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 suspended from the handle
or be placed on the bottom of the basin.
To ensure that the pump works properly, keep the
bottom free from sludge and dirt of all kinds.
2. If the water level sinks too low, any sludge in the
basin 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.
Power Supply
1. The pump is equipped with a shock-proof plug
according to regulations. The pump is designed to be
connected to 120 VAC, 60 Hz GFCI protected socket.
2. Make sure that the socket is sufficiently
secured and is in excellent condition.
3. When the plug is inserted into the socket,
the pump will be on standby.
4. WARNING: To prevent death from electric
shock, pump must be connected only to
a GFCI protected outlet.
WARNING! TO PREVENT SERIOUS INJURY:
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.
Areas of use
1. This pump is designed to pump water only.
2. This pump is designed to be used for:
Irrigation systems, lawn sprinkling,
and clear water transfer.
3. This pump should NOT be used for:
Continuous run, fountain/pond water features.
Water with dirt and debris. Removing water from
swimming pools or spas. Septic or sewage systems.
4. This pump can also be used to transfer water
(e.g. household, farming, plumbing).

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).

4. Remove the Inlet and Outlet Covers from the Pump.
5. 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.
6. Install a foot valve and filter (sold separately)
at the bottom of the inlet.

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

Operation
After reading these instructions, consider the following points before starting the pump:
1. Verify that the discharge pipe is properly connected.
2. Verify that the electrical connection
is 120 VAC, 60 Hz.
3. Verify that the electrical socket is GFCI
protected and in good condition. Test
GFCI protected outlet before use.
4. Verify that water and moisture cannot
get near the power supply socket.
5. Verify that the pump is installed so
as to prevent running dry.
6. To start the pump:
a. Open the valve on outlet side of the Y-fitting.
b. Make sure your hands are dry.
c. Plug in the pump.
d. Turn on the Power Switch (I).
e. Close the valve on the priming side of the Y-fitting.
NOTICE: Do not run the Pump Dry!
Turn off the Pump IMMEDIATELY if water
stops coming out 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), 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.
If the pump is moved during operation, flush it out with clean water after every use.
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.
1. Clean sludge and debris from the bottom of the basin.
2. Clean sludge/debris from inlet screen.
3. Make sure discharge pipe is free from leaks.
4. Make sure check valve is functioning properly.
5. Manually operate flow switch to determine
that pump turns on/off as intended.
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.
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.
