PREINSTALLATION CHECKLIST - ALL INSTALLATIONS

1. Inspect all materials. Occasionally, products are damaged during shipment. If the unit is damaged, contact your dealer before using. DO NOT remove the test
plugs from the pump.
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 ground fault interrupter protected receptacle or 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, and 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 is recommended, sized
according to the local 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 wires are correctly connected to your outlet. If they are
not, call a qualified, licensed 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. Wear insulated protective shoes and do not stand in water.
Pumps equipped with a 3-prong ground plug are designed to help protect
against electrical shock. DO NOT, UNDER ANY CIRCUMSTANCES, REMOVE
THE GROUND PIN.
6. Installation and servicing of the pump's electrical circuits and hardware should
only be performed by a qualified, licensed electrician.
7. Risk of electrical shock. Do not remove power supply cord and strain relief or
connect conduit directly to the pump.
8. Pump contains oil which becomes pressurized and hot when operating. Allow
2-1/2 hours after disconnecting before attempting service.
9. Pump is not intended for potable water due to possible contamination by oil
contained in the pump.
10. Risk of electric shock. These pumps have not been investigated for use in
swimming pools and marine areas.

CAUTION
1. This unit is not designed to handle any material other than human waste and
toilet paper. The list of items that should not be used with this system includes,
but is not limited to, feminine sanitary products, condoms, cotton balls and
swabs, baby wipes, paper towels, etc.
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. The installation of 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 to use rigid pipe and fittings and
the pit be 18" or larger in diameter.
4. Vent hole. It is necessary that all submersible sump, effluent, and sewage
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 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. 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.
5. Pump should be checked frequently for debris and/or buildup which may
interfere with the float "on" or "off" position. Repair and service should be
performed by Zoeller Pump Company Authorized Service and Warranty Center.
6. Maximum operating temperature for standard model pumps must not exceed
130 °F.
7. 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.
8. For health reasons, do not unplug, turn off, or disable pump and use pump tank
system as a way to fill up a sink or laundry tray, etc.
9. Pumps must be installed in accordance with the National Electrical Code
and all applicable local codes and ordinances. Pumps are not to be installed
in locations classified as hazardous in accordance with National Electric Code,
ANSI, NFPA 70.
NOTE: Pumps with the "UL" mark and pumps with the "US" mark are tested to UL
standard UL778. CSA certified pumps are certified to CSA standard C22.2 No. 108.
