NOTICE: INDICATES SPECIAL INSTRUCTIONS

WHICH ARE VERY IMPORTANT AND

MUST BE FOLLOWED.

THOROUGHLY REVIEW ALL INSTRUCTIONS AND

WARNINGS PRIOR TO PERFORMING ANY WORK

ON THIS PUMP.
MAINTAIN ALL SAFETY DECALS.

All electrical work must be performed by

a qualified technician. Always follow the

National Electrical Code (NEC), or the Canadian Electri-

cal Code, as well as all local, state and provincial codes.

Code questions should be directed to your local electrical

inspector. Failure to follow electrical codes and OSHA

safety standards may result in personal injury or equip-

ment damage. Failure to follow manufacturer’s installation

instructions may result in electrical shock, fire hazard,

personal injury or death, damaged equipment, provide

unsatisfactory performance and may void manufacturer’s

warranty.

Pumps are listed for use in water and sew-

age as Class 1, Groups C and D hazardous

locations. As defined by the NEC hand book, a Class 1

location is one in which flammable gases or vapors are or

may be present in quantities sufficient to produce explosive

or ignitable mixtures. See the NEC handbook for Groups C

and D definitions.

See specific pump and motor nameplates

for all agency Listings.
See motor nameplate for all electrical

ratings.
The user must provide an appropriate

motor starter (control panel) with ther-

mal (high temperature) protection, over

current protection and moisture detection circuits. The

over current protection must provide Class 10 quick trip

protection. Consult Motor Installation Manual as well

as the National Electric Code, Canadian Electric Code,

state, provincial and/or other local codes which may

apply.

DANGER

WARNING

CAUTION

This motor is rated for continuous duty

when fully submerged in liquid and

15-minute duty in air when operated at nameplate HP.

Do not exceed 15 minutes in air duty rating. Consult

motor manual for further information.

PRE-INSTALLATION CHECKS

Open all cartons and inspect for shipping damage. Report

any damage to your supplier or shipping carrier immedi-

ately.
Verify that all equipment is the correct voltage and phase.

Warranty does not cover damage caused by connecting

pumps and controls to an incorrect power source (volt-

age/phase supply).
Record the model numbers and serial numbers from the

pumps and control panel on the front of this instruction

manual for future reference. Give it to the owner or affix

it to the control panel when finished with the installation.

LIFTING OF PUMP

DO NOT LIFT, CARRY OR HANG

PUMP BY THE ELECTRICAL

CABLES. DAMAGE TO THE

ELECTRICAL CABLES CAN CAUSE

SHOCK, BURNS OR DEATH.

Lift the pump with an adequately sized chain or cable at-

tached to the lifting lugs on the motor. DO NOT damage

electrical and sensor cables while raising and lowering unit.

GUIDE RAIL SYSTEM

Hazardous Class 1 environments require

non-sparking guide rail or disconnect equip-

ment. Mating parts constructed of brass or stainless steel will

prevent sparks during equipment installation and removal.

We offer the A10-30B, A10-40B and A10-60B cast iron and

brass guide rail assemblies for use in these locations.
Typical wastewater collection systems are possibly

dangerous environments due to gases collected in the

wet well. Most codes do not allow personnel to enter a

wetwell without the correct protective equipment and

training. Guide rail systems are designed to allow easy

removal of the pump without the need for entry into the

wetwell or need to disturb piping.
An optional guide rail system facilitates pump installation

and removal for inspection and maintenance. Guide rails

eliminate this safety concern. They save time as there is

no need to disturb piping to pull a pump for service.
NOTICE: FOLLOW THE INSTALLATION

INSTRUCTIONS THAT ARE SUPPLIED

WITH THE GUIDE RAIL SYSTEM.

Installation of the guide rail should locate the pump

opposite the influent opening preventing stagnate areas

where solids can settle.
The pit floor must be flat under the guide rail base and

have sufficient loading capacity to support the entire

weight of the guide rail, discharge piping and the pump.

See Typical Installations Drawings.
