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 low during pump

servicing.

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.

between the pump and the control

panel must be made in accordance

with

the

electric

codes.

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.

Always

rely

upon

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

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.

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

PUMP TO 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.

Wire Size:

If longer power cable is required

consult a quali ed electrician for

proper wire size.

Pre-Operation

1. Check Voltage and Phase -

Certi ed

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.

Incorrect rotation for Single-Phase

pumps is unlikely. If the rotation is

incorrect contact factory.

4. Insulation Test - An insulation

(megger)

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

checks when pump is removed from

operation

when

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

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 from housing. With a

ashlight, visually inspect the oil in

the housing 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, from

housing.

Check oil for contamination using



an oil tester with a range to 30

kilovolts breakdown.
