Preinstallation Checklist
1.
Inspect your grinder pump.
If the unit has been damaged in shipment, contact
your dealer before installing.
Do Not
remove the test plug in the cover nor 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 Grinder Pumps contains a green conductor for grounding to help
protect you against the possibility of electric shock.
2.
Make certain the receptacle 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.
Automatic pumps have three prong plug caps and must be connected to a
three prong grounded receptacle with ground fault circuit interrupter (GFCI).
5.
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.
6. Installation of electrical hardware and checking of control panels and circuits
should be performed by a qualified licensed electrician.
7. Risk of electrical shock - These pumps have not been investigated for use in
swimming pool areas.
8.
Prop65 Warning for California residents:

SEE BELOW FOR LIST OF WARNINGS
CAUTION
SEE BELOW FOR LIST OF CAUTIONS
Do not attempt to turn cutter located on bottom
of the unit with fingers.
Use a wrench when checking or remov-
ing cutter.
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 ahead of the pump.
3. If Grinder pumps are operated by control panels with variable level float
control switches, it is the responsibility of the installing party 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 24" in diameter for simplex systems and
36" in diameter for duplex systems or larger.
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 Zoeller Engineered Products authorized service stations only.
5. Maximum operating temperature must not exceed 130 °F, (54 °C).
6.
Pump and float switch electrical connections must be permanently installed,
operational and protected from submergence.
7.
Junction box conduit must be installed with watertight connection. Zoeller
junction boxes include a UL Listed potting kit for sealing conduit. Failure to
properly install this sealant material could void warranty.
