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.
3. Zoeller does not recommend using grinder pumps in any part of a septic system.
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
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 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.
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.
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.
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 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.
11. Risk of electric shock. These pumps have not been investigated for use in marine
areas.
12.
Do not attempt to turn cutter located on bottom of the unit with fingers.
Use allen wrench when checking or removing cutter.

CAUTION
1. 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
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" (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 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 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.
