<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 or non-standard pH 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.
(5) Installation of Main Unit
Do not put any combustible material inside the control box.
If anchor installation is instructed for the equipment, do not install the equipment on a wood
or combustible floor. Install the anchor bolts securely.
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. This product conforms to laws and regulations in Japan. It may not be used in the export destination country
due to the laws and regulations there. 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) Dew Condensation and Water Leakage Countermeasures
Dew drops may occur depending on environment conditions including the raw water temperature
and the atmosphere in the installation location. If necessary, take measures to prevent dew
condensation, such as installing heat insulation.
Moreover, 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 ditch, and take any other
necessary steps.)

1.3.2 Feed Water Piping (Refer to Figure 4)
(1) Connect the feed water piping to the outlet side of the water softener. (The feed water piping
connection may be made to the water softener’s water sampling valve.)
(2) Precut the included the feed water tube, φ6 mm dia., to the length required for the
installation, and firmly inserts the end into the tube joint.
(3) Assemble the filter according to the following procedure. (Refer to Figure 5.)
[1] Take the filter casing assembly out of the bag.
Don’t fit the constant flow valve yet.
[2] The filter casing comes apart into two sections. To take them apart, rotate the top and
bottom sections in the direction of arrow.
[3] Remove the filter cartridge from the box (bag). Align the outlet end of the cartridge in the
center of the top casing. Insert the cartridge all the way, then firmly tighten the bottom
casing.
(4) Insert the feed water tube firmly into the joint on the bottom casing.
(5) Assemble the filter according to the following procedure. (Refer to Figure 5.)
[1] Slowly open the sample water collecting ball valve to bleed air from inside the filter
casing assembly.
[2] Close the sample water collecting ball valve about 10 seconds after opening the valve.
(6) Fit a constant flow valve that is attached to the bag in the end of casing. (Refer to Figure 6.)
NOTE
Be careful not lose the valve during installation.
A spare constant flow valve is attached to the filter cartridge box.
The spare may be used to replace a lost valve.
(7) Screw the filter casing into the bottom plate on the device with hand. Do not use a tool. There
is no need for concern about tightening it hard, since the O-ring at the end of filter casing
provides a good seal.
(8) Use the provided cable ties to bundle the φ6 mm dia. feed water tube to the φ8 mm dia.
drain tube. (Doing so prevents the φ8 mm drain tube form dropping out of the device if
external force is exerted upon it.)
Bundle them together about 150 to 200 mm (6 to 8 in. ) away from the bottom of the filter
casing. If it is tied too close to the filter casing, undue prying force may be exerted on the joint
and cause leakage.
When bleeding air from the filter casing assembly, water is vigorously discharged
from the end of the filter casing assembly. Perform work so that the water is not
splashed.
