comply with their rules.

3. Vent sewage or septic tank according to local codes.

4. Do not install pump in any location classified as

hazardous by National Electrical Code, ANSI/NFPA
70-1990.

Risk of electric shock. Can shock, burn

or kill. During operation, the pump is in water.
To avoid fatal shocks, proceed as follows if pump
needsservicing:

5A. Disconnect power to outlet box before

unpluggingpump.

5B. Take extreme care when changing fuses. Do not

stand in water or put your finger in fuse socket.

5C. Do not modify cord and plug. When using cord and

plug, plug into a grounded outlet only. When wiring
to a system control, connect pump ground lead to
system ground.

6.
Dry running can overheat pump (causing burns to
anyone handling it) and will void warranty.

7. Risk of burns. Pump normally runs hot.
To avoid burns when servicing pump, allow it to
cool for 20 minutes after shut-down before handling.

8. In normal service, motor should not need oiling.
Motor has been filled at the factory with a
specialoil.

NOTICE This unit is not designed as a waterfall or
fountain pump, or for applications involving salt water or
brine! Use with waterfalls, fountains, salt water or brine
will void warranty.

Risk of burns. Do not run pump dry.

Installation

See Figure 1 for typical installation instructions.

Risk of electric shock. Can shock, burn
or kill. Do not lift pump by power cord. See Cord Lift
Warning. Do not hang pump from discharge pipe or
power cord.

NOTICE Pump must be level when operating. If motor
is tilted, internal start/run switch may overheat and
damagemotor.

1. Install the pump on a solid, level foundation, or in

a sump pit constructed of tile, concrete, steel or
plastic. The recommended minimum diameter of the
sump pit is 18” (46cm) diameter and the minimum
recommended depth is 30” (76cm). Check local
codes for approved materials.

NOTICE Pump should not be installed on clay, earth

or sand surfaces. Clean the area around the pump of
small stones and gravel which could clog the pump.
Keep the pump inlet screen clear.

2. Thread a 2” discharge pipe into the pump 2” NPT

discharge port. Be careful to avoid stripping or
crossing threads.

Pi ping – Effluent Applications (3/4” or

Less Solids)

Piping must be 1-1/2” minimum to carry volume of
pump discharge. Check local codes to determine if a
check valve is required in your system. In cold climates,
check valves are not used to prevent effluent from
freezing in piping.

Pi ping – Sewage Applications (2” or

Less Solids)

In any case, piping must not be smaller than pump
discharge. When installed in a sewage system, pipe must
be capable of handling semi-solids of at least 2” (5.1 cm)
diameter.

The rate of flow in the discharge pipe must keep any
solids present in suspension in the fluid. To meet
minimum flow requirements (2 feet (.6 m) per second in
discharge line), size pipe as follows:

NOTICE Use PTFE tape on pipe connections. Do not
use ordinary pipe joint compound on plastic pipe or
pump. Pipe joint compound can attack plastics and
damagepump.

3. To reduce motor noise and vibrations, a short length

of rubber hose can be connected into discharge line
near pump using suitable clamps.

subfreezing atmosphere, then the portion of line
exposed must be installed so any water remaining in
pipe will drain to outfall by gravity. Failure to do this
can cause water trapped in discharge to freeze which
could result in damage to pump.

5. Install a 2” check valve in the horizontal portion of

the discharge pipe. Make certain, the flow indicating
arrow, points away from the pump. This check valve
will keep the water from either running back into the
basin or into the area being pumped out when the
pump is not running. Check valve should be a free
flow valve that will easily pass solids.

NOTICE For best performance of check valve when
handling solids, do not install it with discharge angled
more than 45° above the horizontal. Do not install check
valve in a vertical position as solids may settle in valve
and prevent opening on startup.

6. Drill a 3/16” (4.7mm) hole in discharge pipe

about 1”-2” (2.5 - 5.1cm) above pump discharge
connection (but below check valve) to prevent
airlocking the pump.

7. Insert the float switch piggy-back plug into a properly

grounded outlet and the pump plug into the piggy­back plug.

8. Check the installation by observing the pump

operation through one complete cycle. Make sure
that no parts of the assembly interfere with the
floatswitch.

Risk of flooding. Can cause personal injury
and/or property damage. Failure to make this operational
check may lead to improper operation, premature failure,
and flooding.

Electrical

Risk of electric shock. Can shock, burn or
kill. When installing, operating, or servicing this pump,
follow safety instructions listed below.

1. DO NOT splice the electrical power cord.

2. DO NOT allow electrical cord plug to

besubmerged.

3. DO NOT use extension cords. They are a fire hazard

and can reduce voltage sufficiently to prevent
pumping and/or damage motor.

4. DO NOT handle or service pump while it is

connected to power supply.

5. DO NOT remove grounding prong from plug or

modify plug.To protect against electrical shock, the
power cord is a three-wire conductor and includes
a 3-prong grounded plug. Plug pump into a 3-wire,
grounded, grounding-type receptacle. Connect pump
according to electrical codes that apply.

For parts or assistance, call Flotec Customer Service at 1-800-365-6832.

Operation • Service 4

For automatic operation, plug or wire pump into an
automatic float switch or pump controller. Pump will run
continuously when plugged directly into an electrical
outlet. Connect or wire pump to its own individual
branch circuit with no other outlets or equipment in
the circuit. Size fuses or circuit breakers according to
Specifications chart.

Risk of electric shock. Can shock, burn or
kill. Be sure that power supply information (Voltage/
Hertz/Phase) on pump motor nameplate matches
incoming power supply exactly. Install pump according
to all electrical codes that apply.

Operation

NOTICE Do not allow pump to run in a dry sump. It will
void the warranty and may damage the pump.

An automatic overload protector in the motor will protect
motor from burning out due to overheating/overloading.
When motor cools down, overload protector will
automatically reset and start motor.

If overload trips frequently, check for cause. It could be
a stuck impeller, wrong/low voltage, or electrical failure
in motor. If an electrical failure in the motor is suspected,
have it serviced by a competent repairman.

Pump is permanently lubricated. No oiling or greasing
isrequired.

Service

or kill. Before removing pump from basin for service,
always disconnect electrical power to pump and
controlswitch.

Risk of electric shock. Can shock, burn
or kill. Do not lift pump by power cord. See Cord Lift
Warning below.

Submerge pump in a disinfectant solution (dilute chlorine
bleach) for at least one hour before disassemblingpump.

The pump motor contains a special lubricating oil which
should be kept clean and free of water at all times.

Check operation by filling sump with water and
observing pump operation through one complete cycle.

Risk of flooding. Can cause personal injury
and/or property damage. Failure to make this operational
check may lead to flooding and premature failure.

NOTICE This unit is not designed for applications
involving salt water or brine! Use with salt water or brine
