Warning
Securely install the ground wire and ensure to
carry out grounding work.
Otherwise, it may lead to an electric leak and/or electric
shock.
Do not connect the ground wire to a gas pipe or
water pipe.
Such a connection is illegal and leads to an electric shock,
explosion and/or fire.
Ensure that all electric wires are securely
connected.
Otherwise, it may lead to fire and/or an electric shock.
Before starting the maintenance or inspection
work, be sure to stop the pump and turn off the
main power of the panel board.
Otherwise, it may lead to an electric shock, injury, damage,
water leakage, and/or other problems.
Before starting the unit or carrying out
maintenance/inspection work, ensure that all the
relevant workers are informed of the operation and
that there are no workers in the dangerous zone
around the unit.
Otherwise, it may lead to an unforeseen accident.
Before rotating the pump shaft by hand to check its
smooth rotation, be sure to disconnect the main
power supply.
Otherwise, it may lead to injury and/or damage.
After turning on the power, do not touch any parts
of the water supply unit other than those required
for operation.
Otherwise, it may lead to an electric shock, injury, and/or
other problems.
Ensure to keep the cover of the control panel
closed during operation.
Otherwise, it may lead to an electric shock, fire, and/or other
problems.
Do not put your fingers or foreign objects into any
openings or rotating part of the motor during
operation.
Otherwise, it may lead to injury and/or damage.
Do not perform shutoff operation for more than one
minute continuously.
Otherwise, the temperature and pressure will increase inside
the pump, which may damage the pump and/or cause steam
to blow off.
Do not operate the unit if abnormal condition is
observed in any actions and movement or in any
parts, components, and others.
Otherwise, it may lead to injury, failures and/or various
accidents.
If you need to carry out work that requires
disassembly of the unit—such as replacement of
parts, repairs, or inspection, ask the vendor or the
service center specified by Teral inc.
If unskilled personnel carry out the work that requires special
knowledge, it may lead to an accident and/or failures.
Caution
Do not use the unit outside the range of the
product specifications.
Otherwise, it may lead to an electric shock, fire, water
leakage, failures, and/or other problems.
Do not use the unit at the power voltage other than
the specification.
An incorrect voltage may damage the control panel.
Do not use a single unit as the only means of
directly operating key facilities or sustaining life.
In the event of a failure, the water supply may stop. Ensure
to make a backup unit readily available.
Do not use the unit to deliver pure water.
Otherwise, pure water may be contaminated with impurities.
Pay special attention to nails when opening the
delivered container.
Otherwise, it may lead to injury and/or damage.
As for the installation environment of the unit,
strictly observe the installation instructions.
Otherwise, it may lead to premature failure.
Ensure that the floor at the unit’s installation place
is waterproofed and fitted with drainage.
Otherwise, it may lead to serious damage in the event of
leakage.
Only after detaching a companion flange from
each pump, screw a pipe into it.
Otherwise, it may lead to damage or water leakage.
Do not merge suction pipes.
Otherwise, it may hinder the normal operation.
Do not use any piping materials that are prone to
rust.
Otherwise, it may damage the unit.
Do not install different or other cables or control
wires in one pipe or duct.
Otherwise, it may damage the unit and/or other equipment.
Provide a ground electrode dedicated to the inflow
solenoid valve.
Otherwise, it does not function normally.
Do not step on the control panel, pump, or pipes.
Otherwise, it may lead to injury, damage, and/or other
problems.
Try to prevent the control panel and the motor from
being sprayed water.
Otherwise, it may lead to an electric shock, electric leak,
failures, and/or other problems.
