10. Do not use an extension cord with this item.

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.

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 120 VAC, 60 Hz GFCI protected socket.

4.

2. Make sure that the socket is sufficiently
secured and is in excellent condition.

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.

3. When the plug is inserted into the socket,
the pump will be on standby.

WARNING: To prevent death from electric
shock, pump must be connected only to
a GFCI protected outlet.

Areas of use
1. This pump is designed to be used for:

2. This pump should NOT be used for:

Pumping domestic sewage, effluent, wastewater,
groundwater and other nonexplosive,
noncorrosive liquids with up to 2″ diameter
solids to gravity-fed sewage line

Continuous run, fountain/pond water features.
Removing water from swimming pools or spas.

Installation Instructions
1. Construct a basin that is at least 30″ deep
and at least 18″ in diameter.

Sewage
Basin

at least 30″ deep

Inlet Pipe

2. Position Pump on solid surface so that both
hoses are free from kinks 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 cords.
Thread the Power Cords through their holes,
but do not plug them in yet. Set the
sewage cover aside for now. Place unused
end of discharge hose the other end
Note: The sewage cover must also
be fitted with a vent pipe.

4. Attach a discharge pipe to the Pump Outlet.
Note: Wrap all threaded connections
with PTFE thread seal tape.
5. Check Valve is sold separately. Install
according to manufacturer instructions.
6. To prevent excessive cycling from backflow of water,
install a check valve onto the discharge pipe. This
prevents water from flowing back after the pump
shuts off. Mount the check valve according to check
valve label to avoid the valve flapper getting stuck.

Figure C: Outlet Pipe and Plug
IMPORTANT: 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.
7. 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.
IMPORTANT: Do not exceed the
Maximum Head Lift @ 0 Flow of the Pump.

Operation
After reading these instructions, consider the following points before starting the pump:
1. Verify that the pump rests on the floor of the basin.
2. Verify that the discharge pipe is properly connected.

4. Verify that the electrical socket is GFCI
protected and in good condition. Test
GFCI protected outlet before use.

3. Verify that the electrical connection
is 120 VAC, 60 Hz.

5. Verify that water and moisture cannot
get near the power supply socket.
6. Verify that the pump is installed so
as to prevent running dry.

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.

Item 63323

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.
