Safety Cautions
Warning
Carry out the construction correctly in accordance with
electrical equipment technical standards, interior wiring
regulations, Building Standards and applicable regulations.
Work safely by confirming weight and form from the outline
drawing, catalog, etc. prior to hoisting.
Never use the product or install parts while it is hoisted. This is
very dangerous. The equipment may fall.
Fasten the pump securely with anchor bolts to prevent it
overturning.
Perform wiring work correctly as specified by electrical facility
technical standards and extension codes. Incorrect wiring
could result in electric shock and fires.
Install and ground an earth cable. Electric shock could occur
during accidents or electric leakage.
To prevent electric shocks, install a dedicated earth leakage
breaker.
Before wiring the motor, measure the insulation resistance
using an insulation tester (DC 500 V megger). Confirm that
there is a value of 5M
Ω
or more between the motor lead wire
and the ground.
Do not operate the pump for more than 1 minute with the
discharge valve left closed.
The pressure within the pump will rise, and the casing or plugs
may be damaged.
Do not touch the rotating parts such as the spindle, shaft
couplings, V-pulleys, etc. while the pump is running. Since
these parts rotate at high speed, doing so could result in
injury.
Disassembly and repair of the pump should only be performed
by specialist maintenance technicians. Otherwise,
error by
personnel could result in electric shock, and the pump
catching fire or operating abnormally and causing injury.
Always turn the power switch OFF before inspecting or
repairing the pump. Not doing so could result in the pump
starting up suddenly in auto operation, exposing personnel to
danger.
If there is a power failure, turn the power switch off.
Otherwise, the pump may start-up suddenly when the power
supply is resumed, exposing personnel to danger.
For disassembly and inspections, close the suction and
discharge valves, drain the casing drain, and ensure that the
pump pressure is not abnormal or negative. The pump may
undergo abnormal rotation while the work is incomplete,
resulting in damage to the casing.
In facilities with living matter (fish farms, fish preserves,
aquariums, etc.), always prepare a spare pump, as oxygen
deprivation may result due to pump failures.
