ALL RETURNED

PRODUCTS MUST BE

CLEANED, SANITIZED,

OR RECONTAMINATED

PRIOR TO SHIPMENT, TO

INSURE EMPLOYEES WILL NOT BE EXPOSED

TO HEALTH HAZARDS IN HANDLING SAID

MATERIAL. ALL APPLICABLE LAWS AND

REGULATIONS SHALL APPLY.

Installation, wiring,
and junction
connections must be in accordance with
the National Electric Code and all applicable
state and local codes. Requirements may
vary depending on usage and location.

Installation and
servicing is to be
conducted by quali ed personnel only.

Keep clear of suction

and discharge
openings. Do not insert  ngers in
pump with power connected.

Always wear eye
protection when
working on pumps. Do not wear loose
clothing that may become entangled in
moving parts

Pumps build up heat
and pressure during

operation. Allow time
for pumps to cool
before handling or

servicing.

This pump is not
intended for use

in swimming pools or water
installations where human
contact with pumped  uid.

Risk of electric shock.

To reduce risk of
electric shock, always disconnect
pump from power source before
handling. Lock out power & tag.

Do not us these
pumps in water
over 104˚F. Do not exceed manufactures
recommended maximum performance, as
this could cause the motor to overheat.

Do not lift, carry or

hang pump by the
electrical cables. Damage to the
electrical cables can cause shock,

burnes or death. Never handle
connected power cords with wet hands. Use
appropriate lifting device.

Sump and sewage
pumps often handle
materials which could cause illness or disease.
wear adequate protective clothing when
working on a used pump or piping. Never
enter a basin after it has been used.

Failure to permanently
ground the pump,

motor and controls before
connecting to power can cause
shock, burns or death.

These pumps are NOT

to be installed in
locations classi ed as hazardous in
accordance with the National
Electric Code, ANSI/NFPA 70.

Receiving & Installation

Receiving Inspection

Upon receiving the pump, it should be
inspected for damage or shortages.
If damage has occurred, le a claim
immediately with the company that
delivered the pump. If the manual is
removed from the packaging, do not
lose or misplace.

Storage

Any product that is stored for a period
longer than six (6) months from the
date of purchase should be bench
tested prior to installation. A bench
test consists of, checking the impeller
to assure it is free turning and a run
test to assure the motor (and switch
if provided) operate properly. Do not
pump out of liquid.

Controls

Manual models require a separate
approved pump control device or panel
for automatic operation. Be sure the
electrical speci cation of the control
selected properly match the electrical
speci cations of the pump.

Figure 1

Submergence

The pump should always be operated in
the submerged condition. The minimum
sump liquid level should never be less than
above the pump’s volute (See Figure 1).

Installation

These pumps are recommended for
use in a sump, basin or lift station.

The sump, basin or lift station shall be
sealed and vented in accordance with
local plumbing codes. This pump is

designed to pump sewage, e uent
or wastewater, nonexplosive and
noncorrosive liquids and shall NOT
be installed in locations classi ed as
hazardous in accordance with the
National Electrical Code (NEC) ANSI/
NFPA 70 or Canadian Electric Code
(CEC). The pump should never be

installed in a trench, ditch, or hole with
a dirt bottom. The legs will sink into
the dirt and the suction will become
plugged.

The installation should be at a su cient
depth to ensure that all plumbing is
below the frost line. If this is not feasible,
remove the check valve and size the
basin to accommodate the additional
back ow volume.

Pumps are most commonly installed
in simplex, duplex or triplex stations or
basins with a slide rail system, which
allows the pump(s) to be installed or
removed without requiring personnel to
enter the station, or resting on the basin
 oor.

Discharge Piping

Discharge piping should be as short as
possible and sized no smaller than the
pump discharge. Do not reduce the

discharge pipe size below that which
is provided on the pump.

Both a check valve and a shut-o valve
are recommended for each pump. The
check valve is used to prevent backow
into the sump. The shut-o valve is used
to manually stop system ow during
pump servicing.

Liquid Level Controls

The level control(s) should be mounted
on the discharge piping, a cable rack or
 oat pole. The level control should have
adequate clearance so it cannot hang
up in it’s swing and that the pump is
completely submerged when the level
control is in the “O ” mode. By adjusting
the cord tether the control level can be
changed. One cycle of operation should
be observed, so that any potential
problems can be corrected.

It is recommended that the level control
 oat should be set to insure that the
liquid in the sump never drops below the
top of the motor housing or a minimum
level of 10 inches above the basin  oor.

Electrical Connections

Power/control cables:

The power/control cables mounted to
the pump must not be modied in any
way except for shortening to a specic
application. Any splice between the
pump and the control panel must be
made in accordance with the electric
codes. It is recommended that a junction
box, if used, be mounted outside the
sump or be of at a minimum Nema
4 construction if located within the
wet well. DO NOT USE THE POWER/

CONTROL CABLES TO LIFT PUMP.

Always rely upon a Certi ed Electrician
for installation.

Overload Protection:
Single Phase - The stator in-winding

overload protector used is referred to
as an inherent overheating protector
and operates on the combined e ect
of temperature and current. This means
that the overload protector will trip out
and shut the pump o if the windings
become too hot, or the load current
passing through them becomes too high.
