Receiving Inspection
Upon receiving the pump, it should be
inspected for damage or shortages.
If damage has occurred, le a claim
immediately with the company that
delivered the pump. If the manual is
removed from the packaging, do not
lose or misplace.
Storage
Any product that is stored for a period
longer than six (6) months from the
date of purchase should be bench
tested prior to installation. A bench
test consists of, checking the impeller
to assure it is free turning and a run
test to assure the motor (and switch
if provided) operate properly. Do not
pump out of liquid.
Controls
Manual models require a separate
approved pump control device or panel
for automatic operation. Be sure the
electrical specication of the control
selected properly match the electrical
specications of the pump.
Submergence
The pump should always be operated in
the submerged condition. The minimum
sump liquid level should never be less than
above the pump’s volute (See Figure 1).
Installation
These pumps are recommended for
use in a sump, basin or lift station.
The sump, basin or lift station shall be
sealed and vented in accordance with
local plumbing codes. This pump is
designed to pump sewage, euent
or wastewater, nonexplosive and
noncorrosive liquids and shall NOT
be installed in locations classied as
hazardous in accordance with the
National Electrical Code (NEC) ANSI/
NFPA 70 or Canadian Electric Code
(CEC). The pump should never be
installed in a trench, ditch, or hole with
a dirt bottom. The legs will sink into
the dirt and the suction will become
plugged.
The installation should be at a sucient
depth to ensure that all plumbing is
below the frost line. If this is not feasible,
remove the check valve and size the
basin to accommodate the additional
backow volume.
Pumps are most commonly installed
in simplex or duplex stations or basins
with a slide rail system, which allows
the pump(s) to be installed or removed
without requiring personnel to enter
the station, or resting on the basin oor.
Discharge Piping
Discharge piping should be as short
as possible and sized no smaller than
the pump discharge. Do not reduce
the discharge pipe size below that
which is provided on the pump. Both
a check valve and a shut-o valve are
recommended for each pump. The
check valve is used to prevent backow
into the sump. The shut-o valve is
used to manually stop system ow
during pump servicing.
Liquid Level Controls
The level control(s) should be mounted
on the discharge piping, a cable rack
or oat pole. The level control should
have adequate clearance so it cannot
hang up in it’s swing and that the pump
is completely submerged when the
level control is in the “O” mode. By
adjusting the cord tether the control
level can be changed. One cycle of
operation should be observed, so that any
potential problems can be corrected.
It is recommended that the level control
oat should be set to insure that the liquid
in the sump never drops below the top of
the motor housing or a minimum level of
10 inches above the basin oor.
Electrical Connections
Power cable:
The power cable mounted to the pump
must not be modied in any way except
for shortening to a specic application.
Any splice between the pump and the
control panel must be made in
accordance with the electric codes. It is
recommended that a junction box, if used,
be mounted outside the sump or be of
at a minimum Nema 4 construction if
located within the wet well. DO NOT USE
THE POWER CABLE TO LIFT PUMP.
Always rely upon a Certied Electrician
for installation.
Overload Protection:
Single Phase - The stator in-winding
overload protector used is referred to
as an inherent overheating protector
and operates on the combined eect
of temperature and current. This means
that the overload protector will trip out
and shut the pump o if the windings
become too hot, or the load current
passing through them becomes too high.

IMPORTANT ! - The overload will then
automatically reset and start the pump
up after the motor cools to a safe
temperature. In the event of an overload,
the source of this condition should be
determined and corrected immediately.
WARNING! - DO NOT LET
THE PUMP CYCLE OR RUN IF
AN OVERLOAD CONDITION
OCCURS !
If current through the temperature sensor
exceeds the values listed, an intermediate
control circuit relay must be used to
reduce the current or the sensor will not
work properly.

Wire Size:
If longer power cable is required consult
a qualied electrician for proper wire
size.
