INTRODUCTION

Pump Works submersible sump pumps are recommended for use in basins or lift stations and are
suitable for pumping clear water . Do not use the pumps in applications where effluent (grey water),
sewage or any other debris (gravel, sand, floating debris, etc . ) is present .
This owner's manual provides you with the information required to safely own and operate your
Pump Works submersible sump pump . Retain these instructions for future reference . The submersible
sump pump you have purchased is of the highest quality workmanship and material, and has been
engineered to provide long and reliable service . This product has been carefully tested, inspected, and
packaged to ensure safe delivery and operation . Please examine your product carefully to ensure that
no damage occurred during shipment . If damage has occurred, please contact the place of purchase .
They will assist you in replacement or repair, if required .

of the unit or remove housing screws .

INSTALLATION

The pump must be installed in a suitable gas-tight basin that is at least 14" in diameter and 18" deep .
Clean any debris from sump pit and set pump in center of pit . A solid bottom will prevent clogging of
the pump from sand and dirt .
The pump must be placed on a hard level surface . Never place the pump directly on clay, earth, or
gravel surfaces . These surfaces contain small stones, gravel, sand etc . that may clog or damage the
pump and cause pump failure .
Connect discharge piping . Use pipe joint compound at all connections . Sump pumps can be piped to
discharge into the house drainage system, to a dry well, splash block, or to a storm drain depending on
local plumbing codes . The discharge pipe should be as short as possible and contain as few elbows as
necessary . The discharge pipe should be the same diameter as the discharge size to reduce pipe friction
losses . Smaller pipe will restrict capacity and reduce pump performance . The sump pump comes with
a 1-1/2" female pipe thread discharge .
Support pump and piping while assembling and when installed . Failure to do so may cause piping to
break, pump failure, motor bearing failures, etc .
Always install a union in the discharge line just above the sump pit to allow for easy removal of the
pump for cleaning or repair .
A check valve must be used in the discharge line to prevent back flow of liquid into the basin .
When a check valve is used, drill a relief hole (3/16" diameter) in the discharge pipe . This hole should be
located below the floor line between the pump discharge and the check valve . Unless such a relief hole
is provided, the pump could "air lock" and will not pump water even though it will run .
Be sure that the float has adequate clearance and cannot become stuck on the sides of the sump . Do
not allow the cord to interfere with the free movement of the float or to drape over the motor housing .
The cord should be taped to the pump discharge piping with electrical tape .
D A N G E R
Test operation of the sump system following the instructions outlined in the Sump System Operation
Testing section of this manual . Do not attempt to operate the pump without water; this will damage
the seals and bearings and could result in permanent damage to the pump .
Place cover over sump . The cover will help prevent solid debris from filling the pit and will guard
against accidental injury .
WARNING: Always disconnect the electrical power before touching the pump or discharge when
water is present in the sump . Failure to do so can result in hazardous electrical shock .

ELECTRICAL CONNECTIONS

Check local electrical and building codes before installation . The installation must be in accordance with
their regulations as well as the most recent National Electrical Code (NEC) .
To conform to the National Electrical Code, all pumps must be wired with 14 AWG or larger wire . For
runs up to 250', 14 AWG wire is sufficient . For longer runs, consult a qualified electrician or the factory .
Check the pump label for proper voltage required . Do not connect to voltage other than that shown .
A ground fault circuit interrupter (GFCI) is required .
The pump should be connected or wired to its own circuit with no other outlets or equipment in the circuit
line . The fuses and circuit breaker should be of ample capacity in the electrical circuit . See table below .

SUMP SYSTEM OPERATION TESTING

TESTING PUMP OPERATION
1 . These pumps are equipped with a float switch . Be sure that the float has adequate clearance
and cannot become stuck on the sides of the sump .
2 . When the pumps are installed in a basin with a sealed cover, switch operation cannot be
observed . The sump cover will typically have a spare hole that is plugged with a rubber plug .
This plug can be removed to observe switch operation .
3 . Plug the power cord into a grounded receptacle with a voltage consistent with the pump
voltage as indicated on the pump nameplate .
4 . Be sure the gate valve in the discharge line is open .
5 . Run water into the sump basin until the primary pump is activated .
a . Do not attempt to run the pump without water; this could result in permanent damage
to the pump .
6 . Confirm that the primary pump and its control switch are functioning as intended .
7 . Confirm that ON-OFF levels are within specification and that no potential obstructions exist that
could inhibit switch operation .
8 . Confirm that there are no leaks in the primary pump discharge plumbing and main home drain
pipe plumbing .
a . It is normal for a stream of water to spray from the air bleed hole in the plumbing of
the primary pump . Confirm that this spray is captured within the sump basin .
9 . Allow the pump to operate through several on-off cycles .
If the pump does not operate properly, consult the troubleshooting chart in this manual . If trouble
cannot be located with the steps shown, consult your pump dealer or call 1-888-956-0000 .
Do not let the unit run dry (without liquid) . It is designed to be cooled by pumping fluid . Damage to
the seal and motor may occur if the pump is allowed to run dry .
If the unit is going to be idle for a period of time, follow the cleaning instructions outlined in the next
section . Do not let the unit freeze in the wintertime . This may cause cracking or distortion that may
destroy the unit .
