1. Check to be sure your power source is capable of handling the voltage require-
ments 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
belowthecheckvalveandpitcovertopurgetheunitoftrappedair.Waterstream
will be visible from this hole during pump run periods. This vent hole should be
checkedperiodicallyforcloggingandcleanedasnecessary.Trappedairiscaused
by agitation and/or a dry basin.
4. Water hammer creates momentary high pressure surges. These surges can
causeseveredamageto check valves and thepipingsystem. Consideration for
water hammer must be included in the piping system design. ReferenceASPE
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 counter-
clockwise looking into impeller inlet. See page 4 for instructions for checking 3
phase rotation.
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 refer ence.
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 pos-
sibility of electrical shock.
3. Make certain that the control box is within the reach of the pump’s power
supplycord.DONOTUSEANEXTENSIONCORD.Extensioncordsthataretoolong
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. Makesurethepumpelectricalsupplycircuitisequippedwithfusesanddisconnect
or circuit breakers of proper capacity. Aseparatebranchcircuit 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.

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.
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.
Therotation is correct if the kick back is in the oppositedirectionofthe rotation arrow.Iftherotation is not correct, disconnect power and switch
any two power leads. Turn power back on and retest for proper rotation.
DOUBLE SEAL PUMPS
(1) Double seal pumps offer extra motion protection from damage caused by seal failure.
(2) Pumps should be serviced on a periodic preventative maintenance schedule.
(3) 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 contaminations, both seals should be replaced during maintenance.Always replace with new factory recommended oil and service
parts.All warranty repairs must be made by ZoellerAuthorized Service Stations.
CONTROL PANELS
These pumps are nonautomatic. They require a control panel.Amotor starter circuit, control circuit, and alarm circuit within the panel are stan-
dard 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) Allpumpsrequireoverloadprotectioninpanel.Usewithapprovedmotorcontrolthatmatchesmotorinputinfullloadampereswithoverload
element(s) selected or adjusted in accordance with control instructions.
(3) HazardousLocation pumps require panels that offerintrinsically safe relays and all other NEC requirements must be followed (SeeArticle
500,501 & 502 plus any others that apply.)
Pump Wiring Instructions
