SAFETY INSTRUCTI NS
These instructions contain important information which must be followed when installing and operating the
pump. These operating instructions must therefore be read before assembly and commissioning by the installer
and the responsible operator. Both the general safety instructions in the "Safety precautions" section and those
in subsequent sections indicated with danger symbols should be carefully observed.
Safety precautions in these operating instructions which if not followed could cause personal injury are
indicated by the symbol: electrical warnings are indicated with:
The following symbol is used to indicate that by ignoring the relevant safety instructions, damage could be
caused to the pump/machinery and its functions:
● Indication of instructions in the perating instructions
The personnel installing the pump must have the appropriate qualifications.
● Staff training
Failure to comply with the safety precautions could result in personal injury, damage to the pump, or damage
to the installation. Failure to comply with the safety precautions could also invalidate any claim for damages.
n particular, lack of care may lead to problems such as:
- Failure of important pump or machinery functions,
-P ersonal injury due to electrical, mechanical and bacteriological causes.
● Risks incurred by failure to comply with the safety precautions
Existing regulations for accident prevention must be followed. Dangers caused by electrical energy
are to be excluded. Directives issued by the VDE German Association of Electrical Engineers and the local
electricity supply companies are to be observed.
● Safety precautions for the operator
The operator must ensure that all inspection and installation work is carried out by authorized and qualified
specialists who have carefully studied these instructions. Work on the pump/machinery should only be
carried out when the machine has been brought to a standstill.
● Safety information for inspection and assembly
Alterations to the pump or installation may only be carried out with the manufacturer's consent. The use of
original spare parts and accessories authorized by the manufacturer will ensure safety. The use of any other
parts may invalidate claims invoking the liabilitty of the manufacturer for any consequences.
● Unauthorized modification and manufacture of spare parts
The operating safety of the pump or installation supplied can only be guaranteed if it is used in accordance
with paragraph 1 of the operating instructions. The limiting values given in the catalogue or data sheet must
neither be exceeded nor allowed to fall below those specified.
● Unauthorized operating methods

● To prevent electric shock,
never plug in a power
cord under wet
conditions.
● nstall the pump where the pump can be
conveniently checked or
repaired after installation.
f the space for the pump
is narrow, make the room
as described on the figure.
● f the suction height exceeds 10m, it can lead to the
function of abnormal overpressure or damage to the
product. Use under 1kgf/cm2
(Example: The maximum height from the suction
must be under 10m)
● Do not connect to town water directly. t can lead to
malfunction or damage to the product.
● When the pump is highly likely to suck in dust or
foreign material, install a sand filter.
Failure to do so may cause a decline
in pressure and quantity
of pumped water, and
malfunction of the inverter.
●nstall a stop valve on the suction side and the
discharge side of the pump
for easier pump
maintenance.

● Before installation, repair or removal
of the pump, the power supply must be
disconnected.
● nstall a breaker of electric leakage
of under 30mA of rated sensitivity
to prevent electric shock.

● Pay special attention to extensions of the power cord.
Any electric leakage or disconnection in the extension
may cause electric shock.
● How to extend the power cord.
① Peel off the rubber/plastic insulation of the cable
as long as the connection terminal is.
② nsulate the connection and cover it with rubber tape.
Then tightly cover it over four times
with friction tape.
● Don’t clasp the power cord in transportation
and installation. The damaged cord may cause
electric leakage or shock.

company.
●The pump should not be connected directly to
public waterworks. Permission from the authority
should be granted. This could shorten the life of
the pump.
●When the pump is used for

a water purifier must be
installed

● Minimize the number of elbows to prevent water leakages in the piping and
to decrease water resistance. ●Set an alarm system to notify
the malfunction of the pump.
●Don’t expose the pump

otherwise faulty parts or an
electric shock may be
caused.

INSTALLATI N
Only a qualified electrician should connect cables. nstall a circuit breaker and connect
earth wire to prevent any electrical accidents including electric shock.
- The wiring of major parts including the motor and the pressure sensor is already finished. Wiring of earth
and other optional parts should be conducted according to the wiring diagram.
- The power supply should be in accordance with the rated value marked on the nameplate.
- Before supplying power, check the following:
①if the circuit breaker at power is suitable (under 30mA of rated sensitivity).
②if the wiring is correct (connection and wire size).
③f the connections with motor terminal are tightened (No operation with missing phase).

●When the pump remains inactive for a long time at temperatures lower than 0°C, the pump body must
be completely empty through the drain valve to prevent possible cracking of the hydraulic components.
●Bury the horizontal piping at least 30cm under ground.
CAUTI N! To prevent a fire, don’t cover the motor or pump with a blanket.
In winter, install protections against cold weather.

ATTENTI N!
●At first running, if you notice abnormal vibration, noise, or strange smell, turn off and disconnect the pump
from its source and contact the dealer or service center. Continuous operating in this case may cause fire or
electric shock.
●Don’t ever disassemble or alter the product.
-Fire, electric shock, or physical injury may occur.
-The pump must not be dismantled and repaired except by qualified skilled personnel.
- Contact our service center or dealer to have the pump repaired.
●When the power cord is broken, the replacement should be carried out by our dealer or other qualified personnel.
●After assembled, the pump should be put to test running.
ncorrect assembly may cause malfunction, electric leakage, or water leakage.

Part Description

●To prevent a fire, never wrap the motor of the pump head in a blanket or a cloth to
prevent freezing in cold weather.
The customers are liable for any damage caused by improper wrapping.
PERATING INSTRUCTI NS
●Never conduct a shut-off operating under dry running condition
and delivering no water.
The life of the parts may be shortened
and explosion may occur.
●n electricity failure, disconnect the pump with the
power supply. Sudden start up may cause physical
damage. ●f water penetrates into the motor,
malfunction or electric leakage
may occur.
●Disconnect the pump if it is unused
for a long time.
Otherwise old insulation
may cause electric
shock or fire.
●Never use the pump with liquids other than water.
A fire may be caused,when chemicals or flammable
liquids including petroleum, alcohol, or gasoline are
used. n addition, the service
life of the pump may be
shortened and
malfunctions are
highly likely to occur.

●
Never alter an automatic item into non-automatic
one. Reconstruction of the pump is prohibited.
● Any physical damage and property losses
cannot be compensated in this case.
●Never use hot water over 35℃in the pump. Rubber
