WARNING
IMPORTANT! For your own safety –
before starting to run the Pump, please have
the following items checked by an expert:
1. Risk of electric shock – This Pump is supplied
with a grounding conductor and grounding-type
attachment plug. To reduce the risk of electric shock,
be certain that it is connected only to a properly
grounded, grounding-type receptacle.
2. Risk of electric shock – This Pump has not been
investigated for use in swimming pool areas.
3. The electrical connections must be
protected from moisture.
4. If there is danger of flooding, the electrical
connections must be taken to higher ground.
5. Circulation of caustic fluids, as well as the circulation
of abrasive materials, must be avoided at all costs.
6. The Pump must be protected from frost.
7. The Pump must be protected from running dry.
8. Access by children should also be
prevented with appropriate measures.
9. To prevent death from electric shock,
Pump must be connected only to a
GFCI-protected outlet.
10. Do not use an extension cord with this item.
11. People with pacemakers should consult their
physician(s) before use. Electromagnetic fields in
close proximity to heart pacemaker could cause
pacemaker interference or pacemaker failure.
12. The warnings, precautions, and instructions
discussed in this instruction manual cannot cover all
possible conditions and situations that may occur.
It must be understood by the operator that
common sense and caution are factors
which cannot be built into this product, but
must be supplied by the operator.

Installation
The Pump must be installed in a stationary position with either:
a. A fixed pipeline or
b. A flexible hose pipe.
Please note!
1. Do not install the Pump by suspending it
unsupported from its delivery pipe or power cord.
The Pump must be installed on a solid surface.
2. If the source water level sinks too low, unit will
begin pumping air and overheat. Operating
the Pump without an adequate water supply
will damage the Pump and voids warranty.
Power Supply
1. The Pump is equipped with a shock-
proof plug according to regulations. The
Pump is designed to be connected to a

Installation Instructions
1. Position Pump on solid surface.
WARNING! TO PREVENT SERIOUS INJURY: This is
NOT a submersible pump. Do not immerse in water.
2. The Pump uses 1" NPT piping (sold separately).
Purchase the necessary length of pipe, including
any needed fittings 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. Wrap all threaded
connections with PTFE tape (sold separately).

3. Remove the Inlet and Outlet Covers from the Pump.
4. Attach the water source to the Inlet, using appropriate
methods. The Inlet hose or pipe must be collapse-
proof to properly withstand the suction force.
5. Install a foot valve and filter (sold separately)
at the bottom of the inlet.

6. Attach the outlet connection to the Outlet.
A Y-fitting with dual valves (sold separately) is
helpful for priming the Pump. Refer to Figure B.
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.
7. Connect a bucket full of at least 3 gallons of water
to one side of the Y-fitting using a hose, as shown in
Figure B. (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.
8. Close the valve on the outlet side of the Y-fitting, and
open the valve on the priming side of the Y-fitting.
9. Remove the Priming Plug and wait until water
starts coming out of the Priming Plug. Replace
the Priming Plug and tighten securely.

NOTICE: Do not run the Pump Dry!
Turn off the Pump IMMEDIATELY if water
stops coming out of the Outlet.
7. 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.
8. After the Pump is running properly, the priming
hose and bucket can be disconnected.
9. When finished using the Pump, turn the
Power Switch off (O), dry your hands, then
unplug the Power Cord. Follow procedures
for storage explained on the next page.

Maintenance
TO PREVENT SERIOUS INJURY FROM ACCIDENTAL OPERATION:
Unplug the Pump from its electrical outlet before performing any
inspection, maintenance, or cleaning procedures.
1. BEFORE EACH USE, inspect the
general condition of the Pump. Check for:
• loose hardware
• misalignment or binding of moving parts
• cracked or broken parts
• damaged electrical wiring
• 
• any other condition that may
affect its safe operation.
2. AFTER USE, wipe the Pump clean with a soft,
damp cloth with soapy water. Do not use solvents.
Do not get the electrical components wet.
3. If the Pump sits idle for a period of 5 days or more, it
should be unplugged and rotated several revolutions
using a screwdriver through the middle hole of the
Fan Cover to prevent it from taking a permanent set.
4. If the Pump is used only occasionally, when
pumping is complete disconnect both suction
and outlet lines, tip Pump to drain water
from Pump cavity, and replace the Inlet
and Outlet Covers to protect the unit.
Quarterly Maintenance
The below maintenance must be performed at least once every 3 months under optimal conditions.
For frequent use, or dirty areas, more frequent maintenance is required.

2. Make sure discharge pipe is free from leaks.
3. Make sure foot valve is functioning properly.
4. Check that the water source and piping
are clear of sand, dirt and debris.
Long Term Storage
1. Drain Pump body. Disconnect both suction and
outlet lines, then tip Pump so that all water is
drained from Pump cavity. Replace the Inlet
and Outlet Covers and apply light machine
oil to metal parts to prevent corrosion.
2. Store the Pump in a dry, indoor area
out of reach of children.
