small spray of
water out of this hole is normal while the Pump is running. (See Figure E.)

Carefully set the Pump in place. Do not lower or raise the Pump by its Power
Cord (1) or Discharge Pipe. (See Figure E.)
The Float Switch (2) automatically switches on and off at a water depth of ap-
proximately 4 inches. The ON/OFF height can be manually adjusted by adjusting
the Float Switch Lock. CAUTION: Do not run the Pump dry. Doing so will
increase wear to the unit and possibly cause seal damage. (See Figure E.)
9.
NOTE: This Pump has a built-in thermal protector for the Motor which automati-
cally shuts it off to avoid overheating. After the Motor cools, it will cycle back on.
Wait for the cycle to continue. Do not try to turn on the Pump manually after it
has automatically shut off.
10.
Connect additional Discharge Pipe as needed to direct the water discharge to the
desired location. The discharge should be kept as short as possible with a mini-
mum number of turns. IMPORTANT: Do not exceed the maximum lift of the
Pump:
1 HP Model 93819 = 33 Feet.
1.2 HP Model 93820 = 36 Feet.
11.
12.
Connect the Power Cord & Plug (1) to its 120 volt, GFCI electrical outlet, while
making sure to form a “drip loop” in the Power Cord. (See Figure A.)
When the water level exceeds approximately 4 inches the Pump will automatically
turn on and run continuously until the water level falls below 4 inches at which
time the Pump will automatically turn off.
13.
WARNING! When shutting off power to the Pump, always shut off the
electrical power to the GFCI outlet first. Then, disconnect the Pump’s Power
Cord & Plug (1) from the GFCI outlet.
INSPECTION, MAINTENANCE, AND CLEANING
