electrician.
WARNING ! To reduce risk of electrical shock, pumps and
control panels must be properly grounded in accordance
with the National Electric Code (NEC) or the Canadian
Electrical Code (CEC) and all applicable state, province,
local codes and ordinances. Improper grounding voids
warranty.
WARNING! To reduce risk of electrical shock, always
disconnect the pump from the power source before
handling or servicing. Lock out power and tag.
WARNING! Operation against a closed
discharge valve will cause premature bearing
and seal failure on any pump, and on end
suction and self priming pump the heat build
may cause the generation of steam with resulting dangerous
pressures. It is recommended that a high case temperature
switch or pressure relief valve be installed on the pump body.
CAUTION ! Never operate a pump with a plug-in type
power cord without a ground fault circuit interrupter.
CAUTION ! Pumps build up heat and pressure
during operation-allow time for pumps to cool
before handling or servicing.
WARNING ! Do not pump hazardous materials
(flammable, caustic, etc.) unless the pump is specifically
designed and designated to handle them.
CAUTION ! Do not block or restrict discharge hose, as
discharge hose may whip under pressure.
WARNING ! Do not wear loose clothing that may
become entangled in moving parts.
WARNING ! Keep clear of suction and discharge
openings. DO NOT insert fingers in pump with power
connected.
Always wear eye protection when working on pumps.
Make sure lifting handles are securely fastened each
time before lifting. DO NOT operate pump without safety
devices in place. Always replace safety devices that
have been removed during service or repair. Secure the
pump in its operating position so it can not tip over, fall
or slide.
DO NOT exceed manufacturers recommendation for
maximum performance, as this could cause the motor
to overheat.
DO NOT remove cord and strain relief. DO NOT connect
conduit to pump.
WARNING ! Cable should be protected at all times to
avoid punctures, cut, bruises and abrasions. Inspect
frequently. Never handle connected power cords with
wet hands.
WARNING ! To reduce risk of electrical shock, all wiring
and junction connections should be made per the NEC
or CEC and applicable state or province and local
codes. Requirements may vary depending on usage
and location.
WARNING! Submersible Pumps are not approved for
use in swimming pools, recreational water installations
decorative fountains or any installation where human
contact with the pumped fluid is common.
WARNING! Products returned must be cleaned,
sanitized, or decontaminated as necessary prior to
shipment, to insure that employees will not be exposed
to health hazards in handling said material. All Applicable
Laws And Regulations Shall Apply.
Bronze/brass and bronze/brass fitted pumps may
contain lead levels higher than considered safe for

SECTION B: GENERAL INFORMATION
B-1) To The Purchaser:
Your new Submersible Pump is constructed of the best
available materials and is designed to give you many years
of service with a minimum of attention.
This manual will provide helpful information concerning
installation, maintenance, and proper service guidelines.
Check local codes and requirements before installation.
Servicing should be performed by knowledgeable pump
service contractors or authorized service stations.
The pump is packaged ready for installation and no
connections or adjustments are necessary except for
attaching discharge piping and plugging in service cord.
B-2) Receiving:
Upon receiving the pump, it should be inspected for
damage or shortages. If damage has occurred, file a claim
immediately with the company that delivered the pump.
If the manual is removed from the crating, do not lose or
misplace.
SECTION C: INSTALLATION
C-1) Location:
These pumping units are self-contained and are
recommended for use in a sump or basin. This pump is
designed to pump effluent or wastewater, nonexplosive
and noncorrosive liquids and shall NOT be installed in
locations classified as hazardous in accordance with
the National Electrical Code (NEC), ANSI/NFPA 70 or the
Canadian Electrical Code (CEC).
The sump or basin shall be vented in accordance with local
plumbing codes. The float switch should not come in con-
tact with side or bottom of sump. Make sure sump is free
of string, cloth, nails, gravel, etc. before installing pump.
Never install the pump in a trench, ditch, or hole with a dirt
bottom where the suction will become plugged.
C-1.1) Submergence:
The pump should always be operated in the submerged
condition. The minimum sump liquid level should never be
less than 4.50 inches (114mm) above the pump bottom.
The recommended level should not drop below the top of
the motor housing (See Figure 2).
