Applications

Preinstallation Checklist

Inspect your progressing cavity 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.

Carefully read all literature

to familiarize yourself with details re gard ing

in stal la tion and use. Retain materials for future reference.

Make sure pump connection con tains a ground ter mi nal.

The power

cord on all Zoeller Progressing Cavity Grind er Pumps con tains a green
con duc tor for grounding to help protect you against the pos si bil i ty of
electric shock.

Make certain the electrical service is within reach of the power
supply cord

Make sure any panels and branch circuits are equipped

with

proper size fuses and circuit break ers. An in de pen dent pow er circuit is
rec om mend ed, sized ac cord ing to the National Elec tri cal Code, for the
current shown on the grinder pump name plate.

For your protection, always dis con nect the pow er source to the

grinder pump before han dling.

All grinder pumps must be prop er ly

ground ed and wired in ac cor dance with the “Na tion al Elec tri cal Codes”
and all local codes and ordinances.

5. Installation of electrical hardware and checking of control pan

els

and circuits should be performed by a qualifi ed li censed electrician.

6. Risk of electrical shock - These pumps have not been in ves ti gat ed for

use in swimming pool areas.

7. According to the state of California (Prop 65), this product contains

chemicals known to the state of California to cause can cer and birth
defects or other reproductive harm.

Make sure the power source is capable of handling the

electrical re quire ments of the grinder pump, as indicated on the
nameplate.

A dis con nect switch should be installed ahead of the pump.

3. The progressing cavity grinder pumps are operated by variable level

fl oat control switches. It is the re spon si bil i ty of the in stall ing party to
see that fl oat 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 rec om mend ed to use rigid pipe and fi ttings and the pit be
at least 24" in diameter for simplex sys tems and 36" in di am e ter 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 lev el
fl oat control switches. Repair and service, other than cutter as sem bly
main te nance, should be per formed by Zoeller En gi neered Products
au tho rized service stations only.

5. Maximum operating tem

per a ture must not ex

ceed 130°F,

(54°C).

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.

To ensure proper pump operation, a swing or fl apper 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 star cutter lo cat ed on

bottom of the unit with fi ngers.

Use a wrench when check ing

or re mov ing star cutter.
