Applicable to All Water Treatment Equipment (Safety Information)
Document No.: 98-001-04
<Precautions for installation and use> —Safety information
When installing and using a piece of water treatment equipment, you are obligated as an operator to submit official
notification, and to install, construct and utilize your equipment strictly in compliance with applicable laws and regulations.
In order that your MIURA water treatment equipment can be put to safe and reliable use, it is crucial that in addition to
fulfilling these legal obligations, you also establish and implement a safety management system.
This section highlights situations where failure to follow MIURA guidelines
could lead to serious injury or death.
(1) Relocation & Resale
If you intend to relocate or sell your MIURA water treatment equipment, contact your dealer
or MIURA sales office in order that installation work can be carried out correctly and that
the peripheral equipment may be set up. In addition, ensure that Operation Manual and the
like are kept in order that they may also be provided to the new owner in the event of
resale.
(2) Prohibition of Modification without Permission
Customization or modification not recommended by MIURA may present safety problems
and is therefore prohibited. If you wish to modify your water treatment equipment, contact
your dealer or MIURA sales office in advance. It should be noted that MIURA will accept no
responsibility for the outcome of unapproved customization.
(3) Drain Piping
Ensure that drain piping is fixed securely in place to prevent it from moving in reaction to
drain discharge and that the end of the piping opens in a safe location such as a pit.
Failure to observe this precaution may lead to electric shock or other problems due to
splashing of water. Do not touch the drain piping as the discharged water may be high
temperature in some cases depending on the product used. Touching the drain pipe may
result in burns or other injury.
High concentration water may be discharged from the water treatment equipment
temporarily in some cases. Additional water treatment may be necessary to prevent lakes
and other bodies of water from being adversely affected depending on the volume of drain
and the water quality.
(4) Electrical Work
When connecting a power supply to the water treatment equipment, use wire of the
specified rating and ensure that the equipment are correctly grounded (Japanese D-type
grounding work or better). Furthermore, a dedicated power supply should be used, and an
earth leakage circuit breaker (with overcurrent protection) should be installed. If this
precaution is not observed, serious accidents such as electric shock and the outbreak of
fire may result.
NOTE
(1) Exporting from Japan
Under the Foreign Exchange and Foreign Trade Act, permission must be granted in advance by the Government of
Japan for products under export control to be shipped overseas. In addition, many countries have enacted regulations
and the like covering the import and usage of products from Japan—in certain cases, import and use of these products is
prohibited. Therefore, if you wish to export your water treatment equipment from Japan, contact your dealer or MIURA
sales office in advance.
(2) Water Treatment Equipment Installation
Ensure that the installation work for the water treatment equipment is carried out correctly as set forth in the applicable
MIURA Installation Manual. Furthermore, anybody who will work with the water treatment equipment should carefully
study the content of the Operation Manual in advance and ensure that it is fully understood.
(3) Water Leakage Countermeasures
Factors such as loose connectors and aging of pipe materials can lead to water leakage. It
is important that drain ditches be setup for the water treatment equipment and all peripheral
equipment. (In order to prevent water from leaking outside the room or downstairs, set up a
drain ditch that completely encloses the whole equipment, ensure that the floor itself is
waterproof, make the floor slope downward to the drain port, and take any other necessary
steps.)

4. Electrical Wiring
NOTE
•As the main power supply, install an independent earth leakage circuit breaker with overcurrent
protection (120 VAC rated voltage, 15A rated current, 30 mA rated sensitivity current) within 118”
of a trunk line branch point in the low-voltage indoor wiring.
•Connect a grounding wire at least as large as the power supply wire diameter (AWG14 or larger)
to terminal E on the equipment terminal block and perform the grounding work (D-class
grounding or better).
•Use a AWG14 or larger CV cable (or equivalent) as the power supply wire. Connect the ground
phase to terminal N on the power supply terminal block.
•Connect AWG16 VCTF cable (or equivalent) as the chemical feeder power supply wire.
•Use AWG16 or larger CVV cable (or equivalent) as contact output signal wires and chemical feed
pump drive signal wires. Connect the grounding wire from the chemical feeder to the FG terminal.
•Use AWG16 or larger CVV cable (or equivalent) as water level input wires and contact input
signal wires.
•Use AWG16 or larger shielded wire (AWG16 CVV-S cable is recommended) as flowmeter wires.
•To connect wires to the screw terminal block at the bottom of the equipment, use insulated crimp
terminals suitable for the terminal block width and screw size. Do not bend the terminals before
crimping them.
Do not operate the power switch with wet hands.
Failure to observe this precaution may lead to electric shocks.
During power source installation work, use a specified wire diameter for connection
and ensure that a ground is established.
(Japanese D-class grounding (third-class grounding) or better)
Furthermore, a dedicated power supply should be used and an earth leakage circuit
breaker (with overcurrent protection) should be set up. If this precaution is not
observed, serious accidents such as electric shock and outbreak of fire may result.
Protect wires in conduits.
Failure to observe this precaution may result in an electric shock due to damaged
insulation.
Turn OFF the power to all peripheral devices connected to the control board before
wiring the control board. Failure to observe this precaution may result in an electric
shock.

•For details about the ferrule terminals, refer to “4.2 Bar Terminals and Tools”.
•Protect communication wires (twisted-pair cable), power supply wires, and control wires in
conduits. Use separate conduits and wiring routes for the communication wires, power supply
wires, and control wires, respectively.
