：The mark indicates an action that must be taken, or instructs how to perform a task. The symbol
inside the mark describes the precaution in more detail ("provide ground work", in the case of the
example on the left).
：The mark indicates a WARNING or CAUTION item. The symbol inside the mark describes the
precaution in more detail ("electrical shock", in the case of the example on the left).
●
: Operating the equipment improperly by failing to observe this precaution may possibly
cause injury to humans and other physical damage.
: Operating the equipment improperly by failing to observe this precaution may possibly
lead to death or injury to humans.
: Gives information that does not fall in the WARNING or CAUTION categories.
●
：The mark indicates a prohibited action. The symbol inside the mark, or a notation in the vicinity of
the mark describes the precaution in more detail ("disassembly prohibited", in the case of the
example on the left).
Be sure to thoroughly read and understand the SAFETY PRECAUTIONS given in this section before using
the equipment in order to operate the equipment correctly.
The precautionary measures described in this section are intended to prevent danger or damage to you or
to others. The contents of this manual that could possibly be performed improperly are classified into two
categories: WARNING, and CAUTION. The categories indicate the extent of possible damage
or the urgency of the precaution. Note however, that what is included under CAUTION may at times
lead to a more serious problem. In either case, the categories pertain to safety-related items, and as such,
must be observed carefully .
WARNING
CAUTION
NOTE
Explanation of Symbols:
Do not operate the product under any conditions other than those for which it is speci-
fied. Failure to observe the precaution can lead to electrical leakage, electrical
shock, fire, or water leakage, etc.

When transporting the product, pay
close attention to its center of
gravity and mass. Use an appropri-
ate lifting equipment to lift the unit.
Improper lifting may result in the
product damage, injury, or death.
Electrical wiring should be
performed in accordance with all
applicable regulations in your
country. Provide a dedicated earth
leakage circuit breaker and a
thermal overload relay for the pump.
Imperfect wiring or neglecting the
installation of proper equipment
will cause electrical leakage, fire,
or explosion at worst .
Use a power outlet that has a suf ficient rating and has been exclusively
provided for the pump. If the power outlet is shared with other equipment,
it can lead to an abnormal heat of the outlet and can cause fire as a
result.
Install the product properly in
accordance with this instruction
manual. Improper installation
may result in electrical leakage,
electrical shock, fire, water
leakage, or injury.
Provide a secure grounding
dedicated for the product. Never
fail to provide an earth leakage
circuit breaker and a thermal
overload relay in your starter or
control panel (Both available on
the market). If an electrical
leakage occurs by due to a
product failure, it may cause
electrical shock.

CAUTION
Do not scratch, fold, twist, make
alterations, or bundle the cable, or
use it as a lifting device. The cable
may be damaged, which may
cause electrical leakage, short-
circuit, electrical shock, or fire .
Be sure to provide a ground wire
securel y. Do not connect the
ground wire to a gas pipe, water
pipe, lightening rod, or telephone
ground wire. Improper grounding
could cause electrical shock.
Do not use the cabtyre cable, power
plug, or power outlet if it is damaged
or it is not closely fitted. Connect
every conductor of the cabtyre cable
securely to the terminals. Failure to
observe this can lead to electrical
shock, short-circuit, or fire .
Install the discharge pipe securely
so that no water leakage may
occur. In addition, It is suggested to
provide a stand-by pump in case of
flooding. Failure to do so may
result in damage to nearby walls,
floors, and other equipment .
When the product will be carried by
hand, decide the number of persons
considering the mass of the product.
When lifting up the product, do
not attempt to do it by simply
bowing from the waist. Use the
knees, too, to protect your waist .
This pump is neither dust-proof nor
explosion-proof. Do not use it at a
dusty place or at a place where
toxic, corrosive or explosive gas is
present. Use in such places
could cause fire or explosion.
If a hose is used for the discharge
line, take a measure to prevent the
hose from shaking. If the hose
shakes, you may be wet or
injured.
Prevent a metallic object or dust
from sticking to the power plug.
Adhesion of foreign object to the
plug could cause electrical
shock, short-circuit, or fire .
CAUTION
WARNING
Never try to operate the pump if
somebody is present in the pump
sump. If an electrical leakage
occurs, it can cause electrical
shock.
When changing power connection is
needed to correct the direction of
rotation, be sure to turn of f the
power supply (earth leakage circuit
breaker, etc.), and perform the work
after making sure that the impeller
has stopped completel y. Failure to
do so may lead to electrical
shock, short-circuit, or injury .
Never start the pump while it is
suspended, as the unit may jerk
and could lead to injury .
When inspecting the pump, be sure
to turn off the power supply (earth
leakage circuit breaker , etc.) so that
the pump may not start acciden -
tally. Failure to do so may lead to
a serious accident .
Do not operate the product under
any voltage other than described
on the nameplate with the voltage
variation limit within ±10%. If it is
operated with a generator , it is
strongly suggested not to operate
other equipment with the same
generator. Failure to observe
this caution may cause
malfunction and breakdown of
the product, which may lead to
electrical leakage or electrical
shock.
Do not touch the product with bare
hands during or immediate after
the operation, as the product may
become very hot during operation.
Failure to observe this caution
may lead to be burned.
Do not use the product in a liquid
other than water. Use in oil, salt
water or organic solvents will
damage it, which may lead to
electrical leakage or electrical
shock.
Do not run the product dry or
operate it with its valve (sluice or
gate valve) closed, as doing so
will damage the product, which
may lead to electrical leakage or
electrical shock.

CAUTION
WARNING
Absolutely turn of f the power
supply or disconnect the plug
before starting maintenance or
inspection. Do not work with wet
hands. Failure to observe these
cautions may lead to electrical
shock or injury .
After reassembl y, always perform a test operation before resuming use of the prod-
uct. Improper assembly can result in electrical leakage, electrical shock, fire,
or water leakage .
In case any abnormality (excessive
vibration, unusual noise or odor) is
found in the operation, turn the
power off immediately and consult
with the dealer where it was
purchased or Aquascape representa-
tive. Continuing to operate the
product under abnormal condi -
tions may result in electrical
shock, fire, or water leakage .
Do not disassemble or repair any
parts other than those designated
in the operation manual. If repairs
are necessary in any other than
the designated parts, consult with
the dealer where it was
purchased or Aquascape representa-
tive. Improper repairs can
result in electrical leakage,
electrical shock, fire, or water
leakage.

CAUTION
Do not allow foreign objects (metal
objects such as pins or wires) to

Failure to observe this caution
could cause it to malfunction or
to operate abnormally , which
may lead to electrical leakage or
electrical shock.
Do not use the product for hot or
warm liquid over 40°C , as doing so
will damage the product, which
may lead to electrical leakage or
electrical shock.
When the product will not be used
for an extended period, be sure to
turn off the power supply (earth
leakage circuit breaker , etc.).
Deterioration of the insulation
may lead to electrical leakage,
electrical shock, or fire .
