To reduce risk of electrical
shock:

Risk of Electrical Shock:

This pump has not been
investigated for use in swimming
pool areas.

1. This pump is supplied with
a grounding conductor and
ground ing-type attachment
plug. To reduce risk of
electrical shock, be certain
that it is connected only
to a properly grounded,
grounding-type receptacle.

2. Septic tank is to be vented
in accordance with local
plumbing codes.

3. Do not smoke or use spark­able electrical devices or
flame in a septic (gaseous) or
pos si ble septic sump.

4. A septic sump condition may
exist and if entry into sump is
necessary, then (1) provide
proper safety precautions
per OSHA requirements and
(2) do not enter sump until
these precautions are strictly
adhered to.

5. Do not install pump in location
classified as hazardous per
N.E.C., ANSI/NFPA 70 - 2001.

Fail ure to heed above cau­tions could result in injury or

2. Make sure float (automatic
models) hangs free. It should
not come into contact with
side or bottom of sump pit.

3. Make sure sump is free of
string, cloth, nails, gravel, etc.
before in stall ing pump.

4. Do not set pump directly on
the bottom of sump if it is
not solid. Raise the pump by
placing bricks or concrete
blocks un der neath it.

5. Use steel or plastic pipe for
all connecting lines be tween
pump and sewer outlet.

NOTICE Some city regulations
do not allow in stall ing a pump
with plastic pipe. Check local
reg u la tions.

6. A check valve should be
installed in dis charge pipe, at
least twelve inches above the
discharge outlet of the pump.

7. Connect to power source
using 3-prong grounded
115/230 volt AC receptacle.
Do not remove ground pin
from elec tri cal plug. Do not
use an ex ten sion cord.

8. For proper automatic
operation make sure the pump
power cord is plugged into
the back of the “pig gy back” re­cep tacle on the switch cord.

9. Use pump submerged for
pumping waterlike liquids
(temperature to 120° F).

2

CAUTION: Do not pump
flam ma ble liquids, strong
chemi cals or salt water.

10. In applications where the
pump may sit idle for months
at a time, it is recommended
that the pump(s) be cycled
every few months to ensure
the pumping system is working
properly when needed.

Capacity, US GPM

Servicing should be per formed
only by an authorized service
center.

WARNING: Always disconnect
the pump from power source
before handling or making any
adjustments. Always wear rubber
boots when there is water on the
floor and you must unplug the
pump or make any ad just ments.

NOTICE Automatic thermal
overload protects the sealed­in-oil motor. Running dry may
overheat the motor and activate
the overload protector until the
unit cools.

Pump does not run or just
hums.

1. Line circuit breaker may be
off, blown or loose.

2. Water level in sump may be
too low to activate automatic
float or diaphragm switch.

3. Pump and/or switch cord plug
may not be making contact in
receptacle.

4. If pump is using the series
(piggyback) cord plug,
the two plugs may not be
plugged tightly together.

5. Float may be stuck. Be sure
float operates freely in basin.

6. If the unit is being operated
by the optional float control
switch, unplug the pump from
the pig gy back receptacle and
plug the pump directly into
the power source.
If the pump starts each time

it is plugged directly into the
receptacle and does not start
each time when plugged
into the piggyback switch
with the float raised up to
a start position, replace the
complete piggyback switch
assembly and retest with new
assembly.

7. If all symptoms check OK,
motor winding may be open;
take to authorized service
center for check.

Pump runs but does not
deliver water.

1. Check valve may be installed
backward. Arrow on valve
points in direction of flow.

2. Discharge gate valve, if used,
may be closed.

3. Pump may be air locked.
Start and stop several times
by plugging and unplugging
cord. Check vent hole in
pump case for plugging.

Pumps have a small air vent

hole in the impeller cavity
to let out trapped air. If this
hole becomes plugged, pump
may air lock. To break the air
lock, use a small screwdriver
to clear hole in the impeller
cavity.

As a secondary precaution

in installations of this type —
1 ⁄16” hole should be drilled in
the discharge pipe below the
check valve. The check valve
should be 12 to 18 inches
above pump discharge. Do
not put check valve directly
into pump discharge opening.

NOTICE In sumps where the
pump is operating daily, air
locking rarely occurs.

4. Pump head may be too
high. Pump cannot deliver
water over 25’ vertical lift.
Horizontal distance does not
affect pumping, except for
friction loss through the pipe.

5. Inlet in pump base may be
clogged. Remove pump and
clean out openings.

6. Impeller or volute openings
may be plugged or partially
plugged. Re move pump and
clean out.

Pump runs and pumps out
sump but does not stop.

1. Float is stuck in up position.
Be sure float is not hung up
and operates freely in basin.

2. Switch contacts may be
stuck; replace switch.