Pre-Operation
1. Check Voltage and Phase - Compare
the voltage and phase information
stamped on the pump name plate.
2. Check Pump Rotation - Improper
motor rotation can result in poor
pump performance and can damage
the motor and/or pump. Check
rotation on three phase units by
momentarily applying power and
observe the “kickback”.
Kickback should always be in a
counter-clockwise direction as
viewed from motor end or opposite
to impeller rotation. Incorrect rotation
for Single-Phase pumps is unlikely.
If the rotation is incorrect contact
factory.
3. Name Plate - Record the information
from the pump name plate to
drawing in front of manual for future
reference.
4. Insulation Test - An insulation
(megger) test should be performed
on the motor. Before the pump is put
into service. The resistance values
(ohms) as well as the voltage (volts)
and current (amps) should be
recorded.
5. Pump-Down Test - Be sure pump
has been properly wired, lowered into
the basin, sump or lift station, check
the system by lling with liquid and
allowing the pump to operate through
its pumping cycle. The time needed to
empty the system, or pump-down
time along with the volume of water,
should be recorded.
Maintenance
No lubrication or maintenance is required.
Perform the following checks when pump
is removed from operation or when pump
performance deteriorates:
a). Inspect motor chamber for oil level
and contamination.
b). Inspect impeller and body for
excessive build-up or clogging.
c). Inspect motor, bearings and shaft seal
for wear or leakage.
Servicing
NOTE: Item numbers in ( ) refer to Figures
6 through 9.
Cooling Oil - Anytime the pump is
removed from operation, the cooling oil
in the motor housing should be checked
visually for oil level and contamination.
To check oil, set unit upright. Remove
pipe plug (20) from housing (4). With a
ashlight, visually inspect the oil in the
housing (4) to make sure it is clean and
clear, light amber in color and free from
suspended particles. Milky white oil
indicates the presence of water. Oil level
should be just above the motor when
pump is in vertical position.
Oil Testing
• Drain oil into a clean, dry container by
placing pump on it’s side, remove pipe
plug (20), from housing (4).
• Check oil for contamination using an
oil tester with a range to 30 Kilovolts
breakdown.
• If oil is found to be clean and
uncontaminated (measuring above
15 KV. breakdown), rell the housing.
• If oil is found to be dirty or
contaminated (or measures below
15 KV. breakdown), the pump must
be carefully inspected for leaks at the
shaft seal, cable assembly, square ring
and pipe plug, before relling with oil. To
locate the leak, perform a pressure test.
After leak is repaired, dispose of old oil
properly, and rell with new oil.
Pressure Test (If oil has been drained)
Remove pipe plug (20) from housing (4).
Apply pipe sealant to pressure gauge
assembly and tighten into hole. Pressurize
motor housing to 10 P.S.I. Use soap
solution around the sealed areas and
inspect joints for “air bubbles”.

If, after ve minutes, the pressure is still
holding constant, and no“bubbles”are
observed, slowly bleed the pressure and
remove the gauge assembly. Replace
oil. Leek must be located and repaired if
pressure does not hold.
Pressure Test (If oil has NOT been
drained) - Oil should be at normal level.
Remove pipe plug (20) from housing (4).
Apply pipe sealant to pressure gauge
assembly and tighten into hole. Pressurize
motor housing to 10 P.S.I. Use soap
solution around the sealed areas above
the oil level and inspect joints for“air
bubbles”. For sealed areas below oil level,
leeks will seep oil. If, after ve minutes,
the pressure is still holding constant, and
no “bubbles”/oil seepage is observed,
slowly bleed the pressure and remove the
gauge assembly. Replace oil. Leek must be
located and repaired if pressure does not
hold.
Pressure builds up extremely
fast, increase pressure by
“TAPPING” air nozzle. Too much
pressure will damage seal. DO
NOT exceed 10 P.S.I.
