Preinstallation Information
1. Inspect your pump. Occasionally, products are damaged during shipment. If the unit is damaged, contact your dealer before using. DO NOT remove the test plugs in
the cover nor the motor housing.
2. Carefully read the literature provided to familiarize yourself with specific details regarding installation and use. These materials should be retained for future reference.
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 connection 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 control box 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 sufficient 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 and
disconnect 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. Care should be taken during the initial installation to be sure that adequate
air supply is available whenever any person is in the basin. Always follow OSHA
guidelines on confined space requirements.
6. Risk of electric shock - These pumps have not been investigated for use in swimming
pool areas.
SEE BELOW FOR
LIST OF CAUTIONS
CAUTION
SEE BELOW FOR
LIST OF WARNINGS
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 float switches is the
responsibility of the installing party and care should be taken that the tethered
float 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
fittings be used and the pit be 36” or larger in diameter.
3. INFORMATION - VENT HOLE PURPOSE. It is necessary that all submersible
pumps capable of handling 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. Water stream
will be visible from this hole during pump run periods. This vent hole should be
checked periodically for clogging and cleaned as necessary. Trapped air is caused
by agitation and/or a dry basin.
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.
5. Three phase pumps must be connected for proper rotation, which is counterclockwise looking into impeller inlet. See page 5 for instructions for checking 3
phase rotation.

Pump Wiring Instructions
Installation and checking of electrical circuits and hardware should be performed by a qualified licensed electrician.
“Risk of electrical shock” Do not remove power supply cord and strain relief or connect conduit directly to the pump.
CAUTION
Power cords, sensor cords, and float cords all must be sealed to prevent gases from the basin entering the control panel.
INSTRUCTIONS FOR CHECKING ROTATION OF THREE PHASE UNITS
It is very important that these units be connected for proper rotation. Since no rotating parts are visible without removing the pump from the pit,
the rotation on 3 phase units should be checked before installation into the pit as follows:
After the proper electrical connections are made, momentarily energize the pump observing the direction of kick back due to starting torque. The rotation is
correct if the kick back is in the opposite direction of the rotation arrow. If the rotation is not correct, disconnect power and switch any two power leads. Turn
power back on and retest for proper rotation.
THERMAL SENSOR PROTECTION
Two thermal sensors and leads are wired in series with each other and located adjacent to the motor windings. When the temperature exceeds the maximum
recommended limit, the pump will deactivate when the lead wires are connected to the magnetic starter circuit of a control panel with the thermal cutout feature.
Continual deactivation of this circuit requires attention from maintenance personnel.
MOISTURE SENSORS
(1) Pumps with moisture sensors have a separate sensor cord in addition to the power cord.
(2) Sensor cord conductors are connected to sensors probes in the lower seal cavity. The conductor wires are terminated in the control panel for activating
an indicator light when moisture is present in the lower seal cavity.
(3) When the moisture indicator light is activated, the lower seal has allowed leakage of water into the lower oil-filled seal cavity. The pump should be serviced
within 30 days to avoid damage to the motor and bearings.
(4) Oil in the motor housing and lower seal cavity must be checked when pump is serviced. If oil from the motor housing contains water or other contamination,
both seals should be replaced during maintenance. Always replace with new factory recommended oil and service parts. All warranty repairs must be
made by Zoeller Authorized Service Stations.
(5) On existing applications where the control panel only has one moisture sensor hookup per pump, one moisture sensor lead from the pump should be
hooked to the moisture sensor lead in the panel, the other moisture sensor lead from the pump should be hooked to ground to complete the circuit.
(6) Moisture sensor circuit can be checked for continuity (complete circuit) with a (Volt-OHM-Meter). Set the VOM to read resistance and connect the VOM
leads to the sensor cord black and white wires. The VOM should read approximately 330k Ohms. Resistance readings significantly lower indicate a seal
leak with water in the seal chamber. If VOM reading is open then a problem exists with moisture sensor circuit.
Check resistance between the green ground conductor of the pump power cord and the sensor cord black and white wires. This resistance reading should
indicate an open circuit. If VOM reading returns a reading other than open, then a problem exists with the sensor circuit wiring or cordage. If resistance
readings show a problem with either test, then pump should be repaired by a Zoeller Authorized Service Station.
CONTROL PANELS
These pumps are nonautomatic. They require a control panel. A motor starter circuit, control circuit, and alarm circuit within the panel are standard features. Outdoor enclosures and alternating relays are often required. Variable level float switches are the most common level sensing device. The following should be noted.
(1) Single phase units have externally mounted capacitors and starting relays. Your control panel should have provisions for mounting these starting
components.
(2) A pump incorporating the seal failure sensor and thermal sensor protection require that interfacing terminals and functions be incorporated into the panel.
(3) All pumps require overload protection in panel. Use with approved motor control that matches motor input in full load amperes with overload element(s)
selected or adjusted in accordance with control instructions.
(4) Hazardous Location pumps require panels that offer intrinsically safe relays and all other NEC requirements must be followed (See Article 500,501 & 502
plus any others that apply.)

