PREINSTALLATION CHECKLIST - ALL INSTALLATIONS
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 plug in the cover.
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. To reduce the risk of electrical shock, a properly grounded receptacle or control box
must be installed in accordance with the governing codes. Never remove ground pin
from plug.
2. 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 sufficient voltage to the pump motor. But more important,they could
present a safety hazard if the insulation were to become damaged.
3. Make sure the pump's electrical supply circuit is equipped with fuses or circuit breakers
of proper capacity. A separate branch circuit is recommended, sized according to the
governing electrical codes for the current shown on the pump name plate.
4. Testing for ground. As a safety measure, each electrical outlet should be checked
for ground using a circuit analyzer which will indicate if the power, neutral and ground
electrician.
5. FOR YOUR PROTECTION, ALWAYS DISCONNECT PUMP FROM ITS POWER
SOURCE BEFORE HANDLING. If pump is wired direct, de-energize the circuit at the
control box. DO NOT, UNDER ANY CIRCUMSTANCES, REMOVE THE GROUND
PIN. Wear insulated protective shoes and do not stand in water. Pumps equipped
with a grounded plug are designed to help protect against electrical shock. A properly
grounded receptacle or control box must be installed in accordance with governing
codes.
6. Installation and servicing of the pump's electrical circuits and hardware should only be
7. Installation and maintenance of this appliance is not intended for persons (including
children) with reduced physical, sensory or mental capabilities, or lack of experience
or knowledge, unless they have been given supervision or instruction concerning use
of the appliance by a person responsible for their safety.
8. Risk of electrical shock. Do not remove power supply cord and strain relief or connect
conduit directly to the pump. If the supply cable is damaged, it must be replaced by an
authorized Zoeller Representative.
9. Pump may contain oil which becomes pressurized and hot when operating.
Allow 2-1/2 hours after disconnecting before attempting service.
10. Pump is not intended for potable water due to possible contamination by oil contained
in the pump.
11. Risk of electric shock. These pumps have not been investigated for use in swimming
pools and marine areas.

1. This unit is not designed to handle any material larger than the pump's solids-passing
ability.
• Model 49 and the 70 and 80 series pumps are designed to pass 9 mm (3/8" )
spherical solids.
• 50 and 90 series,140, 371, 372 model pumps are designed to pass 12 mm
(1/2") spherical solids.
• 130 series pumps are designed to pass 15 mm (5/8 ") spherical solids.
• 145 and 373 models and the 150, 160 and 180 series pumps are designed to
pass 19 mm (3/4") spherical solids.
• 422, 4290 series pumps are designed to pass 37 mm (1-1/2") spherical solids.
• 200 series sewage pumps are designed to pass 50 mm (2") spherical solids.
2. Check to be sure your power source is capable of handling the voltage requirements
of the motor, as indicated on the pump name plate.
3. All plumbing (discharge and vent lines) must be installed to meet local codes. Unit must
be vented. DO NOT USE AN AUTOMATIC PLUMBING VENT DEVICE SIMILAR TO A
"PROVENT". Some states require this product to be installed by a licensed plumber.

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 5 mm (3/16") vent hole must be drilled in the discharge pipe below the check
valve and pit cover to purge the unit of trapped air. Vent hole should be checked
periodically for clogging. The vent hole on a High Head application may cause too
much turbulence. You may not want to drill one. If you choose not to drill a vent hole,
be sure the pump case and impeller is covered with liquid before connecting the pipe
to the check valve. NOTE: THE HOLE MUST BE BELOW THE BASIN COVER AND
CLEANED PERIODICALLY. Water stream will be visible when pump is operating.
6. Pump should be checked frequently for debris and/or build up which may interfere
7. Maximum operating temperature for standard model pumps must not exceed 54 °C
(130 °F) for cast iron pumps, or 40 °C (104 °F) for pumps with plastic motor housings.
8. Do not operate a pump in an application where the Total Dynamic Head is less than
the minimum Total Dynamic Head listed on the Pump Performance Curves.
9. For health reasons, do not unplug, turn off, or disable pump and use pump tank system
10. CHECK VALVE MUST BE USED TO REDUCE UNNECESSARY CYCLING OF PUMP.
11. This system must be installed above the water table. Groundwater outside the basin will
cause it to collapse.
