to regulations. The plug must have a supply voltage of 115 VAC at 60 Hz.
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. This pump has been evaluated
for use with water only.
4. The electrical connections must be
protected from moisture.
5. If there is danger of flooding, the electrical
connections must be taken to higher ground.
6. Circulation of caustic fluids, as well as the circulation
of abrasive materials, must be avoided at all costs.
7. The pump must be protected from frost.
8. The pump must be protected from running dry.
9. Access by children should also be
prevented with appropriate measures.
10. To prevent death from electric shock,
pump must be connected only to a GFCI
protected outlet.
11. Do not use an extension cord with this item.
12. 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.

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

Installation
The submersible motor 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 of the basin 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 a
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 be used for:
• Removing ground water from
basements and crawlspaces.
• Pumping grey water residential systems.
2. This pump should NOT be used for:
• Continuous run, fountain/pond water features.
• Removing water from swimming pools or spas.

Installation Instructions
1. Construct a basin that is at least 22″deep
and at least 14″in diameter.
Figure A: Sewage Basin
2. Position Pump on solid surface so that the Float
Switch is away from the inlet pipe and at least 1"
away from all obstructions throughout its movement.
3. Fit a sewage cover with a vent pipe, a hole for the
output pipe and a hole for the Power Cord. Thread
the Power Cord through the hole, but do not plug
it in yet. Set the sewage cover aside for now.
4. Attach a discharge pipe to the Pump Outlet.
Drill a 1/8″diameter air bleed hole through the
discharge pipe just above the lower Base to prevent
Pump ″airlock.″A small spray of water out of
this hole is normal while the Pump is running.
Note: Wrap all threaded connections
with PTFE thread seal tape.
Float
Figure B: Discharge Pipe and Pump
5. To prevent excessive cycling from backflow of
water, install a check valve (not included) onto
the discharge pipe. This prevents water from
flowing back after the pump shuts off. Install
according to manufacturer’s instructions. Mount
the check valve according to check valve label
to avoid the valve flapper getting stuck.
Figure C: Pump Setup
6. Connect additional discharge pipe as needed to
direct the discharge to the main waste line for the
sewer or septic tank. The discharge should be kept
as short as possible with a minimum number of turns.
7. Make sure that Float is able to move freely.
8. Secure power supply cord to discharge pipe
to prevent possible switch entanglement.
IMPORTANT: Do not exceed the Maximum
Head Lift @ 0 GPH Flow of the Pump.

Operation
1. After reading these instructions, consider the
following points before starting the pump:
a. Verify that the pump rests on the floor of the basin.
b. Verify that the discharge pipe
is properly connected.
c. Verify that the electrical connection
is 115 VAC, 60 Hz.
d. Verify that the electrical socket is GFCI
protected and in good condition. Test
GFCI protected outlet before use.
e. Verify that water and moisture cannot
get near the power supply socket.
f. Verify that the pump is installed so
as to prevent running dry.
2. Connect pump power supply cord to GFCI outlet.
3. Fill sump basin with water. Pump will
automatically start when water level reaches
certain level. Pump will automatically turn
off if water falls below a certain level.
4. After filling with water, secure sewage cover and
gasket to basin to prevent debris from falling into
basin.
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. Soak in bleach solution for 2 hours after removing from service
before handling. Wear ANSI-approved splash-resistant safety goggles, full face shield, and impermeable rubber work
gloves during service.
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.
