When unpacking, make sure 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.
The submersible pump must be installed
in a stationary position with either:
A fixed pipeline ora.
A flexible hose.b.
The Universal Fitting (37) connects from
1-1/2”, 1-1/4” and 1” size hoses using a hose
step nipple (not included). See Figure 1. The
1” and 1-1/4” hoses should also be secured
with hose clamps (not included).
The largest connection (1-1/2”) will yield the
greatest flow. The top of the Universal Fitting
may be removed to fit on various size hoses.
Use a knife to gently cut off any unneeded
Do not install the pump by suspending 1.
it unsupported from its delivery pipe
or power cord. The pump must be
suspended from the Handle (34) or set
down so that Lower Base (2) is free from
If the water level sinks too low, any 2.
sludge in the shaft will dry out and stop
the pump from starting. To help ensure
the pump will start as required, check the
pump regularly with start-up tests.
If the piping you install runs in excess 3.
of ten feet, it is recommended you use
a check valve (not included) to prevent
back flow, which could lead to rapid
cycling. To avoid air locks in the Pump,
drill a 1/8” hole in the piping between the
check valve and the Pump.
If you’re using a sump, the sump pit must 1.
have a minimum diameter of 11’’ and
max. depth of 10 ft.
Construct the sump pit using tile, plastic, 2.
concrete or steel.
Set the Pump on a brick or block slightly 3.
smaller than the pit. Fill pit with clean
1” stones to surround the lower half of
the Pump to keep it stable. The stones
should be large enough to not clog any
of the Pump’s inlets.
Install a sump cover to protect the Pump 4.
from falling debris.

The pump is equipped with a shock-1.
proof plug according to regulations. The
pump is designed to be connected to a
120 V~, 60 Hz GFCI outlet.
Make sure that the socket is sufficiently 2.
secured and is in excellent condition.
When the plug is inserted into the socket 3.
the pump will be on standby.
WARnIng! If the power cord or plug is
damaged, do not use the pump. The
power cord or plug may only be repaired
by a certified electrician.
note: This pump has a built-in thermal protec-
tor for the motor, which automatically shuts it
off to avoid overheating. After it cools, it will
cycle back on. Wait for the cycle to continue.
Do not try to turn on the pump manually after it
1. Plug unit into Ground Fault Circuit
2. The pump will automatically turn on
when the water level, or the sump,
has filled to approximately 3” above
the base. It will stop when the water
level drops below 3”. It will continue to
3. Check that the discharge water travels
several feet from the foundation.
Float Switch Adjustment
There is a Float Switch Lock (38) that is con-
nected to the Rear Cover (22). The Float
Switch cord snaps into the Float Switch Lock,
as shown in Figure 2 below. Adjust the level
that the Pump turns on by adjusting the length
of the Float Switch cord.
note: If air bubbles are spotted around the
handle or pressure switch, this is normal. It is
trapped air escaping from the unit. This pump
is equipped to remove air locks in the pump.
OPERATIOn: Unplug the Pump
from its electrical outlet before
performing any inspection,
maintenance, or cleaning
If the pump is moved during operation,
flush it out with clean water after every use.

The below maintenance must be
performed at least once every 3 months under
optimal conditions. For frequent use, more
frequent maintenance is required.

and any debris which clogs them
should be removed (Before performing
inlet cleaning, disconnect pump from
