General Operation
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.
Checks to Make Before Installation
•
When a three-prong grounded plug is used:
•
Use the megohmmeter to measure the motor insulation resistance between the grounding prong and each one of the two
power prongs.
•
When connection wires are used:
•
With the megohmmeter, measure the insulation resistance
between the ground wire (Green) and each one of the two power
wires.
•
Reference insulation resistance: 20MΩ or greater
Note: The reference insulation resistance (20MΩ or greater) is the
value when the pump is new or has been repaired. For the reference
value after installation, see Maintenance and Inspection.
WARNING
CAUTION
4.3.1
wc_tx000111gb.fm
Precautions in Installation
When installing the pump, pay close attention to its center of gravity
and weight. If it is not lowered into place correctly, it may fall and be
damaged or cause injury.
When transporting the pump by hand, be sure to employ manpower
commensurate with the weight of the pump. To avoid back injury when
lifting the pump, bend the knees to pick it up rather than bending your
back only.
Do not under any circumstances install or move the pump by
suspending it from the cable assembly. The cable may be damaged,
causing current leakage, shock, or fire.
Avoid dropping the pump or other strong impact. Lift the pump by
holding it firmly with the hands or by attaching a rope or chain to the
lifting handle.
36
General Operation
CAUTION
4.3.2
Note: On cable assembly handling, see Electrical Wiring.
Avoid dry operation, which will not only lower performance but can
cause the pump to malfunction, leading to electrical leakage and
shock.
Install the pump in a location with sufficient water level, where water
collects readily.
Note: See Operation (“Operating Water Level”) for the water level
necessary for operation.
Note: The discharge end of the hose should be located higher than the
water surface. If the end of the hose is submerged, water may flow
back to the pump when the pump is stopped; and if the hose end is
lower than the water surface, water may overflow when the pump is
turned off.
If large quantities of earth are sucked up, damage resulting from

Performing electrical wiring
Electrical wiring should be performed by a qualified person in accord
with all applicable regulations. Failure to observe this precaution not
only risks breaking the law but is extremely dangerous.
Incorrect wiring can lead to electrical leakage, electrical shock or fire.
ALWAYS make sure the pump is equipped with the specified overload
protectors and fuses or breakers, so as to prevent electrical shock from
an electrical leak or pump malfunction.
Operate within the capacity of the power supply and wiring.
Grounding
DO NOT use the pump without first grounding it properly. Failure to
ground it can lead to electrical shock from a current leak or pump
malfunction.
DO NOT attach the grounding wire to a gas pipe, water pipe, lightening
arrestor or telephone grounding wire. Improper grounding can result in
electrical shock.
37
General Operation
WARNING
Connecting the power supply
Before connecting wires to the terminal, make certain the power supply
is turned off (circuit breaker, etc.), to avoid electrical shock, shorting,
or unexpected starting of the pump, leading to injury.
Before inserting the power supply plug, make certain the power supply
is turned off (circuit breaker, etc.), to avoid electrical shock, shorting,
or unexpected starting of the pump, leading to injury.
Do not use the pump with the cable assembly or plug connected
loosely, which can result in electric shock, shorting, or fire.
CAUTION
Draw power from a dedicated power outlet rated at 15 A or above.
Sharing the outlet with other equipment may cause overheating at the
branch outlet and could result in fire.
•
The three-prong grounded plug shall be connected as shown in
the drawing.
CAUTION: Be sure to use a dedicated power supply with a ground
leakage circuit breaker.
Note: The shape of the plug may differ from that shown in the
illustration.
See Graphic: wc_gr000242
CAUTION
wc_tx000111gb.fm
Cable Assembly
If it is necessary to extend the cable assembly, use a core size equal
to or larger than the original. This is necessary not only for avoiding a
performance drop, but to prevent cable overheating which can result in
fire, electrical leakage or electrical shock.
If a cable with cut insulation or other damage is submerged in the
water, there is a danger of damage to the pump, electrical leakage,
electrical shock, or fire.
