 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.

 11.  Prop65 Warning for California residents: 
 

: Cancer and  Reproductive Harm- 

        www.P65Warning.ca.gov.

  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.
