3. Installation

3.1 Requirements for installation

The ozone gas generator must be installed on the position which is even level with ground, and the material gas should be kept in dry condition excepting the following precaution.

In order to use the generator in steady stale, and to protect in from any damage, proper considerations for installation, piping for material gas, power supply and etc., are required to refer to well the following paragraphs (1) through (5).

(1) Prohibition places for installation.

Install the generator on the places excepting the followings in order to avoid damage and failure and also to keep safety operation.

① As this generator is designed as one of indoor type enclosure, it is not used where exposed to the water.

② Dusty place and environments where such corrosive gas as hydrogen nitride gas, sulfurous gas, or halogen

gas is flowing around the generator.

③ Environments where is in high temperature and high humidity, and place of radical temperature changes.

④ Places where strong vibration may be happed, or place of which is receiving continuos vibration.

⑤ Place under direct sun shine.

⑥ Places under or near strong magnetic field and electric field, and close to high frequency source.

⑦ Places which have not sufficient spaces to maintain and / or inspect the generator.

⑧ Process plant where explosive gas may be made up in the environment.

DANGER

・Explosion could result in death or serious injury.

Do not use the ozone generator in explosive environments.

・Do not apply sampling gas or water with over pressure than 98kPa to the

generator.

It may have a chance to make the generator to be broken or to have a burst the encloser or the parts, and also this may cause ozone leakage.

Notice: This product is a precision instrument, so it should be free from shock or vibration.

(2) Power supply

When supplying the power source to the generator, use the power source recommended to instrumentation.

If an inductive load and / or a large capacities load are connected to the power line, it can sometimes cause a surge problem for disturbing the measurement.

(3) Wiring for external control input signal

It is acceptable that a shielded wire is not always used for this signal wiring, but at last, twist pair wire should be usually used for this wiring.

However, do not use these twisted wires without shielding with power cable in conduit or open tray, and also avoid to wire it near heavy electric machine.

CAUTION

・In order to avoid dangerous and to protect the generator, install a no-fuse breaker at power line

outdoors.

3.2 Piping

s

In this section, requirements for pipings are described.

To prevent an ozone leakage, is required to do carefully the pipings for its gas line, and take care full the following items.

WARNING

・ As ozone is poisonous to human bodies, install the pipings as it may not have a leakage.

・ If water or liquid will flow backward, the generator may be failed in discharge unit, and it is

dangerous.

3.3 Specifications of ozone gas line

Regarding above specification, refer to Table - 1 below.

4. Operation

4.1 Procedure for manual operation

Operate the generator in accordance with the following procedure.

(1) Connect power plug cap to the socket for 100 V AC.

(2) Supply material gas into the generator and adjust flow rate to the specified one.

(3) Set Auto / Manual switch at "MANUAL."

(4) Rotate output adjusting trimmer (CONTROL ADJ.) to end of left side, and turn on the power switch.

(5) Adjust ozone concentration, using the trimmer. Regarding the position and ozone generation, refer to the performance curve on the ozonizer (ozonizer).

Note : The performance curve is only in reference of the concentration, it is affected by conditions for

Temperature Humidity and Material gas, and also is much changed itself.

4.2 Procedure for automatic operation

This automatic operation mode is used for performing the local operation of the ozone concentration or for controlling it to constant value, using the controller.

(1) Make wirings between controller output (4~20 mA) terminals and the input terminals on rear panel of the generator.

(2) Connect analog output (0~5V) of ozone monitor and the input of controller with cable.

(3) Set auto / manual switch at MANUAL position and turn output trimmer to zero.

(4) Adjust concentrations to required value, using ozone monitor and the controller.

(5) Supply material gas at flow rate of 5L/min, using attached air drier.

(6) Reset Auto / Manual switch at AUTO position and turn on the power.

This will make the generator to begin controlling the ozone concentration.