Oil Replacement - Set unit upright and
rell with new cooling oil as per table
below . Fill to just above motor, but below
capacitor as an air space must remain in
the top of the housing to compensate
for oil expansion. Apply pipe thread
compound to threads of pipe plug (20)
then assemble to housing (14.
DO NOT overll oil. Overlling
of housing with oil can create
excessive and dangerous hydraulic
pressure which can destroy the
pump and create a hazard.
Overlling oil voids warranty.

Trouble Shooting Chart
Risk of electric shock. Always disconnect the pump from the power source before handling inspections or repairs.
Symptom Possible Cause(s) Corrective Action
Pump will not run
1. Poor electrical connection, blown fuse, tripped
breaker or other interruption of power;
improper power supply
2. Motor or switch inoperative (go to manual
operation)
2a. Float movement restricted
2b.Switch will not activate pump or is defective
2c. Defective motor
3. Insucient liquid level
1. Check all electrical connections for security.
Have electrician measure current in motor leads,
if current is within ± 20% of locked rotor Amps,
impeller is probably locked. If current is 0,
overload may be tripped. Remove power, allow
pump to cool, then re-check current.
2a. Reposition pump or clean basin as required to
provide adaquate clearance for oat
2b.Disconnect level control. Set ohmmeter for a
low rang, such as 100 ohms full scale and
connect to level control leads. Actuate level
control manually and check to see that
ohmmeter shows zero ohms for closed switch
and full scale for open switch. (Float Switch)
2c. Check winding insulation (Megger Test) and
winding resistance. If check is outside of range,
dry and re-check. If still defective, replace per
service instructions.
3. Make sure liquid level is above the pump
4. Re-check all sizing calculations to determine
proper pump size.
5. Check discharge line for restrictions, including
ice if line passes through or into cold areas.
6. Remove and examine check valve for proper
installation and freedom of operation
7. Open valve
8. Check impeller for freedom of operation,
security and condition. Clean impeller cavity
and inlet of any obstruction
9. Loosen union slightly to allow trapped air to
escape. Verify that turn-o level of switch is set
so that the suction is always ooded. Clean vent
hole
10. Check rotation. If power supply is three phase,
reverse any two of three power supply leads to
ensure proper impeller rotation
11. Repair xtures as required to eliminate leakage
12. Check pump temperature limits and uid
temperature
13. Replace portion of discharge pipe with exible
connector or tighten existing piping.
14. Turn to automatic position
15. Check for leaks around basin inlet and outlets
Pump will not turn o
2a. Float movement restricted
2b.Switch will not activate pump or is defective
4. Ecessive inow or pump not properly sized for
application
9. Pump may be air locked causing pump not to ow
14. H-O-A switch on panel is in“HAND” position
Pump hums but doesn’t run
1. Incorrect low voltage
8. Impeller jammed or loose on shaft, or inlet
plugged
Pump delivers insucient capacity
1. Incorrect low voltage
4. Ecessive inow or pump not properly sized for
application
5. Discharge restricted
6. Check valve partially closed or installed backwards
7. Shut-o valve closed
8. Impeller jammed or loose on shaft, or inlet
plugged
9. Pump may be air locked causing pump not to ow
10. Piping xtures leaking or discharge before the
nozzle
Pump cycles too frequently or runs periodically
when xtures are not in use
6. Check valve partially closed or installed backwards
11. Fixtures are leaking
15. Ground water entering basin
Pump shuts o and turns on independent of
switch, (trips thermal overload protector).
CAUTION! Pump may start unexpectedly.
Disconnect power supply.
1. Incorrect low voltage
4. Ecessive inow or pump not properly sized for
application
8. Impeller jammed or loose on shaft, or inlet
plugged
12. Excessive water temperature (internal
protection only)
Pump operates noisily or vibrates excessively
2c. Worn bearings, motor shaft bent
5. Debris in impeller cavity or broken impeller
10. Pumprunning backwards
13. Piping attachments to building structure too
loose or rigid
