SAFETY INFORMATION

SAFETY SYMBOLS

This is the safety alert symbol. When you see this symbol on your

pump or in this manual, look for one of the following signal words and

be alert to the potential for personal injury:

warns about hazards that will cause serious personal

injury, death or major property damage if ignored.

warns about hazards that can cause serious personal

but not related to hazards.

California Proposition 65 Warning

This product and related accessories contain

chemicals known to the State of California to cause cancer, birth

defects or other reproductive harm.

GENERAL SAFETY

 Do not touch an operating motor. Modern

motors can operate at high temperatures. To avoid burns

when servicing pump, allow it to cool for 30 minutes after

shutdown before handling.

 Follow all applicable local and state codes and regulations.

 Submersible pumps are not approved for and should not be

used in swimming pools, recreational water installations,

decorative fountains or any installation where human

contact with the pump fluid is common. Pump is designed

for municipal and commercial wastewater applications.

 Keep safety labels in good condition, replacing any missing

or damaged labels.

 DO NOT run the pump dry. Dry running can overheat the

pump, (causing burns to anyone handling it) and will void the

warranty.

 The pump is permanently lubricated. No oiling or greasing

is required in normal operation.

 Periodically inspect pump and system components.

 Wear safety glasses at all times when working on pumps.

 Keep work area clean, uncluttered and properly lighted.

Store all unused tools and equipment.

 DO NOT use to pump flammable liquids.

 RISK OF FIRE OR EXPLOSION. Can cause

severe personal injury, property damage or death. Do not

smoke or use open flames in or around this system.

 CUTTING RISK. Risk of serious cutting or

amputation exists. Use caution as liner plate is extremely

sharp. Always keep fingers and hands away from cutting

profiles. Disconnect all power sources prior to servicing

pump. Pump may start without warning.

 RISK OF ASPHYXIATION. Installer(s) and/or

service personnel must use proper Personal Protective

Equipment and follow OSHA 29 CFR 1910.146 or OSHA 29

CFR 1926. Pump may be installed in a location classified as

a confined space.

 BIOHAZARD RISK. Once wastewater source

has been connected to system, Biohazard Risk exists.

Installer(s) and/or service personnel must use proper

personal Protective Equipment and follow handling

procedures per OSHA 29 CFR 1910.1030 when handling

equipment after wastewater source has been connected to

system.

 NOTICE: FM rated models are only to be used in 60hz

applications.

When installing, operating, or servicing this pump, follow the safety

instructions listed below.

 ELECTROCUTION HAZARD: Must be installed

by a qualified professional. Disconnect all electrical power

before attempting service.

 DO NOT modify the cord. When wiring to a system control,

connect ground lead to the system ground.

 DO NOT splice the electrical power cord.

 DO NOT allow the power leads on the end of the electrical

cords to be submerged.

 DO NOT handle or service the pump while it is connected

tothe power supply.

A water test must be taken before installation

of any water treatment equipment. The water quality can

significantly influence the life of your system. You should

test for corrosive elements, acidity, total solids and other

relevant contaminants, including chlorine and treat your water

appropriately to ensure satisfactory performance and prevent

premature failure.

g. Is current balanced across all 3 legs – or is no current flow

present on 1 or more legs?

i. Yes – No Problem

ii. No – Motor windings likely open or grounded, go to step 5

5. Motor resistance to ground test –. Use Meg ohm meter – set

on 500 volts

a. Disconnect station power, turn off breaker(s), lock-out/tag-

out, make safe.

b. Mark and remove motor leads T1, T2, T3, Heat Sensor and

Seal Leak probe(s)

: IF T1, T2, T3 are not re-installed in the same

locations, rotation will be reversed, potentially resulting in

damage to pump and/or other system components.

c. Connect ground lead of meter to a good ground in panel

d. Test each motor lead separately against ground, test the

individual seal probe(s) against ground, test individual heat

sensors against ground. Do NOT TEST ACROSS HEAT SENSOR

LEADS. HEAT SENSOR CAN BE DESTROYED.

e. Is resistance to ground greater than local code or Ieee-43

Standard (1 megohm + 1 meg per 1000 motor volts, i.e. for a 460

volt motor 1 meg + 460/1000 = 1.46 Meg-Ohms

i. Was resistance to ground greater than minimum

specification?
