INSTALLATION INSTRUCTIONS
330 Series Centrifugal, Lawn Sprinkler Pumps
PREINSTALLATION CHECKLIST - ALL INSTALLATIONS
1. Inspect all materials. Occasionally, products are damaged during shipment. If the unit is damaged, contact your dealer before using.
2. Carefully read all the literature provided to familiarize yourself with specific details regarding installation and use before attempting the
installation. These materials should be retained for future reference.

SEE BELOW FOR LIST OF WARNINGS
To help reduce the risk of electrical shock, a proper ground 7. Unit must be securely and adequately electrically grounded. This can be
accomplished by wiring the unit to a ground metal-clad raceway system or
or control box of grounding type must be installed and protected
by using a separate ground wire connected to the bare metal of the motor
by a ground fault circuit interrupter (GFCI) in accordance with the
frame or other suitable means.
National Electrical Code and applicable local codes.
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 a damp or wet area.
3. Make sure the pump’s electrical supply circuit is equipped with fuses
or circuit breakers of proper capacity. A separate branch circuit, sized
according to the National Electrical Code for the current shown on the pump
name plate is recommended.
4.
5.
6.
TESTING FOR GROUND. As a safety measure, electrical supply
should be checked for ground using an Underwriters Laboratory
Listed circuit analyzer which will indicate if the power, neutral and
ground wires are correctly connected . If they are not, call a qualified licensed
electrician.
Installation and checking of electrical circuits and hardware should
only be performed by a qualified licensed
electrician.
8.
Do not put a valve in the discharge line without automatic shut-off
capability. Failure to install an automatic shut-off (pressure switch
and tank) can allow the pump to run at no flow causing the pumped
liquid to overheat and cause steam burns.
9.
Risk of electric shock. This pump has not been investigated for
use in swimming pool areas.
10. 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.
NOTE: Repair and service should be performed by an Authorized Service Station
only (Consult factory).
NOTE: Pumps are designed to have a maximum static lift (suction head) of 25
feet (vertical distance from water surface to center line of pump).
NOTE: Pumps with the CSA CUS mark are tested to UL standard UL 778 and
certified to CSA standard C22.2 No. 108.
FOR YOUR PROTECTION ALWAYS DISCONNECT PUMP FROM
ITS POWER SOURCE BEFORE HANDLING. De-energize the
circuit at the control box. If the power point is out-of-sight, lock it
in the open position and tag it to prevent unexpected application of power.
Failure to do so could result in fatal electrical shock.
SEE BELOW FOR LIST OF CAUTIONS
1. Check to be sure your power source is adequate to handle the
amperage requirements of the motor as indicated on the pump or
unit I.D. tag.
3. Be certain the pump is completely primed before starting. Otherwise
damage may occur to the seal.
4.
2. All plumbing (discharge and intake lines) must be installed to
meet local codes.
Be careful when touching the exterior of an operating
motor - it may be hot enough to be painful or cause
injury.

LOCATION
1. Pump can be located at the well or can be offset some distance
away from the well. For best performance it should be located as
close to the well as possible.
2. Location can be in the basement, a watertight pit below ground, or
in a pump house above ground.
3. Ventilation and drainage must be provided to prevent damage from
moisture to the motor and pressure switch.
4. The pump and all piping must be protected from freezing.
5. Pump and pipe line must be drained when not in use if there is any
danger of freezing.
WELL CONDITIONS
1. Wells should be pumped clean of all sand and foreign matter
before installing the pump or damage may result to the operating
parts.
2. The well must be able of supplying enough water to satisfy the
capacity of the pump and water needs. The water level must not
draw down below the maximum rated suction lift of the pump or
loss of capacity and prime will result.
SUCTION LIMITATIONS
1. Shallow well installation is satisfactory where the suction lift is less
than 25 feet. Suction lift is the vertical lift plus losses due to friction
2. Suction lift varies depending upon elevation (altitude) and water
temperature.
PIPING
1. Plastic or galvanized steel pipe may be used in the installation.
Plastic pipe must have a minimum pressure rating 160 P.S.I. Galvanized steel pipe must be in good condition free of rust and scale.
Threads should be sharp and cleanly cut.
2. Both the suction and discharge pipe should be no smaller than the
corresponding tappings of the pump (See Figure 1). If long runs
are encountered larger pipe should be used. Smaller pipe will
reduce the capacity of the pump.
3. All joints and connections should have pipe sealing compound
(male threads only) applied and drawn up tightly.
Contact Zoeller Pump Company, 3649 Cane Run Road, Louisville, Kentucky 40211-1961, Attention: Customer Service Department to obtain
any needed repair or replacement of part(s) or additional information
pertaining to our warranty.
ZOELLER PUMP COMPANY EXPRESSLY DISCLAIMS LIABILITY
FOR SPECIAL, CONSEQUENTIAL OR INCIDENTAL DAMAGES
OR BREACH OF EXPRESSED OR IMPLIED WARRANTY; AND ANY
IMPLIED WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE
AND OF MERCHANTABILITY SHALL BE LIMITED TO THE DURATION
OF THE EXPRESSED WARRANTY.
This warranty gives you specific legal rights and you may also have
other rights which vary from state to state.
The entire system must be air and water tight for efficient operation.
PUMP INSTALLATION
1. Refer to Figures 3, 4, 5, and 6 for typical installations. If galvanized pipe is used, both the suction and discharge pipe should be
supported at a point near the pump to avoid strains being placed
on the pump.
2. The suction pipe should slope upwards from the water source
to the pump. Locate the pump as close to the water as possible
keeping the suction pipe as short as conditions permit.
3 Avoid dips or pockets in offset piping or air will accumulate at high
points which will make priming difficult.
4. A foot valve located in the water or a check valve located as close
to the water as possible will reduce priming time of the pump and
help maintain prime. A strainer must be used on the suction line to
filter out dirt and debris.
5. Install a gate valve and union in the discharge line. For removal
of the pump for service, close the gate valve and disconnect the
union.
Do not use a globe valve or other restricting type
of valve at the discharge. This will seriously restrict the capacity of the
pump.