Be careful not to let the cable assembly be cut or become twisted. This
may result in damage to the pump, electrical leakage, electrical shock,
or fire.
If it is necessary to submerge the connection wires of the cable
assembly in water, first seal the wires completely in a molded
protective sleeve, to prevent electrical leakage, electrical shock, or fire.
DO NOT allow the cable assembly wires or power supply plug to
become wet.
38
General Operation
Make sure the cable does not become excessively bent or twisted, and
does not rub against a structure in a way that might damage it.
If used in a deep-well installation the cable assembly should be
secured every twenty feet.
4.4
Operation
Before starting
4.4.1
Make sure once again that the product is of the correct voltage and
frequency rating.
CAUTION: Using the product at other than rated voltage and
frequency will not only lower its performance but may damage the
product.
Note: Confirm the rated voltage and frequency on the model
nameplate.
4.4.2
Confirm the wiring, supply voltage, circuit breaker capacity, and motor
insulation resistance.
Reference insulation resistance = 20 MΩ or greater.
Note: The reference insulation resistance (20 MΩ or greater) is the
value when the pump is new or has been repaired. For the reference
value after installation see Maintenance and Inspection.
4.4.3
The setting on the circuit breaker or other overload protector should be
made in accord with the rated current of the pump.
Note: See Standard Specifications for the rated current of the pump.
4.4.4
When powering the pump with a generator, do not share the generator
with other equipment.
Test Operation
NEVER operate the pump while it is suspended in the air. The recoil
may result in injury or other major accident.
WARNING
NEVER start the pump when people are standing next to it. A current
leak can result in electrical shock.
CAUTION
Run the pump for a short time (3–10 minutes) and confirm the
following:
•
Using an ammeter (clamp-on type), measure the operating
current at the L1 and L2 phase wires on the terminal.
COUNTERMEASURE: If the operating current exceeds the rated
value, pump motor overload may be a cause. Make sure the pump has
been installed under proper conditions as described in Installation.
wc_tx000111gb.fm
39
General Operation
•
CAUTION
WARNING
Using an AC voltmeter (tester), measure voltage at the terminals.
Supply voltage tolerance: within ±5% of rated voltage.
COUNTERMEASURE: If the supply voltage is outside the tolerance,
possible causes are the power supply capacity or an inadequate
extension cable. Look again at Electrical Wiring and make sure the
conditions are proper.
In case of very excessive vibration, unusual noise or odor, turn off the
power immediately and consult with your nearest dealer or Wacker
representative. Continuing to operate the pump under abnormal
conditions may result in electrical shock, fire, or current leakage.
Operation
The pump may become very hot during operation. Be careful not to
contact the pump accidentally to avoid being burned.
Make sure no extraneous objects such as pins, nails or other metal
objects are sucked into the pump. These can damage the pump or
cause it to malfunction, and can result in electrical shock or electrical
leakage.
When the pump is not used for an extended period, be sure to turn off
the power (circuit breaker, etc.). Deterioration of the insulation may
lead to electrical leakage, electrical shock, or fire.
In case of a power outage, turn off the power to the pump to avoid
having it start unexpectedly when the power is restored, presenting
serious danger to people in the vicinity.
Pay careful attention to the water level while the pump is operating. Dry
operation may cause the pump to malfunction.
Note: See section Operating water level, for the water level necessary
for operation.
Sharp bends in the hose, especially near its base, may cause air
pockets to form resulting in idle operation. Lessen the degree of
bending while continuing to operate the pump.

Threadlock and Sealant
8.
Threadlock and Sealant
Threadlocking adhesives and sealants are specified throughout this
manual by a notation of “S” plus a number (S#) and should be used
where indicated. Threadlocking compounds normally break down at
temperatures above 175°C (350°F). If a screw or bolt is hard to
remove, heat it using a small propane torch to break down the sealant.
When applying sealants, follow instructions on container. The sealants
listed are recommended for use on Wacker equipment.
