Notice to installing contractor:  Instructions must remain with installation.







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.


Carefully read the literature provided to familiarize yourself with specific details regarding installation and use. These materials should be retained for future reference.

3.   Zoeller does not recommend using grinder pumps in any part of a septic system.







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 

governing electrical codes for the current shown on the pump name plate.


Testing for ground.

   As a safety measure, each electrical outlet 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 to your outlet.  If they 

are not, call a qualified licensed electrician.


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.  

  6.  Installation and servicing of the pump's electrical circuits and hardware should only be 

performed by a qualified, licensed electrician.

  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.


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 contains 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.


Risk of electric shock.

  These pumps have not been investigated for use in marine 



Do not attempt to turn cutter located on bottom of the unit with fingers.


Use allen wrench when checking or removing cutter.



   Zoeller Grinder Pumps are designed for grinding and pumping sewage from homes. The 

pump is intended to grind and pump all normal sewage including reasonable quantities 

of disposable diapers, sanitary napkins, paper towels, rubber materials, cleaning wipes, 

plastics, cigarette butts and other items normally found in sewage. 

  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” (45 cm) or larger in 



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” (5 mm) 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 visible when pump is operating.

  5.  Pump should be checked frequently for debris and/or build up which may interfere with 

the float “on” or “off” position. Repair and service should be performed by an Authorized 

Zoeller Service Station only.

  6.  Maximum operating temperature for standard model pumps must not exceed 130 °F 

(54 °C). 

  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.
