Safety Information PST2/PSTF2 400

1.1 Operating and Electrical Safety

To reduce risk of electric shock, connect only to a properly grounded,
grounding-type receptacle.

WARNING

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.

Operation PST2/PSTF2 400

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

CAUTION

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

2.3 Installation

If the pump is used to drain a swimming pool, the pump must be
connected to a Ground Fault Interrupter (GFI).

WARNING

If the pump is used in fountains, the pump must be connected to a
Ground Fault Interrupter (GFI).

The pump must not be used when people are in the water.
Leakage of pump lubricants may cause pollution of water.
Proper plug must be provided according to local codes and standards.

Refer to wiring diagram.
Do not use this pump in liquids other than water, such as oil, salt water,

or organic solvents.
Use with a power supply voltage within ±5% of the rated voltage.
Do not use in water temperatures outside the range of 0–40°C

(32–104°F) which can lead to failure, current leakage or shock.
Do not use in the vicinity of explosive or flammable materials.
Use only in fully assembled state.

Note: Consult your local dealer or Wacker Neuson representative
before using with any liquids other than those indicated in this
document.

PST2/PSTF2 400 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: 20MW or greater.

Note: The reference insulation resistance (20MW or greater) is the
value when the pump is new or has been repaired. For the reference
value after installation, see the Periodic Maintenance table.

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

WARNING

damaged or cause injury.
When transporting the machine by hand, be sure to employ manpower

commensurate with the weight of the machine. To avoid back injury
when lifting the machine, 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,

CAUTION

causing current leakage, shock, or fire.

2.3.1 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.

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

CAUTION

shock.

Operation PST2/PSTF2 400

2.3.2 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
friction in the pump can lead to current leakage and shock.

CAUTION

2.3.3 Use the pump in the upright position. To prevent the strainer from
becoming submerged in mud, causing it to suck in sand or debris,
mount it on a block or other firm base.

2.3.4 If used in a permanent installation where the pump is not readily
accessible after installation, please contact Wacker Neuson for a
duplicate nameplate to be installed at the wellhead or on the control
box so that it will be readily visible.

2.4 Installing the Float (if equipped)

See graphic: wc_gr005664

wc_gr005664

2.4.1 Set the length of the float lead wire to the dimension indicated below.
Failure to set the correct lead wire length will lead to improper
operation of the pump.

Pump model Length “L”

PSTF2 400 150 mm (5.9 in.)

NOTICE: Install the float so that it moves freely up and down. If the
float binds or catches, it will cause the pump to operate improperly.

2.5 Electrical Wiring

Performing electrical wiring

Electrical wiring should be performed by a qualified person in accord
with all applicable regulations. Failure to observe this precaution not

WARNING

WARNING

only risks breaking the law but is extremely dangerous.
Incorrect wiring can lead to current 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
a current 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.

CAUTION

WARNING

CAUTION

Do not attach the grounding wire to a gas pipe, water pipe, lightning
arrester or telephone grounding wire. Improper grounding can result in
electrical shock.

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.

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.

NOTICE: 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.
