REFER TO WARRANTY ON PAGE 2.
CAUTION
SEE BELOW FOR
LIST OF CAUTIONS
SEE BELOW FOR
LIST OF WARNINGS
1. Do not lift, carry, or hang pump by the electrical cables. Damage to
the electrical cables can cause shock, burns or death.
2. Make sure there is a properly grounded receptacle available.
All pumps are furnished with provisions for proper grounding to help
protect you against the possibility of electrical shock.
3. Make certain that the receptacle is within the reach of the pump’s
power supply cord. DO NOT USE AN EXTENSION CORD. Extension
cords that are too long or too light do not deliver sufcient voltage to
the pump motor. But, more important, they could present a safety
hazard if the insulation were to become damaged or the connection
end were to fall into the sump.
4. Make sure the pump electrical supply circuit is equipped with
fuses or circuit breakers of proper capacity. A separate branch
circuit is recommended, sized according to the “National Electrical
Code” for the current shown on the pump nameplate.
5. FOR ADDED SAFETY. Pumping and other electrical equipment
must be connected to a 3-prong grounded receptacle with integral
ground-fault circuit interrupter (GFCI).
6. Risk of electric shock - These pumps have not been investigated
for use in swimming pool areas.
7. According to the state of California (Prop 65), this product contains
chemicals known to the state of California to cause cancer and birth
defects or other reproductive harm.
1. Check to be sure your power source is capable of handling the voltage
requirements of the motor, as indicated on the pump nameplate.
2. The installation of pumps using auxiliary variable level oat switches
is the responsibility of the installing party and care should be taken
that the tethered oat switch will not hang up on the pump apparatus
or pit peculiarities and is secured so that the pump will shut off. It
is recommended that rigid piping and ttings be used and the pit
be 36” or larger in diameter.
3. INFORMATION - VENT HOLE PURPOSE. It is necessary that all
submersible sump, efuent, and sewage pumps capable of han-
dling various sizes of solid waste be of the bottom intake design to
reduce clogging and seal failures. If a check valve is incorporated
in the installation, a vent hole (approx. 3/16”) must be drilled in the
discharge pipe below the check valve and pit cover to purge the
unit of trapped air. Trapped air is caused by agitation and/or a dry
basin. This vent hole should be checked periodically for clogging
and cleaned as necessary. Water stream will be visible from this
hole during pump run periods.
4. Water hammer creates momentary high pressure surges. These
surges can cause severe damage to check valves and the piping
system. Consideration for water hammer must be included in the
piping system design. Reference ASPE Data Book, Chapter 2.33.
Some systems may require external spring or lever weighted check
valves or other engineered solutions.

FOR YOUR PROTECTION, ALWAYS DISCONNECT PUMP FROM ITS POWER SOURCE BEFORE HANDLING. Single phase
pumps are supplied with a 3-prong grounded plug to help protect you against the possibility of electrical shock. DO NOT UNDER ANY CIRCUMSTANCES
REMOVE THE GROUND PIN. The 3-prong plug must be inserted into a mating 3-prong grounded receptacle. If the installation does not have such
a receptacle, it must be changed to the proper type, wired and grounded in accordance with the National Electrical Code and all applicable local codes and
ordinances.
All three phase pumps require motor starting devices with motor overload protection. See FM0514 for simplex installations or FM0486 for duplex
installations. Three phase pumps must be installed in accordance with the National Electrical Code and all applicable local codes and ordinances. Pumps are
not to be installed in locations classied as hazardous in accordance with National Electrical Code, ANSI/NFPA 70.
“Risk of electrical shock” Do not remove power supply cord and strain relief or connect conduit directly to the pump.
Installation and checking of electrical circuits and hardware should be performed by a qualied licensed electrician.
Pump Wiring Instructions
Single Phase Installation
Models E404/E405 and I404/I405 are nonautomatic. To operate automati-
cally a control panel or 20 amp control switch (P/N 10-0748) must be added
to the power circuit. Follow the instructions provided with the panel or oat
switch to wire the system.
WD Model Installation
Models WD404/WD405 are fully automatic. A oat switch is included and factory wired in the pump circuit to
provide automatic operation once the oat switch is secured properly to the outlet pipe. Use the diagram above to

Three phase pumps are nonautomatic. To operate automatically, a control
panel is required. Follow the instructions provided with the panel to wire the
system.
Before installing a pump, check the pump rotation to insure that wiring has
been connected properly to power source, and that the green lead of power
cord (See wiring diagram), is connected to a valid ground, Momentarily en-
ergize the pump, observing the directions of kick back due to starting torque.
Rotation is correct if kick back is in the opposite direction of rotation arrow on
the pump casing. If rotation is not correct, switching of any two power leads
other than ground, should provide the proper rotation.
Determining Pumping Range
in Inches (1 inch - 2.5 cm)
min. max.
Use only as a guide. Due to weight of
cable, pumping range above horizontal
is not equal to pumping range below

