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 ALLOW THE

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.

Pre-Operation

Check Voltage and Phase -

Compare the voltage and phase

information stamped on the

pump name plate.

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

viewed from motor end or opposite

to impeller rotation. Impeller rotation

is counter-clockwise as viewed from

bottom of pump.

into the basin, sump or lift station,

check the system by filling 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.

Installation & Service

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

Figure 5.

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 (34) from

housing (3). With a flashlight, visually

inspect the oil in the housing (3) 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 (34), from

housing (3).

Check oil for contamination using

an oil tester with a range to 30

kilovolts breakdown.

If oil is found to be clean and

uncontaminated

above 15 kV breakdown), refill 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 refilling with oil. To

locate

the

leak,

pressure test.

After leak is repaired, dispose of old

oil properly, and refill with new oil.
