1.2 Machine Description and Intended Use

This machine is a submersible cutter pump. The Wacker Neuson

Submersible Cutter Pump consists of an electric motor, an impeller with a

carbide tip and cutter plate, a stand, and a metal casing with ports for

water or sewage suction and discharge. During operation, the impeller

cuts solid material until it is small enough to pass through the discharge

port. Power is supplied to the pump through a corded plug or a hard-wired

connection, depending on the installation. The operator connects pipes to

the pump and routes them so that water or sewage is pumped from the

work area and discharged into an appropriate location.

This machine is intended to be used for residential, commercial, and

industrial pumping of waste water with variable solids inclusion. This

machine is designed and intended to operate efficiently up to the flow,

head, and suction lift limits stated within the product specifications.

This machine has been designed and built strictly for the intended use

described above. Using the machine for any other purpose could

permanently damage the machine or seriously injure the operator or other

persons in the area. Machine damage caused by misuse is not covered

under warranty.

The following are some examples of misuse:

• Pumping flammable, explosive, or corrosive fluids

• Pumping hot or volatile fluids that result in pump cavitation

• Operating the pump outside of product specifications due to incorrect

diameter pipes, incorrect length pipes, other inlet or outlet

restrictions, or excessive suction lift or head

• Using the machine as a ladder, support, or work surface

• Using the machine to carry or transport passengers or equipment

• Operating the machine outside of factory specifications

• Operating the machine in a manner inconsistent with all warnings

found on the machine and in the Operator’s Manual.

This machine has been designed and built in accordance with the latest

global safety standards. It has been carefully engineered to eliminate

hazards as far as practicable and to increase operator safety through

protective guards and labeling. However, some risks may remain even

after protective measures have been taken. They are called residual

risks. On this machine, they may include exposure to:

• Electric shock from improper electrical connections or high voltage

• Personal injury from improper lifting techniques

• Projectile hazard from discharge

PSC EX Safety Information

wc_si000372gb.fm 11

To protect yourself and others, make sure you thoroughly read and

understand the safety information presented in this manual before

operating the machine.

Operator qualifications

Only trained personnel are permitted to start, operate, and shut down

the machine. They also must meet the following qualifications:

• have received instruction on how to properly use the machine

• are familiar with required safety devices

The machine must not be accessed or operated by:

•children

• people impaired by alcohol or drugs

Personal Protective Equipment (PPE)

Wear the following Personal Protective Equipment (PPE) while

operating this machine:

• Close-fitting work clothes that do not hinder movement

• Safety glasses with side shields

• Hearing protection

• Safety-toed footwear

Safety Information PSC EX

12 wc_si000372gb.fm

1.3 Operating and Electrical Safety

To reduce risk of electric shock, connect only to a properly grounded,

grounding-type receptacle.

Risk of electric shock—this pump has not been investigated for use in

swimming pool areas.

An acceptable motor-control switch shall be provided at the time of

installation according to local codes and regulations.

To reduce risk of electric shock, follow instructions in this manual for

proper installation.

CAUTION: This pump may automatically restart. Prior to working on

the pump or control panel, all supply circuits must be disconnected.

CAUTION: Risk of shock—do not remove cord and strain relief.

1.4 Informational Labels

Label Meaning

A nameplate listing the model number, item num-

ber, revision number, and serial number is

attached to each unit. Please record the informa-

tion found on this nameplate so it will be available

should the nameplate become lost or damaged.

When ordering parts or requesting service infor-

mation, you will always be asked to specify the

model number, item number, revision number,

and serial number of the unit.

CAUTION

Do not attempt to operate this product before reading the

Operator’s Manual and understanding its contents.

Mishandling of this product may result in explosion, fire, or

electrical shock.

 Do not pull on the power cord or use the power cord to lift

the pump.

 Always use a dedicated ground leakage circuit breaker.

 Be sure to install the ground wire securely.

 Be sure to disconnect the power supply before handling

or inspecting the pump.

Never insert your hand into the pump inlet holes while the

pump is connected to the power supply.

2.2 Prior to Operation

When the pump is delivered, first perform the following checks:

• Inspection

While unpacking, inspect the product for damage during shipment, and

make sure all bolts and nuts are tightened properly.

• Specification check

Check the model number to make sure it is the product that was

ordered. Be certain it is the correct voltage and frequency.

Note: If there is any problem with the product as shipped, contact your

nearest dealer or Wacker Neuson representative at once.

• Product specifications

Do not operate this product under any conditions other than those for

which it is specified. Failure to observe this precaution can lead to

electrical shock, current leakage, fire, water leakage or other

problems.

2.3 Installation

Preparing for Installation

Observe the following points when preparing to install the pump.

• Be aware that leakage of pump lubricants may cause pollution of

water.

• An appropriate plug or electrical connection must be provided

according to local codes and standards. Refer to the wiring

diagram.

• Use with a power supply voltage within ±5% of the rated voltage.

Operating Safety

• Do not operate the pump if the maximum water pressure in the

area exceeds 0.3 Mpa–discharge pressure.

• Do not use this pump in liquids other than water, such as oil, salt

water, or organic solvents. Contact your Wacker Neuson dealer

with questions about specific fluids.

• Do not use in water temperatures outside the range of 0–40°C

(32–104°F) which can lead to failure, electrical leakage or shock.

• Do not use in the vicinity of explosive or flammable materials.

• Do not operate the pump if any parts are loose or missing.

CAUTION

PSC EX Operation

wc_tx001311gb.fm 17

2.4 Preparing for installation

Before installing the pump at a work site, you will need to have the

following tools and instruments ready:

• Insulation resistance tester (megohmmeter)

• AC voltmeter

• AC ammeter (clamp-on type)

• Bolt and nut tighteners

• Power supply connection tools (screwdriver or box wrench)

Note: Please also read the instructions that come with each of the test

instruments.

Measure resistance

Use a megohmmeter to measure the insulation resistance between

each core lead and the ground lead to verify the insulation resistance

of the motor.

• Reference insulation resistance: 20MΩ or greater

Note: The reference insulation resistance (20M

Ω

or greater) is the value

when the pump is new or has been repaired. For the reference value after

installation, see “Periodic Maintenance Table.”

2.5 Installing the Pump

Overview

This pump requires careful installation to operate at peak efficiency.

Observe the following recommendations when installing the pump.

Placing the pump

A sample installation diagram is provided below. Contact your Wacker

Neuson dealer for help in installing the pump for your particular

application.

• Install the pump on a flat, smooth surface, such as a concrete

pad.

• Do not place the pump in areas that may be susceptible to

turbulence or may allow the pump to take in air—for example,

near the inlet of a water tank. Install a baffle if it is impossible to

keep the pump away from these areas.

• Install piping so that air pockets cannot form anywhere in the

system.

NOTICE: If the pump is being controlled automatically, discharged water

could flow backwards. This backflow may trigger the water surface control

immediately, forcing the pump to continuously cycle ON and OFF.

Permanent damage to the pump may result.

• Install a check valve if the pump tank is deep, or if the vertical

head or the lateral distance is long.
