SAFETY INSTRUCTIONS
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.
●
Indication of instructions in the Operating instructions
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:
ATTENTION!
●
Staff training
The personnel installing the pump must have the appropriate qualifications.
●
Risks incurred by failure to comply with the safety precautions
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.
In 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.
●
Safety precautions for the operator
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 information for inspection and assembly
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.
●
Unauthorized modification and manufacture of spare parts
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 operating methods
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.

●
Install a breaker of electric leakage
of under 30mA of rated sensitivity
to prevent electric shock.
●
The power cord must not be
bent, tied, pulled
or twisted by force.
Electric leakage,
electric shock, or fire
can occur.
●
Don’t clasp the power cord in transportation
and installation.
The damaged cord may cause
electric leakage or 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 Insulate the connection and cover it with rubber tape.
Then tightly cover it over four times
with friction tape.

●
Install the pump where the pump can be
conveniently checked or
repaired after installation.
If the space for the pump
is narrow, make the room
as described on the figure.
●
Install a stop valve on the suction side and the
discharge side of the pump
for easier pump maintenance.
●
When the power cord is extended, a voltage drop
that keeps the pump from operation may be caused.
Refer to the table for extended power cord.

운반·설치상의 주의사항
INSTALLATION
Installation process
- The pump should be installed indoors. In case of installing outdoors, set eaves to avoid exposure to wind
and rain, and prevent the pump from freezing.
- The pump should be in pressurized condition. (Recommended suction pressure: 0.2kgf/cm
To prevent dry running, the water tank should always be higher than the suction port of
ATTENTION!
the pump. Keep the minimum suction pressure at all times.
Vent air out from the suction side tank after cleaning it.
Even in a pressurized condition, running the pump with air in the tank or with suction
condition, the mechanical seal may be worn and consequently the rotational part may fall
down upon the stationary part.
Piping

)
ATTENTION!
- An elbow close to the pump suction flange should be avoided. Abnormal noise and vibration may occur.
- The piping should be adequately supported on both sides to reduce mechanical stress on the pump
- Make the piping run as short as possible and minimize the number of elbows
- Attach a strainer for filtering foreign objects to the end of the suction piping.
- Install a stop valve on the suction side and the discharge side of the pump to make pump maintenance
easier.
- Install the bypass on the discharge side to make pump maintenance easier.
- When the pressure tank is damaged, the discharge pressure can fluctuate or the piping can leak.
- To minimize noise of the pump, install a flexible joint on the suction piping and the discharge piping, and use
an anti-vibration rubber.
Piping direction
-Piping direction can vary depending on circumstances.
-Piping direction can be adjusted by loosening the union on discharge side.
-Tank is separately packed in shipping.

- Even in a pressurized condition, if an elbow is used, the suction piping should never be
of smaller diameter than the pump suction.

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 sup ply sh ould be i n a cco rdan ce wit h the rat ed val ue mar ked on th e n ame plat e.
- Before supplying power, check the following:
①
if the circuit breaker at power is suitable (under 30mA of rated sensitivity).
②
if the wiring is correct (connection and wire size).
③
If the connections with motor terminal are tightened (No operation with missing phase).
CAUTION!
In winter, install protections against cold weather.
●
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.
CAUTION! To prevent a fire, don’t cover the motor or pump with a blanket.

운반·설치상의 주의사항
USAGE
WARNING!
●
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.
CAUTION!
●
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.
●
●
Never touch the pump with
a bare hand when the pump
is operating or just stops
operating.
●
If water penetrates into the
motor, malfunction or electric
leakage may occur.
In electricity failure, disconnect the pump with the
power supply. Sudden start up may cause
physical damage.
●
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. In addition, the service life of the pump may be
shortened and malfunctions are highly likely to occur.
●
●
Never use hot water over 80°C in the pump.
Rubber parts and packing may be deformed,
and motor may
be damaged.
●
When staring up the pump after a long time of inactivity, check if the rotating
parts turn freely. Turn off the power and insert a screwdriver
in the notch on the motor shaft from the fan side.
Never alter an automatic item into non-automatic
Reconstruction of the pump is prohibited.
