and pumping sanitary sewage from submersible lift stations. The
pump is intended to grind and pump reasonable quantities of items
normally found in sanitary sewage applications.
2. Zoeller 7020 and 7021 Progressing Cavity Grinder Pumps can be
installed in new applications or as a replacement for another
grinder pump of like size and capacity.
3. The 7020 and 7021 can be installed in a Prepackaged Job Ready
System or may be used in a Field Assembled basin package. Page

APPLICATIONS
PREINSTALLATION CHECKLIST
1.
Inspect your progressing cavity grinder pump
. If the unit has been damaged
in shipment, contact your dealer before installing.
Do Not
remove the
test plugs in the cover or the motor housing.
2.
Carefully read all literature
to familiarize yourself with details regarding
installation and use. Retain materials for future reference.
1.
Make sure pump connection contains a ground terminal.
The power cord
on all Zoeller Progressing Cavity Grinder Pumps contains a green
conductor for grounding to help protect you against the possibility of
electric shock.
2
.
Make certain the electrical service is within reach of the power supply cord.
3.
Make sure any panels and branch circuits are equipped
with proper size fuses
and circuit breakers. An independent power circuit is recommended,
sized according to the National Electrical Code, for the current shown
on the grinder pump nameplate.
4.
For your protection, always disconnect the power source to the grinder
pump before handling.
All grinder pumps must be properly grounded
and wired in accordance with the “National Electrical Codes” and all
local codes and ordinances.
5. Installation of electrical hardware and checking of control panels
and circuits should be performed by a qualified licensed electrician.
6. Risk of electrical shock - These pumps have not been investigated for
use in swimming pool areas.
7.
Prop65 Warning for California residents:
: Cancer and Reproductive Harm-
www.P65Warning.ca.gov.
1.
Make sure the power source is capable of handling the electrical
requirements of the grinder pump, as indicated on the nameplate.
2.
A disconnect switch should be installed in the circuit bringing electrical
power to the pump.
3. The progressing cavity grinder pumps are operated by variable level
float control switches. It is the responsibility of the installing party to
see that float control switches will not hang up on the grinder pump
or other pit peculiarities and are secured so that the grinder pump
will shut off. It is recommended to use rigid pipe and fittings and the
pit be at least 24" in diameter for simplex systems and 36" or larger in
diameter for duplex systems.
4. Grinder installations should be checked yearly for debris and/or build
up which may interfere with the “ON” or “OFF” positions of variable
level float control switches. Repair and service, other than cutter
assembly maintenance, should be performed by a Zoeller Authorized
Service & Warranty Center or Customer Care Center.
5. Maximum operating temperature must not exceed 130 °F (54 °C).
6.
Do not operate an unsubmerged progressing cavity pump
. Dry pump
operation may damage the hydraulic stator due to lack of lubrication.
Do not run dry.
7.
To ensure proper pump operation, a swing or flapper style check valve
must be installed in the pump discharge line. A faulty or non-functional
check valve when combined with a pressure sewer may prevent the pump
from starting.
Do not attempt to turn the cutter blades
located on bottom of the unit with fingers.
Use a wrench
when checking or removing the cutter.
CAUTION
SEE BELOW FOR
LIST OF CAUTIONS
SEE BELOW FOR
LIST OF WARNINGS
Progressing cavity grinder pumps are designed for
pressure sewer applications. A UL listed and CSA certified pressure relief
valve must be installed in the system to prevent excessive pressure buildup.
In instances where property damages are incurred as a result of an alleged product failure, the property
owner must retain possession of the product for investigation purpose.
