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.

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 or duplex 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.

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 cable:

The power cable 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 CABLE TO LIFT PUMP.

Bottom of Feet

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.

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.

Installation & Service

IMPORTANT ! - The overload will then

automatically reset and start the pump
up after the motor cools to a safe
temperature. In the event of an overload,
the source of this condition should be
determined and corrected immediately.

WARNING! - DO NOT LET
THE PUMP CYCLE OR RUN IF
AN OVERLOAD CONDITION
OCCURS !

If current through the temperature sensor
exceeds the values listed, an intermediate
control circuit relay must be used to
reduce the current or the sensor will not
work properly.

Pre-Operation

1. Check Voltage and Phase - Compare
the voltage and phase information
stamped on the pump name plate.

2. Check Pump Rotation - Improper
motor rotation can result in poor
pump performance and can damage
the motor and/or pump. Check
rotation on three phase units by
momentarily applying power and
observe the “kickback”.

Kickback should always be in a
counter-clockwise direction as
viewed from motor end or opposite
to impeller rotation. Impeller rotation
is counter-clockwise as viewed from
bottom of pump.

3. Name Plate - Record the information
from the pump name plate to
drawing in front of manual for future
reference.

4. Insulation Test - An insulation
(megger) test should be performed
on the motor. Before the pump is put
into service. The resistance values
(ohms) as well as the voltage (volts)
and current (amps) should be
recorded.

5. Pump-Down Test - Be sure pump
has been properly wired, lowered into
the basin, sump or lift station, check
the system by lling with liquid and
allowing the pump to operate through
its pumping cycle. The time needed to
empty the system, or pump-down
time along with the volume of water,
should be recorded.

Maintenance

No lubrication or maintenance is required.
Perform the following checks when pump
is removed from operation or when pump
performance deteriorates:

a). Inspect motor chamber for oil level
and contamination.
b). Inspect impeller and body for
excessive build-up or clogging.
c). Inspect motor, bearings and shaft seal
for wear or leakage.

Servicing

NOTE: Item numbers in ( ) refer to Figures
6 through 10.

Cooling Oil - Anytime the pump is
removed from operation, the cooling oil
in the motor housing should be checked
visually for oil level and contamination.
To check oil, set unit upright. Remove
pipe plug (20) from housing (4). With a
ashlight, visually inspect the oil in the
housing (4) to make sure it is clean and
clear, light amber in color and free from
suspended particles. Milky white oil
indicates the presence of water. Oil level
should be just above the motor when
pump is in vertical position.

Oil Testing

• Drain oil into a clean, dry container by
placing pump on it’s side, remove pipe
plug (20), from housing (4).

• Check oil for contamination using an
oil tester with a range to 30 Kilovolts
breakdown.

• If oil is found to be clean and
uncontaminated (measuring above
15 KV. breakdown), rell the housing.

• If oil is found to be dirty or
contaminated (or measures below
15 KV. breakdown), the pump must
be carefully inspected for leaks at the
shaft seal, cable assembly, square ring
and pipe plug, before relling with oil. To
locate the leak, perform a pressure test.

After leak is repaired, dispose of old oil
properly, and rell with new oil.
