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.