ELECTRICAL CONNECTIONS
GROUNDING
CHECK VOLTAGE OF POWER
SOURCE BEFORE CONNECTING
To reduce the risk of electric shock the
motor must be securely and adequately grounded to a grounded metal
raceway system, or by using a separate grounding wire connected to
bare metal on the motor frame, or to the grounding screw located inside
motor terminal box, or other suitable means. Refer to National Electric
Code (NEC Article 250 {Grounding}) for additional information.)
All wiring should be performed by a
qualified electrician and in accordance with the national electric code
and local electric codes.
Failure to connect the motor frame to
equipment grounding conductor by using green screw may result in serious electrical shock.
WIRING CONNECTIONS
1. This unit is not water proof and is not intended to be used in
showers, saunas, or other potentially wet locations. The motor
is designed to be used in a clean dry location with access to an
adequate supply of cooling air. Ambient temperature around the
motor should not exceed 104F (40C). For outdoor installations
motor must be protected by a cover that does not block airflow to
and around the motor. This unit is not weatherproof nor is it able to
be submersed in water, or any other liquid.
2. Single phase motors, 3/4 - 2 HP, are dual voltage and can be connected for 115V or 230V service.
3. If the motor wiring must be changed to conform to your specific
voltage requirements then the motor should be rewired. For proper
electrical connections, refer to the connection diagram located on
the nameplate of the motor or the one in Figure 7. Make sure connections are correct for the voltage being supplied to the motor.

MOTOR PROTECTION
1. All motors have built-in thermal protection for all voltages. The
overload protects the motor against burnout from overload of low
voltage, high voltage and other causes. The device is automatic
and resets itself once the temperature has dropped to a safe point.
Frequent tripping of the device indicates trouble in the motor or
power lines and immediate attention is needed. The device should
never be tampered with unless the trouble is located and corrected.
2. Undersize wiring can cause motor failure (low voltage), frequent
cut-out of motor overload protector, television interference and
even fire. Make certain the wiring is adequately sized (Figure
9), well insulated and connected to a separate circuit outside the
house in case of fire.

2. After the pump is turned on it will require 2-5 minutes before all
air is evacuated from the suction line and water begins to flow. If
there is no water after 10 minutes turn the pump off and check the
following.
a. Any air leaks on the suction line must be eliminated.
b. Suction pipe inlet should be a minimum of 5 feet below the water
level.
c. Total suction lift cannot be greater than 25 feet.
d. Any restrictions in the discharge line, such as a closed valve
must be eliminated.
NOTE: Unit must be full of liquid before operating. Never run dry,
or against a closed discharge. Dry running or running unit against a
closed discharge will cause damage to the shaft seal. Do not pump
dirty water or abrasive liquids, otherwise the same may occur as if
running dry.
MOTOR ROTATION
Pumps are designed to rotate in one direction only, (counterclockwise
when facing the pump suction tapping) and cannot be reversed.
MAINTENANCE
Lubrication
The pumps and motors require no lubrication. The ball bearings of
the motor have been greased at the factory. Under normal operating
conditions they should require no further greasing.
Freezing
Drain the entire system if there is danger of freezing. A drain plug is
provided at the bottom of the pump case for this purpose.
ROTARY SEAL ASSEMBLY REPLACEMENT
Make certain that the power supply is
disconnected before attempting to service the unit!
The rotary seal assembly must be handled carefully
to avoid damaging the precision lapped faces of the sealing components.
See Parts List For Reference Numbers
1. Disengage pump body (Ref. No. 10) from motor and mounting ring

2. Remove diffuser bolts (Ref. No. 8) and remove diffuser (Ref. No.
7).
3. Unthread impeller (Ref. No. 6). from motor shaft.
NOTE: To remove the impeller use a 9/16" open end wrench to hold the
motor shaft. The shaft flat area is located in the middle of the mounting
ring.
4. The rotary seal (Ref. No. 5) will come loose at this time. Use a screwdriver (or similar instrument) to pry the ceramic seal and rubber gasket
from the recess of the mounting bracket.
Be careful not to damage the motor shaft or recess
surface.
5. Clean the recess and motor shaft thoroughly.
6. Install the new rotary seal assembly:
a. Insert the ceramic seal and the rubber gasket into the recess.
NOTE: To help facilitate installation, apply a light coating of oil to the
outside diameter of the rubber gasket. Make certain that the ceramic
seal is kept clean and free of dirt and/or oil.
b. Slip the remaining parts of the rotary seal assembly onto the
motor shaft.
7. Replace the impeller and diffuser removed in Step B and C.
8. Reassemble the pump body to the motor and mounting bracket.
MOTOR REPLACEMENT
1. NEMA J motors can be replaced in the field with any standard
NEMA J jet pump motor by referring to the following instructions
and the attached parts list.
2. Follow steps A-D as outlined under rotary seal replacement to
remove the pump body, diffuser, impeller and rotary seal.
3. Remove bolts (Ref. No. 3) that connect the motor (Ref. No.1) to