Operation
GENERAL
Zoeller pumps are lubricated and tested at the factory prior to shipment and
require minimum pre-start-up maintenance.
Maximum continuous operating temperature of pump liquid for standard model
pumps must not exceed 130° F (54° C). WD models pump liquid should not
exceed 120° F (49° C). Nonautomatic pumps and pumps with adjustable
level controls must be totally submerged on long pumping cycles. A maximum
of ½ hour run time per hour.
These units are not designed to handle liquids other than water or sewage. If
pump is used in water contaminated with heavy, viscous, or abrasive materials,
the warranty will be voided.
NAMEPLATE DATA
The nameplate, located on the top of pump, indicates specic information about
the construction of the pump. The model number and date code information
should be recorded on the front page in the “Owner’s Information” section of
this manual.
SHORT TERM STORAGE
If pump is to be stored for more than six months, the following is advised:
• Store pump inside whenever possible or cover with some type of protective
covering.
• Tape or seal in plastic bag the terminal ends of wire leads.
• Spray coat unpainted surfaces with rust inhibiting oil.
• The impeller should be rotated every six months in order to keep the seals
lubricated and not develop a permanent set.
If panel is to be stored for more than six months, the following is advised:
• Store the panel inside whenever possible and leave in the shipping box.
• All openings shall be sealed.
• Store in an upright position.
• Do not stack anything on top of panel.
STARTUP PROCEDURE
Before placing the equipment into operation the following checked:
• Correct pump rotation (3 Phase units only).
• Clean pit.
• Panel dry and securely installed.
• Floats positioned properly.
• Discharge valves open.
• 3/16” vent hole drilled in pipe between check valve and pump.
Once the above has been veried proceed with the following checks:
• Pump power cables properly connected to panel.
• Float cables properly connected to panel.
• Conduit connections to panel are properly sealed.
• Thermal overload adjustments made in the panel.
• After installing the pump into the containment area, with adequate sub-
mergence, open the discharge valve fully. Start the unit using manual
controls. If ow is appreciably less than rated performance, pump may
be air locked. To expel trapped air, jog the unit several times, using the
manual controls.
• Have a qualied electrician take voltage and current measurements on
the black wire of single phase or all three power wires of three phase with
the pump running. Record these readings in the space provided in the
“Owner’s Information” section of this manual for future reference.
After the preoperational functional test has been completed, system is ready
for operation. Zoeller recommends completing a Start-up Report (FM0990)
whenever a system is started for the rst time or after a system has had a
signicant change take place (i.e. pump replacement, overhaul, ect.). A copy
of the Start-up Report should remain with the system for future reference.
ADJUSTMENT PROCEDURE
Pumps: No adjustments are required other than assuring correct rotation.
Panels: The thermal overloads in the panel (3 Ph systems) must be set
to the F.L.A. rating on the pump nameplate (or refer to pump data
sheet).
Floats: Refer to the system drawing for desired location of each oat
function.
Valves: Discharge valves should be placed in the fully open position. Sys-
tems should not be operated for extended periods of time with the
discharge valves partially closed due to damaging the valve.
SHUTDOWN PROCEDURES
If a system is shutdown for more than six months, the following is
recommended:
Pumps: If pit is to remain dry, then the pump can remain in the pit. With the
pump in the pit, it should be operated for ve minutes once every
three months. If the pit is to remain wet, the pump should be removed
and stored as noted below.
Panels: The panel should have all openings sealed to prevent moisture and
dust from entering the enclosure. Prior to restarting system, the
panel should be inspected for presence of moisture and any loose
connections.
Valves: Consult the valve/actuator supplier for information concerning these
systems components (used on dewatering pump stations only).
Maintenance
Repair and service should be performed by a Zoeller Pump
Company Authorized Service Station only.
SAFETY PROCEDURES
For your protection, always disconnect pump and panel from
its power source before handling.
Never enter the basin until it has been properly vented and
tested. Any person entering a basin should be wearing a harness with safety
rope extending to the surface so that they can be pulled out in case of asphyxi-
ation. Sewage water gives off methane and hydrogen sulde gases, both of
which can be highly poisonous.
Installation and checking of electrical circuits and hardware should be performed
by a qualied electrician.
Pump is never to be lifted by power cord.
Unit must be ushed and disinfected, inside and out, prior
to servicing.
GENERAL SYSTEM INSPECTION
Before the system is placed into operation, a system Start-up Report should
be conducted by a qualied technician.
Wiring and grounding mustbe in accordance withthe national
electrical code and all applicable local codes and ordinances.
LUBRICATION PROCEDURES
No lubrication is required.
If pumps are to be stored for more than six months, refer to short term storage
procedure in the Operation section.
PREVENTIVE MAINTENANCE
Preventive maintenance is recommended to ensure a long service life from
the product. Provided is a suggested maintenance schedule.
Every month:
• Check for proper and unobstructed oat operation.
• Listen for proper check valve operation.
• Activate pumps and take voltage and amperage readings.

both seals should be replaced during maintenance. Always replace with
new factory recommended oil and service parts. All repairs must be made
by Zoeller Authorized Service Stations.