FIGURE 2
Testing is performed with water, specific gravity of 1.0 @ 68° F, other fluids may vary performance

5
C-2) Discharge:
Discharge piping should be as short as possible. The
installation of a check valve in the discharge piping is
recommended for each pump being used. The check valve
is used to prevent backflow into the sump. Excessive
backflow can cause flooding and/or damage to the pump.
C-3) Liquid Level Controls:
Figure 3 shows a typical installation for a submersible
pump using a piggy-back wide angle level control mounted
to the discharge piping with a Piggy-Back plug.
General Comments:
1) Never work in the sump with the power on.
2) Level controls are factory set for a pumping differential
of 9 inches (228.6mm). If that is the cycle desired, simply
circle the discharge pipe with the pipe mounting strap, feed
the end through the worm drive, and tighten with a screw-
driver. Be certain that the level control cannot hang up or
foul in it’s swing. Also, make certain the pump impeller is
still submerged when the level control is in the ‘off’ mode.
3) If a higher pump differential is needed, grip the cord
near the neck of the float, then using the other hand, exert
a steady force on the lower edge of the cable clamp. The
cable clamp should slide up to the new pivot point. Attach
the level control to the discharge hose in the manner
described above.
4) Plug the level control plug into a GFI receptacle, then
plug the pump into the piggyback plug. One cycle of op-
eration should be observed , so that any potential prob-
lems can be corrected.
5) It is recommended that the float should be set to insure
that the sump well liquid level never drops below the top
of the motor housing or a minimum level of 4.50 inches
above the pump bottom.
Figure 4 shows a typical connection for pumps with the
piggy-back plug, for manual and automatic operations.
Automatic - Plug float cord into GFI outlet, then plug
pump cord into float cord.
Manual - Plug pump cord directly into GFI outlet.
C-4) Electrical Connections:
C-4.1) Power Cable:
The cord assembly mounted to the pump must not be
modified in any way. This pump comes complete with
a 3 wire cord and 3 prong grounded plug that must be
connected into a 3 wire grounded Ground Fault receptacle.
DO NOT remove ground pin from electrical plug. It is NOT
recommended to use an extension cord with these pumps.
DO NOT USE THE POWER CABLE TO LIFT PUMP.
WARNING! - THE WHITE WIRE IS NOT A
NEUTRAL OR GROUND LEAD, BUT A POWER
CARRYING CONDUCTOR.
C-4.2) Overload Protection:
Automatic thermal overload protects the sealed-in-oil
motor. Running dry may overheat the motor and trip the
overload. The type of in-winding overload protector used
is referred to as an inherent overheating protector and
operates on the combined effect of temperature and
current. This means that the overload protector will trip
out and shut the pump off if the windings become too hot,
or the load current passing through them becomes too
high. It 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 rectified immediately. DO NOT LET THE
PUMP CYCLE OR RUN IF AN OVERLOAD CONDITION
OCCURS !

Wire Size:
Consult a qualified electrician for proper wire size if addi-
tional power cable length is required. See table for electri-
cal information.
SECTION: D START-UP OPERATION
D-1) Check Voltage and Phase:
Before operating pump check to make sure that the voltage
and phase information stamped on the pump’s identifica-
tion plate matches the available power.
D-2) Check Pump Rotation:
Before putting pump into service for the first time, the motor
rotation must be checked. Improper motor rotation can result
in poor pump performance and can damage the motor and/
or pump. To check the rotation, suspend the pump freely,
momentarily apply power and observe the “kickback”.
“Kickback” should always be in a counter-clockwise direction
as viewed from the top of the pump (“kickback” is always
opposite to impeller rotation). “Rotation” and “kickback”
direction is noted on the pump motor housing.
D-3) Identification Plate:
Record the numbers off the pump’s identification plate
onto manual for future reference.
D-4) Pump-Down Test:
After the pump has been properly wired and lowered into
the basin, sump, or lift station, it is advisable to check the
system by filling with liquid and allowing the pump to operate
through it’s pumping cycle. The time needed to empty the
system, or pump-down time, should be recorded.
SECTION E: PREVENTATIVE MAINTENANCE
As the motor is oil filled, no lubrication or other maintenance
is required, and generally will give very reliable service and
can be expected to operate for years on normal sewage
pumping without failure. However, as with any mechanical
piece of equipment a preventive maintenance program
is recommended and suggested to include the following
checks:
1) Inspect motor chamber for oil level and contamination
2) Inspect impeller and body for excessive build-up or
clogging.