Single Phase Installation
All single phase models require start capacitor, run capacitor and relay in the circuit to start and operate properly. These components can be purchased separately
or prewired in Zoeller control panel. For components purchased separately used the diagram for installation and hookup.
Single phase models are nonautomatic. To operate automatically a control panel must be added to the power circuit. Follow the instructions provided with the panel.

Three Phase Installation
TYPICAL 3-PHASE WIRING DIAGRAM
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 energize 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.

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 140° F (40° C). For longest service life all pumps should be
totally submerged on long pumping cycles and 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 specific information about
the construction of the pump. The model number, date code, and serial number
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, 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, 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.
START-UP 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 verified 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 submergence, open the discharge valve fully. Start the unit using manual controls.
If flow 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 qualified 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 on page 1 of this manual for future reference.
After the preoperational functional test has been completed, system is ready for
operation. Zoeller requires completing a Start-up Report (ZM1074) whenever a
system is started for the first time or after a system has had a significant change
take place (i.e. pump replacement, overhaul, etc..). 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 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 float
function.
Valves: Discharge valves should be placed in the fully open position. Systems
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 five minutes once every
three months. If the pit is to remain wet, the pump should be removed
and stored as noted above.
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.
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 asphyxiation.
Sewage water gives off methane and hydrogen sulfide gases, both of which
can be highly poisonous.
Installation and checking of electrical circuits and hardware should be performed
by a qualified electrician.
Pump is never to be lifted by power cord.
Unit must be flushed 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 qualified technician.
Wiring and grounding must be in accordance with the 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 float operation.
• Listen for proper check valve operation.
• Duplex Units - Check for even operating times. Uneven times indicate a
defective unit, float switch or control.
• Inspect the panel for any presence of moisture in enclosure, loose connections, and
general component condition. check out location and condition of float switches.
Every year:
• In addition to the monthly checks, the basin should be inspected and cleaned.
Any defective components should be replaced. Inspect and remove any sand,
debris, or mud present in the pump basin assembly.
Every two years:
• Check insulating oil in motor and seal chambers. Inspect oil for contaminations
as follows:
• Clear oil, no burnt odor - Oil, motor and seals are in satisfactory condition.
• Dark oil, burnt odor - Pump motor has overheated. Check the motor winding resistance
to ground. Ohm readings of 1 megohm or higher is required. If lower readings are
present, return the unit to an Zoeller Authorized Service Station for service.
• Milky, emulsified oil - Seals have failed. Unit must be returned to an authorized
service facility for service.
• Dispose of the motor insulating oil properly if replacement is required.
• Inspect power cables for damage or wear. Replace immediately if damage
or wear is detected.
• Inspect impeller for damage or wear. Replace as required by a Zoeller Authorized Service Station.
DOUBLE SEAL PUMPS
• Double seal pumps offer extra protection from damage caused by seal
failure.
• Oil in a motor housing and lower seal cavity must be checked when pump is
serviced. If oil from the motor housing contains water or other contamination,
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.
