WARNING

When using electric pumps, basic safety
precautions should always be followed to reduce the risk

of re, electric shock, and personal injury. READ ALL
INSTRUCTIONS BEFORE USING THIS PUMP!

1. This Pump has not been investigated for use in

swimming pool or marine areas.

2. Use only with clear water. Do not use with

ammable liquids such as gasoline, chemicals or

and corrosive liquids.

12. The pump must be protected from running dry.

13. Do not run the pump with the outlet closed or
blocked. The connections may burst due to
excessive pressure.

14. WARNING: Handling the cord on this product will
expose you to lead, a chemical known to the State
of California to cause cancer, and birth defects
or other reproductive harm. Wash hands after
handling. (California Health & Safety Code §

25249.5, et seq.)

3. Risk of electric shock – This pump is supplied
with a grounding conductor and grounding-type
attachment plug. To reduce the risk of electric
shock, connect only to a properly grounded,
grounding-type receptacle.

4. If there is danger of ooding, the electrical
connections must be taken to higher ground.

5. DO NOT IMMERSE IN WATER. This is not a
submersible pump. Use indoors only.

6. Always lock up pumps and keep out of reach of
children.

7. Wear ANSI-approved safety goggles during
installation.

8. DISCONNECT POWER. Unplug when not in use,
before servicing, and when changing accessories.

9. CHECK DAMAGED PARTS. Before using any
pump, check for alignment and binding of moving

parts; any broken parts or mounting xtures;

and any other condition that may affect proper
operation. Any part that is damaged should

be properly repaired or replaced by a qualied

technician.

10. REPLACEMENT PARTS AND ACCESSORIES.
When servicing, use only identical replacement
parts. Use of any other parts will void the warranty.
Only use accessories intended for use with this
pump. Approved accessories are available from
Harbor Freight Tools.

11. The pump must be protected from frost.

Grounding Instructions

6. Do not use an adapter to connect this pump to a
different outlet.

TO PREVENT ELECTRIC

SHOCK AND DEATH FROM
INCORRECT GROUNDING WIRE
CONNECTION
READ AND FOLLOW THESE
INSTRUCTIONS:

Check with a qualied electrician if you are in doubt

as to whether the outlet is properly grounded. Do not
modify the power cord plug provided with the tool. Never
remove the grounding prong from the plug. Do not
use the tool if the power cord or plug is damaged. If
damaged, have it repaired by a service facility before

use. If the plug will not t the outlet, have a proper outlet
installed by a qualied electrician.

Grounding

Pin

Extension Cords

1. Grounded tools require a three wire extension
cord. Double Insulated tools can use either a two
or three wire extension cord.

2. As the distance from the supply outlet increases,
you must use a heavier gauge extension cord.
Using extension cords with inadequately sized wire
causes a serious drop in voltage, resulting in loss
of power and possible tool damage. (See Table A.)

3. The smaller the gauge number of the wire, the
greater the capacity of the cord. For example, a
14 gauge cord can carry a higher current than a 16
gauge cord. (See Table A.)

4. When using more than one extension cord to
make up the total length, make sure each cord
contains at least the minimum wire size required.

(See Table A.)

5. If you are using one extension cord for more than
one tool, add the nameplate amperes and use the
sum to determine the required minimum cord size.

(See Table A.)

125 V~ 3-Prong Plug and Outlet

(for up to 125 V~ and up to 15 A)

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 electric shock. (See

3-Prong Plug and Outlet.)

2. 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 3-Prong Plug

and Outlet.)

3. The 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 preceding illustration.

(See 3-Prong Plug and Outlet.)

4. This pump is intended for use on a circuit that has
an outlet that looks like the one illustrated above in
125 V~ 3-Prong Plug and Outlet. The pump has
a grounding plug that looks like the plug illustrated
above in 125 V~ 3-Prong Plug and Outlet.

6. If you are using an extension cord outdoors, make

sure it is marked with the sufx “W-A” (“W” in

Canada) to indicate it is acceptable for outdoor use.

7. Make sure the extension cord is properly wired
and in good electrical condition. Always replace a
damaged extension cord or have it repaired by a

qualied electrician before using it.

8. Protect the extension cords from sharp objects,
excessive heat, and damp or wet areas.

Pipe Connection

The Pump uses 1" NPT piping (sold separately).

Purchase the necessary length of pipe, including any

needed ttings and bends. Mount the Pump as close to

the source of water as possible and within the range of
the rated Suction Lift. The connections must be airtight.

Unpacking

When unpacking, make sure that the item is intact
and undamaged. If any parts are missing or broken,
please call Harbor Freight Tools at 1-800-444-3353 as
soon as possible.

3. Install a foot valve and lter (sold separately) at the
bottom of the inlet.

4. Attach the outlet connection to the Outlet. A

Y-tting with dual valves (sold separately) is helpful

for priming the pump (see next section).

Operation

TO PREVENT ELECTRIC

SHOCK AND DEATH:

Make sure that the Connection Box Cover
(42) is properly closed and sealed before
priming or operation.

Note: A foot valve on the inlet connection is critical to help

prevent the pump from losing prime.

Note: Check that the water source and piping are clear of

sand, dirt and debris.

Bucket

full of

clean

water

Priming Hose

Outlet Pipe

5. If you operate the Pump and no water comes out,
shut the Pump off IMMEDIATELY. Check the pipes
for air-tightness. Check also that the bottom of the
Inlet pipe is underneath the surface of the water
and a foot valve is properly installed.

6. After the pump is running properly, the priming
hose and bucket can be disconnected.

Storage

1. If you will not be using the Pump for an extended
period of time, drain the Pump Body (22). First
disconnect both the suction and outlet lines, then
tip the pump so that all the water is drained from
the pump cavity.

2. If the Pump sits idle for a period of 5 days or
more, it should be unplugged and rotated with
a screwdriver through the middle hole of the fan
cover through several revolutions to prevent it from
taking a permanent set.

3. If you use the Pump only occasionally, when you
are done pumping, replace the Inlet and Outlet
covers to protect the unit.

Y-tting

(with one valve
for each outlet)

Valve

1.

Connect a bucket full of at least 3 gallons of water

to one side of the Y-tting using a hose, as shown

above. (If available, a continuous water supply,
such as a spigot, may be used instead.) The
bucket must be positioned higher than the pump’s
outlet.

2. Close the valve on the outlet side of the Y-tting,
and open the valve on the priming side of the

Y-tting.

3. Remove the Priming Plug (23) and wait until water
starts coming out of the Priming Plug. Replace the
Priming Plug and tighten securely.

4. To start the pump:

a. Open the valve on outlet side of the Y-tting.

b. Make sure your hands are dry.

c. Plug in the pump.

d. Close the valve on the priming side of the Y-tting.

CAUTION: Do not run the Pump Dry! Turn off the

Pump IMMEDIATELY if water stops coming out
the Outlet.