E-1) Lubrication:
Anytime the pump is removed from operation and at least
every twelve (12) months, the cooling oil in the motor
housing (11) must be checked visually for oil level and
contamination.
E-1.1) Checking Oil:
To check oil, set unit upright. Remove pipe plug. With a
flashlight, visually inspect the oil in the motor housing to
make sure it is clean, clear and that the oil level is above
all internal componentry. If oil appears satisfactory, replace
pipe plug. If oil is low or appears contaminated, test oil as
per section E-1.2
E-1.2) Testing Oil:
1. Place pump on it’s side, remove pipe plug and
drain oil into a clean, dry container.
2. Check oil for contamination using an oil tester with
a range to 30 kilovolts breakdown.
3. If oil is found to be clean and uncontaminated
(measures above 15 KV. breakdown), refill the
motor housing as per section E-1.3.
4. If oil is found to be dirty or contaminated
(or measures below 15KV. breakdown), then the
pump must be carefully inspected for leaks at the
shaft seal (1), cord inlet (2), square ring and pipe
plug before refilling with oil. After leak is repaired,
refill with new oil as per section E-1.3.
F-1.3 Replacing Oil in Motor Housing:
Drain all oil from motor housing and dispose of properly.
Refill with 32 ounces (.9 liters) of new cooling oil as per Table
1. An air space must remain in the top of the motor housing
to compensate for air expansion. Set unit upright and fill only
until oil level from top of pipe plug boss is 3” ± 1/4” (76.2mm
± 6.35mm).
WARNING ! - DO NOT overfill oil. Overfilling of
motor housing with oil can create excessive
and dangerous hydraulic pressure which
can destroy the pump and create a hazard.
Overfilling oil voids warranty.

G-1 SHAFT SEAL SERVICE
Disconnect power, remove screws and lockwashers, and
vertically lift motor assembly from body. Clean out body if
necessary. Clean and examine impeller for pitting or wear.
The impeller is threaded onto the shaft and to remove,
unscrew impeller, holding shaft with a large screwdriver.
CAUTION: - Handle seal parts with extreme
care. DO NOT scratch or mar lapped surfaces.
To expose shaft seal (1) disassemble volute and impeller
as outlined in above paragraph. Remove rotating member
(1b) from shaft (See Fig. 5). Examine all seal parts and
especially contact faces. Inspect seal for signs of wear such
as uneven wear pattern on stationary members, chips and
scratches on either seal face. DO NOT interchange seal
components, replace the entire shaft seal (1). If replacing
seal, remove stationary (1a) by prying out with flat screw
driver.
Clean and oil seal cavities in lower motor housing. Lightly oil
(DO NOT use grease) outer surface of stationary member
(1a). Press stationary member (1a) firmly into lower motor
housing, using a seal pusher, nothing but the seal pusher
is to come in contact with seal face (See Fig. 6).
IMPORTANT ! - DO NOT hammer on the seal
pusher- it will damage the seal face.
Make sure the stationary member is in straight. Slide a bullet
over motor shaft. Lightly oil (DO NOT use grease) shaft,
bullet and inner surface of bellows on rotating member (1b)
See Fig. 7. With lapped surface of rotating member (1b)
facing inward toward stationary member (1a), slide rotating
member (1b) over bullet and onto shaft, using seal pusher,
until lapped faces of (1a) and (1b) are together (See Fig.
5).
It is extremely important to keep seal faces clean during
assembly. Dirt particles lodged between these faces will
cause the seal to leak. Place spring (1b) over shaft and in
place on rotating member (1c), making sure it is seated.
Slide retaining ring (1a) over shaft and let rest on spring
(1b).
Before installing impeller, inspect threads on shaft and
impeller to assure that they are clean. Apply a thread
locking compound to shaft threads and screw impeller
onto shaft and tighten. Rotate impeller to check for binding.
Install motor housing assembly on pump body. Apply thread
locking compound to each cap screw, thread into body with
lockwashers, and torque to 11 ft. lbs. Check for free rotation
of impeller. Assemble impeller and volute, replace oil.
