READ THESE INSTRUCTIONS CAREFULLY

Read these installation instructions in detail before installing
your pump. Be sure to check the following:

1. Be certain the motor is connected for the correct line
voltage being used (check motor nameplate).

2. Be certain the pump is completely primed before starting.
Otherwise damage may occur to the seal.

Every pump is tested before leaving the factory, and its
performance depends largely on the installation.

INSPECTION AND STORAGE

1. Immediately upon receipt of shipment, inspect and
check the shipping document and report to the
Transportation Company’s local agent any damage
or shortage. If the unit is received sometime before
it can be used, it should be inspected, re-crated and
stored in a dry location.

2. Unless otherwise specifically agreed, all capacity,
head and efficiency guarantees are based on factory
test when handling clear, cold, fresh water at a
temperature not over 85°F.

LOCATION
IMPORTANT: In installations where property damage

might result from an inoperative or leaking pump due
to power outages, discharge line blockage or any other
reason, a back-up system(s) and/or warning system(s)
should be used.

1. Locate pump as close to the fluid source as possible.

CAUTION: The unit should be placed where the motor
and electrical components are protected from the
weather and extremes of heat, humidity and below
freezing temperatures.

2. Mount unit in a dry location that is easily accessible
for inspection and maintenance. Allow ample
clearance around the unit for free air circulation.
If a dry location is not available mount it on a
foundation well above the wet floor.

SUCTION LIMITATIONS

1. Units are non self-priming. Normally after being
primed the total suction lift of the pump is 15 feet.

2. Where liquids at or near their boiling points are
being handled, the supply must be located above
the suction, so that the available NPSH will be
greater than that required by the unit.

PIPING

1. Do not use the pump as support to the piping. The
pipe must be independently supported near the
pump so that no strains will be transmitted to the
unit. Failure to do so will cause premature pump
failure and will void the warranty.

2. Suction and discharge sizes are selected for proper
performance of the pumping unit and are not
intended to determine the suction and discharge
pipe sizes. Pipe sizes must be determined by the
user based on the system requirements.

3. Install both a union and a gate valve (not furnished)
on the suction and discharge side of the pump for
service convenience.

CAUTION: Do not use a globe or other restricting
type of valve at the discharge. Globe valves seriously
restrict the capacity of the pump.

compound (male threads only) applied and drawn
up tightly.

CAUTION: The entire system must be air and water
tight for efficient operation.

SUCTION PIPING

1. Suction piping should be short in length, as direct
as possible, and never smaller in diameter than the
pump suction opening.

2. Use galvanized piping, rigid plastic or other suitable
pipe that will not collapse under suction.

3. The suction pipe should slope upward to the pump
inlet. A horizontal suction line must have a gradual
rise to the pump. Any high point in the pipe will
become filled with air and thus prevent proper
operation of the pump. When reducing the piping
to the suction opening diameter use an eccentric
reducer with the eccentric side down to avoid air
pockets. Never use a straight taper reducer in a
horizontal suction line, as it tends to form an air
pocket in the top of the reducer and the pipe.

Valves in Suction Piping

1. If the pump is operating under static suction lift
conditions, a foot valve may be installed in the
suction line to avoid the necessity of priming each
time the pump is started.

2

2. When foot valves are used, or where there are other

IL1001

possibilities of “liquid hammer”, close the discharge
valve before shutting down the pump.

3. The pump must never be throttled by the use of
a valve on the suction side of the pump. Valves
should be used only to isolate the pump for
maintenance purposes, and should always be
installed in positions to avoid air pockets.

DISCHARGE PIPING

On long horizontal runs it is desirable to maintain as
even a grade as possible. Avoid high spots, such as
loops, which will collect air and throttle the system or
lead to erratic pumping.

Valves In Discharge Piping

A check valve and gate valve should be installed in
the discharge. The check valve, placed between the
pump and the gate valve, protects the pump from
excessive pressure, and prevents liquid from running
back through the pump in case of power failure. The
gate valve is used in priming and starting, and when
shutting the pump down.

Pressure Gauges

Properly sized pressure gauges can be installed in
both the suction and discharge openings in the gauge
taps which are provided. The gauges will enable
the operator to easily observe the operation of the
pump, and also determine if the pump is operating in
conformance with the performance curve. If cavitation,
vapor binding or other unstable operation should
occur, widely fluctuating discharge pressure will be
noted.

ELECTRICAL CONNECTIONS
GROUNDING

1. To reduce the risk of electric shock. The motor must
be securely and adequately grounded to a grounded
metal raceway system or by using a separate
grounding wire connected to bare metal on the
motor frame, or to the grounding screw located
inside motor terminal box, or other suitable means.
Refer to National Electric Code (NEC Article 250
[Grounding]) for additional information.

2. All wiring should be preformed by a qualified
electrician and in accordance with the National
Electric Code, Local Electric Codes and the
Occupational Safety and Health Act (OSHA).

WARNING: Failure to connect the motor frame to
equipment grounding conductor by using green screw
may result in serious electrical shock.

WIRING CONNECTIONS

1. This unit is not water proof and is not intended to
be used in showers, saunas, or other potentially
wet locations. The motor is designed to be used
in a clean dry location with access to an adequate
supply of cooling air. Ambient temperature around
the motor should not exceed 104°F (40°C). For
outdoor installations motor must be protected by a
cover that does not block airflow to and around the

motor. This unit is not weatherproof nor is it able to
be submersed in water, or any other liquid.

2. Motor voltages will vary depending upon the motor
horsepower, phase and manufacturer. Refer to the
motor nameplate for voltage and electrical data.

WARNING: Make certain that the power supply
conforms to the electrical specifications of the motor
supplies. Failure to do so may cause premature motor
failure and will void the warranty.

3. For proper electrical connections, refer to the

connection diagram located on the nameplate
or inside the terminal box of the motor. Make
sure connections are correct for the voltage being
supplied to the motor.

4. Whenever possible, the pump should be powered
from a separate branch circuit of adequate capacity
to keep voltage drop to a minimum during starting
and running. For longer runs, increase wire size
in accordance with the Wire Selection Guide. (See
Figures 3 & 4)
