Preinstallation Information
Electrical Data
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 oat switches must be connected to an intrinsically safe circuit in the control
panel. The installation of 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" (91.4 cm) or
larger in diameter.
3. INFORMATION - VENT HOLEPURPOSE.Itisnecessarythatallsubmersiblepumps
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" (4 mm)] 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.
6. 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
conned space requirements.
1.
Inspect your pump. Occasionally, products are damaged during shipment. If the unit is damaged, contact your distributor 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 specic details regarding installation and use. These materials should be retained for future reference.
3. National Electrical Code (NEC) articles 500 through 503 explain in detail the requirements for the installation and wiring of electrical equipment in hazardous locations.
1. Not for use in acidic atmospheres.
2. Do not lift, carry, or hang pump by the electrical cables. Damage to the electrical cables
can cause shock, burns or death.
3. Makesurethere isaproperlygroundedconnection available. Allpumpsare furnished
with provisions for proper grounding to help protect you against the possibility of electrical
shock.
4. 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 sufcient voltage to the pump motor. But, more importantly, they could present
a safety hazard if the insulation were to become damaged or the connection end were to
fall into the sump.
5. Make sure the pump electrical supply circuit is equipped with fuses and disconnect
orcircuitbreakersofpropercapacity. Aseparate branch circuit is recommended, sized
according to the “National Electrical Code” for the current shown on the pump nameplate.
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.
8. Electrical wiring and protection must be in accordance with the National Electrical Code
per NEC articles 500 through 503 for installation in Class
I , Division 1, Group C & D
environments, and any other applicable state and local electrical requirements.

Pump Wiring Instructions
Installation and checking of electrical circuits and hardware should be performed by a qualied 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 oat 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.
SENSOR CABLE
The sensor cable is the smaller cable, which contains 5 wires. The red and orange wires connect to the thermal cut-out circuit and the black and white wires
connect to the seal leak probes. The green wire is a ground connection. All 5 wires must terminate in the control panel.
The following should be noted:
(1) The thermal sensors are normally closed and mounted adjacent to the motor windings. If internal temperatures exceed a maximum limit, the pump will
deactivate when the red and orange wires are connected in series to the control coil of the motor starter circuit. The pump is able to restart once the motor
cools down. Continued deactivation of this circuit requires the attention from maintenance personnel.
(2) The black and white seal leak wires are connected to a 330K ohm circuit in the seal cavity, where 2 seal leak probes are housed. An indicator light will
activate whenever water is present in the cavity. Whenever the seal leak light is activated, indicating that the lower seal has failed, the pump should be
removed and serviced in order to avoid damage to the motor.
(3) The green wire shall be connected to a ground lug in the panel.
CONTROL PANELS
These pumps require a control panel. The control panel rarely requires an explosion proof rating since it is usually located outside the hazardous area. A motor
starter circuit, control circuit, and alarm circuit within the panel are standard features. Outdoor enclosure ratings and alternating relays are often required. Vari-
able level oat switches are the most common level sensing device.
The following should be noted:
(1) Float switch connections must be intrinsically safe.
(2) Single phase units have externally mounted capacitors and starting relays. Your control panel should have provisions for mounting these starting compo-
nents.
(3) The seal failure sensor and thermal sensor protection shall be incorporated into the panel.
(4) 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.
(5) Hazardous Location pumps require panels that offer intrinsically safe relays and all other NEC requirements must be followed (See Article 500, 501, 502
& 503 plus any others that apply.)

Three Phase Installation
Three phase pumps are nonautomatic. To operate automatically, a
control panel with level control is required. Follow the instructions
provided with the panel to wire the system.
Before installing a pump, check the pump rotation to ensure 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.
Refer to the wiring diagram supplied with specic electrical control
panel for correct electrical cable termination locations.
NOTE 1: Sensor cable includes 5 leads; 2 leads for thermal sensor, 2 leads for
moisture sensor, and a green ground lead. Sensor wire colors are as shown.

disassembled or repaired by a rm not certied to work on explosion
proof motors, the explosion proof rating is void and the FM and CSA
approval tag MUST BE REMOVED FROM THE PUMP.
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
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 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 oat operation.
• Listen for proper check valve operation.
• DuplexUnits-Checkforevenoperatingtimes.Uneventimesindicatea
defective unit, oat 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 oat switches.
Every year:
• In addition to the monthly checks, the basin should be inspected and
cleaned. Any defective components should be replaced. Inspect and
removeany sand,debris,ormudpresent inthepumpbasinassembly.
Every two years:
• 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 and Warranty Center.
DOUBLE SEAL PUMPS
• Double seal pumps offer extra protection. During every inspection of
the unit, check the control panel seal failure for a warning. Whenever
the seal leak is activated, indicating that the lower seal has failed, the
pump should be removed and serviced in order to avoid damage to
the motor.

Operation
GENERAL
Zoeller pumps are lubricated and tested at the factory prior to shipment and
require minimum pre-start-up maintenance.
Maximum liquid temperature of a continuous operating pump liquid for this
model pump must not exceed 104 °F (40 °C). For longest service life all pumps
should be totally submerged on long pumping cycles. Maximum submerged depth
is 50' (15.2 m).
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, date code, and serial number
information should be recorded on the front page in the “Owner’s Information”
section of this manual.
If the pump is repaired in the eld, its explosion
proof rating may be voided.
SHORT TERM STORAGE
If pump is to be stored, the following is advised:
• Storepumpinsidewheneverpossibleorcoverwithsometypeofprotectivecovering.
• 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 should be checked:
• Correct pump rotation (3 Phase units only).
• Clean pit.
• Panel dry, securely installed and properly sealed.
• Floats positioned properly.
• Discharge valves open.
• 3/16” (4 mm) 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 in an intrinsically safe 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 submer-
gence, 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
pumprunning.Recordthesereadingsinthespaceprovidedinthe“Owner’s
Information” section on page 1 of this manual for future reference.
Afterthepreoperationalfunctionaltesthas been completed, system isreadyfor
operation. Zoeller requires completing a Start-up Report (ZM1074) 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, 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 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
threemonths.If the pitistoremainwet, the pumpshouldberemoved
and stored as noted above.
Panels: The panelshouldhave allopenings sealed toprevent moistureand 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.
